MCS is the UK’s quality mark for small-scale renewable energy technologies like solar panels, heat pumps, and battery storage.

MCS Certified refers to accreditation under the Microgeneration Certification Scheme (MCS) in the UK. It certifies products and installers of low-carbon energy technologies—like solar panels, heat pumps, and biomass systems—ensuring they meet quality, safety, and performance standards. MCS certification gives consumers confidence that installations are reliable, compliant with regulations, and eligible for government incentives.
