Under the new voucher scheme, domestic homes not heated by mains gas will be able to apply for grants for air-to-water-source and ground and water source heat pumps.
There are minimum energy efficiency criteria, and householders must agree to complete customer questionnaires, as well as making provision for the installation of a meter to monitor their energy use and performance of their heating system.
