UK SRS S1 (General Requirements) and UK SRS S2 (Climate-related Disclosures) released for voluntary use immediately, alongside the Government Response to the consultation.

Approximately 500 issuers across UKLR 6 (Commercial), 16 (Non-equity), and 22 (Transition). UKLR 14 (Secondary) and 15 (Depositary Receipts) — around 40 more — face a flexible disclose-home-jurisdiction approach.

170 via online survey, 39 by direct email submission. 199 from organisations, 10 from individuals. 68% supported the four originally-proposed amendments.
Government Response · paras 1.6–1.7
Governance, Strategy, Risk Management, and Metrics and Targets. The structural foundation carried directly from TCFD (2017, disbanded 2023) — but disclosure requirements within each pillar are substantially enhanced.
UK SRS S2 · Paragraphs 5–37 · TCFD Recommendations
From purchased goods (Cat 1) to investments (Cat 15). Comply-or-explain under FCA proposals; one-year deferral available; proposed mandatory from January 2028.
UK SRS S2 · Paragraphs B33–B58 · GHG Protocol Scope 3
Forty-plus jurisdictions covering approximately 60% of global market capitalisation, 60% of global GDP, and 40%+ of global greenhouse gas emissions. Latest additions: Ethiopia and Peru (Feb 2026).
IFRS Foundation · ISSB Update · April 2026
KPMG, PwC, Deloitte, and EY implementation studies converge on this range for a mid-cap listed company to build the data infrastructure, materiality assessment, quantitative scenario analysis, and disclosure drafting needed.
KPMG · CP26/5 implementation analysis
Four originally proposed plus additional final-version changes: paragraph B59A added, effective dates removed, ISSB December 2025 amendments incorporated.
Government Response · Chapters 1–2
The FRC's UK adaptation of the IAASB international sustainability assurance standard. Covers both limited and reasonable assurance, applicable regardless of underlying reporting framework.
FRC · ISSA (UK) 5000
How long UK SRS S2 implementation actually takes
Companies waiting for the FCA Policy Statement to begin preparation are already late. Practitioner consensus puts end-to-end implementation at twelve to eighteen months — driven by Scope 3 data, which can't be compressed.

From kickoff to first UK SRS S2 report. Driven by Scope 3 supplier engagement and quantitative scenario modelling — neither compressible.
Of Scope 3 data work — from supplier engagement onset through validation. Of the 15 GHG Protocol categories, Category 1 and Category 11 typically account for >70% of total Scope 3 emissions.
Foundation phase before data work meaningfully begins. Materiality assessment and gap analysis are pre-requisites — running data collection without these creates wasted effort.
