Question to the Department for Energy Security & Net Zero:
To ask His Majesty's Government what estimate they have made of the number of approved contractors in the Microgeneration Certification Scheme that can work on the Boiler Upgrade Scheme in listed properties.
The Microgeneration Certification Scheme (MCS) is a nationally recognised quality assurance scheme for renewable technologies, setting high standards for products and installations, including under the Boiler Upgrade Scheme (BUS).
As of April 2025, there are 1,580 MCS registered companies with an active BUS account, with these companies ranging from sole traders to larger corporations with large number of installers.
The Government’s Heat Training Grant continues to support existing heating engineers in England to take the relevant training to install heat pumps. Since its launch in July 2023, over 6,500 individuals have gone through heat pump installation training funded through the scheme.
