Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government what estimate they have made (1) of the proportion of heat pumps installed in the UK that have been manufactured in the UK, and (2) of these, the proportion that contain microchips manufactured in China.

In 2020, the Government published research that showed that 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.

However, industry data shows that there are a range of manufacturers from different countries that supply electronic circuit boards and semiconductors to the UK consumer appliance market, and the supply chain is not reliant on manufacturers from any one country.
