MCS standards are used by organizations to demonstrate their competence in manufacturing Biomass Systems, Heat Pumps, Micro CHPs, Solar PV, Solar Thermal and other renewable heat units.
These standards are all available on the MCS website
There are also equivalent standards for installers of the systems.
Each standard contains a series of clauses against which the organization needs to demonstrate their conformance. The MCS010 standard relates to Factory Production Control, MCS011 to Acceptance Criteria for Testing with the remainder specific to individual product design requirements.
Where organisations demonstrate to a Certification Body (CB), like BSI, that they have implemented these ideas, or clauses of the applicable MCS Standard for their product, the CB may certify them to the standard.
It is a requirement of the Domestic RHI scheme that all heating systems are certified by MCS. MCS is an internationally recognised quality assurance scheme supported by the Department for Business, Energy & Industrial Strategy (BEIS), formerly known as the Department of Energy and Climate Change (DECC). MCS certifies both products and installation companies to help ensure that Microgeneration products are installed to a high standard.
Therefore, to be able to effectively market Domestic RHI products manufacturers must be certified to the applicable standards.
