Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government what consideration they have given to extending the £7,000 available to homeowners to support air source heat pump installation through the Boiler Upgrade Scheme to support heat networks; and what other steps they are taking to encourage heat pump installations in areas of terraced housing where ground or air source heat pump installation may prove impractical.

The Boiler Upgrade Scheme provides upfront grants to support the installation of air source heat pumps, ground source heat pumps and biomass boilers in individual properties. Ground source heat pumps attached to a shared ground loop are eligible, where the system capacity does not exceed 45kW.

We are working with industry and local authorities to develop new heat networks and improve existing ones, including through an additional £530m to extend the Heat Network Transformation Programme to 2028, and introducing heat network zoning in 2025 to identify areas where heat networks are expected to be the lowest cost solution for decarbonising heat.
