UK SRS FAQ

The UK SRS are sustainability disclosure standards developed for UK markets, aligned with the ISSB global baseline standards (IFRS S1 and S2).

They require companies to disclose information about sustainability-related risks and opportunities that could affect their financial performance.

UK SRS are specifically designed for UK markets and aligned with ISSB standards.

UK SRS is voluntary today, like GRI or SASB. What would set it apart is the FCA’s CP26/5 proposal to require in-scope listed companies to report against it — a proposal that has not yet been made into a rule.

UK SRS S1: General requirements for sustainability-related financial disclosures
UK SRS S2: Climate-related disclosures (including governance, strategy, risk management, and metrics)

It has not been made mandatory, and no date has been set. The FCA has proposed, in CP26/5, that in-scope listed companies report against UK SRS S2 for accounting periods beginning on or after 1 January 2027. Around 600 listed companies would be affected, of which 515 — UKLR categories 6, 16 and 22 — would be required to comply; the 89 in categories 14 and 15 would make a signposting statement instead.

The FCA says it aims to publish its Policy Statement in autumn 2026, subject to the final UK SRS, with the rules coming into force from 1 January 2027. Until then UK SRS is available for voluntary use only.

• Assess current sustainability data collection capabilities
• Review governance structures for sustainability oversight
• Begin measuring Scope 1, 2, and 3 emissions if not already doing so
• Conduct climate scenario analysis
• Engage with stakeholders on material sustainability topics

CP26/5 proposes UK SRS reporting for UKLR categories 6, 16 and 22 only. UKLR 14 and 15 are within the consultation’s scope but are not proposed for UK SRS disclosure — they would instead make a statement identifying the overseas standards they follow, or a nil statement.

Certain disclosure requirements may also be phased in gradually.

Initially, UK SRS will apply to companies with securities admitted to trading on UK regulated markets (primarily UKLR category 6 companies on the London Stock Exchange).

The scope may later be extended to other market segments.

Initially, no.

UK SRS requirements will first apply to listed companies.

However, private companies may choose to adopt UK SRS voluntarily, especially if they are considering future listing or have stakeholder pressure.

Listed companies will need to report on sustainability matters across their entire group, including subsidiaries.

This means subsidiaries will need to provide data and information to support their parent company's UK SRS disclosures.

UK SRS disclosures will likely be included in annual reports, alongside financial statements.

Companies may also publish sustainability information in separate reports, but key disclosures will need to be in the annual report.

Assurance requirements are still being determined.

The FCA is considering requirements for limited assurance on sustainability disclosures, potentially progressing to reasonable assurance over time.

Specific penalties have not yet been announced.

However, as UK SRS will be part of listing rules, non-compliance could result in FCA enforcement action, including public censure and financial penalties.
