A. The CEN Solar Keymark covers the certification of Solar Thermal products only and, unlike MCS, does not cover installation company certification. Consumers are able to use a Solar Thermal product approved under Solar Keymark and will still be able to claim the governments incentives (RHI and RHPP), provided the installation has been completed by an MCS certificated installation company.

Solar Keymark products are not listed on the MCS website. To search for Solar Keymark certified products, please click here to view the CEN Solar Keymark database.

A. Third party certification is an assessment carried out by an independent, third party organisation to ensure compliance with a technical specification. These organisations are known as Certification Bodies.

The Certification Bodies that carry out the MCS assessments are accredited by UKAS and licensed by the MCS Licensee to issue certification when the assessment is successfully completed.

This means that a company that holds MCS certification has demonstrated to the Certification Body that they meet the requirements outlined in the relevant MCS standards. Furthermore, MCS certified companies are required to comply with annual surveillance audits to ensure an ongoing compliance to these standards.
