How do I check if my installer is MCS-certified?

Search the MCS Installer Register at mcscertified.com. Enter your postcode to find certified installers near you. The certificate number should appear on all quotes and documentation.

Can I get SEG without MCS?

No — SEG requires certification through MCS or an equivalent accredited scheme, and individual suppliers set their own evidence requirements. Without MCS or an accredited equivalent you would not be able to claim export payments, so you would generate electricity without being paid for the surplus.

What happens during an MCS inspection?

MCS installers are audited annually. Random installation inspections check: wiring quality, labelling, DNO notification, performance testing, and documentation. This ensures ongoing quality.

Is MCS the same as NAPIT or NICEIC?

No — NAPIT and NICEIC are electrical competence schemes. MCS is specifically for microgeneration (solar, heat pumps). MCS installers may also hold NAPIT/NICEIC certification for electrical work.

What is MCS certification for solar?

MCS (Microgeneration Certification Scheme) is the UK quality standard for solar installations. Why it matters: (1) QUALITY — MCS installers must follow strict installation standards (MIS 3002). (2) SEG ELIGIBILITY — SEG requires certification through MCS or a scheme accredited as equivalent. (3) CONSUMER PROTECTION — MCS provides a complaints and arbitration process. (4) BUILDING REGULATIONS — MCS installers self-certify compliance with Part P (electrical) and Part L (energy). (5) INSURANCE — most home insurers require MCS installation for solar cover. (6) PROPERTY VALUE — MCS certificate is needed when selling a home with solar. Without MCS or an accredited equivalent you cannot claim SEG payments, and you lose building regs self-certification, straightforward insurance cover and easy evidence when selling. MCS adds approximately £200-£500 to installation cost — a trivial amount for the protection it provides.
