PARLIAMENTARY WRITTEN QUESTION
Heat Pumps: Housing (2 May 2023)

To ask the Secretary of State for Energy Security and Net Zero, what estimate his Department has made of the number and proportion of homes that are not suited to heat pump installation; and what steps his Department is taking to (a) support and (b) provide heating alternatives to those homes to improve their energy efficiency.

Asked by:
Helen Morgan (Liberal Democrat)

An estimated 90 per cent of British homes have sufficient energy efficiency and electrical connections to be heated with a low temperature heat pump (operating with a flow temperature at 45°C). Other considerations, such as having sufficient space for the outdoor unit and compliance with planning requirements, must also be considered. For buildings that are not suitable for a low temperature heat pump, alternative low carbon heating technologies, including biomass and high temperature heat pumps (with flow temperatures above 45°C), are available. Government policy supports the installation of these technologies where appropriate.
