Home Certifications MCS MCS certified installer
MCS (the Microgeneration Certification Scheme) is the UK quality mark for small-scale renewables, certifying both installers and products. You need an MCS-certified installer for Smart Export Guarantee payments and for a Warm Homes Loan, and an installation can’t be certified afterwards. We check MCS claims on the MCS installer search. See our guide to MCS certification.
