What is the Boiler Upgrade Scheme (BUS)?
The government boiler upgrade scheme was launched in April 2022. It will provide a boiler upgrade grant to help owners of domestic and small non-domestic properties in England or Wales with the upfront cost of installing low carbon heating systems, such as heat pumps.
The scheme will provide:
- £7,500 towards an air source heat pump or a ground source heat pump
- £5,000 towards a biomass boiler
- £2,500 towards an air-to-air heat pump
The grant will only cover biomass boilers in rural locations and in properties that are not connected to the gas grid. A temporary uplift of £1,500 for air source heat pumps at off-grid properties or those heated by LPG or natural gas, resulting in a total grant figure of £9,000 for eligible properties.
How does BUS work?
You must be MCS certified for your customer to be eligible for the BUS grant. You will need to apply for the grant on behalf of your customer and then deduct the value of the grant off the price they pay.
- Check your customer’s installation is eligible for the BUS on the government website and let them know.
- Provide a quote and agree a price for the installation.
- You, the installer, then applies for the grant.
- Ofgem will contact your customer to confirm that you are acting on their behalf.
- When the installation has been completed, you will take the amount of the grant off the price your customer pays
