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.

Please note that biomass sustainability RHI regulations came into force on February 5, 2015, with the obligation on RHI participants to meet the sustainability requirements from 5 October 2015. This is to help provide sufficient lead time for participants to fully understand the requirement and how to demonstrate compliance, and for suppliers on the Biomass Suppliers List (BSL) to ensure they have the necessary supply chain evidence in place to demonstrate they meet the land use criteria. Information sheets are available in the Biomass Sustainability section on the DECC policy webpage. Further information on the BSL is available for suppliers or traders of biomass fuel as well as consumers.

In addition to these biomass sustainability requirements, participants on the non-domestic RHI will still need to ensure that the fuel used is in line with their RHI emission certificate for their installation, including ensuring that the moisture content does not exceed the maximum moisture content specified.
