Overseas companies and UK SRS

Three overseas company scenarios

Overseas companies interact with UK SRS across three distinct scenarios1: companies with UK secondary listing (UKLR categories 14 and 15), UK subsidiaries of overseas parents, and UK branches of overseas companies.

Each scenario has different legal status, disclosure obligations, and practical implementation approaches.

The scenarios reflect different degrees of UK market presence and legal connection.

Secondary listed companies maintain overseas incorporation but access UK capital markets.

UK subsidiaries are separate UK legal entities with overseas ownership.

UK branches operate in the UK without separate incorporation4.

Understanding scenario classification is critical for determining UK SRS application because disclosure obligations depend on legal status rather than commercial presence.

An overseas company with significant UK operations but branch status faces different obligations than the same company with subsidiary structure.

Scenario 1 — Overseas companies with UK secondary listing (UKLR 14, 15)

Overseas companies with UK secondary listing under UKLR categories 14 (Secondary listing) and 15 (Depositary Receipts)6 face a flexible disclose-home-jurisdiction approach under FCA CP26/53.

FCA CP26/5 does not propose applying UK SRS to these companies.

Instead, they would make a statement identifying the overseas climate and sustainability standards they are subject to, or voluntarily follow, and signposting where those disclosures can be found — or, if none apply, a statement to that effect (CP26/5 ¶9.4, ¶9.6).

The flexible approach recognises that requiring overseas companies to apply UK SRS in addition to their home jurisdiction requirements would create duplicative disclosure obligations without proportionate benefit to UK investors3.

Most major jurisdictions are implementing ISSB-based sustainability standards that provide comparable disclosure to UK SRS.

Why UKLR 14, 15 get the flexible approach

The FCA's flexible approach for UKLR categories 14 and 153 reflects practical recognition that overseas companies often face mandatory sustainability disclosure in their home jurisdictions.

Requiring additional UK SRS compliance would create dual sustainability reporting obligations without clear benefit to UK market participants.

There is no requirement in CP26/5 for the overseas standards to be ISSB-aligned — the rule only requires the company to identify what it follows, or state that it follows nothing, and signpost where those disclosures can be found3.

The underlying IFRS S1 and S2 standards form the basis for UK SRS.

The UK government consulted on six proposed amendments in June 2025; the final Standards' differences from IFRS S1 and S2 are set out in Annex A of the government response, which carries no count.

Home jurisdiction alignment also supports global sustainability disclosure consistency.

As more jurisdictions implement ISSB-based standards, the flexible approach allows UK markets to benefit from this convergence while avoiding fragmentary disclosure requirements that complicate international capital allocation.

The disclose-home-jurisdiction statement

Companies applying the UKLR 14/15 flexible approach must provide a disclose-home-jurisdiction statement explaining their sustainability disclosure approach3.

The statement must identify the climate and sustainability disclosure requirements the company is subject to in its primary overseas listing location, signposting where those disclosures can be found; any standards voluntarily adopted; or — if neither applies — a statement that it is not subject to and does not voluntarily follow any such requirements (CP26/5 ¶9.4).

The requirement is one of signposting rather than comparison: it lets UK investors find the overseas or voluntary disclosures a company relies on, or know that none exist.

Companies should address: the overseas climate and sustainability disclosure requirements they are subject to, and where to find them; any standards voluntarily adopted; or, if neither applies, a statement to that effect.

CP26/5 ¶¶9.8–9.9 add a sustainability-assurance statement on the same footing as Chapter 7.

Scenario 2 — UK subsidiaries of overseas parents

UK subsidiaries of overseas parents are separate UK legal entities subject to UK corporate law4.

They may voluntarily adopt UK SRS S1 and/or S2 independently of their parent company's sustainability disclosure approach, and may become subject to mandatory UK SRS requirements if they fall within FCA CP26/5 scope or future MCR Strand 2 requirements.

Voluntary UK SRS adoption by UK subsidiaries supports several strategic objectives1: preparation for potential mandatory requirements, value chain readiness for UK customers, demonstration of UK market commitment, and integration with parent company's global sustainability strategy where the parent applies IFRS S1/S2.

UK subsidiaries in FCA CP26/5 scope (listed UK companies) would face the same proposed UK SRS requirements as UK-parented companies if the FCA's proposals are adopted3 — CP26/5 is not yet in force, and the FCA has not published a Policy Statement.

The overseas parent relationship does not exempt UK subsidiaries from UK sustainability disclosure obligations where they arise under UK law.

Group consolidation considerations

UK subsidiaries of overseas parents face group consolidation considerations where the parent prepares consolidated sustainability reporting under IFRS S1/S2 or equivalent standards8.

The UK subsidiary's UK SRS disclosure may need coordination with parent company sustainability reporting to ensure consistency and avoid duplication.

Best practice involves aligning UK subsidiary data collection and disclosure preparation with parent company sustainability reporting cycles where practical.

This coordination supports both UK SRS compliance and parent company consolidated reporting requirements while minimising duplication of effort.

Where UK subsidiaries represent material operations for the overseas parent, UK SRS adoption may actually support parent company compliance by providing high-quality sustainability data aligned with ISSB methodology2.

The UK government proposed six amendments to IFRS S1/S2 in June 2025; the final Standards' differences are set out in Annex A of the government response, which carries no count, and are technical refinements that do not fundamentally alter the underlying disclosure framework.

IFRS S1/S2 alignment with UK SRS

UK SRS S1 and S2 maintain close alignment with IFRS S1 and S21.

The UK government proposed six amendments in June 2025 to address UK regulatory integration and practical implementation considerations; the final Standards' differences from IFRS S1 and S2 are set out in Annex A of the government response, which carries no count.

This alignment facilitates coordination between UK subsidiary UK SRS application and overseas parent IFRS S1/S2 application.

The alignment enables UK subsidiaries to leverage parent company sustainability infrastructure, methodology, and expertise while meeting UK-specific requirements2.

Shared approaches to materiality assessment, scenario analysis, and metrics calculation reduce implementation complexity for multinational groups.

• Materiality methodology — UK SRS and IFRS S1/S2 share financial materiality approach, enabling consistent materiality assessment across group entities
• Scenario analysis framework — TCFD-based scenario analysis requirements align across UK SRS and IFRS S2, supporting shared modelling approaches
• GHG Protocol alignment — Both frameworks reference GHG Protocol Corporate Standard, enabling consistent emissions measurement methodology
• Assurance compatibility — ISSA (UK) 5000 aligns with international sustainability assurance standards, supporting group assurance strategies

Scenario 3 — UK branches of overseas companies

UK branches of overseas companies operate in the UK without separate UK incorporation and therefore sit outside UK SRS scope1.

UK SRS applies to UK companies and UK-listed entities, not to overseas companies operating through UK branch structures.

The branch vs subsidiary distinction is critical for UK SRS application4.

Subsidiaries are separate UK legal entities subject to UK corporate law and potentially UK SRS requirements.

Branches are extensions of overseas companies operating in the UK but remaining subject to their home jurisdiction corporate law framework.

However, UK branches may be subject to other UK sustainability disclosure obligations7.

SECR requirements can apply to UK operations of overseas companies if those operations meet the SI 2018/1155 thresholds on a UK operations basis, regardless of the overseas company's overall size or structure.

Branch vs subsidiary distinction

The branch vs subsidiary distinction determines UK regulatory treatment including UK SRS application4.

Subsidiaries are separate legal persons incorporated under UK law.

Branches are business operations of overseas companies without separate legal personality in the UK.

Key indicators of subsidiary status include: separate UK incorporation under Companies Act 2006; separate UK company registration number; independent board of directors; separate financial statements filed with Companies House; and ability to enter contracts in its own name.

Key indicators of branch status include: operation under overseas company registration; reliance on overseas company board governance; financial results consolidated into overseas company accounts; contracts entered in overseas company name; and UK operations managed as division of overseas entity.

SECR considerations for overseas-parented entities

SECR requirements under SI 2018/11557 can apply to both UK subsidiaries of overseas parents and UK branches of overseas companies if they meet threshold tests on a UK operations basis.

SECR application depends on UK entity size and status rather than overseas parent characteristics.

For UK subsidiaries, SECR qualification follows the standard two-of-three threshold test applied to the UK subsidiary's own financial results and employment.

The overseas parent's size does not affect UK subsidiary SECR qualification — only the subsidiary's standalone UK financial position matters.

For UK branches, SECR application is more complex and depends on the overseas company's overall size and its UK operations meeting SI 2018/1155 criteria7.

The Environment Agency and Companies House guidance should be consulted for branch-specific SECR application, as this involves specialist regulatory interpretation.

Practical guidance by scenario

Scenario 1 (UKLR 14/15 secondary listing): Engage both UK and home jurisdiction advisers to prepare the proposed signposting statement.

There is no UK SRS comparison or ISSB-alignment requirement to satisfy — identify what overseas or voluntary standards are followed, or confirm none are.

Monitor for the FCA's Policy Statement (expected autumn 2026), since CP26/5's proposals for UKLR 14 and 15 are not yet in force.

Scenario 2 (UK subsidiaries): Consider voluntary UK SRS adoption for value chain readiness and preparation for potential MCR Strand 2 mandatory requirements.

Coordinate with overseas parent sustainability strategy where parent applies IFRS S1/S2.

Leverage shared group methodology and expertise while addressing UK-specific requirements.

Scenario 3 (UK branches): Confirm branch vs subsidiary status through legal analysis.

Assess SECR application to UK operations.

Consider whether overseas parent's global sustainability disclosure addresses UK stakeholder requirements or whether additional UK-focused voluntary disclosure would support UK operations.
