The UK government published finalised UK Sustainability Reporting Standards, UK SRS S1 and UK SRS S2, on 25 February 2026. They are closely based on the ISSB global baseline, but they include a targeted set of UK-specific amendments. For anyone preparing or advising on UK disclosures, knowing exactly where the two frameworks diverge has become a practical requirement rather than a technical detail.
This masterclass gives you a practical, expert-led comparison of UK SRS and the ISSB Standards. It covers the UK endorsement process, the roles of the Department for Business and Trade, the FCA and the Technical Advisory Committee, and each UK-specific amendment to S1 and S2 in turn.
The session focuses on applied learning throughout. Rather than restating the standards, it isolates the points of difference, explains the reasoning behind each amendment, and sets out what preparers need to do differently. It also covers the proposed FCA implementation timetable, the interaction between UK SRS and ESRS for entities reporting under both, and the UK assurance framework under ISSA (UK) 5000.
Key drivers behind the growing importance of this skill include the FCA's proposal to require UK SRS reporting for companies listed on the Main Market, the confirmation that UK SRS S2 satisfies existing climate disclosure obligations under the Companies Act 2006, and the dual reporting demands facing UK entities with EU operations in scope of the CSRD.
This masterclass assumes prior knowledge of IFRS S1 and IFRS S2. It is designed as an add-on for learners who have already completed the ISSB Pro course series.
The masterclass is delivered as a recorded session, approximately one hour long, and can be completed at your own pace.
