Equivalence to MCS - Solar Keymark Scheme

There is another scheme which is equivalent to MCS called the CEN Solar Keymark Scheme, which is for solar thermal products. 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 RHI, provided the installation has been completed by an MCS certificated installation company.

Please note that there may also be other equivalents to MCS, but at present we are only aware of the CEN Solar Keymark Scheme. If you have an enquiry regarding equivalent schemes, please contact the Department of Energy & Climate Change.
