UK Sustainability Reporting Standards (UK SRS) are the UK's implementation of ISSB standards, comprising S1 (general sustainability disclosures) and S2 (climate-related disclosures) standards published in February 2026. UK SRS requires comprehensive sustainability reporting aligned with global ISSB framework, superseding TCFD for listed companies from 2026-27.
First wave (2026-27): Premium and Standard listed companies, large banks and insurers with £5bn+ assets, asset managers with £50bn+ AUM. Second wave expected (2027-28): AIM-listed companies, large private companies with £500m+ revenue, major pension schemes. Voluntary adoption encouraged for all companies preparing for future public listing.
UK SRS is significantly more comprehensive than TCFD. While TCFD focuses on climate-related disclosures, UK SRS S1 covers all sustainability-related risks and opportunities. UK SRS S2 supersedes TCFD with mandatory Scope 3 emissions reporting, detailed transition plans, scenario analysis, and standardized metrics aligned with ISSB global standards.
UK SRS reporting becomes mandatory for first wave companies in their 2026-27 financial year. FCA consultation on implementation rules expected Q2 2025. Companies should start preparation immediately — gap analysis, data systems, governance structures, and supply chain engagement require 12-18 months minimum lead time.
With mandatory reporting starting 2026-27, early preparation is critical. Get expert UK SRS compliance advisory and avoid last-minute implementation costs.
