UK SRS reporting guidance

Where UK SRS disclosures sit

This guidance addresses UK SRS implementation specifically. For the broader sustainability reporting context including UK reporting regimes outside UK SRS, see our landscape reference.

UK SRS1 disclosures sit within the existing UK corporate reporting architecture, not as a separate sustainability report. The Companies Act 2006 Strategic Report contains the Non-Financial and Sustainability Information Statement (NFSIS) under section 414CA4, and UK SRS disclosures live within NFSIS for entities applying UK SRS6.

This integration principle has practical consequences. Companies don't produce a separate sustainability report and a separate annual report; UK SRS disclosures become part of the same annual report production cycle, with the same governance, internal control, and assurance arrangements as the rest of the Strategic Report.

The primary UK SRS content sits in:

• The Strategic Report — where business model, principal risks, strategy, and outlook discussions integrate UK SRS sustainability content per section 414A [5]
• The NFSIS — the section 414CA [4] statement that contains the core UK SRS-specific disclosures including methodology under UK SRS S1 paragraphs 60-64 [1], metrics per paragraphs 27-36 [1], and comply-or-explain content
• The Corporate Governance Report — where companies prepare one under the UK Corporate Governance Code [11], the governance pillar may sit here with cross-references from the NFSIS per paragraph 65 [1]
• Notes to financial statements — where sustainability matters affect carrying amounts, recognition, measurement, or forward-looking estimates (connectivity principle from UK SRS S1 paragraph 66 [1])

NFSIS and section 414CB(2A)

Section 414CA of the Companies Act 20064 requires large UK companies to prepare a Non-Financial and Sustainability Information Statement (NFSIS) as part of the Strategic Report. Section 414CB3 sets out the climate-related financial disclosure requirements that the NFSIS must address.

Section 414CB(2A)3 allows the Secretary of State to designate a national reporting framework. The Department for Business and Trade has confirmed in the FRC FAQ6 that UK SRS S2 has been designated under section 414CB(2A) — meaning an entity applying UK SRS S2 does not need to separately satisfy the climate-related financial disclosure requirements in section 414CB(1)-(5)6, provided UK SRS S2 application is clearly referenced in the NFSIS.

This applies whether UK SRS S2 is applied on a mandatory basis (for in-scope listed companies under FCA CP26/52 from 1 January 2027) or voluntarily. Companies voluntarily applying UK SRS S2 still benefit from the section 414CB(2A) designation6.

Strategic Report integration

The Strategic Report is the central narrative document in UK corporate reporting, required by section 414A of the Companies Act 20065. The FRC's Guidance on the Strategic Report12 (June 2022) sets out the FRC's expectations for content, quality, and presentation.

UK SRS1 integrates with the Strategic Report rather than replacing it. The four pillars typically distribute across multiple sections:

• Business model description — incorporates UK SRS S2 paragraph 13 [1] (current and anticipated effects on business model and value chain) within the section 414A [5] business model requirement
• Principal risks discussion — incorporates UK SRS S2 paragraphs 25-26 [1] (Risk Management pillar) alongside existing principal risk disclosures per section 414A [5]
• Strategy and outlook — incorporates UK SRS S2 paragraphs 14 [1] (response to risks and opportunities) and 22 [1] (resilience and scenario analysis) within the Strategic Report forward-looking content
• Key performance indicators — incorporates UK SRS Metrics and Targets pillar (paragraphs 27-36 [1]) within the section 414A [5] KPI framework

The FRC's Guidance on the Strategic Report12 emphasises that the Strategic Report should be a coherent narrative document, not a collection of separately-presented disclosures. UK SRS content should be woven into the strategic narrative rather than appearing as a separate technical appendix.

Cross-references — UK SRS S1 paragraph 65

UK SRS S1 paragraph 651 permits entities to incorporate information by cross-reference to other sources within the annual report. Cross-references reduce duplication and support the integrated narrative principle.

Permitted cross-references1:

• Within the annual report — to the Corporate Governance Report, Audit Committee Report, Risk Management Report, financial statements, or other sections
• Must be clear and easily navigable — the user should not need to search to find the referenced content
• Cross-referenced content must be subject to the same level of assurance as the UK SRS-required content (where assurance is obtained) [8]

Cross-references outside the annual report1 (e.g. to standalone sustainability reports, websites, separate ESG documents) are not typically permitted for material UK SRS content — the disclosure must be within the annual report itself, not via external reference.

The practical effect: UK SRS encourages integrated reporting within the annual report, with strategic placement of content where it most logically belongs (governance in the Governance Report, metrics in the NFSIS, risk processes in the Principal Risks discussion) rather than concentrating everything in a sustainability appendix.

Connectivity with financial statements

UK SRS S11 requires sustainability disclosures to be connected to information in the financial statements. This connectivity principle has reporting placement implications.

Connection points typically include1:

• Carrying amounts — sustainability matters affecting impairment testing, useful lives, or carrying values of property, plant and equipment
• Provisions — sustainability-related provisions for environmental remediation, decommissioning, or transition costs
• Forward-looking estimates — climate transition assumptions affecting discounted cash flow models, useful life assumptions, or asset retirement provisions
• Going concern — material climate transition or physical risks affecting going concern assessment
• Recognition and measurement — sustainability matters affecting recognition criteria for assets, liabilities, or contingent items

Where connection points exist, the relevant financial statement note should reference the corresponding UK SRS disclosure, and vice versa. Assumptions used in sustainability disclosures must be consistent with those used in financial statements; where they differ, the difference must be explained1.

Timing within the reporting cycle

UK SRS S11 paragraph 60 requires that an entity's sustainability-related financial disclosures be reported as part of its general purpose financial reports — meaning at the same time as the financial statements, in the same reporting package.

For UK listed companies with December year-ends in scope of FCA CP26/52 mandatory application from accounting periods beginning 1 January 20272:

• Year-end accounting completes during January per typical UK reporting cycle
• Draft Annual Report typically takes 90-120 days from year-end under section 414A [5] requirements
• Auditor signs the audit report once Annual Report content (including UK SRS per paragraph 60 [1]) is substantially complete
• Board approves the Annual Report including UK SRS disclosures under section 414A [5] governance requirements
• Publication on the entity website and via Stock Exchange notification under FCA Listing Rules [10] typically late March / April

For Year 1 mandatory application (year-ends after 1 January 20272 for in-scope listed entities under CP26/52), the additional UK SRS content typically adds 2-4 weeks to draft preparation time — particularly for Scope 1 and 2 emissions calculation under paragraph 291, scenario analysis documentation under paragraph 221, and methodology disclosure under paragraphs 60-641.

No delayed reporting relief — UK amendment

IFRS S2 provides a first-year transition relief allowing climate-related financial disclosures to be published AFTER the financial statements. UK SRS S21 removes this relief.

The reasoning addresses the UK Strategic Report structure under the Companies Act5. UK listed companies publish their Strategic Report concurrently with the financial statements; introducing a permitted lag for climate disclosure would create a hybrid timing model inconsistent with existing UK reporting practice6.

The connectivity principle in UK SRS S11 also depends on simultaneous publication. Decoupling timing would weaken the connectivity in Year 1, which UK regulators considered unacceptable6.

The practical effect: companies cannot use the IFRS S2 first-year delayed reporting relief in the UK. Climate disclosures must be ready when the Annual Report goes to print. For Year 1 application, this is one of the more demanding operational constraints — Scope 1 and 2 measurement must be completed and verified, scenario analysis documented, and methodology disclosure prepared all within the standard annual reporting cycle.

Year 1 transition reliefs

UK SRS S21 provides three Year 1 transition reliefs that reduce the operational burden of first-year application:

No comparative period required

Year 1 disclosure of current period only — no requirement to restate prior period figures1. Comparatives are required from Year 2.

Alternative GHG measurement method

Year 1 entities may use a GHG measurement method other than the GHG Protocol Corporate Standard1, particularly relevant for entities transitioning from SECR methodology. Migration to GHG Protocol compliance expected from Year 2.

Scope 3 deferral

Scope 3 emissions disclosure may be deferred to Year 2 of mandatory application1. Plus FCA CP26/52 adds an optional additional one-year Scope 3 deferral on top of the standard relief. Combined effect: Scope 3 becomes comply-or-explain from accounting periods beginning 1 January 20282.

The transition reliefs apply only to Year 1 of mandatory application. Voluntary early adopters are encouraged but not required to use the reliefs — many large UK financial institutions have produced UK SRS-aligned voluntary disclosures from 2024-2025 without using transition reliefs.

Electronic format and iXBRL tagging

UK listed companies must produce annual reports in electronic format under FCA Listing Rules10. UK SRS disclosures must be tagged using inline XBRL (iXBRL) alongside the financial statements.

UK SRS S11 references the IFRS Sustainability Disclosure Taxonomy9 as the basis for digital tagging. The taxonomy provides standardised data structures for UK SRS-required disclosures — emissions data, scenario analysis, materiality assessment outcomes, climate-related targets, and methodology disclosures.

Practical implications9:

• Annual reports submitted to FCA's National Storage Mechanism include UK SRS content as machine-readable structured data
• Investors and analysts can extract structured UK SRS data via XBRL parsers
• Comparability across UK SRS-reporting entities is improved through structured tagging
• First-year application will likely involve manual tagging or hybrid approaches; mature implementations move toward automated tagging from source systems

Where assurance fits

FCA CP26/52 does not currently mandate third-party assurance of UK SRS disclosures. Where companies obtain voluntary assurance, ISSA (UK) 50008 is the UK sustainability assurance standard (published 12 November 2025, effective 15 December 2026).

Within the reporting cycle, assurance arrangements affect timing in several ways:

• Engagement letter typically issued 6+ months before year-end
• Risk assessment and planning during late Q3 / early Q4
• Interim procedures over controls during Q4
• Substantive procedures over period-end data during January-February
• Assurance report typically signed within 2-3 weeks of audit report
• Disclosure of assurance level, standard, and provider per FCA CP26/5 [2]

The Strategic Report (and hence UK SRS disclosures within it) is subject to limited assurance under the existing audit framework — the statutory auditor confirms the Strategic Report is consistent with the financial statements. Voluntary ISSA (UK) 50008 assurance is additional to this baseline.

Interim and half-year reporting

UK SRS S1 paragraph 691 sets out interim reporting expectations. Material updates to UK SRS disclosures should be reflected in interim reports where the entity prepares them — typically half-yearly financial reports for UK listed companies.

FCA CP26/52 does not propose specific interim sustainability reporting requirements at this stage. Interim financial reporting under FRS 104 or IAS 34 may include reference to material sustainability matters where they affect the period's results — for example, climate-related impairments, restructuring provisions linked to transition activity, or material changes in financed emissions assumptions for financial institutions.

The general principle: interim UK SRS reporting is event-driven rather than scheduled. Material changes to disclosures (new climate-related risks identified, target progress disclosure, scenario analysis updates) should be reflected when they occur. Routine annual UK SRS disclosure cycle remains the primary reporting mechanism.

Comparatives, errors, and restatement

UK SRS S1 paragraphs 67 and 701 address comparatives and restatement:

Comparatives (paragraph 67)

From Year 2 onwards, prior period comparative information must be disclosed alongside current period UK SRS metrics1. Year 1 transition relief allows no comparatives in the first year of mandatory application.

Errors and restatement (paragraph 70)

Where prior period errors are identified, restatement is required1 — restated comparative figures, disclosure of the error and the correction, and impact on previously reported information. The treatment mirrors financial statement error correction under IAS 8.

Sources of estimation uncertainty (paragraph 68)

Where UK SRS disclosures involve significant estimation uncertainty1 — typically forward-looking scenario analysis, anticipated financial effects, and Scope 3 estimation — the entity discloses the sources of uncertainty, the assumptions made, and the sensitivity of disclosed figures to assumption changes.

The internal preparation process

UK SRS preparation typically integrates into the existing annual reporting cycle. A typical process map:

• Q3 prior year — materiality assessment refresh, scenario assumptions review, KPI definition confirmation
• Q4 prior year / Q1 current year — data collection from operational systems, Scope 1 and 2 calculation, third-party data refresh
• Q1 current year — methodology documentation, scenario analysis update, target progress assessment, draft narrative
• Q1-Q2 current year — internal review by Sustainability Committee or equivalent, Risk Committee, Audit Committee
• Q2 current year — external assurance procedures (where obtained), draft Annual Report preparation, auditor review
• Q2 current year — Board approval, FCA / Companies House filing, publication

The audit committee plays a central role under both the UK Corporate Governance Code11 and the broader reporting framework. UK SRS disclosures sit within the audit committee's remit alongside financial reporting — the committee oversees the integrity of the Strategic Report, including UK SRS content.

MCR programme — what's coming

The Department for Business and Trade's Modernising Corporate Reporting programme7 was confirmed by Written Ministerial Statement on 21 October 2025. The programme will amend the Companies Act 2006345 to embed UK SRS more deeply in UK corporate reporting law.

Expected MCR developments7:

• Consultation on extending UK SRS application to economically significant private companies (expected during 2026)
• Threshold consultation — turnover, employee count, or balance sheet thresholds for private company scope
• Strategic Report exemptions for smaller entities (estimated 51,000 companies)
• Potential simplification of the Strategic Report content requirements
• Approximately £230 million estimated annual administrative savings from MCR Strand 1

The MCR programme7 is not yet at draft legislation stage. Companies should monitor the consultation timeline during 2026; in-scope listed companies under CP26/52 are not affected by MCR changes since their UK SRS application is already established. Currently out-of-scope private entities — particularly economically significant private companies — should track MCR developments closely.
