UK SRS by the numbers
Nine canonical figures that anchor the UK Sustainability Reporting Standards regime — every figure pinned to a primary source. The framing on this page sits behind every other reference page on the site.
Last verified 12 May 2026 · Updates as regulators publish new figures
UK SRS S1 (General Requirements) and UK SRS S2 (Climate-related Disclosures) released for voluntary use immediately, alongside the Government Response to the consultation.
DBT · UK SRS S1 and S2 publication
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.
FCA · CP26/5 PDF · Chapter 3
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
The UK SRS regulatory timeline
Five-year path from the Technical Advisory Committee's first endorsement recommendation to the proposed comply-or-explain mandate for broader sustainability disclosures. Three regulators, two committees, one set of standards.

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.
Where the FCA process currently stands
UK SRS S2 is not yet mandatory for any company. The Financial Conduct Authority's CP26/5 process moves through five sequential stages — three are complete, two remain. Until the Policy Statement is issued, mandatory dates are FCA proposals, not law.
Last verified 12 May 2026
The FCA published CP26/5: Aligning listed issuers' sustainability disclosures with international standards, proposing to replace the existing TCFD-aligned Listing Rules with rules requiring in-scope listed companies to apply UK SRS S2 from 1 January 2027 and UK SRS S1 on a comply-or-explain basis.
The seven-week consultation drew responses from listed companies, institutional investors, accounting and assurance bodies, and trade associations. Material substantive submissions arrived from large asset managers and pension funds.
The FCA is reviewing consultation responses and preparing its final Policy Statement. Three outcomes are possible: adopt the proposals as drafted; modify them in light of consultation feedback; or delay the timeline.
If the Policy Statement adopts the proposed timeline, the new UKLR rules would apply to accounting periods beginning on or after 1 January 2027 for in-scope listed companies.
The first mandatory UK SRS S2 reports would appear in annual reports published around six months after each in-scope company's year-end.

UK SRS Readiness Survey Q1 2026
Comprehensive analysis of FTSE 350 preparation levels, revealing significant gaps in Scope 3 data collection and scenario analysis capabilities. Key findings: 67% have begun preparation, but only 23% have robust financed emissions frameworks in place.

Expert analysis of the FCA's autumn 2026 policy statement timeline, potential changes to CP26/5 proposals, and implications for January 2027 implementation. Industry consultation responses suggest possible modifications to Scope 3 transitional reliefs.
Read commentary →Implementation Patterns & Cost Analysis
Early market intelligence suggests significant variation in UK SRS preparation approaches across sectors and company sizes. Financial services institutions lead in financed emissions methodology development, while industrial companies focus on supply chain engagement frameworks.
Implementation costs are trending higher than initial estimates, with median first-year expenditure reaching £2.1m for FTSE 100 companies. Key cost drivers include external consultancy support (38% of budget), technology platforms (27%), and internal resource allocation (35%).
The 18-month average timeline for comprehensive Scope 3 data collection reflects the complexity of value chain engagement and supplier onboarding processes. Early adopters are gaining competitive advantages through enhanced investor confidence and improved ESG ratings.
