FCA consultation is expected in 2025, with mandatory reporting likely beginning for accounting periods starting on or after 1 January 2026 for listed companies. Large private companies may follow 1-2 years later through Companies Act amendments.
Initially, both will coexist. SECR remains statutory under the Companies Act while UK SRS will be implemented through FCA rules. Eventually, we expect either SECR to be amended to align with UK SRS or replaced entirely to avoid duplication.
SMEs are not expected to be directly mandated initially. However, supply chain pressure from larger companies reporting under UK SRS will likely require SMEs to provide sustainability data. Voluntary adoption may also benefit SMEs seeking investment or contracts.
