Helps you decideWhat to build now, and what must remain an open legal or policy assumption.

Preparers should build a tagging-ready disclosure inventory and controlled human-to-machine mapping now, but they should not claim that UK SRS S2 sustainability tagging is currently mandatory under an FCA filing rule. The IFRS Sustainability Disclosure Taxonomy 2024 provides the logical starting point because UK SRS is based on IFRS S1 and S2, while UK amendments, reliefs and future filing choices require a difference register.
Helps you decideWhat can be prepared now, what requires an extension or version decision, and what remains a future-rule dependency.

UK S2·Explainer·New standards and transition
UK SRS S2 already incorporates the December 2025 IFRS S2 greenhouse-gas amendments from its first publication in February 2026.

Helps you decideWhich December 2025 changes are already part of UK SRS S2 and what implementation records must change.
