Collect the data once, map it to every UK SRS disclosure, and hand your assurance provider a report they can sign. Built for UK companies preparing while the standards are still voluntary and the FCA rules are still being written.
The UK Sustainability Reporting Standards are the UK’s own sustainability disclosure standards. The Department for Business and Trade published the final versions, UK SRS S1 and UK SRS S2, on 25 February 2026. They are UK adaptations of the ISSB’s IFRS S1 and IFRS S2, with six changes made for the UK context.
UK SRS S1 covers sustainability-related financial information in general. UK SRS S2 covers climate. Both are built around governance, strategy, risk management, and metrics and targets. Both take a financial materiality view, so the test is whether the information could affect enterprise value. That is the main difference from the EU’s CSRD, which asks a much wider question.
Most of what is written about UK SRS online dates from February 2026 and has not been revised since. Here is the position now.
DBT published UK SRS S1 and S2 on 25 February 2026, after a consultation that ran from June to September 2025 and drew 209 responses. Publishing a standard and requiring it are separate acts by different bodies. DBT published. The FCA has consulted on requiring it and has not yet published its rules.
The FCA’s consultation, CP26/5, opened on 30 January 2026 and closed on 20 March 2026. The FCA aims to publish its Policy Statement in autumn 2026, with rules applying to accounting periods beginning on or after 1 January 2027. That timing is conditional and the FCA’s own word is “aim”.
Until the Policy Statement lands, the requirement listed companies are actually subject to is the comply-or-explain TCFD statement under UKLR 6.6.6R(8). Unlisted companies sit on a separate DBT track, with no timetable set.
The FCA’s proposals cover roughly 515 issuers. That is a narrower population than the coverage suggests, and it is worth confirming your own perimeter before committing resource.
Two things get conflated here. UK SRS is voluntary for everyone today. That is not the same as saying climate reporting is voluntary for everyone. Large UK companies and LLPs over the 500-employee test have carried a mandatory climate disclosure obligation under SI 2022/31 and SI 2022/46 since 2022, independently of anything the FCA decides about UK SRS.
UK SRS S1 asks you to disclose sustainability-related risks and opportunities that could reasonably affect your prospects, across governance, strategy, risk management, and metrics and targets. Disclosure sits in the strategic report or alongside the financial statements, published at the same time, and it is expected to connect to the financial statements rather than sit beside them.
UK SRS S2 applies the same four pillars to climate and asks for more than TCFD did. Physical and transition risks at the level of the assets they touch. Climate resilience tested through scenario analysis, with method and assumptions disclosed. Transition plan disclosure where a plan exists. Scope 1, Scope 2 and Scope 3 emissions on GHG Protocol methodology, with Scope 3 broken out by category. Cross-industry metrics covering transition and physical risk exposure, capital deployment, internal carbon prices and remuneration linkage.
If you already report under IFRS S1 and S2 elsewhere, you are close. If you report under CSRD, you are not: CSRD runs on double materiality and asks a wider set of questions. Both can be produced from the same underlying data, which is the argument for a single ESG data layer rather than two projects.
If you already file a TCFD statement you have the structure. The four pillars carry over unchanged. What is usually missing is depth and evidence.
The gap is rarely about drafting. It is about whether the numbers behind the narrative can be traced to a source when an assurance provider asks. Credibl maps your existing TCFD statement against UK SRS S2 and shows which disclosures already have evidence and which are narrative alone.
See our TCFD reporting software →UK SRS coverage is usually tracked in a spreadsheet that one person maintains and nobody trusts. Credibl holds each S1 and S2 disclosure requirement as a structured item with an owner, a deadline, an evidence field and a review state. Coverage shows as a percentage of requirements evidenced, not as a judgement call made the week before the board meeting.
UK SRS S2 turns on emissions and scenario analysis, and both fall over for the same reason: the working is not reproducible a year later. Credibl calculates Scope 1, 2 and 3 on GHG Protocol methodology with DEFRA factors for UK operations, and stores the factor version alongside every calculation.
Most UK companies preparing for UK SRS are already filing SECR, and many sit inside ESOS. Run as three exercises, they collect the same energy and emissions data three times and reconcile it never. Credibl maps each figure once and reuses it. Restate a prior year and every disclosure drawing on it moves together.
Assurance arrives with UK SRS rather than after it. The FRC’s UK version of the international sustainability assurance standard, ISSA (UK) 5000, applies to periods beginning on or after 15 December 2026. The FRC is establishing an interim register of sustainability assurance practitioners, targeted for 2026. CP26/5 does not propose mandatory assurance from year 1, though the FCA has asked for views on requiring it in due course.
Assurance turns on evidence, not narrative. Credibl gives your assurance provider read-only access to the same environment your team works in, with multi-level approvals, complete change history and source documents attached to the figures they support. The provider receives an evidence pack rather than a folder of spreadsheets and a phone number.
How audit-ready ESG reporting works →UK SRS spreads across finance, risk, operations and sustainability, and most of the effort is unglamorous: chasing a site manager for a gas reading, matching procurement lines to emission factors, checking whether last quarter’s anomaly was real.
Your team reviews decisions. It stops doing data entry.
Collects and validates activity data across sites and suppliers.
Tracks regulatory change and interrogates the data behind every figure.
Runs the emissions calculations and DEFRA factor matching.
Drafts disclosure narrative from your own approved figures.
Runs the checks before anything goes to assurance.
Entities mapped against the FCA proposals and the DBT private company track, so effort goes where the obligation is likely to land.
Existing TCFD statement mapped to UK SRS S2, each disclosure marked evidenced, partially evidenced or absent.
Meters, finance systems, fleet and procurement connected. Historic data loaded for baseline and comparatives.
Scope 1 and 2 recalculated on versioned DEFRA factors, material Scope 3 categories screened and supplier collection launched.
Physical and transition scenarios run with assumptions recorded, governance and strategy disclosures drafted against structured requirements.
Evidence pack reviewed against ISSA (UK) 5000 expectations while the standards are still voluntary and a gap costs nothing.
Bring your last TCFD statement and your reporting perimeter. We’ll show you which UK SRS disclosures you can already evidence and which need work before the Policy Statement lands.
