Air Source Heat Pump Installers - BUS Scheme

The RHI and Green Homes Grant schemes have both been closed and are no longer available to new applicants.
The new scheme is called the BUS Scheme to encourage the installation of renewable technologies. The BUS scheme stands for the Boiler Upgrade Scheme.


The Department for Business, Energy and Industrial Strategy (BEIS) and Ofgem have launched the Boiler Upgrade Scheme (BUS).

Contractors are now able to make voucher and redemption applications. Please note that – although the voucher application system opened on 23 May 2022 – installations commissioned from 1 April 2022 will be eligible to apply for the BUS.

To apply for a Boiler Upgrade Scheme grant, contractors will need to set-up a BUS installer account. Applications can then be submitted to Ofgem, more information is at the bottom of this page.

What is the Boiler Upgrade Scheme?

A new, flat, upfront grant, the Boiler Upgrade Scheme comprises £450million of total support over a three-year period.

Announced in the government’s Heat and Buildings Strategy, the BUS follows the Domestic Renewable Heating Incentive (DRHI), which closed at midnight on 31 March 2022.

The BUS allows consumers to apply for a one-off grant payment of:

£5,000 towards the cost of an air-source heat pump (ASHP) or biomass installation
or £6,000 towards the cost of a ground-source heat pump (GSHP) installation.
Please be aware that biomass installations are only supported in limited circumstances, and solar thermal is excluded from the scheme.

Contractors will be required to lead the voucher application on behalf of the consumer.

Homes and small non-domestic buildings on and off the gas grid, including owner-occupiers, private landlords and custom-builds, are eligible for the BUS. New buildings and social housing will not be eligible for support. The consumer must have an EPC issued within the last 10 years to qualify.

Grants are capped at a total budget of £150 million per year over the next three years.
