Green Homes Grant

Under the UK government’s Green Homes Grant, homeowners in England can apply for vouchers worth up to two thirds of the cost of upgrading the energy efficiency of their home. The Green Homes Grant will provide vouchers to install one or more energy saving measures, including air source heat pumps (where the home has, or is having installed, wall and loft insulation).

Under the grant conditions, homeowners are able to use an MCS certified contractor to carry out renewable energy efficient measures or low-carbon heating improvement in and around their homes. It is possible to use the Green Homes Grant vouchers to install an air source heat pump as a primary improvement measure.

For your heat pump project to be eligible you must use an MCS Certified Installer who is also registered with Trustmark.
