UK SRS Thresholds — Company Qualification & Application Criteria

The UK Sustainability Reporting Standards (UK SRS) apply to Public Interest Entities (PIEs) based on specific size and listing criteria. Understanding these thresholds is essential for determining your compliance obligations and implementation timeline.

Listed Company Qualification

UK-listed companies automatically qualify for UK SRS reporting regardless of their size. This includes all companies with equity securities admitted to trading on a UK regulated market, specifically:

• London Stock Exchange Main Market listings — All premium and standard listed companies
• AIM listings with additional criteria — Subject to ongoing FCA consultation 4
• Specialist segments — Including infrastructure and investment trusts meeting PIE definitions
• Dual-listed entities — Where UK is the primary listing venue

Listed companies must begin UK SRS reporting for financial years starting on or after 1 January 2026, beginning with enhanced climate disclosures under UK SRS S2. Full sustainability disclosures under UK SRS S1 follow in 2027.

Large Private Company Thresholds

Large private companies qualify for UK SRS when they meet at least two of the following three criteria for two consecutive financial years: 2

Threshold Calculation Methodology

Employee Count Calculation

The 500-employee threshold uses specific calculation rules aligned with Companies Act 2006 definitions: 2

• Full-time equivalent basis — Part-time employees counted proportionally
• Average during financial year — Monthly or quarterly averaging acceptable
• Include all employment types — Permanent, fixed-term, and integrated temporary workers
• Group consolidation — Aggregate across all subsidiaries within consolidation scope
• Two-year test — Must exceed threshold in both current and previous financial years

Financial Threshold Measurement

Turnover and balance sheet thresholds follow established company law definitions:

• Net turnover — Revenue after VAT, returns, and trade discounts
• Gross assets — Total balance sheet value before depreciation and provisions
• Consolidated figures — Use group consolidated accounts where applicable
• Currency conversion — Use average exchange rates for foreign subsidiaries

Group Company & Subsidiary Considerations

UK SRS applies group-level assessment principles to prevent artificial fragmentation and ensure comprehensive reporting:

Parent Company Obligations

• Ultimate UK parent responsible for group-wide UK SRS reporting
• Consolidation scope follows same principles as financial statement consolidation
• Overseas subsidiaries included where material to UK group operations
• Joint ventures apply proportionate consolidation consistent with financial reporting

Subsidiary Exemptions

Qualifying subsidiaries may claim exemption from separate UK SRS reporting where:

• Included within parent company UK SRS reporting scope
• Parent company explicitly confirms subsidiary coverage in disclosures
• No conflicting materiality assessments between parent and subsidiary operations
• Subsidiary board formally acknowledges exemption reliance

International Framework Comparison

UK SRS thresholds align closely with international frameworks, particularly the EU Corporate Sustainability Reporting Directive (CSRD). This alignment facilitates compliance for multinational groups: 3

The alignment with EU CSRD criteria enables companies operating in both jurisdictions to leverage similar threshold assessments and data collection processes. However, disclosure requirements and assurance standards may differ between frameworks. See our detailed comparison guide for comprehensive analysis.

Implementation Phases & Timeline

UK SRS implementation follows a phased approach to allow companies adequate preparation time: 5

Preparation Timeline Recommendations

Companies should begin preparation well before their applicable phase:

• 18 months before — Complete materiality assessment and gap analysis
• 12 months before — Implement data collection systems and governance processes
• 6 months before — Engage assurance providers and conduct dry-run reporting
• 3 months before — Finalise disclosure templates and internal review processes

First-Time Application Guidance

Companies qualifying for UK SRS for the first time receive specific accommodation and guidance to support initial implementation:

Initial Year Accommodations

• Baseline establishment — May designate first reporting year as baseline for future comparisons
• Data limitations disclosure — Can explicitly state data availability constraints and improvement plans
• Materiality assessment — Complete double materiality assessment required but may be refined in subsequent years
• Assurance phase-in — May apply for modified assurance requirements during transition period

Preparation Recommendations

First-time applicants should prioritise these preparation activities:

• Materiality assessment — Engage stakeholders to identify material sustainability topics
• Data mapping exercise — Catalogue available sustainability data and identify gaps
• Governance establishment — Create sustainability committee and reporting responsibilities
• External expertise — Consider engaging sustainability consultants and assurance providers

Future Threshold Changes & Consultations

The government maintains flexibility to adjust thresholds based on implementation experience and international developments:

Ongoing Consultation Areas

• Large private company scope — Final thresholds and phase 3 implementation timeline
• AIM-listed companies — Specific criteria for Alternative Investment Market listings
• SME accommodation — Potential simplified reporting for smaller qualifying companies
• International alignment — Ongoing coordination with EU, US, and other frameworks

Monitoring and Review Schedule

The Department for Business and Trade has committed to regular review of threshold effectiveness:

• Annual monitoring — Track companies entering and exiting scope
• Three-year formal review — Comprehensive assessment of threshold impacts
• International coordination — Align with EU CSRD reviews and global standard development
• Stakeholder consultation — Regular engagement with business groups and professional bodies
