Free ESOS Phase 4 budget screen
What will ESOS Phase 4 cost you?
Answer about 15 questions about your organisation and sites. We estimate your Energy Savings Opportunity Scheme (ESOS) Phase 4 programme: whether you qualify, which buildings need an audit, and a price for the whole programme. An ESOS Lead Assessor checks every screen before we send it.
What you get
One price for the whole programme.
Your screen sets out a Lead Assessor fee and a fixed price for each building audited, so you can budget for the total now. The sampling plan confirms it, and it moves only by the published price of each building added or removed.
