Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what routes are available to owners of existing solar photovoltaic systems without MCS certification to obtain independent inspections, maintenance services, accreditation or recognition by suitably qualified and competent installers.

MCS certification is not a prerequisite for consumers to access inspection and maintenance services.

Where chosen, MCS certification provides assurance across the full design, installation and commissioning process. A post-installation inspection alone cannot demonstrate that all applicable requirements were met throughout that process, and MCS therefore does not permit retrospective certification.
