From 2026, the United Kingdom will begin phasing in mandatory climate-related disclosures under the UK Sustainability Reporting Standards (UK SRS). These disclosures are linked to the global International Sustainability Standards Board (ISSB) framework. The UK SRS plays a key role in the UK Government’s Sustainability Disclosure Requirements (SDR) framework, which aims to standardise reporting and increase transparency and corporate repsonsbility, primarily for investment decisions.
Companies will be required to publish their sustainability disclosures at the same time as their annual accounts from the first full accounting period from 2026 onwards. This means that companies must start to begin to collect robust data now to be ready to report.
Companies are only required to disclose client-related risks in the first two years, with wider sustainability aspects from Year 3 onwards. However, organisations are encouraged to report sustainability risks and opportunities earlier.
Unlike the EU Corporate Sustainability Reporting Directive (CSRD), which applies a double materiality approach – with both financial (how sustainability matters impact the entity) and impact (how the entity impact the environment, people and wider society) – the UK SRS primarily focuses on financial impacts.
