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

To ask the Secretary of State for Business, Energy and Industrial Strategy, what estimate his Department has made of the number of trained heat pump installers in the UK in 2021.

There are currently over 1300 businesses in the UK certified with the Microgeneration Certification Scheme (MCS) to install heat pumps, estimated to employ approximately 4,000 installers. The total number of trained installers is likely to be greater than this, as not all trained heat pump installers are required to be MCS Certified. MCS Certification is only required for installations receiving Government grant funding. The Government has commissioned further research into the existing heating and cooling installer workforce in England, which will be completed later this year.
