What is the Microgeneration Certification Scheme?

The Microgeneration Certification Scheme is an industry-led scheme originally supported by the Department of Energy and Climate Change (now part of the Department for Business, Energy & Industrial Strategy (BEIS)).It is an internationally-recognised quality assurance scheme for renewables installers. MCS has been running since 2008, certificating both the equipment and the installers of small scale renewable energy technologies against industry standards.

Why join our Microgeneration Certification Scheme?

The UK has set an ambitious target for carbon reduction towards the middle of this century. Achieving their goals will mean a reduction in the reliance on traditional sources of energy in favour of increasing the proportion of renewable technology. Previous governments have introduced renewable energy schemes such as the Green Deal and Renewable Heat Incentive (RHI) to drive adoption amongst homeowners. Whatever the next iteration of funding programme is, where there is demand for renewable technology, there will be equal demand for competent installers.


Once you are certified you will receive the MCS Approved Logo to gain further recognition in the minds of your customer.
