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.

Equivalent Schemes

Currently the only other scheme which is considered equivalent to MCS is the CEN Solar Keymark Scheme. 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 under the Government’s incentive scheme, Renewable Heat Incentive (RHI), provided the installation has been completed by an MCS certified installation company.

Solar Keymark products are listed on the Solar Keymark website and MCS maintains a link to that website to ensure the product list is up to date. To search for Solar Keymark certified products, please click here to view the CEN Solar Keymark database.

If you are aware of any other product certification schemes that provide a similar level of quality assurance to MCS, please submit full details using the contact us form and this will be reviewed by the relevant technical working group.
