WHAT WE DO

MCS: giving everyone confidence in
home-grown energy

MCS is the UK’s quality mark for small-scale renewable energy technologies like solar panels, heat pumps, and battery storage. We have two main roles – setting and maintaining standards, and providing consumer protection. 

Our standards define how renewable energy technologies should be designed and installed using MCS certified products – they are a benchmark for quality developed in close consultation with industry.
