UK SRS legislation — three Acts, thirteen sections

Three Acts of Parliament

Primary legislation underpinning UK sustainability reporting spans three Acts of Parliament:

• Companies Act 2006 — the dominant statute; provides the Strategic Report duty, content requirements, director liability, civil and criminal enforcement, and the s.414CB(2A) national reporting framework designation
• Financial Services and Markets Act 2000 — establishes the Financial Conduct Authority; provides listing rule-making powers and FCA enforcement mechanisms including financial penalties under section 206
• Energy Act 2023 — provides the powers under which SI 2023/1182 made the most substantial ESOS amendments since 2014; operates alongside CA 2006 framework

Statutory Instruments made under these Acts implement specific reporting requirements — covered in detail at UK SRS Legislation. This page focuses on the primary legislation itself.

Section 172 — directors\' duty to promote success of the company

Section 172 of the Companies Act 20062 imposes a statutory duty on directors to act in the way they consider, in good faith, would be most likely to promote the success of the company for the benefit of its members as a whole. In doing so, directors must "have regard" to six factors:

• The likely consequences of any decision in the long term
• The interests of the company's employees
• The need to foster the company's business relationships with suppliers, customers, and others
• The impact of the company's operations on the community and the environment
• The desirability of the company maintaining a reputation for high standards of business conduct
• The need to act fairly as between members of the company

The "Section 172(1) statement"2 is required in the Strategic Report of large entities under section 414CZA (inserted by SI 2018/860). The statement explains how directors discharged their section 172 duty during the financial year. UK SRS Governance pillar disclosures often overlap with the Section 172(1) statement — both address how the board considers stakeholder and environmental factors in decision-making.

Section 385 — quoted company definition

Section 385 of the Companies Act 20063 defines "quoted company" — a term with significant cascading effect across UK SRS and SECR scope. A "quoted company" means a company:

• Whose equity share capital has been included in the official list maintained by the FCA (UK Main Market)
• Or is officially listed in an EEA State (EEA regulated market)
• Or is admitted to dealing on either the New York Stock Exchange (NYSE) or the exchange known as NASDAQ

Critical: AIM admission alone does NOT make a company "quoted" under section 3853. AIM is operated by the London Stock Exchange under the AIM Rules — a market governed by exchange rules, not by the UK Listing Rules20. AIM-listed companies may be in SECR scope as large unquoted companies if they meet the two-of-three large threshold test under section 46512, but they are NOT automatically in scope by virtue of AIM admission.

The quoted company definition matters for:

• SECR scope under SI 2018/1155 — quoted companies in mandatory SECR scope regardless of size
• Historical 2013 Mandatory Carbon Reporting requirements (consolidated into SECR)
• Section 414CB climate-related financial disclosure regime — applies to traded companies (which includes quoted), among others

Section 414A — duty to prepare Strategic Report

Section 414A of the Companies Act 20064 imposes the statutory duty to prepare a Strategic Report for all non-small UK companies. The Strategic Report is the primary vehicle for UK SRS17 disclosure when UK SRS is applied voluntarily or under the section 414CB(2A) designation6.

Section 414A also defines the Strategic Report's general purpose: to inform members of the company about the company's performance, position, prospects, and the company's impact on the environment, society, and employees4. Subsequent sections specify content:

• Section 414B — small companies exemption
• Section 414C — main content requirements (business review, risks, KPIs, principal risks and uncertainties)
• Section 414CA — NFSIS for traded, banking, insurance, and similar companies
• Section 414CB — climate-related financial disclosure requirements (CFD regime)
• Section 414CZA — Section 172(1) statement

The Strategic Report is approved by the board of directors and forms part of the annual report and accounts filed with Companies House under section 441 of the Companies Act 20061.

Section 414CA — Non-Financial and Sustainability Information Statement

Section 414CA of the Companies Act 20065 requires "traded companies, banking companies, authorised insurance companies, and companies carrying on insurance market activity" to include a Non-Financial and Sustainability Information Statement (NFSIS) within the Strategic Report.

The NFSIS5 must cover, to the extent necessary for an understanding of the company's development, performance, and position:

• Environmental matters (including the impact of the company's business on the environment)
• The company's employees
• Social, community, and human rights issues
• Anti-corruption and anti-bribery

For each of these areas, the NFSIS5 must include:

• A description of the company's business model
• A description of policies pursued by the company
• A description of due diligence processes implemented
• Outcomes of those policies
• Principal risks relating to those matters
• Non-financial key performance indicators relevant to the company's business

Section 414CA5 was originally inserted into the Companies Act 2006 by SI 2016/1245 implementing the EU Non-Financial Reporting Directive (NFRD); the provisions were retained after Brexit. UK SRS S117 application generally satisfies the environmental and broader sustainability requirements within the NFSIS; specific compliance verification remains required.

Section 414CB(1)-(5) — climate-related financial disclosure

Section 414CB(1)-(5) of the Companies Act 20066 establishes the climate-related financial disclosure (CFD) regime. The provisions were inserted by SI 2022/3113 (Companies (Strategic Report) (Climate-related Financial Disclosure) Regulations 2022) and apply to accounting periods beginning on or after 6 April 2022.

Section 414CB6 applies to:

• Traded companies (broadly equivalent to quoted companies under section 385)
• Banking companies
• Authorised insurance companies
• Companies carrying on insurance market activity
• Other companies with over 500 employees and either annual turnover above £500 million or balance sheet total above £500 million
• LLPs meeting equivalent thresholds (under parallel LLP Regulations)

Section 414CB(1)-(5)6 requires the following content within the NFSIS or separate climate statement:

• A description of governance arrangements in place for assessing and managing climate-related risks and opportunities
• A description of how climate-related risks and opportunities are identified, assessed, and managed
• A description of how the identification, assessment, and management of climate-related risks is integrated into overall risk management
• A description of the principal climate-related risks and opportunities arising in connection with the company's operations
• A description of the time periods over which the climate-related risks and opportunities are assessed
• A description of the actual and potential impacts of the principal climate-related risks and opportunities on the company's business model and strategy
• An analysis of the resilience of the company's business model and strategy, taking into consideration different climate-related scenarios
• A description of the targets used by the company to manage climate-related risks and opportunities, and any KPIs used to assess progress against those targets
• A description of the climate-related risks and opportunities that the company has identified as material

This statutory list aligns substantially with TCFD recommendations20 and forms the foundation on which UK SRS S217 builds. The "CFD regime" — Linklaters' term — is how the CA 2006 implements climate disclosure for UK-incorporated companies whether or not they are listed.

Section 414CB(2A) — national reporting framework designation

Section 414CB(2A) of the Companies Act 20066 is the critical provision for UK SRS adopters. The subsection enables the Secretary of State to designate national reporting frameworks; entities applying a designated framework satisfy the disclosure requirements in section 414CB(1)-(5)6 without separate duplicate disclosure.

The FRC Sustainability Reporting FAQ (February 2026)19 confirms:

• DBT has designated UK SRS S2 as a national reporting framework under section 414CB(2A)
• UK entities applying UK SRS S2 do not need to duplicate climate-related financial disclosure requirements
• The designation applies regardless of whether UK SRS is applied on a mandatory or voluntary basis
• Conditions: use of UK SRS S2 must be clearly referenced in the NFSIS, and existing NFSIS requirements relating to climate-related financial disclosures set out in section 414CB(1)-(5) must be met

Section 418 — director criminal liability for non-compliant Directors\' Report

Section 418 of the Companies Act 20067 imposes personal criminal liability on directors in respect of the Directors' Report. The section is particularly relevant to SECR1 content (which sits within the Directors' Report) but the principle applies to all Directors' Report content.

Where the Directors' Report does not comply with statutory requirements, section 4187 provides that every director of the company who:

• Knew that the report did not comply, OR
• Was reckless as to whether it complied, OR
• Failed to take all reasonable steps to secure compliance

commits an offence. Maximum penalty on conviction: an UNLIMITED FINE7.

Section 4187 creates personal director liability beyond corporate liability. The director may be prosecuted in their personal capacity, with criminal record consequences. The "reasonable steps" defence requires demonstrating active oversight and reasonable assurance that the Directors' Report content is accurate and complete — not merely passive approval at board meetings.

In practice, criminal prosecutions under section 4187 are rare. The Companies Act framework prefers civil penalties under section 45310 for late filing as the primary routine enforcement. But the latent threat of section 418 prosecution provides significant deterrent — particularly for deliberate omissions of required disclosure, including SECR content.

Sections 442, 451, 453 — filing timing and consequences

Three Companies Act 2006 provisions govern the timing and consequences of annual report filing — including SECR content within Directors' Reports and UK SRS content within Strategic Reports.

Section 442 — filing deadlines

Section 4428 sets statutory filing deadlines for accounts and reports:

• Private companies and LLPs: 9 months after the end of the accounting reference period
• Public companies (PLCs): 6 months after the end of the accounting reference period
• Different deadlines reflect the public market disclosure considerations applying to PLCs

The 9-month / 6-month distinction is consequential and frequently misunderstood. Detailed coverage at SECR Filing Deadline.

Section 451 — criminal offence for failure to file

Section 4519 creates a criminal offence: directors who fail to take all reasonable steps to secure timely filing of accounts and reports are guilty of an offence. This applies to failure to file the entire annual filing, which includes SECR content (within the Directors' Report) and UK SRS content (within the Strategic Report). Section 451 operates alongside section 4187 — section 418 addresses non-compliant content; section 451 addresses failure to file at all.

Section 453 — civil penalty for late filing

Section 45310 imposes automatic civil penalties for late filing:

• Private company / LLP — £150 (up to 1 month late) to £1,500 (over 6 months late)
• Public company / PLC — £750 (up to 1 month late) to £7,500 (over 6 months late)
• Doubled if the company files late in two consecutive financial years
• Administered by Companies House

Civil penalties under section 45310 apply to the entire annual filing — they are not specific to SECR or UK SRS content. But because SECR sits within the Directors' Report and UK SRS (when applied) typically sits within the Strategic Report, late filing of the annual report is also late filing of the sustainability disclosure.

Section 463 — director safe harbour for false/misleading statements

Section 463 of the Companies Act 200611 provides important director protection — a statutory safe harbour for false or misleading statements in the Strategic Report, Directors' Report, and certain other reports.

Under section 46311, directors are only liable to compensate the company for losses caused by an untrue or misleading statement, or by dishonest concealment of a material fact, if they:

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

The Government Response to the UK SRS Consultation (February 2026)18 explicitly confirms that section 46311 protections apply automatically to UK SRS disclosure when included in the Strategic Report. The FRC Sustainability Reporting FAQ19 confirms the same position.

Section 46311 applies to SECR content (within the Directors' Report) and to UK SRS content within the Strategic Report. ESOS notifications submitted directly to the Environment Agency fall under a separate enforcement regime and do not benefit from section 463 protection.

Sections 465-467 — large company definition and two-year qualifying rule

Three Companies Act 2006 provisions define the "large company" status used across UK SRS, SECR, and other reporting regimes.

Section 465 — qualifying as medium-sized (and by extension, large)

Section 46512 establishes the size threshold tests. A company is "large" if it does NOT qualify as medium-sized, meaning it fails (exceeds) at least 2 of 3 thresholds:

• Turnover above £36 million
• Balance sheet total above £18 million
• Average number of employees above 250

SI 2024/13031 raised these thresholds with effect from 6 April 2025 for the broader Companies Act framework; SECR thresholds in SI 2018/1155 were NOT amended at the same time. Entities should not assume CA 2006 size category changes affect SECR.

Section 466 — group qualification

Section 46612 applies group aggregation rules for qualification. Parent and subsidiaries are tested together on:

• Aggregate (group) thresholds: net (consolidated) or gross (sum of individual entity figures)
• Net thresholds typically: £36m turnover / £18m balance sheet / 250 employees
• Gross thresholds typically: £43.2m turnover / £21.6m balance sheet / 250 employees
• Group exceeds large category if at least 2 of 3 thresholds met at either net or gross level

Section 467 — two-year qualifying rule

Section 46712 protects against one-off threshold fluctuations. A company remains in its current size category unless qualifying conditions FAIL in two consecutive years. One-off threshold fluctuations don't change SECR1 or UK SRS17 scope; sustained qualification or disqualification does.

FSMA 2000 — FCA powers

The Financial Services and Markets Act 200014 establishes the Financial Conduct Authority and provides the statutory basis for FCA-led aspects of UK SRS. Key provisions:

• Sections 1A-1B and Schedule 1ZA — FCA establishment and constitution
• Sections 1B-1L — FCA statutory objectives (consumer protection, integrity, competition)
• Part VI (sections 73A-103) — Official List and listing rules; FCA powers to make UK Listing Rules
• Sections 60-71 — Senior Managers and Certification Regime (SMCR) — personal accountability for senior managers of authorised firms
• Section 206 — financial penalties — FCA may impose financial penalties of up to 30% of relevant revenue derived from the breach

FSMA 200014 gives the FCA the rule-making power to implement UK SRS-aligned listing rules under CP26/520 WITHOUT requiring further parliamentary approval. The FCA can finalise CP26/5 rules in autumn 2026 and have them effective 1 January 2027 entirely within its own authority.

Energy Act 2023 — ESOS amendment context

The Energy Act 202316 is the third primary statute relevant to UK SRS legislation, though indirectly. Section 197 and Schedule 18 of the Energy Act 2023 provide the powers under which SI 2023/1182 (Energy Savings Opportunity Scheme (Amendment) Regulations 2023) made the most substantial ESOS amendments since 2014.

ESOS1 operates alongside the Companies Act 2006 framework — administered separately by the Environment Agency and devolved equivalents. The Energy Act 202316 is therefore relevant to the broader UK sustainability reporting landscape, even though UK SRS itself is anchored in the Companies Act 2006 + FSMA 2000 architecture.

How the provisions work together

The Companies Act 20061 provisions form a coherent statutory chain for UK sustainability reporting. Reading the chain end-to-end:

• Section 414A establishes the duty to prepare a Strategic Report for all non-small UK companies
• Section 414CA requires NFSIS within the Strategic Report covering environmental, social, human rights, and anti-corruption matters
• Section 414CB(1)-(5) requires climate-related financial disclosure within the NFSIS or separately — the CFD regime
• Section 414CB(2A) designates national reporting frameworks including UK SRS S2, eliminating duplication for UK SRS S2 adopters
• Section 172(1) statement explains how directors had regard to the six stakeholder factors including environment — basis for UK SRS Governance pillar
• Section 418 imposes director criminal liability for non-compliant Directors' Report (which includes SECR content)
• Section 442 sets filing deadlines — 9 months private/LLP; 6 months PLC
• Section 451 creates criminal offence for failure to file accounts and reports
• Section 453 imposes civil penalties for late filing — £150-£7,500 schedule, doubled for repeat
• Section 463 provides director safe harbour for good-faith disclosure including UK SRS content
• Sections 465-467 define size categories — relevant to scope of Strategic Report duty, SECR, and Section 172(1) statement requirement

Together, these provisions establish the statutory architecture of UK sustainability reporting. UK SRS17 operates within this architecture — not as a separate regime, but as a designated framework satisfying the climate disclosure requirements of section 414CB(1)-(5)6 via the section 414CB(2A) designation6, while sitting within the Strategic Report duty under section 414A4 and benefiting from section 46311 director protection.

Upcoming legislative development

The Government has indicated multiple times that the Companies Act 20061 will be amended during 2026-2028 to extend UK SRS17 application beyond listed companies. Key developments to monitor:

MCR Strand 2 consultation

The Modernising Corporate Reporting programme Strand 218 will consult on extending UK SRS application to economically significant private companies through Companies Act 2006 amendments. The consultation is expected during 2026. Likely to 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 for first-year reporters
• Assurance arrangements
• Interaction with SECR for entities brought into UK SRS scope

MCR Strand 1 simplification

MCR Strand 118 reduces reporting obligations for smaller entities through changes to the Strategic Report and Directors' Report. Approximately 51,000 companies expected to be exempted from Strategic Report requirements; estimated £230 million annual administrative savings.

FCA Policy Statement on CP26/5

The FCA Policy Statement on CP26/520 is expected in autumn 2026 and will finalise UK Listing Rules20 changes for listed company UK SRS mandatoriness. The FCA has authority to implement under FSMA 200014 WITHOUT further parliamentary approval — meaning the listed company changes can proceed independently of any Companies Act amendments.

The statutory framework is therefore evolving on two parallel tracks: FCA-led listed company changes (CP26/5 timeline 2026-2027), and DBT-led private company extension (MCR Strand 2 consultation during 2026, with effective date likely 2028 or later).
