ESOS Phase 4 qualification checker
Find out whether your organisation must comply with ESOS Phase 4 by the 5 December 2027 deadline. Qualification is assessed on 31 December 2026.
The Phase 4 thresholds
An organisation qualifies for the Energy Savings Opportunity Scheme if, on the qualification date of 31 December 2026, it employs 250 or more people in the UK, OR has an annual turnover above £44 million and a balance sheet total above £38 million. Group structures inherit qualification from a qualifying parent.
Qualifying organisations must commission an energy audit covering at least 95% of total energy consumption, signed off by an approved Lead Assessor, and submit a notification to the Environment Agency by 5 December 2027.
Send us one bill. We'll send back every overcharge — and the cheapest legitimate replacement.
Whether you run a Mayfair restaurant group or rent a flat in Salford, the audit is the same and the fee is the same: nothing, unless we save you money.
