Changes have been made to the Boiler Upgrade Scheme, which are intended to make heat pumps cheaper and easier for families to install.
The scheme offers grants of £7,500 off the cost of heat pump installation.
Homeowners are set to have more choice over how they improve their home and will no longer have to install cavity wall or loft insulation to use the scheme.
It is hoped that removing these recommendations could reduce the costs associated with installing a heat pump on a semi-detached property by around £2,500.
