What is a carbon legislation readiness check?
A carbon legislation readiness check is a systematic assessment of your organisation's preparedness for UK carbon and energy reporting requirements.
The UK has multiple overlapping carbon compliance regimes — SECR1, ESOS2, TCFD, and the new UK SRS3 — each with different thresholds, deadlines and penalties.
The UK Government's Environmental Reporting Guidelines require every carbon legislation readiness check to assess all applicable regimes.
This carbon legislation readiness check identifies which regimes apply to you, what you need to do, and by when, and the wider sustainability reporting standards reference covers each regime in depth.
SECR carbon legislation readiness check
Streamlined Energy and Carbon Reporting (SECR) requires annual energy and emissions disclosure in your Directors' Report as part of your carbon legislation readiness check.
The Department for Education's SECR guidance provides detailed requirements for your carbon legislation readiness check.
If you answer "Yes" to the first two items, SECR applies to your next financial year.
Our SECR compliance specialists help with the full reporting cycle.
ESOS Phase 4 carbon legislation readiness check
ESOS Phase 4 requires large undertakings to conduct energy audits by 5 December 2027 — a critical element of your carbon legislation readiness check.
The Environment Agency's ESOS compliance guide outlines qualification criteria.
The qualification date is 31 December 2026 — if you qualify then, you must comply by 5 December 2027.
Our ESOS consultants provide lead-assessor-supported audits.
UK SRS carbon legislation readiness check
The UK sustainability reporting standards are voluntary today for any entity.
The FCA has proposed mandatory climate disclosures for in-scope listed companies from 1 January 2027, but has published no Policy Statement and announced no confirmed date.
Under FCA CP26/5, UK SRS S2 climate disclosures are proposed to be mandatory from 1 January 2027.
Our UK SRS compliance team helps with the transition from TCFD.
Carbon reduction plan legislation readiness check
Carbon Reduction Plans are required for government contracts over £5m per year under PPN 0065.
Suppliers who bid for public contracts regularly tend to keep the plan in the same library as the rest of their bid content — most tender response software handles this — so the version a buyer sees is always the current one.
Ownership has moved too.
Carbon figures now sit beside the accounts, so the CFO is usually the person who signs them off — and companies without one often hire a fractional CFO for the first reporting cycle.
How the business then talks about its carbon position is a positioning decision as much as a compliance one, which is where a go-to-market strategy agency earns its fee.
| Check item | Your status |
|---|---|
| Bid for government contracts? | ☐ Yes / ☐ No |
| Contract value £5m+ per year? | ☐ Yes / ☐ No |
| Baseline emissions calculated? | ☐ Yes / ☐ No |
| Net zero commitment by 2050? | ☐ Yes / ☐ No |

PPN 006 applies to procurements advertised from 24 February 2025.
Our net zero consultants prepare compliant carbon reduction plans.

Frequently asked questions
What is a carbon legislation readiness check?
A carbon legislation readiness check assesses whether your organisation is prepared for UK carbon and energy reporting requirements. It reviews your compliance with SECR, ESOS Phase 4, TCFD, UK SRS and carbon reduction plan obligations, identifying gaps and priorities before deadlines.
Who needs a carbon legislation readiness check?
Any UK business that might qualify for carbon reporting should conduct a readiness check. This includes quoted companies (SECR), large unquoted companies and LLPs (SECR if meeting thresholds), large undertakings (ESOS), listed companies (UK SRS proposed from 2027, not yet confirmed), and businesses bidding for government contracts over £5m per year (PPN 006).
How often should I check carbon legislation readiness?
Check your carbon legislation readiness annually and whenever there are significant business changes — growth past thresholds, acquisitions, new government contracts, or regulatory updates. With UK SRS proposed to become mandatory from 2027 (subject to the FCA Policy Statement expected in autumn 2026) and the ESOS Phase 4 qualifying date on 31 December 2026, regular checks are essential.
What happens if I fail a carbon compliance check?
Failing to meet carbon legislation requirements can result in fines, prosecution, exclusion from government contracts, and reputational damage. SECR creates no penalty of its own; non-compliance is caught by the general Companies Act directors’-report offences and the FRC’s court-declaration powers. ESOS failures can incur civil penalties up to £90,000, and missing PPN 006 requirements disqualifies you from major government tenders.
Can Carbon Legal help with compliance gaps?
Yes. After your carbon legislation readiness check, Carbon Legal provides the specific compliance support you need — SECR reporting, ESOS Phase 4 audits, UK SRS preparation, and carbon reduction plans. We launch in Q3 2026 and are booking readiness reviews now.
