Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, if he will make an estimate of (a) the proportion of heat pumps installed in the UK that have been manufactured in the UK in each of (i) 2020, (ii) 2021 and (iii) 2022 and (b) in each case, the proportion that contain microchips manufactured in China.

In 2020, the Government published research that showed around 30 per cent of the heat pumps installed domestically were manufactured in the UK. This research did not consider the proportion of those heat pumps that contain microchips manufactured in China.

Industry data shows that manufacturers from several different countries supply electronic circuit boards and semiconductors to the UK consumer appliance market. The supply chain is not reliant on manufacturers from any one country.

The Government does not hold the above information for 2021 and 2022.
