FCA final rules · UK SRS on a comply-or-explain basis from 2027
The FCA’s UK SRS rules: what the annual report must contain
The FCA’s UK SRS rules are a handful of new limbs in UKLR 6.6.6R, made on 24 September 2026 and published in PS26/19 on 30 September 2026.
They ask each listed company in scope to report against UK SRS S1 and S2 or explain the gap, and to make three short statements: where the disclosures are, whether they were assured, and whether it has a transition plan.
This page reads the rule text limb by limb, with the FCA’s draft guidance on explaining beside it.
From consultation to force
How the rule was made, and what is still to come
The rule began as CP26/5, published on 30 January 2026 and closed on 20 March 2026 (consultation page).
It was made by the FCA Board on 24 September 2026 and published on 30 September as PS26/19, whose Appendix 1 is the instrument itself: the UK Listing Rules (Sustainability Reporting Standards Disclosure) Instrument 2026.
The instrument carries no FCA number in the Policy Statement, and none is given here.
Listing rules are made under Part 6 of the Financial Services and Markets Act 2000, including section 73A.
The guidance is not finished: Primary Market Bulletin 66 consults on draft Technical Note 803.1, with comments to primarymarketbulletin@fca.org.uk by 28 October 2026, and the FCA aims to finalise it before the rules come into force.
What each step settled is set out on the UK SRS timeline, and what the consultation proposed against what was made on the UK SRS consultations.

The rule text
UKLR 6.6.6R as made, limb by limb
The rule for commercial companies.
UKLR 14, 15, 16 and 22 carry the same limbs in their own chapters.
Quotation marks show the made text.
| Limb | What the annual financial report must contain | Read with |
|---|---|---|
| (7A)(a) | “climate-related financial disclosures prepared in accordance with UK SRS S2” | UK SRS S2; UKLR 6.6.6A G |
| (7A)(b) | If not, or only in part: (i) “a summary of the UK SRS S2 disclosure requirements that have not been met”; (ii) the reasons; (iii) “any steps it is taking or plans to take” | No timeframe asked for |
| (7B)(a) | “sustainability-related financial disclosures prepared in accordance with UK SRS S1” beyond the climate ones | UK SRS S1 |
| (7B)(b) | If risks or opportunities “of the kind described in paragraph 3 of UK SRS S1” are identified but not disclosed: those risks or opportunities, and the reasons | Explain by risk, not by requirement |
| (8)(c) | Where the disclosures can be found; cross-reference allowed under UK SRS S1 ¶¶B45–B47 | Location |
| (8)(d) | Whether third-party assurance was obtained and, if so, the provider, what was assured and to what level, the standards used, and where the report is | Assurance not required |
| (8)(e) | Whether a climate-related transition plan has been published and where; if not, why not | Not for UKLR 14 and 15 |
| 6.6.6A G | A reminder to apply UK SRS S1 ¶¶10–24, 31, 49, 50, 52, 53 and 60–71 with the climate disclosures | Guidance, not rule |
| TP 16 | Transitional provisions: the reliefs and the choice for periods beginning before 1 January 2027 | PS26/19 ¶¶3.14–3.24 |
The same S2 limb appears as UKLR 14.3.24R(4), 16.3.23R(4) and 22.2.24R(4), and depositary receipts reach it through UKLR 15.3.1R(3) (draft TN 803.1).
The current text of the commercial-companies rule, with its future version from 1 January 2027 flagged, is on the Handbook at UKLR 6.6.
The explain limb for UK SRS S1 refers to paragraph 3 of UK SRS S1, which describes the sustainability-related risks and opportunities that could reasonably be expected to affect an entity’s prospects.
Where no such risks or opportunities are identified, the draft guidance expects a statement disclosing that fact.
The standards themselves are on UK SRS S2 and UK SRS S1, published by the government on GOV.UK.
Who it reaches
Five listing categories in, six left out
The rule reaches companies on the Official List in five categories (PS26/19 ¶3.6).
For investment vehicles, the FCA says “the best way to introduce requirements … is through obligations on the asset manager”, and for debt and similar securities it does “not consider it to be proportionate or effective to extend requirements” (¶3.7).
International companies with a secondary listing and depositary-receipt issuers were brought onto the same basis as domestic companies; the FCA counted 89 of them in its consultation-stage analysis (¶4.35).
Those issuers “may therefore rely on home-jurisdiction reporting to reduce duplication”, and explain where UK SRS requirements are not met in full.
The Policy Statement gives no total; CP26/5 estimated that around 600 listed companies would be affected, and that remains the consultation’s estimate.
AIM companies, private companies and LLPs are not reached at all; the standards stay voluntary for them, and the entity-level tests are on UK SRS scope.
| In scope (¶3.6) | Excluded (¶3.7) |
|---|---|
| UKLR 6 — commercial companies | UKLR 11 — closed-ended investment funds |
| UKLR 14 — secondary listing | UKLR 12 — open-ended investment companies |
| UKLR 15 — depositary receipts | UKLR 13 — shell companies |
| UKLR 16 — non-equity and non-voting equity shares | UKLR 17 — debt and debt-like securities |
| UKLR 22 — transition | UKLR 18 — securitised derivatives |
| UKLR 19 — warrants, options and other securities |
Comply, or explain
What complying and explaining each ask for
The FCA’s case for the basis is at PS26/19 ¶1.3: where a company does not provide financially material information in line with UK SRS, “a proportionate explanation of their reasoning and judgement can itself provide useful information to investors”.
Its draft guidance, Technical Note 803.1, sets out what it expects when a company complies and when it explains, with illustrative examples in its annexes.
An explanation may point to the headings or paragraphs of the standard that have not been met, rather than walking through them one by one.
The draft describes a good explanation as clear, concise and cogent, and specific to the issuer.
The draft also notes that the listing rules require no separate statement of compliance, and that a company explaining a gap cannot claim unreserved compliance with that standard.
PMB 66 adds two reminders: Listing Principle 1 (UKLR 2.2.1R) on systems and controls, and DTR 4.1.8R on principal risks — a company that explains should consider how climate or sustainability risks among its principal risks are otherwise reflected in its report.
The drafting of the full disclosures is on UK SRS S2; how the explain limbs play out in a first report is on the UK SRS deadline.
An explanation “can be a short, proportionate explanation.
However, the explanation should not omit material information.”
“We do not require issuers to include an expected timeframe”.
“Our rules do not require an explanation for each requirement of the UK SRS that has not been met.”
The reliefs
Two reliefs, one statement, and a choice for early adopters
Initial application is the start of the first annual reporting period beginning on or after 1 January 2027 but before 1 January 2028 (¶3.18).
A company using either relief states that it is doing so in its annual financial report, and “no further explanation … is required during the relief period”, because using a relief “does not engage our ‘explain’ rules” (¶3.20).
It must still make the location, assurance and transition-plan statements while a relief runs.
The Scope 3 relief in UK SRS S2 ¶C4 is untimed in the standard; the FCA gives it its one-year limit at UKLR TP 16.17R(2).
For a period beginning before 1 January 2027, a company chooses between the TCFD-aligned rules in force immediately before that date and early adoption of the new ones; early adopters “can use the same transitional reliefs” (¶3.19), which reverses the consultation’s proposal.
The reliefs as dates, by the year a company’s period begins, are on the UK SRS deadline.
| Relief | Length | What the company says |
|---|---|---|
| Scope 3, under UK SRS S2 | 1 year from initial application | That it is using the relief |
| Non-climate matters, under UK SRS S1 | 2 years from initial application | That it is using the relief |
| GHG measurement method | 1 year, if used immediately before | Its use, beside the compliance statement (UK SRS S2 ¶C5) |
What it replaces
The TCFD-aligned rule it replaces, and the guidance going with it
The new limbs take the place of the TCFD-aligned disclosure rule for listed companies, which UKLR 6.6.6R(8) carried until now.
Limb (8) is rewritten rather than deleted: it now holds the location, assurance and transition-plan statements (Appendix 1).
The TCFD technical note, TN 802.3, is proposed for deletion and TN 801.4 for update, both in PMB 66; TN 802.3 stays live guidance on the old rules until then.
A separate instrument, FCA 2026/59, in force since 25 September 2026, replaced product-level TCFD reporting by asset managers and asset owners (Handbook Notice 144); it is not the listed-company rule.
The FCA says it will keep the case for mandatory sustainability assurance under review; ISSA (UK) 5000 is effective for periods beginning on or after 15 December 2026 for engagements that are obtained.
The FCA estimates a net present value of £174.10m for the final rules over ten years (PS26/19 ¶4.28), and will supervise alongside the FRC, with updated information on its approach in the second half of 2027.
The ISSB standards the new rules point at, through UK SRS, are on the IFRS Foundation’s navigator.
“These rules will replace the existing TCFD aligned disclosures.
TCFD was set up in 2015 but disbanded in 2023.”
The FCA’s own list
Nine preparation steps, in the FCA’s words
PMB 66 closes its sustainability section with the steps the FCA “encourage[s] listed companies” to take before 1 January 2027.
They are the regulator’s, not ours.
| Step | As PMB 66 puts it |
|---|---|
| 1 | Understand and engage with the new requirements, including the proposed Technical Note |
| 2 | Identify financially material sustainability and climate-related risks and opportunities |
| 3 | Review governance arrangements |
| 4 | Ensure sustainability and climate-related risks and opportunities are integrated within corporate strategy |
| 5 | Assess the resilience of their business model and strategy |
| 6 | Develop the data, metrics and targets needed to support UK SRS disclosures |
| 7 | Establish internal controls and review processes |
| 8 | Build organisational capabilities and provide training across relevant functions |
| 9 | Engage with investors to understand their disclosure expectations |
Contemporary commentary on the consultation stage, written when mandatory UK SRS S2 was still proposed, includes KPMG’s briefing on CP26/5 and Addleshaw Goddard’s note on the consultation; both describe the proposal, not the final rules.

Frequently asked
The FCA and UK SRS: the questions asked
What are the FCA’s UK SRS rules?
The UK Listing Rules (Sustainability Reporting Standards Disclosure) Instrument 2026, made by the FCA Board on 24 September 2026 and published in PS26/19 on 30 September 2026.
It amends UKLR 6.6.6R and the equivalent rules for other listing categories so that listed companies report against UK SRS S1 and S2 on a comply-or-explain basis for accounting periods beginning on or after 1 January 2027.
Is UK SRS mandatory for listed companies?
No. Under UKLR 6.6.6R(7A) and (7B) a listed company either makes disclosures in accordance with UK SRS or states which requirements it has not met, why, and what it plans to do.
CP26/5 proposed mandatory UK SRS S2; PS26/19 adopted comply or explain across all of UK SRS.
Which companies do the FCA’s UK SRS rules apply to?
Companies listed in five UK Listing Rules categories: UKLR 6 (commercial companies), 14 (international commercial companies secondary listing), 15 (depositary receipts), 16 (non-equity and non-voting equity shares) and 22 (transition).
Funds, shell companies and debt, securitised derivative and miscellaneous securities are excluded.
The FCA gives no company count; CP26/5 estimated around 600 would be affected.
What must an explanation contain?
For UK SRS S2: a summary of the requirements not met, the reasons, and any steps the company is taking or plans to take.
For UK SRS S1: the relevant risks or opportunities it has not disclosed, and the reasons.
The FCA’s draft Technical Note 803.1, open for comment until 28 October 2026, says an explanation can be short and proportionate but should not omit material information, and need not give a timeframe.
Do the FCA rules require assurance of UK SRS disclosures?
No. UKLR 6.6.6R(8)(d) requires a statement of whether third-party assurance was obtained and, if it was, the provider, what was assured and to what level, the assurance standards used, and where the assurance report can be found.
The FCA says it will keep the case for mandatory assurance under review.
Do listed companies have to publish a transition plan?
No. UKLR 6.6.6R(8)(e) requires a statement of whether the company has published a climate-related transition plan and where, or why it has not.
The FCA says it is not requiring listed companies to produce transition plans.
The statement does not apply to UKLR 14 and 15.
Do the new rules replace the TCFD-aligned listing rules?
Yes.
PS26/19 ¶1.10 says the rules will replace the existing TCFD-aligned disclosures.
The TCFD-aligned rules still govern accounting periods beginning before 1 January 2027, unless a company adopts the new rules early.
How will the FCA supervise UK SRS reporting?
The FCA says it will monitor and enforce compliance with its rules along with the FRC, and will publish updated information on its supervisory approach in the second half of 2027, ahead of the first reporting season in 2028.
