UK S1·Explainer·New standards and transition
Voluntary UK SRS S1 use can be valuable for a private or unlisted company when it improves a real decision: credit assessment, investment, owner oversight, customer due diligence, strategic planning or future reporting readiness. The company should start from intended users and material sustainability-related risks and opportunities, connect them to cash flows and financing, and apply proportionate data and controls.

A useful UK SRS S1 gap assessment is not a paragraph-by-paragraph tick-box exercise.

UK SRS S1 does not require an entity to use the SASB Standards, but it does require disclosed metrics to include metrics associated with particular business models, activities or other industry characteristics. A defensible process starts with material sustainability-related risks and opportunities, maps the entity's activities and industries, considers a complete candidate universe and then applies relevance, faithful-representation, materiality and comparability tests.
