Microgeneration Certification Scheme (MCS)

What is the Microgeneration Certification Scheme?

The Microgeneration Certification Scheme is an industry-led scheme originally supported by the Department of Energy and Climate Change (now part of the Department for Business, Energy & Industrial Strategy (BEIS)).It is an internationally-recognised quality assurance scheme for renewables installers. MCS has been running since 2008, certificating both the equipment and the installers of small scale renewable energy technologies against industry standards.

Which renewable technology can be MCS certified?

Microgeneration products are technologies that produce heat or electricity from a renewable source (with a capacity of up to 45kW for heat; or up to 50kW for electricity. Stroma Installer Certification provides Microgeneration Certification Schemes for a number of renewable technologies. The MCS standards required for compliance will vary depending on the type of renewable installation work for which you want to be certified:


Type Measure
All MCS installers MCS 001 'Micro-generation Installer Certification Scheme for supply, design, installation, set to work, commissioning and handover'
Green Deal approved installers MCS 023 'Additional Requirements for MCS Installation Companies to become Green Deal Authorised'
Solar Thermal installers MIS 3001 'Solar heating systems'
Solar PV installers MIS 3002 'Solar photovoltaic systems'
Heat pump installers (Air source and Ground source) MIS 3005 'Heat pump systems'
Biomass installers MIS 3004 'Solid Biofuel Heating Systems'

Please refer to the MCS website for guidance on all MCS application standards.

You will need to provide evidence of appropriate, policies, procedures and insurance documents. In addition, members of our Microgeneration Certification Scheme need to be members of the Renewable Energy Consumer Code (RECC) or the Home Insulation & Energy Systems (HIES) contractor scheme.



How do we assess you for MCS?

First, we will review your documentation in the office to ensure procedural compliance. Following this we will visit you on site to see a practical installation for each renewable technology. This assessment procedure will be repeated on an annual basis to maintain standards and ensure compliance.
