The Scheme covers electricity generating products with outputs of up to 50kW, and heat generating products with outputs of up to 45kW. 

MCS covers microgeneration products used to produce electricity and/or heat from renewable sources. It is a quality mark that shows that a product or, an installation including one or more MCS certificated product, meets requirements defined in the MCS standards.

Kiwa offers certification for all technologies currently covered by MCS standards [hydro standards have been withdrawn]:

The MCSCertified Standards Organisation has recently issued a report: Renewing Britain: The changing landscape of home-grown energy 2008 - 2021. The report shows the dramatic change in the landscape but crucially, it provides the market with insights to shape the future. MCS has captured and been monitoring the uptake of small-scale low-carbon energy technology over the last 14 years. The report analyses this data to highlight:

  • Disparity of areas adopting domestic green energy has created rural ‘forests’ and urban ‘deserts’
  • It would take over 250 years for small-scale renewables to reach every household at current rates
  • The 10 local authorities with the lowest rates are all London boroughs
  • Scotland leads the way, with one in five homes in Orkney opting for low-carbon energy
  • Three key recommendations are outlined for government to support small-scale low-carbon energy on a national level
