Boiler Upgrade Scheme basics for homes in England

The Boiler Upgrade Scheme can reduce the upfront cost of eligible low-carbon heating in England, but an MCS-certified installer applies and Ofgem confirms the current conditions.

Who applies and who decides eligibility?

The scheme is installer-led: an MCS-certified installer applies for a voucher for the property, and Ofgem administers the scheme. Broad conditions include ownership and replacing an eligible existing heating system, but property, technology, previous funding and commissioning rules also apply.

Why are grant amounts not repeated here?

Grant categories and values can change, including time-limited or fuel-specific differences. Use the linked GOV.UK eligibility journey and current Ofgem property-owner guidance for the amount and conditions that apply when the application is properly made. A quote should show the grant as an upfront discount where applicable.

What should you verify before relying on funding?

Confirm that the installer and proposed system meet current MCS and scheme requirements, that the property and replaced system qualify, and that any application timetable is realistic. Do not sign a contract on the assumption that this summary guarantees a voucher. This page is reviewed quarterly and on known scheme changes.
