Carbon Reporting and Compliance is the single retainer behind everything UK businesses must file.
SECR (Streamlined Energy and Carbon Reporting) requires UK companies above the threshold to file Scope 1 and Scope 2 emissions, an intensity ratio, and a narrative on energy-efficiency action inside their statutory accounts every year. We collate the meter data (gas, electricity, on-site fuel), apply the latest DEFRA conversion factors, draft the narrative, and hand finance an audit-ready section ready to drop into the directors' report. The whole process runs alongside Purely Insights so the underlying consumption data is the same data that finance sees in monthly reporting.
ESOS (Energy Savings Opportunity Scheme) Phase 4 lands in 2027 and the qualification thresholds catch any large company or large group: 250+ employees, or turnover above £44m and balance sheet above £38m. We cover the full audit cycle: site selection, energy review, lead-assessor sign-off, EA notification, and the four-year record. Where ESOS audits surface no-regret saving actions, we put the procurement and project-management capacity around delivering them.
Carbon Accounting is the umbrella that sits behind both SECR and ESOS. We build a Scope 1 + 2 + 3 inventory to the GHG Protocol Corporate Standard, tag every emissions source so it can be re-cut for CDP, B-Corp, EcoVadis, or investor diligence, and run year-on-year comparisons that survive an audit. For clients with science-based or net-zero commitments, we model the trajectory from baseline year to target year against SBTi guidance.
Allowance procurement is no longer part of this retainer: it now runs as its own fully online journey at /carbon-allowances, digital end to end with lean execution costs. Live prices for both markets sit at /tools/carbon/uk-ets and /tools/carbon/eu-ets so you can see today's levels before you start an order.

Real-world use cases
Scenarios from the Purely Energy book of business.
| Customer profile | Scenario | Outcome with Carbon Reporting and Compliance |
|---|---|---|
| Manufacturing group, 8 sites, FY March year-end | Newly above the SECR threshold after acquisition, never filed before. Auditors flagged it 6 weeks before sign-off. | SECR section drafted in 4 weeks, slotted into the directors' report on time. Re-engagement booked for Q3 ESOS Phase 4 prep, allowance position reviewed alongside. |
| B-Corp tech firm, 240 employees, 4 offices | Recertification audit needed Scope 3 inventory and a Science Based Targets initiative trajectory. | Scope 3 inventory built across 8 categories, SBTi 1.5C trajectory modelled to 2030, B-Corp pack delivered on schedule. CDP A-list submission used the same evidence. |
| Multi-academy trust, 22 schools | Trustees wanted ESOS qualification check, plus a credible plan to offset residual gas through GOO-backed biomethane and voluntary EUA retirement. | Trust qualified for ESOS Phase 4, audit programme scoped for FY 2027. Combined GOO-backed gas and 1,400 EUA voluntary retirement secured the trustees' carbon-neutral position. |
Frequently asked questions
Who has to file SECR and what's the threshold?
Quoted companies, large unquoted companies, and large LLPs. Large means meeting any two of: turnover above £36m, balance sheet above £18m, or 250+ employees. The Scope 1 + 2 disclosure goes inside the directors' report. We handle the threshold check and the filing in the same engagement.
What is ESOS Phase 4 and when is it due?
ESOS is the UK's mandatory energy-audit scheme for large companies. Phase 4 covers the qualification snapshot at 31 December 2026 and the compliance deadline is 5 December 2027. We cover qualification, audit, lead-assessor sign-off, and the Environment Agency notification through MESOS.
Does Purely Energy provide the lead assessor or do we need to hire one separately?
We provide the lead assessor in-house, registered with an Environment-Agency-recognised body. There is no separate appointment fee and no scheduling gap between the audit work and the sign-off.
What's the difference between location-based and market-based Scope 2?
Location-based uses the average grid emissions factor for where you consume. Market-based uses the contractual instruments you have actually purchased: REGOs in the UK, GOOs for biomethane, PPAs, supplier-specific fuel mixes. REGO-backed electricity allows market-based Scope 2 to be reported as zero, which is why most ESG-led buyers also take Green Energy from us at the same time.
How is the price quoted?
Carbon Reporting and Compliance is sold as an annual retainer, scoped during a year-zero discovery and held flat thereafter unless your portfolio changes materially. UKA and EUA procurement is priced separately through the fully online journey at /carbon-allowances, quote to execution without a phone call. Energy supply is quoted as usual on the products pages; nothing is bundled or hidden.
Do you stay involved between annual filings?
Yes. The retainer covers monthly progress against the carbon trajectory, surrender-deadline alerts before April 30 each year, refreshed forecasts when policy changes, and quarterly reviews with finance and ESG stakeholders. SECR and ESOS filings are the public artefacts, but the year-round work is what lets them be filed quickly and confidently.
Can you handle CDP, B-Corp, EcoVadis, and CSRD as well?
Yes. The underlying GHG Protocol inventory is built so it can be re-cut for any of these frameworks without rebuilding the data model each time. CDP and B-Corp are the most common asks; CSRD is becoming more frequent for UK groups with EU subsidiaries.
