UK SRS reporting, sorted.

The UK Sustainability Reporting Standards (UK SRS) are the UK government’s new framework for sustainability-related financial disclosures, replacing TCFD-based reporting requirements for large UK companies. Developed by the UK Endorsement Board and shaped by the Independent Technical Advisory Committee and Policy and Implementation Committee, UK SRS S1 and S2 were published on February 25, 2026. The standards are UK versions of the ISSB’s IFRS Sustainability Disclosure Standards (IFRS S1 and IFRS S2), adapted to the UK context to create a credible global baseline for UK sustainability reporting.

UK SRS aim to standardize sustainability reporting across UK entities, ensuring that sustainability-related financial information is consistent, comparable, and decision-useful. Unlike the EU’s CSRD, UK SRS include a transition relief that lets companies focus their disclosures on climate-related risks and opportunities, without being required to report on wider sustainability disclosures beyond climate, making it a more targeted starting point for UK sustainability reporting requirements.

UK SRS are available for voluntary use from 2026, covering fiscal year 2025 data, giving in-scope companies time to build UK SRS readiness ahead of mandatory requirements. Mandatory UK SRS reporting is expected to begin progressively for accounting periods beginning on or after January 1, 2027, with the first UK SRS-aligned reports due in 2028. The Business and Trade Secretary is expected to introduce requirements through UK legislation, with the FCA separately consulting on UK SRS adoption for listed companies; the final list of in-scope companies is anticipated in Autumn 2026.

The mandatory scope under the Companies Act is still being finalized as of 2026, with the Policy and Implementation Committee overseeing the rollout. Economically significant companies and certain UK entities on regulated markets are most likely to fall within scope first, while smaller unlisted firms may remain exempt. Companies that begin voluntary adoption now will be far better positioned than those that treat UK SRS as a last-minute compliance exercise.

UK SRS requirements are structured around four pillars: governance, strategy, risk management, and metrics and targets. UK SRS S1 sets out general requirements for the disclosure of sustainability-related financial information within the strategic report or financial statements, while UK SRS S2 addresses climate-related financial disclosures specifically, including climate-related risks, scenario analysis, transition plans, and emissions data covering Scope 1, 2, and 3. Companies must also address financed emissions where relevant, and UK SRS includes a UK-specific datapoint on the impracticability of estimating financed emissions reliably.

A key difference from global ISSB standards is that SASB industry-based metrics are voluntary under UK SRS rather than mandatory, and a transition relief allows companies to limit their UK SRS disclosures to climate-related risks and opportunities only, deferring wider sustainability disclosures. Material sustainability risks that affect enterprise value must still be disclosed within the strategic report, ensuring that UK SRS disclosures remain substantive and go well beyond a tick-box reporting exercise.

The UK SRS replace the Task Force on Climate-related Financial Disclosures (TCFD) framework as the basis for mandatory climate-related financial disclosures for large UK companies. While TCFD was a voluntary standard that the UK government incorporated into law, UK SRS is a formal, enduring regulatory standard built on the International Sustainability Standards Board’s global baseline, designed to align UK sustainability reporting with global standards and improve the comparability of corporate disclosures across jurisdictions.

UK SRS S2 goes further than TCFD in several areas: it introduces more detailed sustainability reporting requirements around scenario analysis, quantitative climate-related financial impacts on financial performance, transition plan disclosures, and Scope 3 emissions data. UK companies already reporting climate-related disclosures under TCFD will find significant overlap with UK SRS S2, but should conduct a gap analysis to identify new disclosure requirements and ensure their sustainability data and risk management processes meet the higher bar set by UK SRS standards.

The mandatory scope of UK SRS is still being finalised under UK legislation as of 2026. Mandatory reporting requirements are expected to apply to economically significant entities and certain UK-listed companies for accounting periods beginning on or after January 1, 2027. The FCA is expected to publish its final list of in-scope companies in Autumn 2026, and the Business and Trade Secretary will introduce requirements through the Companies Act for other economically significant companies. Smaller unlisted firms are likely to remain outside mandatory scope initially.

Even for companies not yet subject to mandatory UK SRS requirements, voluntary adoption now is strongly recommended to avoid UK SRS becoming a last-minute compliance exercise. Building the governance structures, risk management frameworks, sustainability data collection processes, and sustainability assurance capabilities required for UK SRS readiness takes time, and early voluntary use of the standard ensures companies are prepared well before mandatory reporting deadlines arrive.

Sweep’s dedicated UK SRS module covers all 214 disclosure datapoints across UK SRS S1 and UK SRS S2, fully aligned with the UK government’s published sustainability reporting standards. The module provides ready-to-use frameworks for collecting sustainability data, automating sustainability disclosures, and generating audit-ready exports, ensuring UK SRS readiness without turning compliance into a burdensome reporting exercise. Sweep also supports sustainability assurance workflows, helping companies prepare their UK SRS disclosures for independent review.

For companies transitioning from TCFD, Sweep maps existing climate-related disclosures to UK SRS S2 and surfaces any compliance gaps across governance, risk management, scenario analysis, and emissions data. UK SRS datapoints are pre-mapped to CSRD, GHG Protocol, and GRI indicators, so sustainability data collected for UK SRS requirements can be reused across other frameworks, reducing duplication for companies with reporting obligations in multiple jurisdictions.

Yes. Sweep’s UK SRS module includes both UK SRS S1 (General Requirements for Disclosure of Sustainability-related Financial Information) and UK SRS S2 (Climate-related Disclosures), as published by the UK Endorsement Board on February 25, 2026. The module contains 214 datapoints and is fully aligned with UK SRS terminology and guidance, incorporating the UK-specific adaptations made to the underlying IFRS Sustainability Disclosure Standards, including the voluntary status of SASB metrics and the UK SRS-only financed emissions datapoint.

Sweep’s UK versions of the standards accurately reflect all differences between UK SRS and the global ISSB standards, including the transition relief enabling climate-focused disclosure and the removal of ISSB-only datapoints not applicable under UK SRS. As UK regulators finalize mandatory requirements and accounting periods, Sweep’s framework will be updated to keep in-scope companies aligned with the latest UK SRS standards without additional manual effort.

Sweep supports a comprehensive suite of global sustainability reporting standards, including ISSB IFRS S1 and S2, the EU’s CSRD and ESRS frameworks, GHG Protocol, GRI, and TCFD-aligned climate-related financial disclosures. This means UK companies with reporting obligations in multiple jurisdictions can manage all their sustainability reporting requirements in one platform, rather than running separate, disconnected reporting exercises across frameworks.

Because UK SRS datapoints are pre-mapped to CSRD, GHG Protocol, and GRI indicators within Sweep, sustainability data collected for UK SRS disclosures can be seamlessly reused across other reporting standards. For non-UK companies or UK entities with EU operations, this cross-standard approach ensures consistent, comparable sustainability performance data across all major global standards, supporting the broader push toward harmonized corporate disclosures in sustainable finance.
