Boiler Upgrade Scheme: current 2026 amounts and rules
Last verified:
The Boiler Upgrade Scheme gives an upfront voucher towards eligible low-carbon heating in England and Wales. An MCS-certified installer checks the property, quotes with the voucher deducted and applies to Ofgem. It is not a free-boiler scheme.
Current voucher amounts
A valid EPC is no longer required for applications made from 28 April 2026. Other property and technology rules still apply.
How it works
- Contact an MCS installer — the property owner requests a technical assessment and quote
- Installer checks and applies — the installer applies to Ofgem if the project meets the rules
- Confirm the balance — the property owner pays any amount not covered by the voucher
Frequently asked questions

Is an EPC still required?
No valid EPC is required for applications made from 28 April 2026, according to current Ofgem guidance.
Who applies?
An MCS-certified installer applies on behalf of the property owner.
