CSRD · readiness, check by check

CSRD readiness checklist: every check, and the rule behind it

A CSRD readiness checklist should run in six phases — scope, version, materiality, disclosures, value chain, and controls with assurance — and every line should name its rule.

This one is keyed to Directive 2013/34/EU as amended by Omnibus I and to the revised ESRS in Delegated Regulation (EU) 2026/1563, as at 11 October 2026.

It is not a datapoint list, because the body that writes the datapoint list says its list must not be used as one.

How the checklist runs

Six phases of CSRD readiness, in the order the rules impose

The order matters, because each phase depends on the answer to the one before.

Scope decides whether the rest applies at all, and the version decides which paragraph numbers the rest of the work cites.

Read how to use the checklist

Each table below gives the check, what it means and the provision it comes from.

Treat a check as done only when you can point to the evidence for it, because the assurance opinion covers the process as well as the result.

The checklist describes what the rules require; it sets no timetable, and the readiness plan further down is an illustration.

The rules themselves are summarised on the CSRD explained and the standards on the ESRS page.

Phase 1 · scope

Are you in scope? The FY2027 test has two limbs

From financial years beginning on or after 1 January 2027 the CSRD reaches undertakings that exceed both €450 million of net turnover and an average of 1,000 employees.

One limb is not enough, and a figure exactly at the threshold does not exceed it.

Wave one reported for financial years 2024 to 2026, and the stop-the-clock directive moved the later waves to 2027 and 2028 before Omnibus I replaced them with the single test.

The figures can be run through the scope checker on CSRD thresholds, and the history of the dates is on the CSRD timeline.

Phase 2 · version

From financial years beginning on or after 1 January 2027 the revised ESRS apply with no choice.

Phase 3 · double materiality

The assessment that decides what you report

The double materiality assessment converts the twelve standards into the handful a given undertaking reports.

Either lens is enough: impacts can be material “irrespective of whether they are financially material” (ESRS 1 ¶35).

The method in full is on running a double materiality assessment, a working register on the assessment template, and the threshold question on materiality thresholds.

EFRAG’s implementation guidance was written for the 2023 ESRS and is non-authoritative; as at 11 October 2026 none is listed for the revised set.

Route

Top-down or bottom-up, topic by topic.

Phase 4 · disclosures

ESRS 2 first, the rest only if material

Once the assessment is done, the disclosure checks follow from it: ESRS 2, whose disclosures are likely to be material for every undertaking, then the material topical standards, and only the material sub-topics within them.

Over-reporting is now a defect, because information that is not material shall not be disclosed.

Climate is the standard most undertakings test first: ESRS E1, requirement by requirement, sets out the eleven disclosure requirements, including location- and market-based Scope 2 and significant Scope 3 categories.

Own workforce is the other common candidate, and ESRS S1 in full lists its sixteen requirements and the first-year omissions.

Anticipated financial effects can be omitted in early years, but the relief does not reach ESRS E1-11 paragraphs 39(a)(b) and 40(a)(b).

What gets reportedExplore

Module 01 / 04

ESRS 2

Likely to give material information for every undertaking.

The datapoint list

The one document that is not a CSRD checklist

The most common shortcut is to treat EFRAG’s list of datapoints as the checklist.

EFRAG’s own explanatory note says the list “must not be used as a checklist” and should be used “only in conjunction with the exercise of judgement underpinning materiality considerations”.

Read what the list is for

The note also says the revised ESRS “have no mandatory datapoints that are to be reported irrespective of materiality assessment” (¶68).

Its draft count is 292 “shall” datapoints, excluding the policy, action, target and metric datapoints and six technical ones, and every one is subject to materiality.

Read that way, it helps check coverage once the materiality judgements are made, and EFRAG expects the final version by the end of 2026; ESRS datapoints explains the count and what each figure measures.

EFRAG explanatory note, ¶1

Phase 5 · value chain

What you may ask suppliers for, and what they may decline

The revised ESRS 1 lets an undertaking assess its value chain using “average regional data, sector data or generally available information” (¶33).

And Omnibus I limits what it may require from suppliers with an average of 1,000 employees or fewer in the preceding financial year.

Read the value-chain checks

Phase 6 · controls and assurance

The last phase makes the first five provable: controls, an evidence trail and an assurance provider allowed to give the opinion.

The opinion is limited assurance, and it covers the process carried out to identify the information reported as well as the result.

GOV-4

Internal controls over sustainability reporting are a disclosure.

UK groups

CSRD readiness for a UK group

No UK law asks a UK company to be CSRD-ready.

A UK group meets the CSRD through an EU subsidiary, an EU listing, Article 40a from FY2028, or as a supplier receiving requests.

Read the UK angle

The routes for UK groups are set out under CSRD reporting for UK groups.

UK SRS applies single (financial) materiality, so a group reporting under both can start its UK work from the financially material subset of its ESRS assessment; how the CSRD and UK SRS compare covers the overlap.

How the scope changed under Omnibus I is on the CSRD after Omnibus I.

Frequently asked

Questions people ask

What should a CSRD readiness checklist cover?

Six things in order: whether the undertaking is in scope and from when; which version of the ESRS it applies; its double materiality assessment; the disclosures that follow, including the phase-ins; its value-chain information; and its data, controls and assurance.

Each check should name the provision it comes from, so that the checklist can be tested rather than trusted.

Who is in scope of the CSRD from FY2027?

Undertakings that exceed both a net turnover of €450 million and an average of 1,000 employees, for financial years beginning on or after 1 January 2027, under Article 19a(1) of the Accounting Directive as amended by Omnibus I; parents test the group on a consolidated basis under Article 29a(1).

Both limbs must be exceeded.

Non-EU groups are reached separately under Article 40a from financial year 2028.

Can I use EFRAG’s datapoint list as a CSRD checklist?

No. EFRAG’s explanatory note to its 2026 Draft List of Datapoints says the list “must not be used as a checklist” and should be used “only in conjunction with the exercise of judgement underpinning materiality considerations”.

It lists every datapoint the ESRS define, and the note says none is reported irrespective of materiality.

Which version of the ESRS applies to my first report?

For a financial year starting in 2026 there are three choices: the 2023 ESRS as amended by Delegated Regulation (EU) 2025/1416; those standards with eight reliefs from the revised set; or the revised ESRS in full.

The undertaking must state which it used.

From financial years beginning on or after 1 January 2027 the revised ESRS apply.

Is a double materiality assessment the first step?

It comes after scope and version.

Once those are settled, the assessment decides which topical standards and sub-topics are reported; ESRS 2’s disclosures are “likely to result in material information for all undertakings” (ESRS 1 AR 12), and information that is not material shall not be disclosed, apart from supplementary information under section 8.2 of ESRS 1.

Do I have to report on climate?

Only if climate change relates to material impacts, risks or opportunities.

ESRS E1 applies on that condition.

If climate is judged not material, ESRS 2 IRO-2 requires the basis for that conclusion.

What does the CSRD assurance check involve?

A limited assurance opinion covers the sustainability reporting, its compliance with the ESRS, the process carried out to identify the information reported, and the Taxonomy Article 8 disclosures.

The reasonable-assurance path was deleted by Omnibus I, and the Commission must adopt limited-assurance standards by 1 July 2027.

Is XBRL tagging part of CSRD readiness?

Not yet as an obligation.

EFRAG says digital tagging of ESRS disclosures is not yet mandatory because the framework is still to be established by ESMA and the Commission.

Its draft taxonomy for the revised ESRS is out for consultation until 11 November 2026.

What phase-ins can a first-time reporter use?

The revised ESRS 1 ¶¶125–127 allow, among others, omission of anticipated financial effects for early years, with a carve-out for parts of ESRS E1-11, and omission of several ESRS S1 datapoints in the first year of reporting for undertakings outside wave one.

ESRS 1 ¶124 removes comparatives in the first year in specified cases.

Does a UK company need to be CSRD-ready?

Only if the CSRD reaches it: through an EU subsidiary or parent above the thresholds, an EU listing, or, from financial year 2028, Article 40a on its EU turnover.

UK law asks for none of this, and UK SRS uses single (financial) materiality.

Can our auditor help us prepare the sustainability statement?

For a public-interest entity, preparing sustainability reporting is a prohibited non-audit service for the statutory auditor under Article 5(1)(c) of Regulation (EU) No 537/2014.

Who may assure, and what other help is allowed, depends on national law and the firm’s independence rules.

Do suppliers have to answer our CSRD questionnaire?

No legal obligation arises from your CSRD reporting.

The value-chain cap protects undertakings with an average of 1,000 employees or fewer in the preceding financial year from requests beyond the voluntary standard’s capped datapoints, and the Commission says the cap imposes no obligation on companies in the value chain.

When must Member States transpose Omnibus I?

By 19 March 2027 for Articles 1 to 3 of Directive (EU) 2026/470.

National law then sets details such as assurance-provider options, so a readiness plan should be checked against the transposing law of the Member State concerned.

Is there official EFRAG guidance for the revised ESRS?

Not as at 11 October 2026.

EFRAG’s implementation guidance IG 1–3 relates to the 2023 ESRS and is non-authoritative; EFRAG’s guidance page lists none for the revised set.
