A government initiative in England and Wales to help households replace fossil-fuel heating with low-carbon technologies, including air source heat pumps, through installer-led grants.
The Boiler Upgrade Scheme offers a fixed grant toward the cost of installing an eligible low-carbon heating system in place of an oil, gas, or other fossil-fuel boiler (subject to property and technology rules). The process is usually handled by your MCS-certified installer, who applies for a voucher on your behalf and redeems it after the work is completed to your satisfaction.
Grant amounts, caps, and eligibility are decided by the UK government and Ofgem’s scheme rules, not by Energy Badger. We summarise BUS here to help you understand the landscape; always confirm current terms with your installer and on GOV.UK before you commit.
Heat loss, emitters, and hot water are assessed so the system is sized correctly, BUS is about eligible kit installed to standard, not a generic online price.
An MCS-registered installer quotes the job and, if you proceed, applies for a BUS voucher for your eligible installation within scheme limits.
After commissioning and certification, the installer redeems the voucher; the grant reduces what you pay compared with the same job without BUS.
We explain whether a heat pump suits your home, what upgrades might be needed, and how grants like BUS could affect your quote, then we handle clear proposals and honest timelines. We’ll tell you what evidence and registrations matter so you’re not surprised at voucher stage.
