# Renewable Energy Generation Accreditation

The main UK trade bodies overseeing renewable energy generation include the Microgeneration Certification Scheme (MCS), which certifies installers of small-scale renewables like solar panels and heat pumps, and the Quality Assurance National Fenestration Rating Council (FENSA) scheme for certain installations. The Renewable Energy Association (REA) represents larger operators and promotes best practice across the sector. For grid-connected systems, the G98 and G99 approval processes (now managed by the DNO – Distribution Network Operator) ensure installations meet safety and network standards. Additionally, installers may hold accreditation from bodies such as NAPIT or BSI, which verify technical competence. The Installer Self-Certification Scheme (ISCS) also allows some installers to self-certify their work, though this carries less third-party verification than MCS certification. Understanding which scheme applies to your project type is essential, as different systems suit different scales of installation.

To verify a provider's credentials, ask for their MCS certificate number or relevant accreditation reference and cross-check it against the official certification body's register – MCS provides a searchable database on its website, as do FENSA, NAPIT and other schemes. Request documentation of their qualifications, insurance, and any warranties offered, and check whether they're registered with Trading Standards or the local authority. Online reviews and recommendations from consumer bodies like Which? can also provide insight, but always prioritise official accreditation over ratings alone. Verification matters because accredited installers have undergone technical assessment, follow strict codes of conduct, and typically offer warranty protection; an unaccredited installer may lack proper training, use substandard materials, or disappear if problems arise, leaving you with recourse only through small claims court.
