Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, if his Department will make an assessment of the effectiveness of the use of heat pumps in (a) uninsulated and (b) improperly insulated homes.

Evidence shows that heat pumps are suitable for a diverse range of housing archetypes in the UK and the clear majority of properties.

Modern heat pumps, capable of running efficiently at similar temperatures to an existing boiler, can increasingly be used in homes previously considered unsuitable for electrification. Other low-carbon heating solutions are available for properties that are not suited to a heat pump, and the government will continue to assess and support the options for all properties to decarbonise and reduce their energy use.
