🇬🇧 UK SRS: Is your reporting ready for the 2027 reality check?
What the New Rules Mean for UK Companies
The UK is preparing for its biggest ESG shift since TCFD. By 2027, the new UK Sustainability Reporting Standards (UK SRS) will become the mandatory framework for listed companies.
Based directly on the global IFRS S1 and S2 standards, the UK is aligning with international environmental reporting standards. The SRS aim to ensure your business is financially resilient in a changing climate.
🔍 What is changing?
Everyone is now moving toward a single standard
Mandatory Scope 3: Value-chain reporting becomes mandatory in Year 2 of your reporting.
Global portability: Your UK reports will finally be comparable with international financial markets.
Beyond carbon: You must now disclose climate-related risks, strategy, and financial resilience.
Phased roadmap: Listed companies report on Scopes 1 and 2 in 2027, with Scope 3 following in 2028.
👤 Who is affected?
The UK SRS will apply to UK-listed companies in the following categories:
Commercial companies (UKLR 6) & secondary listings (UKLR 14)
Depositary receipts (UKLR 15)
Non-equity & non-voting equity shares (UKLR 16)
Transition category (UKLR 22)
📅 The compliance timeline
Here are the dates to circle in your calendar:
February 2026: Final UK SRS standards published by the UK Government.
January 2027: Official start for mandatory reporting (for the 2027 fiscal year).
Early 2028: First formal UK SRS reports must be published.
Year 2 (2028): Scope 3 reporting becomes mandatory for all in-scope firms.
🔥 Challenges vs. opportunities
The Scope 3 hurdle: Collecting Scope 3 data is a marathon, not a sprint. Delaying this process is the biggest risk to compliance, as it requires deep coordination with suppliers and detailed data analysis.
The reward: By adopting these standards, companies have a tangible opportunity to move sustainability from a “marketing cost” to a core business driver. Robust ESG data builds investor confidence and helps you identify operational inefficiencies before they become liabilities.
