The Microgeneration Certification Scheme Service Company (MCSSCo) trades as MCS. It is a wholly owned subsidiary of The MCS Foundation. MCSSCo is incorporated under the Laws of England and Wales with registration number 07759366 and is based at First Floor, Violet 3, Sci-Tech, Daresbury, Keckwick Lane, Daresbury, Cheshire, WA4 4AB.

Since 2008, MCS has become the recognised Standard for UK products and their installation in the small-scale renewables sector. The Standards are owned by The MCS Foundation and produced by MCS, following development by independent Technical Working Groups.

This governance model is designed to raise and maintain standards and consumer protection. We are independent of, but supported by Government. MCS is responsible for the day to day running of the Scheme which has been independent of Government since novation in April 2018.

For any further information on the Governance of MCS, or to express an interest in joining a Group or Forum, please email the Secretariat,


Developing and maintaining Standards

There are several Technical Working Groups which develop MCS Standards and Scheme documents. Many members sit on European committees to develop European Standards. This helps to ensure MCS is up to date and aligns the Scheme with current EN Standards.


This change process relates to updates to MCS Scheme documents and Standards. As well as this, a formal change process for making any changes to the Scheme governance itself is also documented.


Many manufacturers sell their products internationally. MCS chooses to recognise other non-UK product certification schemes based on their product testing regimes. By recognising other product schemes which are at least as rigorous as MCS, we enable cross-border trade and reduce duplication of testing and certification.

This gives UK consumers more choice and reduces cost. Installations can only be compliant if installed by an MCS certified installer ensuring that consumers are still protected.

MCS currently recognises three European product certification schemes. These are:

  • CEN Solar Keymark for the certification of Solar Thermal products
  • CEN Heat Pump Keymark for Heat Pump products
  • Eurovent Certita for Heat Pump products

MCS product equivalence applies to the recognition of products only and does not extend to full MCS scheme equivalence. This is due to the additional requirements MCS places on installers who must utilise MCS or equivalent certified products. MCS equivalent products can be used, and if available, the prevailing government incentives can be claimed, provided the installation has been completed by an MCS certified installer.

Products recognised as MCS equivalent are listed in our Product Directory.

If you are a product manufacturer who already has a product certified by an equivalent scheme but it does not appear in the MCS Product Directory, then please contact the relevant equivalent scheme directly to request its addition.
