UK SRS regulations — the four-layer framework

Layer 1 — Primary legislation

Primary legislation provides the statutory foundations for UK sustainability reporting.

Two Acts are central:

Companies Act 2006

The Companies Act 20064 is the primary statutory framework for UK corporate reporting.

Relevant provisions include:

• Section 414A — duty to prepare a Strategic Report for non-small companies
• Section 414CA — Non-Financial and Sustainability Information Statement (NFSIS) requirement
• Section 414CB — climate-related financial disclosure requirements; subsection (2A) enables Secretary of State designation of national reporting frameworks
• Section 418 — criminal liability for directors approving non-compliant Directors' Report (unlimited fine on conviction)
• Section 442 — filing deadlines (9 months private/LLP; 6 months PLC)
• Section 451 — criminal offence for failure to file accounts and reports
• Section 453 — civil penalty schedule for late filing
• Section 463 — director safe harbour for false or misleading statements (knowingly/recklessly/dishonestly only)
• Sections 416-419 — Directors' Report content requirements (incorporating SECR via SI 2018/1155)
• Section 465 — large company definition (two of three: turnover £36m+, balance sheet £18m+, employees 250+)
• Section 385 — quoted company definition (Main Market, EEA regulated, NYSE, NASDAQ — NOT AIM)

Financial Services and Markets Act 2000 (FSMA)

FSMA 20008 establishes the FCA's statutory basis and powers.

Key provisions:

• FCA establishment and statutory objectives (including market integrity and consumer protection)
• Listing rule-making powers (FCA can amend UKLR without further parliamentary approval)
• Supervisory and enforcement powers (FSMA s.206 financial penalties up to 30% of relevant revenue)
• Senior Managers and Certification Regime (SMCR) for authorised firms

Layer 2 — Statutory Instruments

Statutory Instruments (SIs) implement specific reporting requirements within the primary legislation framework.

Four SIs are particularly relevant to UK SRS:

SI 2013/1970 — Strategic Report Regulations

SI 2013/19709 (Companies Act 2006 (Strategic Report and Directors' Report) Regulations 2013) introduced the modern Strategic Report framework and the 2013 Mandatory Carbon Reporting regulations for quoted companies.

These provided the foundations on which subsequent regulations have built.

SI 2018/1155 — SECR Regulations

SI 2018/115510 introduced the Streamlined Energy and Carbon Reporting (SECR) regime, effective 1 April 2019.

The regulations amended Companies Act 2006 sections 416-419 to insert SECR-specific content requirements in the Directors' Report, and amended LLP Regulations to insert parallel requirements in the LLP Energy and Carbon Report.

SI 2024/1303 — Size threshold changes

SI 2024/130311 raised the Companies Act 2006 size thresholds (used for the "large company" definition) with effect from 6 April 2025.

Some entities moved down a size category — from large to medium, or medium to small — and became exempt from certain Strategic Report requirements.

Importantly, SECR thresholds in SI 2018/115510 were NOT amended at the same time; entities may have moved out of Strategic Report requirement but remain in SECR scope.

Anticipated MCR Regulations

The Modernising Corporate Reporting (MCR) programme13 may produce new Statutory Instruments during 2026-2028.

MCR Strand 1 simplification may amend Strategic Report requirements for smaller entities; MCR Strand 2 extension may amend Companies Act 2006 to bring economically significant private companies into UK SRS scope.

The consultation expected during 2026 will inform any resulting SI.

Layer 3 — FCA rules (UKLR + Handbook)

The FCA's rule-making powers under FSMA 20008 allow the regulator to set detailed rules for listed companies without requiring further parliamentary approval. UK SRS mandatoriness for listed entities is implemented through FCA rules.

UK Listing Rules (UKLR)

The UK Listing Rules12 were restructured in July 2024 from the previous Listing Rules.

The restructure introduced numbered categories 1-22, of which categories 6 (Commercial), 14 (Secondary), 15 (Depositary Receipts), 16 (Non-equity), and 22 (Transition) are most relevant to UK SRS scope.

The previous "premium" / "standard" listing distinction was eliminated in the UKLR restructure.

Pre-restructure regulatory language ("premium listed companies") is therefore outdated — current FCA terminology uses the numbered UKLR category system.

FCA Consultation Paper CP26/5

CP26/53 ("Aligning listed issuers' sustainability disclosures with international standards") was published by the FCA on 30 January 2026 and closed for responses on 20 March 2026 with 209 responses received.

The consultation proposes:

• UK SRS S2 proposed mandatory application for UKLR categories 6, 14, 15, 16, and 22 from accounting periods beginning on or after 1 January 2027
• UK SRS S1 application on a comply-or-explain basis
• Scope 3 emissions disclosure with first-year deferral plus optional additional one-year deferral
• Replacement of the current TCFD-aligned regime under LR 9.8 with UK SRS alignment
• UKLR 14 and 15 specifically: disclosure of home jurisdiction reporting requirements rather than UK SRS application (these are non-UK companies with secondary UK listings)
• Cross-referencing permitted under UK SRS S1 paragraph 65 for asset managers and other authorised firms disclosing under TCFD entity reports

The Policy Statement is expected during autumn 20263, with final rules effective 1 January 2027.

Other relevant FCA rules

• FCA Handbook — DTR (Disclosure and Transparency Rules) and PRR (Prospectus Regulation Rules) apply alongside UKLR for listed entities
• FCA Sustainability Disclosure Requirements (SDR) — Policy Statement PS23/16 (November 2023) for fund labelling and asset manager disclosure (separate but related regime)
• FCA Decision Procedure and Penalties Manual (DEPP) — supervisory and disciplinary procedures
• Senior Managers and Certification Regime (SMCR) — applies to senior managers of authorised firms including in connection with UK SRS disclosure quality

Layer 4 — Standards (UK SRS + ISSA)

Standards define the technical content of disclosure and the methodology for assurance.

UK standards are published by DBT (UK SRS) and FRC (assurance and other accounting/reporting standards).

UK SRS S1 and S2

UK SRS S11 (General Requirements for Disclosure of Sustainability-related Financial Information) and UK SRS S21 (Climate-related Disclosures) were published by DBT on 25 February 2026.

The standards are based on IFRS S1 and S2 published by the ISSB in June 2023, with six specific UK amendments accepted by the UK government2.

Key UK-specific amendments12:

• Removal of first-year delayed reporting relief — climate disclosure must be published with financial statements
• Industry-based guidance "shall" → "may" — companies expected to disclose industry-relevant metrics but not required to use SASB-based guidance specifically
• Other amendments addressing UK-specific reporting context and proportionality

ISSA (UK) 5000

ISSA (UK) 500014 was published by the Financial Reporting Council on 12 November 2025, effective for periods beginning on or after 15 December 2026.

The standard provides methodology for sustainability assurance — both limited and reasonable assurance levels — applicable to UK SRS-aligned disclosures and other sustainability information.

Under FCA CP26/53, third-party assurance over UK SRS is voluntary.

Where companies obtain assurance, ISSA (UK) 500014 is the methodology reference.

Many UK financial institutions and large corporates plan to obtain limited assurance over UK SRS S2 from Year 1 of mandatory application.

Other relevant standards

• FRC Guidance on the Strategic Report (June 2022) — FRC expectations for Strategic Report content
• FRS 102 (UK GAAP) — financial statement standards interacting with UK SRS connectivity requirements
• UK Corporate Governance Code 2024 (FRC) — governance framework interacting with UK SRS Governance pillar
• FRC Sustainability Reporting FAQ (February 2026) — practical interpretation of UK SRS application

Five regulators, distinct roles

The four-layer regulatory architecture is implemented by five regulators with distinct roles:

DBT — policy lead

The Department for Business and Trade1 is the policy lead for UK SRS.

DBT publishes the standards themselves, leads the Modernising Corporate Reporting programme, and coordinates with FCA on listed company implementation.

DBT activity to date1213:

• Published UK SRS S1 and S2 on 25 February 2026
• Published Government Response to UK SRS Consultation simultaneously
• Issued letter to FCA dated 5 January 2026 on UK SRS transitional reliefs alignment with FCA rules
• Issued Written Ministerial Statement on 21 October 2025 confirming MCR programme direction
• MCR Strand 1 simplification — approximately 51,000 companies exempted from Strategic Report; ~£230 million annual administrative savings
• MCR Strand 2 extension — consultation expected during 2026 on extending UK SRS to economically significant private companies

DBT does not directly enforce UK SRS — it produces the standards and policy direction.

Enforcement runs through FCA (for listed companies), Companies Act mechanisms (for all companies), and FRC corporate reporting review (for disclosure quality).

FCA — listed company mandatoriness

The Financial Conduct Authority3 implements UK SRS mandatoriness for listed companies through the UK Listing Rules12.

FCA powers derive from FSMA 20008.

FCA activity3:

• Published CP26/5 on 30 January 2026 proposing UK SRS-aligned rules for UKLR 6/14/15/16/22 from 1 January 2027
• Consultation closed 20 March 2026 with 209 responses
• Policy Statement expected autumn 2026 — will set final rules
• Has authority to implement final rules without further parliamentary approval
• Will replace existing TCFD-aligned regime under LR 9.8

FCA enforcement powers817:

• Supervisory action under FCA Handbook (warnings, undertakings, public censure)
• Financial penalties under FSMA 2000 s.206 — up to 30% of relevant revenue
• Listing suspension or cancellation under UKLR enforcement
• Senior Managers and Certification Regime (SMCR) — personal accountability for senior managers of authorised firms
• Decision Procedure and Penalties Manual (DEPP) sets out FCA decision-making and penalty framework

FRC — standards and quality oversight

The Financial Reporting Council1415 sits at the intersection of standards-setting and disclosure quality oversight.

FRC roles:

• Publishes ISSA (UK) 5000 — sustainability assurance methodology
• Publishes UK accounting standards including FRS 102 (UK GAAP) and FRS 101
• Publishes the UK Corporate Governance Code 2024 — governance framework
• Operates Corporate Reporting Review — quality oversight of annual reports including SECR and UK SRS content
• Publishes Sustainability Reporting FAQ — practical interpretation guidance
• Conducted 2025 thematic review of climate-related financial disclosures by AIM and large private companies
• Operates UK Stewardship Code — investor engagement framework

The FRC does not have direct sanctioning power for UK SRS disclosure quality — instead it reviews annual reports, engages with entities on identified issues, may require restatement, and publishes findings in its Annual Review of Corporate Reporting.

The FRC15 works alongside FCA enforcement (for listed companies) and Companies Act mechanisms (for all companies).

Companies House — filing and penalties

Companies House provides the administrative delivery layer for annual reports containing UK SRS, SECR, and other Strategic Report content.

Key functions:

• Receipt and publication of annual reports and accounts on the public register
• Application of CA 2006 section 453 civil penalties for late filing (£150-£7,500 depending on entity type and lateness, doubled for second consecutive late filing)
• Rejection of incomplete or non-compliant filings
• Director compliance records — Companies House register may be referenced in director disqualification proceedings

Companies House does not assess disclosure quality — that role sits with the FRC15 and (for listed companies) the FCA3.

Companies House operates the procedural compliance layer; substantive quality oversight runs through the regulators above.

Current state of consultations

CP26/5 — consultation closed, Policy Statement awaited

FCA Consultation Paper CP26/53 is the current focal point of UK SRS regulatory development.

Status as of May 2026:

• Published 30 January 2026
• Closed for responses 20 March 2026 — 209 responses received
• Policy Statement expected autumn 2026
• Final rules effective 1 January 2027 for accounting periods beginning on or after that date
• FCA has authority to implement without further parliamentary approval

Likely changes between CP26/5 and the final Policy Statement3:

• Refinement of UKLR 14 and 15 alternative disclosure approach in response to overseas issuer consultation feedback
• Clarification of cross-referencing rules and connectivity expectations
• Possible additional transitional reliefs for first-year reporters
• Refinement of Scope 3 deferral options
• Specific guidance on materiality assessment process disclosure

The FCA may also issue accompanying guidance or supervisory statements alongside the Policy Statement.

In-scope listed companies should plan for UK SRS S2 implementation based on CP26/53 proposals, recognising that specific requirements may be refined in the final rules.

MCR programme — Strand 1 and Strand 2

The Modernising Corporate Reporting programme13 is a parallel DBT initiative that will shape UK SRS regulation for unlisted entities.

Confirmed by Written Ministerial Statement on 21 October 2025:

Strand 1 — Simplification

MCR Strand 113 reduces Strategic Report and Directors' Report obligations for smaller entities.

Approximately 51,000 companies expected to be exempted from Strategic Report requirements, with estimated £230 million annual administrative savings.

Operational effect for SECR10: most Strand 1-exempted entities are smaller than SECR scope, so direct impact on SECR is limited.

The two-of-three test under Companies Act 2006 section 4654 continues to apply to SECR scope unaffected by MCR Strand 1.

Strand 2 — Extension

MCR Strand 213 may extend UK SRS1 application to economically significant private companies through Companies Act 20064 amendments.

The consultation expected during 2026 will address:

• Specific size thresholds (turnover, employee count, balance sheet)
• Entity scope (private companies, LLPs, PE-portfolio companies, family businesses)
• Timing of mandatory application
• Transition reliefs
• Assurance arrangements
• Interaction with SECR for entities brought into UK SRS scope

Earliest realistic effective date for mandatory private company UK SRS1: accounting periods beginning 2028 or later, given consultation timelines and legislative passage.

Section 414CB(2A) designation

Section 414CB(2A) of the Companies Act 20065 enables the Secretary of State to designate a national reporting framework.

This designation has substantial regulatory consequence for UK SRS adopters.

The FRC Sustainability Reporting FAQ15 confirms that DBT has designated UK SRS S21 under section 414CB(2A)5.

The designation means entities applying UK SRS S2 do not need to separately satisfy the climate-related financial disclosure requirements in section 414CB(1)-(5) of the Companies Act5.

The designation applies whether UK SRS S2 is applied mandatorily (in-scope listed companies under CP26/53) or voluntarily15.

Voluntary adopters benefit from the same simplification — UK SRS S2 application substitutes for the parallel CA 2006 climate disclosure requirements.

Section 463 director protection

Companies Act 2006 section 4637 provides a safe harbour for directors in respect of false or misleading statements in the Strategic Report, Directors' Report, and certain other reports.

Directors only compensate the company for losses caused by an untrue or misleading statement, or by dishonest concealment, if they:

• Knew the statement to be untrue or misleading, or were reckless as to whether it was untrue or misleading
• Knew an omission to be a dishonest concealment of a material fact

The Government Response to the UK SRS Consultation2 confirms that section 4637 protections apply automatically to UK SRS disclosure when included in the Strategic Report.

This is particularly significant for forward-looking UK SRS1 disclosures — scenario analysis, anticipated financial effects, and transition plans inherently involve uncertainty, and section 4637 provides safe harbour for good-faith disclosure that turns out to be inaccurate.

The protection applies equally to SECR10 content in the Directors' Report and to ESOS reporting where it falls within the Directors' Report.

ESOS notifications submitted directly to the Environment Agency do not benefit from section 4637 — they fall under a separate enforcement regime.

Enforcement tools by entity type

The UK SRS regulatory framework uses different enforcement tools for different entity types.

Two main streams:

Listed companies — FCA enforcement

FCA38 enforcement for listed company non-compliance under CP26/5 rules:

• Public censure under FSMA 2000
• Financial penalties under FSMA 2000 s.206 — up to 30% of relevant revenue
• Listing suspension or cancellation under UKLR
• Senior Managers and Certification Regime (SMCR) — personal accountability for senior managers of authorised firms
• Decision Procedure and Penalties Manual (DEPP) sets out procedure

Unlisted companies — Companies Act + FRC

Enforcement for unlisted entities and for Companies Act-derived obligations runs through Companies Act mechanisms4:

• Section 418 criminal liability for directors approving non-compliant Directors' Report (unlimited fine on conviction)
• Section 451 criminal offence for failure to file accounts and reports
• Section 453 civil penalties for late filing (£150-£7,500 depending on entity type, doubled for repeat)
• FRC Corporate Reporting Review — quality oversight with restatement requirements
• Companies House registration of late filing penalty notices
• Director disqualification under Company Directors Disqualification Act 1986 in cases of persistent default

Both streams may apply to the same entity.

A UK-listed company with poor UK SRS disclosure may face FCA enforcement for listing rule breach AND CA 2006 s.4184 director criminal liability for non-compliant Strategic Report.

The frameworks operate independently and cumulatively.

UK-specific amendments to IFRS S1/S2

The UK SRS1 retains close alignment with IFRS S1 and S2 published by the ISSB in June 2023, with six specific UK amendments2.

The amendments addressed UK-specific reporting context and the recommendations of the UK Sustainability Disclosure Technical Advisory Committee (UK SDR TAC).

The key amendments12:

• Removal of first-year delayed reporting relief — climate disclosure must be published WITH financial statements, unlike IFRS S2 which permits delayed reporting
• SASB Industry-based Guidance reference "shall" → "may" — companies expected to disclose industry-relevant metrics but not required to use SASB-based guidance specifically
• Clarification of materiality threshold for sustainability-related risks and opportunities
• UK-specific terminology and references where international terminology required adaptation
• Adjustments to financed emissions provisions (paragraphs B59-B66) for UK financial institutions
• Other refinements addressing UK reporting context

The retention of close IFRS S1/S2 alignment is a deliberate UK policy choice2 — UK SRS aims to function as the global baseline with minimum divergence, allowing UK entities to use UK SRS disclosure for international reporting purposes (subject to specific jurisdiction requirements).
