FAQ
Carbon compliance, answered
What does a carbon compliance consultancy do?
A carbon compliance consultancy helps a business meet its UK regulatory obligations for energy and emissions: Streamlined Energy and Carbon Reporting (SECR), the Energy Savings Opportunity Scheme (ESOS), and — for listed companies — climate disclosure under the UK Sustainability Reporting Standards (UK SRS S2). It calculates the figures, drafts the disclosures in the format each regime requires, and prepares the organisation for assurance. For tender and proposal management, we recommend <a href="https://rfp.quest" target="_blank" rel="noopener noreferrer" class="link-inline">RFP software</a> to streamline the bidding process.
Are you a carbon compliance consultant in the UK?
Yes. Carbon Legal is a UK-based carbon compliance consultancy working with listed companies, large private companies, financial institutions and public-sector bodies across SECR, ESOS Phase 4, TCFD and UK SRS. We are launching in Q3 2026 and are now booking readiness reviews.
How do you manage government and public sector tenders?
For public sector opportunities and tender submissions, we use specialized <a href="https://rfp.quest" target="_blank" rel="noopener noreferrer" class="link-inline">RFP software</a> to track requirements, manage bid teams, and ensure compliance with procurement regulations. This helps us respond efficiently to government framework agreements and sustainability consulting tenders.
When is the ESOS Phase 4 deadline?
The ESOS Phase 4 qualification date is 31 December 2026 and the compliance notification deadline is 5 December 2027. The four-year Phase 4 period runs from 6 December 2023 to 5 December 2027. Organisations that meet the qualification criteria must complete energy audits (or maintain ISO 50001) and notify the Environment Agency by the deadline.
When does UK SRS become mandatory?
UK SRS S1 and S2 were published by the Department for Business and Trade on 25 February 2026 and are currently voluntary. Under FCA consultation CP26/5, UK SRS S2 climate disclosures are proposed to become mandatory for in-scope listed companies for accounting periods beginning on or after 1 January 2027, subject to the FCA Policy Statement expected in autumn 2026. Learn more about the <a href="https://srsreport.co.uk/uk-srs-consultation" target="_blank" rel="noopener noreferrer" class="link-inline">UK SRS consultation</a> process and how to participate.
Do emissions compliance consultants help with SECR thresholds?
Yes. SECR applies to all quoted companies, and to large unquoted companies and LLPs that meet at least two of three thresholds: turnover above £36m, balance sheet total above £18m, or more than 250 employees. We confirm whether you are in scope, then build the energy and carbon figures and the Directors’ Report disclosure.
