Overseas companies and UK SRS

There is no separate UK SRS regime for overseas companies.

The FCA’s final rules (PS26/19, 30 September 2026) apply by listing category, not by incorporation: UKLR 6, 14, 15, 16 and 22 issuers report against UK SRS on a comply-or-explain basis from 2027.

That now includes secondary listings and depositary receipts, for which CP26/5 had proposed only a transparency statement.

The principle

Listing category, not incorporation

For overseas companies, UK SRS has no separate regime: UK SRS S1 and UK SRS S2 apply to any entity that uses them.

The FCA’s comply-or-explain rules apply based on listing category, not on incorporation.

The practical question for an overseas company is whether it has a UK primary listing, a UK secondary listing, a UK depositary receipt programme, or UK-incorporated subsidiaries.

Each position has a different answer, and this page sets out all four, with how the FCA’s rules sit beside home-jurisdiction standards.

For the broader listed-company regime, see who must comply with UK SRS, and the editorial reference on overseas companies and UK SRS at our sister site.

Case 1 · UK primary listing

Non-UK incorporated issuers with a UK primary listing

An overseas-incorporated company whose primary UK listing is in the commercial companies category (UKLR 6), the non-equity shares and non-voting equity shares category (UKLR 16), or the transition category (UKLR 22) is treated identically to a UK-incorporated issuer in the same category.

The FCA’s final rules apply to the entity by virtue of its UK listing category, not its incorporation.

From accounting periods beginning on or after 1 January 2027, these entities report against UK SRS on a comply-or-explain basis — the same basis as every UK peer, S2 included.

A company may use one year’s relief from disclosing Scope 3 and two years’ relief for UK SRS S1 non-climate matters, stating that it is doing so.

CP26/5 had proposed mandatory UK SRS S2 for these categories; the final rules adopt comply or explain instead.

CP26/5’s cost benefit analysis (Annex 2, paragraph 41) found non-UK incorporated issuers among those it would have covered in full — the clearest illustration that the perimeter is drawn by listing category.

An overseas-incorporated commercial company with a UK primary listing is a UK listed company for the purposes of the FCA’s rules.

For the full regime and its reliefs, see who must comply with UK SRS and the CP26/5 consultation tracker at uksrs.org.uk.

Final rules, for UKLR 6, 14, 15, 16 and 22

  1. 1 Jan 2027
    UK SRS S1 and S2, comply or explain

    Accounting periods beginning on or after this date; first reports in 2028.

  2. Year 1
    Scope 3 relief

    One year’s non-disclosure, stated as used.

  3. Years 1–2
    S1 non-climate relief

    Two years’ non-disclosure, stated as used.

Not a “UK companies” regime

Some overseas commentary characterises UK SRS that way. It is not: the FCA’s perimeter is defined by the UK Listing Rules.

Case 2 · UKLR 14 and 15

Secondary listings and depositary receipts: now in scope

CP26/5 paragraph 9.2 notes that the secondary listing category (UKLR 14) is open only to non-UK incorporated companies with a primary listing elsewhere; the depositary receipts category (UKLR 15) is for certificates representing shares in an overseas company.

CP26/5 proposed a transparency-focused statement for both — expressly not UK SRS-aligned disclosure.

The FCA’s final rules did not adopt it: UKLR 14 and 15 issuers report against UK SRS on a comply-or-explain basis for accounting periods beginning on or after 1 January 2027, like the other three categories (PS26/19 ¶3.6).

For the record: the statement CP26/5 proposed, and did not carry into the final rules

Source: FCA CP26/5 ¶9.4 — the consultation. Not adopted: under PS26/19 ¶3.6 these categories report against UK SRS on a comply-or-explain basis.
The proposed statement would have coveredDetail
Home-jurisdiction requirementsAny climate or wider sustainability disclosure requirements — including any transition plan requirements — in the primary overseas listing location or place of incorporation, signposted. Any relief or exemption used under those home rules must be explained.
Voluntarily adopted standardsAny climate or sustainability-related standards or frameworks, including for transition plans, that the entity has voluntarily adopted, signposted.
NeitherAn explicit statement that the entity is not subject to any such requirements and does not voluntarily follow any such standards.
AssuranceWhether third-party assurance has been obtained over any sustainability disclosures — and if so, the provider, the level, the standards used and where the report is.
What the consultation argued

CP26/5 said its approach did not involve the FCA making judgements on the legal or regulatory frameworks of other jurisdictions.

It was designed to avoid duplication for international issuers; the final rules instead apply the same comply-or-explain basis as for UK peers.

The consultation’s reasoning was anchored in the practical reality of ISSB adoption.

Paragraph 9.2 notes that “most” of the approximately 40 entities then in the secondary listing category are incorporated in jurisdictions that have indicated an intention to align with ISSB Standards.

That reasoning still matters in practice: an issuer already reporting against ISSB-aligned standards at home starts from a position close to UK SRS, and comply or explain lets it say where it has not applied a UK SRS requirement and why.

Home jurisdictions

What international issuers already report at home

For an issuer comparing its home reporting with UK SRS, the global trajectory of ISSB adoption matters; ISSB Standards are increasingly the international baseline.

The FCA’s cost benefit analysis (CP26/5 Annex 2, paragraph 41) notes that some of the non-UK incorporated issuers in scope are based in one of the 40 jurisdictions that have adopted, or are in the process of adopting, ISSB Standards.

IFRS Foundation · snapshots

Approach still in progress

Including Canada, China, South Korea, Switzerland and the United Kingdom itself — shown by the IFRS Foundation as a snapshot as at 26 September 2026, before the FCA’s final rules of 30 September.

The IFRS Foundation publishes a profile only once a jurisdiction’s approach is finalised; a snapshot is a preview, and the two should not be added together into a single “adopted” count.

Primary jurisdictionHome-jurisdiction position
AustraliaEntities meeting the Corporations Act 2001 thresholds prepare a sustainability report with climate disclosures under AASB S2, phased over three cohorts: annual periods commencing on or after 1 January 2025, then 1 July 2026, then 1 July 2027.
Hong KongHKEX climate requirements based on IFRS S2 apply from financial years commencing on or after 1 January 2025 — Scope 1 and 2 mandatory for all issuers, full requirements for LargeCap issuers from 1 January 2026. HKFRS S1 and S2, fully aligned with ISSB Standards, took effect on 1 August 2025 for voluntary application; HKEX plans to consult in 2027 on mandating them from 1 January 2028.
JapanThe FSA’s January 2026 roadmap and July 2026 amendments to the Financial Instruments and Exchange Act mandate the SSBJ Standards for Tokyo Stock Exchange Prime Market companies by market capitalisation: ¥3 trillion or more from the period ending March 2027, ¥1 trillion from March 2028, ¥500 billion from March 2029. The SSBJ Standards are designed to be functionally aligned with ISSB Standards.
European UnionCSRD reporting follows ESRS, which uses double materiality rather than ISSB’s financial materiality. EFRAG and the IFRS Foundation published joint interoperability guidance on 2 May 2024; ESRS reporting generally overlaps substantially with what UK SRS S2 would require. A UK secondary-listed entity whose primary listing is in the EU starts from its ESRS reporting when working through UK SRS on a comply-or-explain basis.
United StatesNo federal ISSB-aligned mandate. California’s SB 253 and SB 261 create state-level climate disclosure obligations, but they are not a national framework. A UK secondary-listed US entity starts from whatever voluntary standards it follows — the original TCFD recommendations, or voluntary ISSB application — when working through UK SRS on a comply-or-explain basis.

For the full comparison, see the editorial reference on the European Sustainability Reporting Standards and double materiality at our sister site.

Case 3 · UK subsidiaries

UK subsidiaries of overseas parents

Overseas groups with UK-incorporated subsidiaries that have no UK listing face a separate question.

The trigger here is UK incorporation, not the parent’s location.

The relevant regime is the climate-related financial disclosure provisions in section 414CB of the Companies Act 2006, as amended by the Companies (Strategic Report) (Climate-related Financial Disclosure) Regulations 2022.

A UK subsidiary of an overseas parent must make climate-related financial disclosures in its non-financial and sustainability information statement if it falls within section 414CA.

The required disclosures are the eight in section 414CB(2A): governance, identification and management of climate risks, principal risks and opportunities, business model impact, resilience analysis, targets, and key performance indicators.

The interaction with UK SRS is favourable

The FRC has confirmed that the Government has designated UK SRS S2 a national reporting framework for the purposes of section 414CB(6).

A UK subsidiary that uses UK SRS S2 — voluntarily, or under any future obligation — need not duplicate the section 414CB(2A) disclosures, provided its use of UK SRS S2 is clearly referenced in the statement.

The Modernising Corporate Reporting consultation of 7 September 2026 (paragraph 158) restates this: companies caught by both regimes “may choose to use their UK SRS S2 disclosures to meet its CFD obligations using section 414CB(6)”.

Group reporting exemptions may also apply where the subsidiary is included in a group strategic report prepared by its parent that satisfies the equivalent requirements; the conditions are in the Companies Act 2006 group reporting provisions.

The section 414CA test

Company typeEmployees
Traded, banking, authorised insurance, insurance market activity, or AIM companyMore than 500
“High turnover company” — turnover over £500mMore than 500

Single-entity basis where the subsidiary is not a parent; consolidated where it heads a sub-group (s.414CA(2A)). Companies Act 2006 s.414CA

Case 4 · Voluntary

Voluntary application by overseas entities

Any entity — UK-incorporated or otherwise — may apply UK SRS voluntarily.

The DBT consultation response confirms that the standards are available for use “in whole or in part, as they see fit.”

There is no UK approval or registration process.

Voluntary adopters state which standards they have applied and provide the corresponding disclosures.

Three reasons overseas entities adopt it

  1. 01
    UK investor base

    UK-aligned disclosure without being subject to UK rules.

  2. 02
    A future UK listing

    Build the reporting infrastructure in advance.

  3. 03
    Group consistency

    Apply at parent level where subsidiaries use UK SRS.

Next steps

What to do this year

UKLR 6, 16 or 22

Plan as a UK peer would

  • Map existing TCFD-aligned disclosures against UK SRS S2 and identify gaps — see climate scenario analysis under UK SRS for the paragraph 22 resilience requirement, one of the most material upgrades from TCFD.
  • Decide whether to use the transitional reliefs in the FCA’s final rules (PS26/19 ¶3.14) — one year for Scope 3, two years for S1 non-climate matters; CP26/5 paragraph 8.6 had proposed the same periods.
UKLR 14 or 15

Plan for UK SRS, not a statement

  • Map what you report in the primary listing jurisdiction or place of incorporation against UK SRS S1 and S2 — that is where comply or explain starts.
  • Identify voluntary standards followed (TCFD, ISSB Standards, ESRS, GRI, others) and where those disclosures are published.
  • If you obtain assurance, prepare to name the provider, the disclosures assured and the standards used.
UK subsidiaries

Check the Companies Act test

  • Confirm whether the subsidiary meets section 414CA.
  • Where it does, decide between the existing section 414CB(2A) disclosures and reference to UK SRS S2 under section 414CB(6).
  • Where the parent reports against ISSB Standards or ESRS, consider whether parent-level reporting can be relied on under the group provisions, and confirm with auditors.
