Good to know
How long does it take? How long an installation takes depends on the system and the property.
Do I need one? The Boiler Upgrade Scheme is for eligible properties in England and Wales; it is not a UK-wide grant and the current GOV.UK eligibility page lists no EPC prerequisite.
Before you book, read how to check a heating engineer is registered.
How to pay less
- Use an MCS-certified installer where a grant requires it
- Ask for radiator, pipework, insulation, electrical, and grant assumptions to be itemised
