What is a MCS certificate?
A Microgeneration Certification Scheme (MCS) is a quality assurance scheme that is nationally recognised and supported by the Department for Business, Energy and Industrial Strategy (BEIS).
A MCS forms part of the eligibility requirement for financial incentives, such as the Feed-in Tariff and the Renewable Heat Incentive.
If you want to register your solar panels for the Feed-in Tariff you will need your MCS certificate.
