The Boiler Upgrade Scheme (BUS) is currently one of the most effective ways to lower the upfront cost of switching to low-carbon heating. As of 2026, the scheme remains a primary driver for the UK’s transition to net-zero.
Here is the essential breakdown of how it works for an Air Source Heat Pump (ASHP).
£7,500: This is the fixed grant for an air-to-water heat pump.
Direct Discount: You don’t “apply” and wait for a check; the installer applies for the voucher and deducts it directly from your quote. You only pay the remaining balance.
The scheme is “installer-led,” meaning they do the heavy lifting:
Get Quotes: Find an MCS-certified contractor. They will survey your home to ensure a heat pump is viable.
The Voucher: Once you agree on a quote, the installer applies to Ofgem for the BUS voucher.
Confirmation: You will receive an email from Ofgem to confirm you’ve given the installer permission to act on your behalf.
Installation: The installer has 3 months from the voucher issue date to complete the ASHP installation.
Payment: The installer redeems the voucher and receives the £7,500 directly from the government
