Simple checker
Answer a few questions about your organisation on the Phase 4 qualification date (31 December 2026). Indicative only — edge cases (recent growth/shrink, overseas structures) need the full GOV.UK guidance.
If you may need ESOS
- Book the £19 guided scope check (email us to start).
- If you are likely in scope, ask for the first three months discount on Essential or Premium when you subscribe.
- Read the official guidance on GOV.UK — Energy Savings Opportunity Scheme.
- Ask us for an introduction to a qualified ESOS partner — we do not carry out the assessment ourselves.
