About MCS

MCS is a mark of quality and demonstrates
compliance to industry standards that companies
strive to meet. It highlights to consumers that
companies are able to consistently install or
manufacture to the highest quality every time.

How does MCS work?

MCS is a nationally recognised quality assurance scheme which demonstrates the quality and reliability of approved products and installation companies.

For certified products, this is ensured through satisfying rigorous and established European and International standards. Installer certification includes assessing the supply, design, installation, set-to-work, and commissioning of renewable microgeneration technologies. Similar to the Gas Safe Register, MCS gives installers a mark of quality and demonstrates to customers that installations are completed to the highest quality every time.

Third Party Certification

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

The Certification Bodies that carry out MCS certification and assessment are accredited by UKAS and licensed by the MCS Licensee to issue MCS certification when the assessment is successfully completed. All MCS standards and scheme requirements are publicly available on MCS Standards section of this website.

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