Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what the estimated total cost to households is of replacing gas boilers with heat pumps.

The cost to a household of replacing a gas boiler with a heat pump will depend on take-up of the available Government support, the size of the heat pump unit required and any ancillary works such as replacing radiators.

Other support schemes are available for low-income households and social housing, and for eligible homes a heat pump installation may be supported at no cost to the household.
