MCS scheme approved for CHMM
3rd April 2025
UK: The Microgeneration Certification Scheme (MCS) has been announced as an approved certification scheme for the UK’s Clean Heat Market Mechanism (CHMM) launched on 1 April.
The CHMM supports the development of low-carbon electric heat pumps. It places an obligation on manufacturers supplying gas and oil boilers in the UK market.
Manufacturers must meet targets for the installation of heat pumps in existing properties in proportion to their sales of fossil fuel boilers. Manufacturers can do this by supplying heat pumps themselves or by getting credits from other manufacturers.
The scheme will run until at least 2029 and applies to the whole of the UK.
All heat pump installations under the scheme must be registered on the MCS Installation Database (MID). This is to provide assurance that the installations are genuine and to mitigate the risk of them being counted multiple times. The requirement for heat pumps to be registered on the MID also means that installations are MCS certified. This provides an additional layer of assurance that they are being installed to industry-recognised standards, by certified installers who are using certified products.
“As the heat pump market continues to grow, we need to ensure that consumers are protected. This is crucial in ensuring everyone has confidence in home-grown energy. The best way to achieve this is through high-quality installations and by providing strong consumer protection in case anything does go wrong,” said MCS CEO Ian Rippin.
