The Boiler Upgrade Scheme sits within the government’s broader Warm Homes Plan, which focuses on lowering energy costs, improving home comfort and cutting carbon emissions across England.
With energy bills continuing to impact households and the UK accelerating its shift away from fossil fuels, many homeowners are considering cleaner, more energy-efficient heating solutions.
The Boiler Upgrade Scheme (BUS) helps make that switch more affordable — and HEART is on hand to guide you through every stage of the journey.
What Is the Boiler Upgrade Scheme?
The Boiler Upgrade Scheme (BUS) is a government-funded grant available to property owners in England and Wales. It offers upfront financial support to replace existing fossil-fuel systems, such as gas or oil boilers, with low-carbon alternatives — mainly heat pumps.
The funding is deducted at installation, reducing your initial outlay. Approved installers like HEART handle the grant application on your behalf and subtract the award directly from your quote, ensuring a simple and transparent process.
What Funding Is Available?
Through the Boiler Upgrade Scheme, eligible properties can receive:
£7,500 grant for:
- Air Source Heat Pumps (ASHPs)
- Ground Source Heat Pumps (GSHPs)
£5,000 grant for:
- Biomass boilers
(generally available for rural, off-gas-grid homes)
The new system must be designed to deliver full space heating and hot water for the property, ensuring dependable, long-term performance and efficiency.
Who Can Apply for the Boiler Upgrade Scheme?
The scheme is open to a variety of property owners, provided the criteria are met:
- Location: Homes and small non-domestic buildings in England and Wales
- Property type: Owner-occupied properties, private landlords and small businesses
- Current system: An existing fossil-fuel boiler (gas, oil or LPG)
- Replacement: An eligible low-carbon heating system providing whole-home heating and hot water
