SECR legislation: an instrument that spent itself in a day
SI 2018/1155 is the only SECR amendment there has ever been — and it is not itself a place to look for SECR's rules. It is an amending instrument, made under a general Companies Act power, that inserted text into two older statutory instruments and then had nothing left to do. The scope tests and the disclosure list live in what it left behind, not in the instrument itself.
Where SECR gets its authority
SECR is secondary legislation with no Act of its own — it borrows a general power written for directors' reports, not a power drafted for an energy and carbon regime.
1 The Companies (Directors’ Report) and Limited Liability Partnerships (Energy and Carbon Report) Regulations 2018 (SI 2018/1155) were made on 6 November 2018 and, by regulation 2(2), have effect for financial years beginning on or after 1 April 2019.
The preamble states the powers relied on in full: 2“sections 416(4) and 1292(1) of the Companies Act 2006 and sections 15 and 17 of the Limited Liability Partnerships Act 2000”.
Section 416(4) is the whole hook. Read on legislation.gov.uk, it says: “The Secretary of State may make provision by regulations as to other matters that must be disclosed in a directors’ report,” adding “without prejudice to the generality of this power, the regulations may make any such provision as was formerly made by Schedule 7 to the Companies Act 1985.”
That is a general power to prescribe directors’-report contents, not a power drafted for an energy-and-carbon regime. Contrast ESOS: its enabling powersare Part 11 of the Energy Act 2023 — sections written specifically to create and amend an energy savings scheme. SECR has never had an equivalent Act. It exists because a directors’ report can be told to contain more, and in 2018 the Secretary of State used that power to tell it to contain energy and carbon data.
Companies Act 2006, section 416(4)
The entire statutory hook for SECR.
It is a general power to add matters to a directors' report, not a bespoke energy-reporting power — and the section itself points back to the old Companies Act 1985 Schedule 7 regime as the kind of thing it is meant to allow.
What SI 2018/1155 actually did
Three regulations, three insertions or amendments into two older instruments — and nothing left in SI 2018/1155 itself once they took effect.
SI 2018/1155 is short. Its substance is three regulations, each doing the same kind of thing to a different limb of the audience: amending or inserting text into an existing statutory instrument that was not otherwise about energy or carbon at all.
Regulation 6 — amends Part 7 of Schedule 7 to SI 2008/410
The quoted-company limb.
This is an amendment to an existing Part, not an insertion — the quoted-company GHG reporting duty already existed and reg 6 extended it to cover energy use and an intensity ratio.
Regulation 7 — inserts Part 7A into Schedule 7 to SI 2008/410
The large-unquoted-company limb, and the one everyone means by "SECR" when they picture a scope test and a disclosure list.
Part 7A did not exist before this regulation; reg 7 created it whole.
Regulation 10 — inserts Part 5A and regulation 12B into SI 2008/1911
The large-LLP limb, applying modified Companies Act 2006 sections 415 and 416 to LLPs via the Limited Liability Partnerships (Accounts and Audit) (Application of Companies Act 2006) Regulations 2008.
On the face of legislation.gov.uk, the only amendment note against Part 7A reads: “F1 Sch. 7 Pt. 7A inserted (1.4.2019) by S.I. 2018/1155, regs. 2, 7.” Part 7A has never been amended since. The full scope tests, the disclosure list and the exemptions that sit inside it are the subject of SECR requirements, not this page — what matters here is that they live in that Part, and in no other document.
Affirmative resolution, not negative
Both Houses approved a draft of SI 2018/1155 before it could be made — the opposite procedure from a negative-resolution instrument that Parliament can only annul after the fact.
The preamble to SI 2018/1155 states, verbatim: 3“In accordance with sections 473(3) and 1290 of the Companies Act 2006 and section 17(6) of the Limited Liability Partnerships Act 2000, a draft of this instrument has been laid before Parliament and approved by a resolution of each House of Parliament.”
Section 1290 of the Companies Act 2006is headed “Regulations and orders: affirmative resolution procedure” and reads: “Where regulations or orders under this Act are subject to ‘affirmative resolution procedure’ the regulations or order must not be made unless a draft of the statutory instrument containing them has been laid before Parliament and approved by a resolution of each House of Parliament.”
That sequence — draft laid, both Houses approve, only then made — is the affirmative procedure. It is not the negative procedure, under which an instrument is made first and laid afterwards, taking effect unless either House votes within a set period to annul it. SI 2018/1155 is affirmative-resolution, and its own preamble says so in as many words.
One amendment, and a 2024 uplift that missed it
Part 7A has been amended exactly once — by its own insertion. The 2024 Companies Act size-limit rise had no mechanism to reach it, and did not.
Companies Act 2006 2section 416 carries note C3, recording that sections 415–416 are applied with modifications by SI 2008/1911 regulation 12B, as inserted (1.4.2019) by SI 2018/1155 regs 2 and 10, and as amended (6.4.2022) by SI 2022/46 — a separate climate-related financial disclosure instrument, not a SECR amendment (see §05 below). That is the only amendment note that touches SECR’s LLP limb at all, and it modifies the climate-disclosure application sitting alongside SECR in the same regulation, not Part 7A’s own text.
The instrument that did try to move company-size thresholds is 4SI 2024/1303, raising Companies Act size limits for periods beginning on or after 6 April 2025. Its regulation 5(3) states, verbatim: “In Schedule 7 (matters to be dealt with in directors’ report), omit paragraphs 6 and 7 and Parts 3 and 4.” Parts 3 and 4 only — Part 7A is not named.
Paragraph 20B(2) of Part 7A hardcodes £36 million, £18 million and 250 employees in the instrument’s own table, with no cross-reference to Companies Act 2006 section 465. An uplift to section 465 has nothing to travel along to reach Part 7A.
Static since 1 April 2019, untouched by the 2025 Companies Act uplift
Because Part 7A's own thresholds are hardcoded rather than cross-referenced to Companies Act 2006 s.465, the April 2025 rise in the Companies Act's own size bands passed Part 7A by entirely.
The practical consequence: since 6 April 2025 a company can be medium-sized for its accounts and still in scope for SECR on the same figures.
DESNZ's 2026 post-implementation review restates the same figures, defining SECR scope as turnover of £36 million or more, balance sheet total of £18 million or more, and/or 250 or more employees.
What SECR legislation is not
Two mix-ups recur often enough to be worth naming directly.
Not the 2022 climate-related financial disclosure regulations
SI 2022/31 (companies) and SI 2022/46 (LLPs) are the climate-related financial disclosure regime — a different set of provisions, with different scope, made for a different purpose.
"SECR’s latest version is 2022" is wrong on the facts: SECR’s last and only amendment was made in 2018 and took effect 1 April 2019.
CA 2006 s.416 does carry a note recording that SI 2008/1911 reg 12B was amended (6.4.2022) by SI 2022/46 — but that note is about the climate-disclosure modification sitting alongside SECR in the same regulation, not about SECR’s own Part 7A text, which that amendment does not touch.
Not enforced by the Environment Agency
SECR is a directors’ report disclosure.
It is policed through the FRC’s Conduct Committee and the accounts-filing regime at Companies House — not by an ESOS-style scheme administrator.
There is no SECR compliance notice, enforcement notice or civil penalty regime comparable to Part 7 and 8 of the ESOS Regulations 2014, because SECR was never built as a standalone enforced scheme.
Both errors share a root cause: treating SECR as a live, regularly-updated scheme with its own regulator, the way ESOS is — see where ESOS gets its authorityfor the contrast. SECR is neither. It is a single insertion into the directors’ report disclosure duty, made once in 2018, reviewed and enforced through the ordinary Companies Act accounts machinery ever since.
What is the SECR legislation?
There is no single SECR Act.
SECR is a directors'-report disclosure inserted by the Companies (Directors' Report) and Limited Liability Partnerships (Energy and Carbon Report) Regulations 2018 (SI 2018/1155), made 6 November 2018 and in force for financial years beginning on or after 1 April 2019.
SI 2018/1155 is itself a spent amending instrument — it inserted text into Schedule 7 to SI 2008/410 and into SI 2008/1911, and that inserted text, not SI 2018/1155, is what a company reports against today.
What power was SECR made under?
Section 416(4) of the Companies Act 2006, which lets the Secretary of State make regulations "as to other matters that must be disclosed in a directors' report," together with section 1292(1) of the same Act and sections 15 and 17 of the Limited Liability Partnerships Act 2000.
SECR has no Act written specifically for it — contrast ESOS, which has Part 11 of the Energy Act 2023.
Was SI 2018/1155 made by affirmative or negative resolution?
Affirmative.
The preamble states that a draft of the instrument was laid before Parliament and approved by a resolution of each House before it was made, in accordance with sections 473(3) and 1290 of the Companies Act 2006 and section 17(6) of the Limited Liability Partnerships Act 2000.
Section 1290 is headed "Regulations and orders: affirmative resolution procedure" and requires exactly that sequence — approval before making.
A negative-resolution instrument, by contrast, is made first and laid afterwards, subject only to annulment.
This site's own canon described SECR as negative-resolution until 24 August 2026; that was incorrect.
Where does the operative text of SECR actually sit today?
In Part 7A of Schedule 7 to the Large and Medium-sized Companies and Groups (Accounts and Reports) Regulations 2008 (SI 2008/410), for companies, and in Part 5A / regulation 12B of the Limited Liability Partnerships (Accounts and Audit) (Application of Companies Act 2006) Regulations 2008 (SI 2008/1911), for LLPs.
Both were inserted by SI 2018/1155 regs 7 and 10 respectively.
On legislation.gov.uk, the only amendment note against Part 7A is its own insertion — it has never been amended since.
Did the 2024 Companies Act size-limit uplift change SECR?
No.
SI 2024/1303 raised the Companies Act 2006 size thresholds for periods beginning on or after 6 April 2025, but regulation 5(3) of that instrument omits only paragraphs 6 and 7 and Parts 3 and 4 of Schedule 7 — Part 7A is not named and was not touched.
Paragraph 20B(2) hardcodes £36 million / £18 million / 250 employees in SI 2018/1155's own table, with no cross-reference to Companies Act 2006 section 465, so the 2025 uplift to section 465 has no mechanism by which to reach it.
The practical result: since 6 April 2025 a company can be medium-sized for its own accounts under the new Companies Act bands and still be in scope for SECR on the same figures.
Is SECR the same as the 2022 climate-related financial disclosure regulations?
No.
SI 2022/31 (companies) and SI 2022/46 (LLPs) are a separate climate-related financial disclosure regime with its own scope.
SECR's only amendment remains SI 2018/1155, in force 1 April 2019 — nothing in the 2022 instruments touches Part 7A of Schedule 7 to SI 2008/410.
Who enforces SECR legislation?
Not the Environment Agency.
SECR sits inside the directors' report and is subject to the same review and enforcement machinery as the rest of a company's annual report and accounts — the FRC's Conduct Committee and the Companies Act filing regime — rather than any scheme-specific regulator or civil penalty scale.
