The UK Department for Business and Trade released the final UK Sustainability Reporting Standards (SRS S1 and S2) last week, building on ISSB frameworks to standardise sustainability disclosures for UK entities.
Initially voluntary, these standards target general sustainability risks (S1) and climate-specific issues (S2), enhancing data quality for investors without immediate mandates.
Analysts gain access to more granular, investor-focused disclosures across governance, strategy, risk management, metrics, and targets, expanding beyond TCFD‘s climate focus to financially material topics like biodiversity or supply chains. This supports precise portfolio risk modelling, with Scope 3 emissions required (full reporting by FY2028 under proposals) and metrics aligned to SASB standards. Investment teams can better quantify impacts on cash flows, capital costs, and enterprise value, cutting through inconsistent ESG data.
The FCA’s CP26/5 seeks views on mandating SRS S2 (replacing TCFD) for listed commercial companies from FY2027, with S1 on a “comply or explain” basis and third-party assurance disclosures. Scope 3 becomes mandatory in FY2028, full SRS by FY2029, with no transitional reliefs for early adopters. Disclosures can sit in annual reports or linked external documents, filed concurrently.
Timeline Milestone | Requirement
FY2027 | SRS S2 (climate risks)
FY2028 | Scope 3 emissions
FY2029 | Full S1 + S2
Unlike CSRD’s double materiality and stakeholder impacts, SRS emphasises single (financial) materiality, making it a streamlined evolution from TCFD for UK-listed firms. Investment teams benefit from consistent, assurance-ready data without CSRD’s broader data demands, though dual-reporting firms must align without bloating annual reports.
Map current disclosures to SRS gaps, integrate with risk frameworks, and draft streamlined content for investor messaging. At SI Engage, we help teams build roadmaps – to assess readiness, align risks, design disclosures, activate communications, and optimise reporting suites – to leverage this shift for competitive edge. Respond to the FCA consultation by 20 March 2026 to shape outcomes.
