Boiler Upgrade Scheme Grants of up to £9,000
Eligible property owners in England and Wales can receive £7,500 towards an air-to-water or ground source heat pump. A temporary £9,000 grant is available for qualifying off-gas-grid properties replacing oil or LPG, for applications properly made from 21 July 2026 to 31 March 2027. Eligible residential air-to-air heat pumps can receive £2,500.
As an MCS-certified installer, Green Energy Homes can assess your project, apply for the Boiler Upgrade Scheme on your behalf and deduct the approved grant from your quote.
Making low-carbon heating more affordable
The Boiler Upgrade Scheme (BUS) is a government scheme that reduces the upfront cost of installing eligible low-carbon heating in homes and non-domestic properties across England and Wales. It supports air-to-water, air-to-air and ground source heat pumps, as well as biomass boilers in limited circumstances.
BUS is installer-led, which means you do not apply to Ofgem yourself. Your MCS-certified installer assesses the proposed project, submits the application and claims the grant after the eligible installation has been completed. The approved grant must be shown as an upfront deduction on your quote and invoice.
Green Energy Homes will explain which grant may apply, prepare a clear quotation and manage the application process. Final eligibility is determined by Ofgem under the scheme rules.
Current Boiler Upgrade Scheme grants
The amount available depends on the technology, the property and, for the temporary uplift, the heating system being replaced.
| Eligible installation | BUS grant | Important qualification |
| Air-to-water heat pump | £7,500 | £9,000 where an eligible off-gas-grid property replaces oil or LPG during the temporary uplift. |
| Ground source heat pump | £7,500 | £9,000 under the same off-gas-grid oil or LPG conditions. Eligible water-source systems fall within the ground source category. |
| Air-to-air heat pump | £2,500 | Residential properties only. The temporary £9,000 uplift does not apply. |
| Biomass boiler | £5,000 | Available only in limited rural, off-gas-grid circumstances and subject to additional scheme requirements. |
Grant values and eligibility are subject to current scheme rules and Ofgem approval.
Important: the £9,000 grant is not a general increase
It applies only where an eligible property is off the gas grid and replaces oil or LPG heating with an air-to-water or ground source heat pump. Off-grid properties replacing coal, direct electric heating or a fossil-fuel hybrid do not receive the uplift, although the standard £7,500 grant may still be available. Self-build properties cannot receive the £9,000 uplift.

Could you qualify for the temporary £9,000 grant?
Your project may qualify for the higher grant if all of the following apply:
- The property is in England or Wales.
- The property is not connected to the gas grid.
- Its existing heating system is fuelled by oil or liquefied petroleum gas (LPG).
- The new system will be an eligible air-to-water or ground source heat pump.
- The application is properly made between 21 July 2026 and 31 March 2027.
- The property is not a self-build and meets all other BUS requirements.
What does ‘properly made’ mean?
Ofgem must have the information required to assess the application, together with the property owner’s consent and identity verification. Requesting a quote or beginning the process before the deadline is not enough on its own, so allow time for the application to be completed.
Spread the remaining cost with flexible finance
After the BUS grant has been deducted, eligible customers may choose to spread the remaining balance through our finance partner. Finance is optional and separate from the grant application, allowing you to compare the available terms with paying from savings or another source.
