Microgeneration Certification Scheme (MCS)

MCS refers to the Microgeneration Certification Scheme. It is a requirement of the Domestic RHI scheme that all heating systems are certified by MCS. MCS is an internationally recognised quality assurance scheme supported by the Department for Business, Energy & Industrial Strategy (BEIS), formerly known as the Department of Energy and Climate Change (DECC). MCS certifies both products and installation companies to help ensure that Microgeneration products are installed to a high standard. Working with industry we define, maintain and improve quality – certifying products and installers so people can have confidence in the low-carbon technology they invest in. From solar and wind, to heat pumps, biomass and battery storage, we want to inspire a new generation of home-grown energy, fit for the needs of every UK home and community.
