What Is MCS?

The Microgeneration Certification Scheme (MCS) is a nationally recognised quality assurance scheme, supported by the Department for Business, Energy & Industrial Strategy, which is a requirement for a company who wish to commission renewable heating products, such as heat pumps.

MCS is also an eligibility requirement for the Government's financial incentives including  the Renewable Heat Incentive (RHI). This means that if you don't deal with a fully MCS accredited company to commission your heat pump then you could miss out on thousands of pounds of government incentives.
