MCS Certification Explained
MCS (Microgeneration Certification Scheme) is the quality assurance scheme for small-scale renewable energy technologies in the UK. It certifies both products (solar panels, inverters) and installers, ensuring they meet defined standards for performance and safety. MCS certification is required for installers to access government incentives such as the Smart Export Guarantee (SEG) and is recognised as the primary mark of quality for solar installations.
