ESG reporting rules in the United Kingdom
The UK is moving towards ISSB-based reporting. Large companies already report climate information under existing UK rules such as SECR, and UK SRS S1 and S2 were published in February 2026. UK groups with large EU turnover may also fall under the EU’s CSRD.
UK SRS S1 and S2
The UK’s versions of the ISSB standards, published on 25 February 2026. Voluntary for now; the FCA has consulted on requiring them for listed companies from 2027, and no date is set for private companies.
