UK SRS consultation: where it stands

Two consultations, asking two different questions. The Department for Business and Trade consulted on the standards themselves; the FCA consulted on who must apply them. Both have closed [1] [2].

DBT finished its half: UK SRS S1 and S2 were published on 25 February 2026 for voluntary use. The FCA has not finished its half. No policy statement responding to FCA CP26/5 had been published as at 14 August 2026.

The UK SRS consultation is two consultations, and they asked different things

Almost every page on this subject blurs them together. Keeping them apart is the whole of the story.

When people say “the UK SRS consultation” they are usually talking about one of two documents, published seven months apart by two different bodies, asking two questions that do not overlap at all.

01
DBT asked: are these the right standards?
The Department for Business and Trade published exposure drafts of UK SRS S1 and S2 on 25 June 2025 and consulted until 17 September 2025. The question was whether to endorse the ISSB’s IFRS S1 and IFRS S2 for UK use, and what to change about them. It received 209 responses and published the finished standards on 25 February 2026.
02
The FCA asked: who has to use them?
The Financial Conduct Authority published CP26/5 on 30 January 2026 and consulted until 20 March 2026. The question was whether to change the UK Listing Rules so that listed companies must report under UK SRS S2. It has published no response count and, as at 14 August 2026, no policy statement.
SOURCE: DBT dates and response count from the consultation outcome page and the government response document, 25 February 2026 [1][3]. FCA dates from the CP26/5 page [2].

The distinction matters because the two halves are in completely different states. DBT has finished. The standards exist, they are final, and anyone who wants to use them may. The FCA has not. Its proposals are proposals. Nothing in the UK Listing Rules has changed, and no company is required to report under UK SRS as a result of either consultation.

That is why a page which tells you “UK SRS becomes mandatory on 1 January 2027” is wrong twice over. The date is the FCA’s proposed commencement, and the FCA has not made the rule that would commence.

The sentence to take away

The standards are written and voluntary. The rules that would make them compulsory for listed companies are drafted and unmade. Everything else on this page is detail hanging off those two facts.

02 · The government’s half

The UK SRS exposure draft consultation, and what it actually asked

Twelve weeks in the summer of 2025, eleven questions, and a decision the government had already partly made.

The UK SRS exposure draft consultation ran from 1pm on 25 June 2025 to 11:59pm on 17 September 2025 [1]. It sat inside the Mansion House package of November 2024, in which the government set out how it intended to build “a world-leading sustainable finance framework”, and it was published alongside two sibling consultations — one on the transition-plan manifesto commitment, one on oversight of sustainability assurance providers.

The document put three things to consultees, and it is worth being precise about which was which, because only the middle one was genuinely open.

A
Whether to endorse IFRS S1 and IFRS S2 at all
Effectively settled before the consultation opened. The government described itself as “a strong supporter of the ISSB’s work” and the endorsement machinery — a Technical Advisory Committee and a Policy and Implementation Committee — had already been running.
B
Six specific amendments for a UK context
The live question, and the one this page spends most of its length on. Four came from the Technical Advisory Committee and two from the Policy and Implementation Committee.
C
Evidence on costs, benefits and future mandation
Explicitly forward-looking: the consultation said this evidence would “inform future government decisions when it considers whether to require entities to report information using the standards”. It was not itself a proposal to mandate anything.
SOURCE: the consultation’s own overview text and chapter structure, GOV.UK [1]; chapter descriptions from the government response, paragraphs 1.12–1.14 [3].

Who answered, and what they already report

The government received 209 responses: 170 through an online survey and 39 by email directly to DBT. 199 were organisations and 10 were individuals [3]. That figure is DBT’s, and it belongs to this consultation only — the FCA has never published a response count for CP26/5, and a page that attributes 209 responses to the FCA has confused the two consultations this page exists to separate.

Demographic detail is available for the 170 survey respondents. The largest single sector was financial and insurance services at 25% (42 of 170), followed by professional, scientific and technical activities at 11% (18 of 170). The rest came from manufacturing, utilities, retail and elsewhere in the real economy.

The most useful table in the whole response document is the one showing what those organisations already report against. It explains why the consultation produced so little argument about principle and so much about mechanics: most respondents were not being asked to start reporting. They were being asked to change the standard they report to.

What respondents already report underRespondentsShare of the 170
Streamlined Energy and Carbon Reporting (SECR) 7645%
TCFD-aligned rules through the Companies Act 5935%
The FCA’s TCFD-aligned Listing Rules 3118%
Requirements from other jurisdictions 1811%
SOURCE: Government response to the consultation on UK Sustainability Reporting Standards, DBT, 25 February 2026, Table 2 — entities may report under more than one framework, so the shares do not sum to 100% [3].

Respondents also split almost evenly on whether they were preparers or users of reports: 29% preparers only, 16% users only, 31% both, and 24% neither. A consultation answered largely by people who both write and read these reports is a different beast from one answered by lobbyists on one side of the table, and it shows in how technical the responses were.

If you want the underlying regime rather than the consultation about it, the UK SRS S1 and S2 overview covers what the two standards require; the legislation page covers the statutory machinery this consultation was feeding into.

03 · The centrepiece

What the UK SRS consultation actually changed, one amendment at a time

Six were proposed. One was withdrawn, one was changed into something quite different, and several more were added after the consultation closed.

Here is the thing almost every summary of this consultation gets wrong, and it is worth being blunt about it.

You will read, in a great many places, that UK SRS contains “six UK-specific amendments” to the ISSB baseline. The number is real and it is DBT’s own: the consultation document says, in terms, that “the government proposes 6 minor amendments to the standards for application in a UK context” [1]. Four came from the Technical Advisory Committee and two from the Policy and Implementation Committee.

But six is the number that was proposed, in June 2025. It is not the number that exists. By the time the standards were published in February 2026, one of the six had been withdrawn, one had been replaced by something broader, and at least three further changes had been made that nobody consulted on at all — because they arose from the consultation responses themselves, from the ISSB’s own December 2025 amendments, and from questions raised in PIC meetings after the consultation closed [3].

The government publishes no count of the final differences. What it publishes instead is Annex A — a paragraph-by-paragraph mapping between IFRS S1/S2 and UK SRS S1/S2, with an explicit scope note: “Where requirements in the standards are not included in the table, there are no differences between the two.” That table, not a headline number, is the authoritative answer to “what is different about UK SRS”. It is reproduced in full further down this page.

What follows is each of the six proposals, what it asked, how consultees answered, and what became of it — then the changes that were made without being proposed.

01TAC proposal · made as consulted

Reporting at the same time as the accounts

IFRS S1 paragraph E4 — deleted, with no UK SRS equivalent

MadeYear oneRemoves a relief

IFRS S1 lets a first-year reporter publish its sustainability information later than its financial statements. The TAC recommended removing that, and the government did.

A minority of respondents objected, wanting the flexibility. The majority agreed, on two grounds recorded in the response: that users value integrated reporting, and that UK entities already have years of practice at reporting climate information under the Companies Act and the Listing Rules. Connectivity between sustainability and financial reporting was one of the most commonly cited benefits of UK SRS across the whole consultation.

The practical effect is that a UK SRS reporter has no grace period. The sustainability report and the accounts land together, from the very first year.

02TAC proposal · overtaken by something broader

How long you may report on climate alone

IFRS S1 paragraph E5 → UK SRS S1 paragraphs E3 and E5

ChangedReliefNo time limit

IFRS S1 lets a first-year reporter disclose on climate only, deferring everything else. The exposure draft proposed extending that from one year to two. Most respondents agreed; those who objected said two years was an unnecessary delay, or that entities should be reporting on whatever is most financially material rather than assuming that is climate.

Then the proposal was overtaken. In PIC discussions after the consultation closed, a question arose about how UK SRS reliefs would interact with the equivalent provisions in the FCA’s Listing Rules. The government’s answer was not to pick a better number of years but to delete the time period altogether: the final standards, in its own words, “no longer specify how long the reliefs for non-climate reporting and Scope 3 reporting may be applied”.

For a voluntary reporter that means the relief has no expiry at all. For a future mandatory reporter it means the expiry is whatever the law or rule that mandates them says it is. The consultation asked “one year or two?” and the answer came back “that is the wrong question”.

03TAC proposal · withdrawn

The GICS requirement — consulted on, then dropped

Global Industry Classification Standard, IFRS S2

WithdrawnNot in Annex AISSB got there first

This is the most interesting item in the consultation and the one you will find nowhere else, because summaries written from the exposure draft never went back to check.

The exposure draft proposed removing IFRS S2’s requirement to use the Global Industry Classification Standard — a proprietary classification system — when disclosing certain information. Very few respondents disagreed. Of those who agreed, several made a pointed observation: the ISSB was itself consulting on the same problem, and the UK should align with whatever it decided rather than diverging on its own.

That is exactly what happened. The ISSB finalised its own amendment in December 2025, and its approach was “broadly consistent with the intention behind the UK’s proposed amendment”. So the government incorporated the ISSB’s change and “no longer recommends any further amendments to IFRS S2 regarding GICS beyond” it. Amendment 3 does not appear in Annex A, because there is no longer any difference to record.

It is worth sitting with that for a second. A UK-specific amendment was consulted on, supported, and then abandoned because the international standard-setter fixed the problem globally first. It is the clearest evidence available for the government’s stated priority of international alignment — and it means the count of UK divergences went down, not up, between consultation and publication.

04TAC proposal · made as consulted

The effective date, deleted on purpose

IFRS S1 paragraph E1 and IFRS S2 paragraph C1

MadeBoth standardsThe crux

IFRS S1 and IFRS S2 each carry an effective date of 1 January 2024. UK SRS carries none. The clauses were removed, in the government’s words, “to avoid any confusion with the introduction of any reporting requirements”. Almost no respondents disagreed.

This is the single most consequential thing about UK SRS and the reason this page exists. A standard with no effective date cannot commence. It can only be picked up voluntarily, or switched on by something else — a Companies Act requirement, an FCA rule, or another authority with the power to impose reporting duties.

So when the FCA proposes rules “coming into force from 1 January 2027”, that date is not in UK SRS and never was. It is a date in a draft FCA rule. The standards themselves are, as the government put it, available to voluntary reporters immediately — and to everyone else, never, until somebody legislates.

05PIC proposal · made · 70% support

SASB: “shall refer to and consider” becomes “may”

UK SRS S1 paras 55(a) and 58(a); UK SRS S2 paras 12, 23 and 32

Made122 of 175 agreedTwo standards

IFRS S1 tells an entity it shall refer to and consider the applicability of the SASB Standards. UK SRS S1 says may. The same change was made in UK SRS S2 for the Industry-based Guidance on Implementing IFRS S2.

70% of respondents (122 of 175) agreed. Those in favour largely argued that using SASB material should be a business decision. Those against worried about comparability, and many on both sides asked for the change to be revisited once the ISSB completes its own work on the industry guidance.

One detail in Annex A is easy to miss and matters if you are drafting. Paragraphs 37 and B65(d) of UK SRS S2 still say “shall” — because they refer to industry-based metrics in general, not to the SASB guidance document specifically. You are still required to consider industry-based metrics. You are merely no longer required to consider that publication when deciding what they are.

06PIC proposal · made and extended · 83% support

Tying the reliefs to whenever reporting actually starts

UK SRS S1 paras 73A, 73B and E5; UK SRS S2 para C6

Made138 of 166 agreedMost-supported

The transitional reliefs in IFRS S1 and S2 are keyed to “the first annual reporting period in which the entity applies the Standard”. If a standard has no effective date, that phrase has nothing to bite on. The proposal was to link the reliefs to the date any reporting requirement comes into force instead.

It was the most strongly supported proposal in the entire consultation — 83%, or 138 of 166 respondents. But respondents also said the drafting was not clear enough about whether and how a regulator could control the reliefs, and about what an entity could claim while using them.

So the government went further than it had consulted on. It added paragraph E5 to UK SRS S1 and paragraph C6 to UK SRS S2, each stating that the availability of the reliefs is subject to the Companies Act, the FCA, “or any other UK regulatory or government entity with the means to enact reporting requirements” — and then added paragraphs 73A and 73B to deal with the consequences for compliance statements. Those are the next banner.

Three changes nobody consulted on

The remaining differences in Annex A were not in the exposure drafts. They were made afterwards, in response to what consultees said, to the ISSB’s December 2025 amendments, and to questions raised in PIC meetings after the consultation had closed. The government flags this itself: “the government encourages stakeholders to take note of the final amendments that the government has made”.

07Added after consultation

Financed emissions: an explain mechanism that did not exist before

UK SRS S2 paragraph B59A — new, no IFRS S2 counterpart

New paragraphFinancial institutionsComply or explain

Question 2 asked whether a financial institution should be able to use financed-emissions data from a different reporting period to the related financial statements. It was the most evenly divided question in the consultation: 50%, 73 of 146 respondents, agreed. Question 3 drew 82 responses, many of them arguing that the requirement was simply not practicable on the timetable it assumed.

Rather than grant a blanket exemption, the government asked the TAC for fresh advice, got it on 26 January 2026, and added a new paragraph. Paragraph B59A requires an entity that cannot reliably estimate financed emissions for the same period as its financial statements to explain why — a duty to account for the gap rather than permission to leave one.

It is the only wholly new substantive requirement UK SRS adds to the ISSB baseline. Every other difference in Annex A removes something, softens something, or renumbers something.

08Added after consultation

What you may call compliance, once you have taken a relief

UK SRS S1 paragraphs 73A and 73B — new

New paragraphsCompliance statementAsymmetric

Paragraph 73A does two things, and they are not symmetrical — which is why so many summaries state it wrongly.

First: an entity using the climate-only relief at UK SRS S1 paragraph E3 may not assert compliance with UK SRS S1, and must disclose that it has used the relief. Second: an entity using any one or more of the three reliefs — S1 paragraph E3, S2 paragraph C3 on GHG Protocol alternatives, S2 paragraph C4 on Scope 3 — is not prevented from asserting compliance with UK SRS S2, provided it discloses which reliefs it used.

So the climate-only relief costs you an S1 compliance statement and nothing else. The Scope 3 and GHG Protocol reliefs cost you nothing at all, so long as you say you are using them. Paragraph 73B then puts the whole question under whichever authority ends up requiring the reporting. There is a working calculator for this below, because the combinations are genuinely hard to hold in your head.

There is one further category, which Annex A handles in a single row: the ISSB’s own targeted amendments of December 2025. Because UK SRS S2 was issued after they were made, it simply contains them — amended paragraphs 29(a)(ii), 29(a)(vi)(2), B21–B22, B24, B28, B37, B59, B62(a) and B63(a), and added paragraphs 29A–29C, B62A and B63A. The government records them as “fully consistent” with the ISSB’s versions.

This matters for a specific reason. Those December 2025 amendments are where the extended jurisdictional relief on Global Warming Potential values and the clarified relief on using a methodology other than the GHG Protocol come from. You will see both described as UK amendments. They are not: they are ISSB changes that UK SRS inherited by being published later. Annex A does not list them as differences, because they are not differences.

04 · The regulator’s half

FCA CP26/5 — the consultation on who must apply the standards

Thirty January to twenty March 2026. Closed, unanswered, and the reason anyone searches for this subject at all.

FCA CP26/5, Aligning listed issuers’ sustainability disclosures with international standards, opened on 30 January 2026 and closed on 20 March 2026 [2]. It proposes changing the UK Listing Rules so that listed companies report against UK SRS S2 instead of the FCA’s existing TCFD-aligned rules.

The cleanest available summary of what it proposes is not in the consultation paper. It is in DBT’s response document, at paragraph 1.15, written by the other regulator in the room:

“The FCA’s consultation proposes that in-scope listed entities will disclose information about their climate-related risks and opportunities in accordance with UK SRS S2 and must apply the specific provisions in UK SRS S1 as relevant to those disclosures. UK SRS S2 (excluding Scope 3 greenhouse gas (GHG) emissions reporting) would be mandatory. Scope 3 GHG emissions and information about sustainability-related risks and opportunities beyond climate would be captured under a ‘comply or explain’ approach. The FCA proposes a phased implementation approach, taking effect from 1 January 2027.”

Government response to the consultation on UK Sustainability Reporting Standards, DBT, 25 February 2026, paragraph 1.15

Four things are worth pulling out of that.

01
It is S2 that would be mandatory, not S1
S1 comes in only “as relevant to those disclosures”. This is not a proposal that listed companies report the full sustainability scope.
02
Scope 3 sits outside the hard requirement
Scope 3, and everything beyond climate, would be comply or explain. The FCA’s own words are that it proposes this “for some of the more challenging or new aspects of reporting”.
03
Implementation would be phased
A phase-in, not a cliff edge — and the phasing itself is one of the things the policy statement would have to settle.
04
1 January 2027 is a proposed commencement
The FCA’s own sentence is “we … aim to publish a Policy Statement in autumn 2026, subject to the final UK SRS, with the rules coming into force from 1 January 2027”. Two hedges in one sentence.
SOURCE: FCA CP26/5 landing page, last updated 5 June 2026 [2]; DBT government response para 1.15 [3].

The framing the FCA chose, and why it is worth quoting

CP26/5 does not present itself as a climate measure. It presents itself as a competitiveness measure. The FCA says the proposals support “the Government’s Leeds Reforms as well as the UK’s position as a global financial centre, by boosting comparability across markets and reducing duplicative rules”.

That is a deliberate choice of ground, and it tells you something about how the FCA expects to defend the policy statement when it arrives. A rule justified on comparability and the removal of duplication is a rule whose case does not depend on the climate argument holding politically. It is also, for what it is worth, the single freshest sourced sentence available on this subject, and no other page ranking for these terms currently carries it.

The population, and the number everybody quotes wrongly

CP26/5’s Cost Benefit Analysis sets out the affected population at paragraph 43, and it is a three-part figure, not the one-part figure usually quoted:

GroupCompaniesWhat CP26/5 would require
Affected in total around 600 “Based on our analysis of the Official List as of January 2025, around 600 listed companies would be affected by our proposals”
Required to comply
UKLR 6, 16 and 22
515 “will be required to comply with our UK SRS proposals and therefore face most costs and generate most benefits of our intervention”
Lighter touch
UKLR 14 and 15
89 “our proposals will require disclosure of the climate or sustainability reporting requirements that apply in the company’s primary listing location or place of incorporation, or which they voluntarily adopt”
SOURCE: FCA CP26/5, Cost Benefit Analysis, “Key assumptions” paragraph 43, with the same 515 repeated at CBA paragraphs 2 and 87 [2].

So “515 companies are in scope of CP26/5” is wrong: the scope is around 600, and 515 is the subset that would have to comply. The other 89 get a signposting duty about which regime they actually follow — a real obligation, and a completely different one. If you run a depositary receipt programme or a secondary listing, every page that quotes the 515 has silently left you out.

The five categories are UKLR 6 (commercial companies), UKLR 14 (secondary listing), UKLR 15 (depositary receipts), UKLR 16 (non-equity shares and non-voting equity shares) and UKLR 22 (the transition category), and the FCA says the requirements would apply “with some variation depending on the category” [4]. One thing to watch if you are reading older material: the premium and standard listing segments no longer exist. They were replaced by the UK Listing Rules categories on 29 July 2024, so any page describing CP26/5’s scope as “premium listed companies” is working from a superseded structure.

Does FCA CP26/5 reach you, and on which branch?

Two questions, run against the category split in CP26/5’s own Cost Benefit Analysis — including the 89-company branch most summaries drop.

Nothing is sent anywhere. The whole check runs in your browser.

Answer for the securities that are actually admitted to the Official List. A company can sit in more than one category, in which case run it twice — the FCA says the requirements vary by category, so the answers are not interchangeable.

And read the verdict as what it is: an account of a proposal. Nothing here is in the Listing Rules today.

06 · The outcome

The standards as published — voluntary, and with no effective date

The consultation produced a finished product. What it did not produce is any obligation to use it.

UK SRS S1 and UK SRS S2 were published on 25 February 2026. GOV.UK’s guidance page states the position in one sentence: “The standards are available for voluntary use, by any entity that chooses to do so” [5].

The government response is, if anything, broader: the standards “are available for any entity to use, in whole or in part, as they see fit”. Not just any entity — any part of them.

That is an unusual thing for a reporting standard to say, and it follows directly from Amendment 4. Delete the effective date and you delete the mechanism by which a standard imposes itself. What is left is a document anyone may adopt, on any timetable, to any extent.

What “no effective date” means in practice

Annex A states it for each standard in almost identical words. For S1: “The effective date has been removed from UK SRS S1, meaning that entities can apply the Standard when they choose to do so, unless required by UK law or regulations to apply it from a specific reporting period.” For S2, the same. What survives in both is the requirement that S1 and S2 are applied at the same time — retained at S1 paragraph E2 and S2 paragraph C2.

Four consequences follow, and they are the practical content of the whole consultation.

Nobody is late
There is no date by which a UK entity should have adopted UK SRS. An organisation that has done nothing is fully compliant with everything that currently applies to it.
You cannot half-adopt by accident
S1 and S2 go together. An entity applying S2 must apply S1 at the same time — paragraph C2 of S2 kept that rule even after the effective date went.
The reliefs have no clock
A voluntary reporter can use the climate-only and Scope 3 reliefs indefinitely: the government removed the time periods rather than lengthening them.
Somebody else has to switch it on
Paragraphs 73B, E5 and C6 name who: the Companies Act, the FCA, or another UK body with the power to enact reporting requirements. None has.

If you want the standards themselves rather than the consultation about them, they sit on GOV.UK as published documents, and the UK SRS reporting page walks through what applying them involves.

07 · The gap

What the policy statement must still settle

Five open questions, as at 14 August 2026, and none of them has a published answer.

This is the section that justifies the page. Everything above is a description of documents that exist. This is a description of a document that does not.

As at 14 August 2026, the FCA has published no policy statement responding to CP26/5. Its consultation page still carries the original sentence — “we will review the feedback and aim to publish a Policy Statement in autumn 2026, subject to the final UK SRS, with the rules coming into force from 1 January 2027” — and that page has not been substantively updated since 5 June 2026. Nothing has replaced it, superseded it, or brought the date forward.

Read the sentence carefully and it contains two conditions and a target, not a commitment. “Aim to publish” is not “will publish”. “Subject to the final UK SRS” is a condition that has since been satisfied — the standards were published five days before the consultation closed — but it was written when it had not been. And “autumn 2026” is a season, not a date.

Here is what that document, whenever it arrives, will have to decide. Each of these is genuinely open: the consultation asked about it, and no published answer exists.

01
Whether the rules are made at all, and in what form A consultation is not a commitment. The FCA can confirm, modify or abandon. Nothing obliges it to proceed, and it has published no indication of which way it is going. CP26/5 is a consultation paper, not a draft instrument in force
02
The commencement date, and whether 1 January 2027 survives The proposed date is now under five months away from the season in which the policy statement is meant to appear. A rule published in, say, November 2026 to commence on 1 January 2027 would give in-scope companies a matter of weeks. “Rules coming into force from 1 January 2027” — proposed
03
What the phasing actually looks like The FCA proposes “a phased implementation approach”. Which categories phase in when, and whether the phasing runs by company size, by category or by disclosure, is not settled on the face of the consultation. DBT government response para 1.15
04
How comply-or-explain is policed Scope 3 and beyond-climate matters would be comply or explain. What counts as an adequate explanation, and what the FCA does about an inadequate one, is the difference between a real obligation and a formality. “For some of the more challenging or new aspects of reporting”
05
How the UK SRS reliefs interact with the Listing Rules This is the question that produced paragraphs 73A, 73B, E5 and C6 in the first place. UK SRS hands the availability of its reliefs to the regulator; the regulator has not yet said what it will do with them. Government response para 1.22 — the PIC raised exactly this

There is a sixth question that nobody is obliged to answer, but which follows from the fifth: what happens to the 89 companies on the lighter-touch branch if the FCA changes its mind about the split. The Cost Benefit Analysis treats them as a distinct population with a distinct duty, but the consultation is explicit that requirements would apply “with some variation depending on the category”, and the variation itself is not fixed.

Dated negative, stated deliberately

A page that tells you what has not happened is more useful here than one that speculates about what will. As at 14 August 2026: no FCA policy statement; no changes to the UK Listing Rules; no effective date in either standard; and no requirement on any UK entity to report under UK SRS. Every one of those sentences was true when this page was last verified, and each will stop being true on a date nobody has published.

A letter setting out its proposed approach to how UK SRS reliefs would interact with the Listing Rules — the question the PIC had raised after the consultation closed. Its contents became paragraphs 73A, 73B, E5 and C6.

The TAC delivers fresh advice on financed emissions
Requested by the government after consultation responses to questions 2 and 3 showed the financed-emissions timing requirement was widely thought impracticable. The advice produced UK SRS S2 paragraph B59A.

The FCA publishes CP26/5
Consultation on aligning listed issuers’ sustainability disclosures with international standards — opened while the final UK SRS were still unpublished, which is why the FCA’s own timing sentence is conditional on them.

Last update to the CP26/5 page
The FCA’s CP26/5 page is updated, and still reads “aim to publish a Policy Statement in autumn 2026”. Nothing has been added to it since.
Autumn 2026Proposed
The FCA “aims to” publish its policy statement
A season, an aim, and a condition — “subject to the final UK SRS”. Not published as at 14 August 2026.
Later in 2026Proposed
A consultation on Modernising Corporate Reporting
Promised in February 2026 as coming “later this year”. It is the route by which UK SRS could reach private companies. Not launched as at 14 August 2026.
1 Jan 2027Proposed
The date CP26/5 proposes its rules would come into force
Phased, and conditional on a policy statement that does not yet exist. This is the date most coverage reports as the date UK SRS “becomes mandatory”. It is a proposal in an unanswered consultation.

Notice what the rail shows once the two kinds of entry are separated: ten things have happened and three have not, and everything that has happened is DBT’s or the ISSB’s. Every outstanding item belongs to the FCA or to a programme that has not yet consulted. For a fuller view of how this sits against the other UK reporting regimes, see the UK SRS timeline.

09 · Reach

Who the UK SRS consultation actually reaches, and when

Three populations, in three completely different positions. Most confusion about this subject comes from treating them as one.

Ask “does UK SRS apply to me” and the honest answer today is no, to everybody — there is no UK entity under any legal obligation to report against UK SRS S1 or S2. But that flat answer hides three quite different futures, and which one you are in depends on facts you already know about yourself.

Listed, in UKLR 6, 16 or 22
The 515. If CP26/5 is made as proposed, you report under UK SRS S2 on a phased basis from 1 January 2027, with Scope 3 and beyond-climate matters comply or explain. You are the population the consultation was actually about.
Listed, in UKLR 14 or 15
The 89. You would disclose which climate or sustainability regime applies to you in your primary listing location or place of incorporation — a signposting duty, not a UK SRS reporting duty.
Everybody else
Private companies, LLPs, AIM companies, charities. Outside CP26/5 entirely. The only route to UK SRS for you runs through the Companies Act, via the Modernising Corporate Reporting programme, which has not consulted yet.

It is worth noticing how small the mandatory population would be. Around 600 listed companies sit inside CP26/5 at all. By comparison, SECR reaches roughly 19,900 UK entities and has done since 2019. Whatever UK SRS becomes, the consultation that has closed would not make it a broad-based reporting regime — it would make it a listed-markets one.

That is precisely why the Modernising Corporate Reporting programme matters more to most readers of this page than CP26/5 does. If UK SRS ever reaches private companies, it will be through the Companies Act, and the government has said MCR “will include consideration of the need for requirements within the Companies Act for private entities to report against UK SRS”. That consultation was promised for 2026 and, as at 14 August 2026, has not appeared.

The decision flow, across all three regimes

Because most organisations asking about UK SRS are already inside SECR, ESOS or both, the useful question is not “does UK SRS apply” in isolation but which of the three regimes reaches you and in what order. This is the site’s standard scope diagram.

Two cautions on reading it. The UK SRS S2 branch is marked Proposed because that is what it is — it describes CP26/5, not a rule. And the SECR and ESOS branches are current law, which means an organisation can quite easily be in scope of two regimes today and a third only hypothetically. If the SECR thresholds are the live question for you, the thresholds guide works through them properly.

10 · The reference

How UK SRS differs from the ISSB baseline, paragraph by paragraph

Annex A of the government response, reproduced in full. This is the authoritative answer, and it does not come with a headline number.

Annex A carries its own scope note, and it is the most useful sentence in the document: “Where requirements in the standards are not included in the table, there are no differences between the two.”

So this is not a summary of the main changes. It is the complete set. If a paragraph is not below, UK SRS says exactly what the ISSB standard says.

One general change applies throughout and is not tabulated: references to IFRS Sustainability Disclosure Standards become references to UK Sustainability Reporting Standards. Additional UK paragraphs also follow the ISSB’s own December 2025 numbering convention, deliberately, so the two documents stay comparable paragraph for paragraph.

IFRS S1 → UK SRS S1

IFRS S1UK SRS S1What changed
55(a), 58(a)55(a), 58(a) Shall refer to and consider” the applicability of the SASB Standards becomes “may refer to and consider”.
73A New. An entity using the paragraph E3 climate-only relief may not assert compliance with UK SRS S1 and must disclose its use of the relief. It is not prevented from asserting compliance with UK SRS S2 while using any of the three reliefs (S1 E3, S2 C3, S2 C4), provided it discloses them.
73B New. Application of UK SRS S1, including the compliance statement, is subject to regulation or legislation under the Companies Act, by the FCA, “or by any other UK regulatory or government entity with the means to enact reporting requirements”.
E1, E2E2 The effective date of 1 January 2024 is removed. Entities apply the Standard when they choose, unless required by UK law or regulation to apply it from a specific period. The requirement to apply S1 and S2 at the same time is retained.
E3E1 The reference to the date of initial application is removed, because there is no longer an effective date to hang it on. The rule that no comparatives are required in the first annual reporting period is retained.
E4 Removed outright. IFRS S1 permitted a first-year reporter to publish its sustainability disclosures after its financial statements. UK SRS S1 has no equivalent.
E5E3, E5, 73A The climate-only relief is retained but the “first annual reporting period” limit is removed — availability is instead set by legislation or regulation (new paragraph E5). The duty to disclose use of the relief moves to paragraph 73A.
E6E4 E4(a) is unchanged: no climate comparatives in the first annual reporting period. E4(b) is amended: comparatives for wider sustainability matters are required in the second annual reporting period in which the entity no longer applies the paragraph E3 relief.

IFRS S2 → UK SRS S2

IFRS S2UK SRS S2What changed
12, 23, 3212, 23, 32 Shall refer to and consider” the Industry-based Guidance on Implementing IFRS S2 becomes “may”. Paragraphs 37 and B65(d) keep “shall” — they refer to industry-based metrics generally, not to that publication.
B59A New. Where it is impracticable to reliably estimate financed emissions for the same period as the related financial statements, an entity must explain why it has not disclosed in line with paragraph B59.
C1, C2C2 The effective date of 1 January 2024 is removed. The requirement to apply UK SRS S1 at the same time is retained.
C1A, C1B, C6 Not needed. These handle the transition to the ISSB’s December 2025 amendments; UK SRS S2 was issued afterwards and simply contains them, “fully consistent” — amended paragraphs 29(a)(ii), 29(a)(vi)(2), B21–B22, B24, B28, B37, B59, B62(a), B63(a), and added paragraphs 29A–29C, B62A, B63A.
C3C1 The date-of-initial-application reference is removed; the first-period comparatives rule is retained.
C4C3, C4, C6 The two transitional reliefs are split. C3, the GHG-Protocol-alternative relief, keeps its first-annual-reporting-period limit. C4, the Scope 3 relief, loses it — availability set by legislation or regulation instead. New C6 makes both subject to UK law or regulation.
C5C5 Continued use of both reliefs for comparative information in later periods is still permitted, and UK SRS S2 adds that use must be disclosed alongside the statement of compliance, per UK SRS S1 paragraph 73A.
SOURCE: Government response to the consultation on UK Sustainability Reporting Standards, DBT, 25 February 2026, Annex A — “Summary of differences between IFRS S2 and UK SRS S2” [3].
The two amendments that are not there

Neither the GICS change nor the Global Warming Potential and GHG Protocol methodology reliefs appear as differences in Annex A, and both are routinely described as UK amendments. They are not. GICS was withdrawn once the ISSB made its own amendment; the GWP and methodology reliefs are ISSB changes from December 2025 that UK SRS S2 inherited by being published afterwards. A difference table is the right place to settle this: if a change is not in Annex A, it is not a UK divergence.

Two of the rows above are hard enough to apply that they get their own working tools below: what you may claim once you have taken a relief, and which reporting periods need comparative information. Both compute from the paragraphs in these tables rather than from a lookup.

11 · What you may claim

Take a relief, and what can you still call compliance?

Paragraph 73A is asymmetric, and almost every summary of it states the symmetric version.

There are three transitional reliefs across the two standards, and the compliance statement you may make depends on which you use, not how many.

The climate-only relief at UK SRS S1 paragraph E3 costs you an S1 compliance statement. The Scope 3 relief at S2 paragraph C4 and the GHG-Protocol-alternative relief at S2 paragraph C3 cost you nothing at all — provided you disclose that you are using them.

Nothing is sent anywhere. The whole calculation runs in your browser.

12 · Comparatives

Which reporting periods need comparative information?

Paragraph E4(b) does not start its clock at first application. It starts it when you stop taking the climate-only relief.

This is the single most misread row in Annex A. IFRS S1 required comparatives for wider sustainability matters in the second annual reporting period. UK SRS S1 requires them in the second annual reporting period in which the entity no longer applies the paragraph E3 relief — which can be years later, or never.

Because the relief itself lost its time limit, a voluntary reporter reporting on climate alone holds that clock at zero indefinitely. The grid recomputes as you change the inputs.

13 · The scenarios

What happens if the policy statement slips

Not a prediction. A description of what each outcome would mean, so you can recognise which one you are in when it arrives.

The FCA said autumn 2026 and it said “aim to”. Autumn is not over. But the proposed commencement is 1 January 2027, and the gap between those two things is now small enough that the sequencing itself is a live question. Four things can happen. None of them is more likely than the others on any published evidence, and this page does not pretend otherwise.

A
The policy statement lands in autumn, with 1 January 2027 intact The rules are made broadly as consulted. In-scope companies get somewhere between a few weeks and three months of notice before a phased regime begins. The phasing is what would make that workable, and the phasing is the part nobody has seen. What CP26/5 currently describes
B
The policy statement lands, but commencement moves The most common outcome for a rule of this size. Note that the FCA has room to do this without contradicting itself: “coming into force from 1 January 2027” is loose drafting, and a phased approach starting later still starts “from” somewhere. Watch the word “from”
C
The policy statement slips past autumn At which point the 1 January 2027 date becomes untenable on notice grounds alone, and the practical question becomes which reporting year is the first. Nothing would change for anybody in the meantime: the existing TCFD-aligned Listing Rules continue to apply. The status quo persists by default
D
The proposals change materially, or are not made A consultation can end in no rule. If the FCA concluded the case was not made, the UK SRS standards would remain exactly what they are now — published, voluntary, and available to any entity that wants them. A consultation is not a commitment

What follows from all four is the same practical point, and it is the reason this page does not end in a scare. Under every scenario, the standards themselves are unchanged and available today. An organisation that wants to be ready is not waiting for the FCA — it can apply UK SRS voluntarily, in whole or in part, now, and use the reliefs indefinitely while doing so. The policy statement decides who is compelled, not what good looks like.

The one thing worth actively watching is the Modernising Corporate Reporting consultation, because it reaches far more organisations than CP26/5 does. If UK SRS is ever going to apply to a large private company, that is the document that will say so. It was promised for 2026 and has not appeared.

14 · Taking part

How to respond to a UK consultation, and what actually happens to responses

This one is closed. The next one is not, and the record shows responses moved real outcomes here.

Both consultations on this page have closed, so there is nothing to respond to today. But the Modernising Corporate Reporting consultation is promised, the FCA consults continually, and the record of this particular exercise is unusually good evidence that responding is worth the time.

What responses actually changed here

It is easy to be cynical about consultations. On this one, the paper trail does not support the cynicism. At least four substantive changes are directly traceable to what consultees said:

01
Paragraph B59A exists because respondents said the rule was impracticable
Question 3 drew a range of views from 82 respondents about financed emissions. The government went back to the TAC for fresh advice on 26 January 2026 and added a new paragraph to UK SRS S2 as a result.
02
Paragraphs 73A and 73B exist because respondents said the drafting was unclear
On question 6, respondents agreed with the principle but “raised questions on the specific wording of this amendment as drafted”. The government redrafted and added two paragraphs.
03
The two-year relief became no limit at all
A change of approach, not of number, prompted by a question the PIC raised after the consultation closed about how the reliefs would interact with the Listing Rules.
04
A proposed amendment was withdrawn on consultees’ reasoning
Respondents on the GICS amendment argued the UK should align with whatever the ISSB decided rather than diverge. It did.
SOURCE: Government response paragraphs 1.20, 1.22, 1.25–1.28 and 1.37–1.38 [3].

What a UK consultation response looks like

UK government consultations are typically run through an online survey with a parallel email route, and both count. On this one, 170 of the 209 responses came through the survey and 39 by email direct to DBT. Neither route was privileged, and the email responses are represented throughout the response document alongside the survey answers.

Three things are worth knowing before you write one.

Answer the question that was asked
The response document is organised question by question, and percentages are reported per question. A response that does not engage with a numbered question is much harder for officials to count, and counting is how the document gets written.
Say what you are
Demographic data existed for the 170 survey respondents and not for the 39 email ones, which is why the response document can tell you 25% were in financial services but cannot tell you much about the rest. Self-classification makes your answer usable.
A concrete drafting problem beats a position
Every change traceable to consultees here came from someone identifying a specific provision that would not work in practice — not from support or opposition in general terms.

Responses are published in summary rather than in full: this consultation’s response document lists responding organisations in Annex B but does not reproduce individual submissions, and individuals are excluded from the list unless they asked to be named. If you need your position on the public record verbatim, publishing it yourself is the only reliable route.

UK SRS consultation — wind turbines at dawn over UK farmland, the bottom line on two closed consultations

Both consultations have closed. The Department for Business and Trade finished its half and published UK SRS S1 and S2 for voluntary use, with no effective date in either. The FCA has not finished its half: as at 14 August 2026 there is no policy statement, no change to the UK Listing Rules, and no UK entity under any obligation to report against UK SRS.

The bottom line · Photo: Unsplash / Zac Wolff
Two consultations, not one
DBT consulted on the UK SRS exposure draft standards, 25 June to 17 September 2025. The FCA consulted on who must apply them, 30 January to 20 March 2026. They asked different questions and are in different states.
209 responses, and they changed things
DBT’s figure, for its consultation only. The FCA has published no response count for FCA CP26/5. At least four substantive changes to the standards are traceable to what consultees said.
Six amendments were proposed. Six is not what landed
One was withdrawn, one was replaced by something broader, and three more were added after the consultation closed. Annex A is the authoritative list, and it carries no count.
No effective date, on purpose
Both standards had the ISSB’s 1 January 2024 effective date removed, so that nothing is confused with a future reporting requirement. UK SRS cannot commence on its own.
No policy statement exists
As at 14 August 2026. The FCA’s page still says it aims to publish one in autumn 2026, subject to the final UK SRS, and has not been substantively updated since 5 June 2026.
~600 affected, 515 complying, 89 signposting

The responses

Who answered the UK SRS exposure draft consultation, and how they voted

Every percentage DBT published, in one place, with the number of respondents each is calculated on.

Response rates differ question by question, which matters: a percentage on 184 responses and a percentage on 146 are not directly comparable, and the response document is careful to give both numbers every time. So is this table.

Questions

UK SRS consultation FAQs

The questions people actually search for on this subject, answered from the primary documents rather than from each other.

What is the UK SRS consultation?

It is two separate consultations that are often spoken of as one. The Department for Business and Trade consulted on exposure drafts of UK SRS S1 and S2 from 25 June to 17 September 2025, asking whether to endorse the ISSB’s IFRS S1 and IFRS S2 for UK use and what to amend. The Financial Conduct Authority separately consulted through CP26/5, from 30 January to 20 March 2026, on whether to change the UK Listing Rules so that listed companies must report under UK SRS S2. Both have closed. DBT published its final standards on 25 February 2026; the FCA has published nothing further.

Has the UK SRS consultation closed?

Yes, both of them. The DBT exposure draft consultation closed on 17 September 2025 and its outcome page records it as concluded. FCA CP26/5 closed on 20 March 2026. There is no open UK SRS consultation to respond to as at 14 August 2026, although the government has promised a consultation on Modernising Corporate Reporting which would cover whether private companies must report against UK SRS.

What is FCA CP26/5?

FCA CP26/5 is the Financial Conduct Authority’s consultation paper Aligning listed issuers’ sustainability disclosures with international standards. It proposes replacing the FCA’s existing TCFD-aligned Listing Rules with requirements based on UK SRS S2. It opened on 30 January 2026 and closed on 20 March 2026. The FCA has not published a response count, a summary of responses, or a policy statement.

Has the FCA published a policy statement on UK SRS?

No. As at 14 August 2026 no policy statement responding to CP26/5 has been published. The CP26/5 page still carries the FCA’s original wording — “we will review the feedback and aim to publish a Policy Statement in autumn 2026, subject to the final UK SRS, with the rules coming into force from 1 January 2027” — and that page has not been substantively updated since 5 June 2026.

What did the FCA consultation on UK SRS propose?

That in-scope listed companies disclose climate-related risks and opportunities in accordance with UK SRS S2, applying UK SRS S1 provisions so far as relevant to those disclosures. UK SRS S2 excluding Scope 3 would be mandatory; Scope 3 emissions and sustainability matters beyond climate would be comply or explain. Implementation would be phased, taking effect from 1 January 2027. That summary is DBT’s own, at paragraph 1.15 of its government response.

What is the UK SRS exposure draft?

The UK SRS exposure draft was the consultation version of UK SRS S1 and UK SRS S2, published by DBT on 25 June 2025 alongside marked-up drafts showing the proposed amendments to the ISSB baseline. It proposed six minor amendments for a UK context. The exposure drafts have been superseded by the final standards, published 25 February 2026 — and the final versions differ from the drafts in several respects.

When did the UK SRS exposure draft consultation run?

From 1pm on 25 June 2025 to 11:59pm on 17 September 2025 — twelve weeks. It was published as part of the government’s response to the Mansion House package of November 2024, alongside consultations on transition plans and on the oversight of sustainability assurance providers.

How many responses did the UK SRS consultation receive?

DBT received 209 responses to the exposure draft consultation: 170 through an online survey and 39 emailed directly to the department. 199 were organisations and 10 were individuals. That figure belongs to DBT’s consultation only. The FCA has published no response count for CP26/5, so any page attributing 209 responses to the FCA has confused the two.

Are there six UK amendments to UK SRS?

Six were proposed — DBT’s consultation says “the government proposes 6 minor amendments”, being four from the Technical Advisory Committee and two from the Policy and Implementation Committee. But six is not what landed. One was withdrawn, one was replaced by a broader change, and further amendments were added after the consultation closed. The government publishes no count of the differences in the final standards; Annex A of its response is a paragraph-by-paragraph mapping and is the authoritative answer.

Which proposed amendment was withdrawn?

The proposal to remove the Global Industry Classification Standard (GICS) requirement from UK SRS S2. Respondents who agreed with it largely argued the UK should align with whatever the ISSB decided rather than diverge alone. The ISSB finalised its own amendment in December 2025 on an approach “broadly consistent with the intention behind the UK’s proposed amendment”, so the government incorporated the ISSB change and dropped its own. GICS does not appear in Annex A, because there is no longer a difference to record.

Does UK SRS have an effective date?

No, and that is deliberate. IFRS S1 and IFRS S2 each carry an effective date of 1 January 2024. Both were removed from UK SRS “to avoid any confusion with the introduction of any reporting requirements”. Annex A states the consequence: entities can apply the standards when they choose, unless required by UK law or regulation to apply them from a specific reporting period. The requirement to apply S1 and S2 at the same time survives.

Is UK SRS mandatory?

No. UK SRS S1 and S2 are available for voluntary use by any entity, in whole or in part. No UK entity is under any legal obligation to report against them. The FCA has proposed rules that would make UK SRS S2 mandatory for certain listed companies, but those rules have not been made.

When does UK SRS become mandatory?

There is no date. The frequently quoted 1 January 2027 is the date from which the FCA proposed its Listing Rules changes would come into force — in a consultation that closed in March 2026 and has not been answered. The FCA’s own sentence hedges it twice: it “aims to” publish a policy statement, “subject to the final UK SRS”. Until that policy statement exists, no commencement date exists.

Who is in scope of FCA CP26/5?

CP26/5’s Cost Benefit Analysis puts around 600 listed companies in scope. Of those, 515 — in UK Listing Rules categories 6 (commercial companies), 16 (non-equity and non-voting equity shares) and 22 (transition) — “will be required to comply”. The remaining 89, in categories 14 (secondary listing) and 15 (depositary receipts), would instead disclose which climate or sustainability requirements apply in their primary listing location or place of incorporation. Quoting 515 as the scope leaves the 89 out.

What is the difference between the DBT consultation and the FCA consultation?

They asked different questions. DBT asked whether these are the right standards — whether to endorse IFRS S1 and S2 for UK use and what to amend. It finished, and published UK SRS S1 and S2 on 25 February 2026. The FCA asked who must use them — whether to change the UK Listing Rules so listed companies report under UK SRS S2. It has not finished. Confusing the two is why the “209 responses” figure is so often misattributed.

Is UK SRS still happening?

Yes, in the sense that matters: the standards exist and are final. UK SRS S1 and UK SRS S2 were published on 25 February 2026 and any entity may use them today. What has not happened is mandation — the FCA’s proposals to require listed companies to use them are still unanswered, and no route to private companies has been consulted on.

What is British SRS?

It is an informal name for the same thing: the UK Sustainability Reporting Standards, UK SRS S1 and UK SRS S2, published by the Department for Business and Trade on 25 February 2026. They are the UK-endorsed versions of the ISSB’s IFRS S1 and IFRS S2, with a small number of UK-specific amendments recorded in Annex A of the government’s consultation response.

Can I use UK SRS voluntarily?

Yes, and the government has been unusually expansive about it. The standards are “available for any entity to use, in whole or in part, as they see fit”. Because there is no effective date, there is nothing to be early or late for. And because the time limits were removed from the climate-only and Scope 3 reliefs, a voluntary reporter may use those reliefs indefinitely.

Can I say I comply with UK SRS if I use a relief?

It depends which relief, and the rule is not symmetrical. Under UK SRS S1 paragraph 73A, an entity using the climate-only relief at paragraph E3 may not assert compliance with UK SRS S1 and must disclose its use of the relief. But using any one or more of the three reliefs — S1 E3, S2 C3 on GHG Protocol alternatives, S2 C4 on Scope 3 — does not prevent an entity asserting compliance with UK SRS S2, provided the reliefs used are disclosed.

What is UK SRS S2 paragraph B59A?

A new paragraph with no IFRS S2 counterpart. Where an entity determines it is impracticable to reliably estimate financed emissions for the same reporting period as its related financial statements, B59A requires it to explain why it has not disclosed in line with paragraph B59. It was added after the consultation, following fresh Technical Advisory Committee advice of 26 January 2026, because responses to questions 2 and 3 argued the original timing requirement was not practicable.

Which reporting periods need comparative information under UK SRS S1?

No comparatives are required in the first annual reporting period at all. Climate comparatives are required from the second period, as under IFRS S1. The change is to paragraph E4(b): comparatives for wider sustainability matters are required in the second annual reporting period in which the entity no longer applies the paragraph E3 climate-only relief — not the second period of reporting. Since that relief lost its own time limit, the clock can start years after first application.

Did the UK change the rules on SASB standards?

Yes. IFRS S1 paragraphs 55(a) and 58(a) say an entity “shall refer to and consider” the applicability of the SASB Standards; UK SRS S1 says “may”. The same change was made at UK SRS S2 paragraphs 12, 23 and 32 for the Industry-based Guidance on Implementing IFRS S2. 70% of respondents (122 of 175) agreed. Note that paragraphs 37 and B65(d) of UK SRS S2 still say “shall” — they refer to industry-based metrics in general, not to that guidance document.

What happens if the FCA policy statement is late?

Nothing changes for anybody. The existing TCFD-aligned Listing Rules continue to apply to listed companies, UK SRS remains voluntary, and no obligation arises. The practical consequence of a slip is to the proposed 1 January 2027 commencement, which becomes progressively harder to justify on notice grounds the later a policy statement appears. A consultation can also end without rules being made at all.

Where can I read the government response to the UK SRS consultation?

On GOV.UK, attached to the consultation outcome page for Exposure drafts: UK Sustainability Reporting Standards, in both a web version and a 42-page PDF, published 25 February 2026. Its Annex A is the paragraph-by-paragraph mapping of every difference between IFRS S1/S2 and UK SRS S1/S2, and its Annex B lists the responding organisations.

Glossary

The UK SRS consultation vocabulary, defined

Fourteen terms that appear on this page and are routinely used loosely elsewhere.

UK SRS
UK Sustainability Reporting Standards. Two documents, UK SRS S1 and UK SRS S2, published 25 February 2026 and available for voluntary use by any entity, in whole or in part.
Exposure draft
The consultation version of a standard, published for comment before it is finalised. The UK SRS exposure drafts were published 25 June 2025 and are superseded by the final standards.
Endorsement
The process by which the UK decides to adopt an international standard for domestic use, with or without amendment. UK SRS is the product of endorsing IFRS S1 and IFRS S2.
TAC
The UK Sustainability Disclosure Technical Advisory Committee, which assesses standards against the endorsement criteria. It recommended four of the six proposed amendments.
PIC
The UK Sustainability Disclosure Policy and Implementation Committee, which advises on policy and implementation. It recommended the other two, and raised the reliefs question after the consultation closed.
CP26/5
The FCA’s consultation paper on aligning listed issuers’ sustainability disclosures with international standards. Closed 20 March 2026; unanswered.
Policy statement
The document in which the FCA confirms, modifies or abandons what it consulted on, and makes the final rules. None has been published in response to CP26/5.
Comply or explain
An obligation to do something or publish an explanation of why you have not. CP26/5 proposes it for Scope 3 emissions and for sustainability matters beyond climate.
Transitional relief
A provision letting an entity omit or defer something in early reporting periods. UK SRS has three: the climate-only relief (S1 E3), the Scope 3 relief (S2 C4) and the GHG-Protocol-alternative relief (S2 C3).
Climate-only relief
UK SRS S1 paragraph E3. Lets an entity report on climate alone. Unlike the others it costs the entity its UK SRS S1 compliance statement, under paragraph 73A.
Statement of compliance
An entity’s assertion that it has applied a standard. UK SRS S1 paragraphs 73A and 73B govern when one may be made and who may override that.
Effective date
The date from which a standard applies. IFRS S1 and IFRS S2 have one (1 January 2024); UK SRS S1 and UK SRS S2 deliberately have none.
UKLR
The UK Listing Rules, which replaced the previous premium and standard listing segments on 29 July 2024. CP26/5 works through categories 6, 14, 15, 16 and 22.
MCR
Modernising Corporate Reporting, the DBT programme announced in October 2025 which will consider whether the Companies Act should require private entities to report against UK SRS.
