Summary
The Boiler Upgrade Scheme provides grants to encourage property owners to replace existing fossil fuel heating with more efficient, low carbon heating systems including air source heat pumps, ground source heat pumps and, in limited circumstances, biomass boilers.You can get:
£7,500 off the cost and installation of an air source heat pump
£7,500 off the cost and installation of a ground source heat pump
£5,000 off the cost and installation of a biomass boiler
These grants help property owners overcome the upfront cost of installing a low carbon heating system.
Eligibility
your property must be a home or small non-domestic building in England or Wales. The maximum installation capacity of 45kWth covers the vast majority of these properties.
your property must have a valid energy performance certificate with no outstanding recommendations for loft or cavity wall insulation. (There are some exceptions to this, please speak to your installer for further information).
the commissioning date of your low carbon heating system must be on or after 1 April 2022.
biomass boilers are only eligible in properties that are both in a rural location and not connected to the gas grid. Heat pumps do not have either of these restrictions.
you must be fully replacing an existing fossil fuel system such as an oil or gas boiler, or an electric heating system such as storage or panel heaters. Funding will not be available for the replacement of existing low carbon heat systems.
the installation cannot be funded by more than one source of public funds and you cannot apply if you have already been given government funding or support for a heat pump or biomass boiler.
you can still apply if you’ve received separate funding for energy efficiency upgrades such as insulation, doors or windows.
new-build homes and social housing are not eligible for the Boiler Upgrade Scheme, although self-build properties are eligible.
Objectives
The aim of this scheme is to incentivise and increase the deployment of low carbon heating. This scheme is part of a wider package of policies we are introducing to scale up heat pump deployment and support industry to reduce the costs of heat pumps.
Dates
Low heating systems commissioned on or after 1 April 2022 could be eligible for support from the scheme.From 23 October 2023, the grant levels for heat pumps were increased to £7,500.Funding is confirmed until 31 March 2028.
How to apply
The application is installer-led, with the installer applying for the grant on the property owner’s behalf. Your chosen installer will need to be certified by the Microgeneration Certification Scheme (MCS), a nationally recognised standards organisation that gives you assurance of the quality of your product and competence of your installer. It also ensures that your installer complies with high consumer protection standards.Your chosen installer will:
