What statutory authority does the FCA have to mandate UK SRS?
The FCA has statutory authority under the Financial Services and Markets Act 2000 to set listing rules requiring sustainability disclosures. Section 73A specifically empowers the FCA to impose disclosure requirements on listed companies, which CP26/5 exercises to propose mandatory UK SRS S2 implementation from January 2027.
Which companies fall within FCA scope for UK SRS requirements?
Approximately 500 UK-listed companies with Premium Listing status will be in scope, including those under UKLR 6 (Commercial), 16 (Non-equity), and 22 (Transition) categories. Companies under UKLR 14 (Secondary) and 15 (Depositary Receipts) face a flexible home jurisdiction disclosure approach rather than mandatory UK SRS compliance.
How will the FCA enforce UK SRS compliance?
The FCA will enforce UK SRS requirements through its listing rules enforcement mechanisms, including public censure, financial penalties, and potential suspension of listing. The FCA's enforcement approach will follow existing precedents for financial disclosure violations, with sanctions proportionate to the nature and severity of non-compliance.
What is the comply-or-explain mechanism under FCA proposals?
For UK SRS S1 and certain Scope 3 requirements, companies must either provide full compliance or publish an explanation statement identifying which requirements are not met, reasons for non-compliance, and specific improvement plans with timelines. The FCA expects explanations to be substantive and demonstrate good faith efforts toward compliance.
How do FCA proposals interact with existing TCFD requirements?
UK SRS S2 will replace existing TCFD requirements for in-scope companies from January 2027. Companies currently subject to TCFD will transition to UK SRS S2, which builds on the TCFD four-pillar structure but requires enhanced disclosures, particularly on Scope 3 emissions and scenario analysis with quantitative impact assessment.
What happens if the Policy Statement differs from CP26/5 proposals?
The FCA Policy Statement (expected Autumn 2026) will provide final rules that may differ from CP26/5 proposals based on consultation responses. All timelines and requirements remain proposed until Policy Statement publication. Companies should prepare for the proposed timeline while monitoring for potential adjustments in scope, timing, or compliance mechanisms.
