Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government what estimate they have made of the number of domestic heat pumps sold in the UK last year; how many of those were produced in the UK; and how many were imported, and from which countries.

The Heat Pump Association estimates that over 98,000 heat pumps were sold in the UK in 2024. The majority of these will be for domestic use. https://www.heatpumps.org.uk/resources/statistics/

Research commissioned by the Government in 2020 found that around two thirds of heat pumps installed in the UK were imported, the majority from the European Union

The Government is supporting domestic heat pump production through the Heat Pump Investment Accelerator Competition, which provides grants to manufacturers to expand, repurpose, or build facilities, to help strengthen the UK supply chain and attract investment.
