Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, if his Department will make an estimate of the number of trained heat pump installers there (a) were in each year between 2019 and 2021 and (b) will be in each year between 2022 and 2025.

The Microgeneration Certification Scheme (MCS) estimates that the number of heat pump installers working for MCS Certified businesses in the UK was approximately 2,700 in 2019, 3,200 in 2020, 3,500 in 2021 and 4,000 as of July 2022. The total number of trained installers is, however, likely to be greater than this, as MCS Certification is only required for installations receiving Government grant funding.

The numbers of installers are expected to continue to increase as demand grows between now and 2025; the Heat Pump Association estimates that we will need 6,800 installers in 2023, 9,400 in 2024 and 12,400 in 2025.
