Microgeneration Certification Scheme (MCS)

The future is renewable

The UK has set a target of an 80% reduction in greenhouse gas emissions by 2050. Renewable technology is key to delivering a low-carbon energy output. Our Microgeneration Certification Scheme (MCS) qualifies tradespeople to install renewable technology & access Renewable Heat Incentive (RHI)-funded customers.

10,048
Domestic RHI installations accredited*

6,061
Non-Domestic RHI installations accredited*
*Figures accurate as of Sep 2014

MCS membership - from only £100.


We group our MCS measures so your application is more straightforward. Assessments can occur in one site visit. With Stroma you save money and as a renewable installer RHI-funded customers are within reach.

RHI. The Renewable Heat Incentive.

The Government recognises that renewable technology plays a huge role in meeting carbon reduction targets. As an MCS certified renewable installer the incentive to help customers is timely. 1,000 installations were RHI-funded in the first month of the scheme. Don’t miss out!

Biomass. Now being accredited.

Early RHI figures showed biomass as a major funded technology for customer applications. Get certified with Stroma for our new biomass measure now covered by our MCS installer scheme.


Full scope MCS. All measures certified.

Our MCS scheme offers certification for all major renewable technologies. Join us and offer customers RHI-qualifying measures. Includes our brand new Biomass measure, plus Wind Turbines coming in early 2015.

Talking 'bout Micro-generation. All questions answered.

  1. What is MCS?

The Microgeneration Certification Scheme (MCS) is an internationally-recognised quality assurance scheme for renewables installers. MCS gives a mark of competency and demonstrates to customers that as a certified installer you can install to the highest quality all the time.

MCS Certification also enables your installations to qualify for Government financial incentive schemes such as the Feed-In Tariff (FIT) and Renewable Heat Incentive (RHI) – making it crucial to most renewables customers.

Customers are increasingly demanding that installers are MCS certified, to ensure that their installation qualifies for major Government financial incentives such as the Feed-In Tariffs and Renewable Heat Incentive, or for Green Deal finance.

MCS has been running since 2008, certificating both the equipment and the installers of small scale renewable energy technologies against industry standards.

The scheme is driven by the legally-binding requirement for the UK to meet 15% of energy demand from renewables by 2020. The Government’s aim is for a significant proportion of this can be met through small-scale generation by the energy users themselves, and the MCS was formed to encourage this by raising consumer confidence and forming a quality framework to support the incentive schemes.


  1. Who is involved in running the Microgeneration Certification Scheme?

The Microgeneration Certification Scheme is an industry-led scheme supported by the Department of Energy and Climate Change (DECC). Gemserv has been appointed by DECC as the MCS Licensee.

MCS certification can only be provided by a licensed and UKAS-accredited certification body. Stroma Certification is licenced to operate MCS certification schemes for installers, which are accredited under UKAS Accredited Product Certification ISO17065.


  1. What is ‘microgeneration’ and what are MCS certified products?

For the purposes of the MCS scheme, microgeneration products are technologies that produce heat or electricity from a renewable source, and which have a capacity of up to 45kW (for heat) or up to 50kW (for electricity).

MCS certification is available for microgeneration products, as well as for the installers who fit them. To qualify for Green Deal finance, RHI incentives or the FITs, your installations will need to be based on eligible MCS certified products. You can find details of qualifying products using the Microgeneration Certification Scheme Product Search.


  1. What are the key requirements for MCS certification?

Stroma Certification assesses our MCS members to confirm that they meet the following requirements:

  • Competent to undertake inspections and installations.
  • Suitably qualified (as specified within the National Occupational Standards).
  • Adequately insured, with Professional Indemnity (PI) and Public Liability (PL) cover.
  • Adopt operational procedures that provide quality assurance and ensure the consistency and accuracy of installations.
  • Keep appropriate paperwork for auditing.
  • Are fully informed of legislative developments and incentives, and undertake a minimum level of continuing professional development (CPD).
  • Maintain a high standard of operational integrity, whilst undertaking both the on-site and off-site activity associated with the notifiable works.
  • Are members of the Renewable Energy Consumer Code (RECC) - formerly the Renewable Energy Association (REA).

  1. What are the relevant MCS standards?

The standards that you will need to comply with vary depending on which types of microgeneration installation work you want to be certified for:

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 MIS 3005 ‘Heat pump systems’
Biomass MIS 3004 Solid Biofuel Heating Systems
Wind Turbines (launching Spring 2015) MIS 3005 Micro and Small Wind Turbine Systems

  1. Which MCS measures can Stroma certify?

Stroma Certification is authorised to run Microgeneration Certification Schemes (MCS) for solar photovoltaics (solar PV), solar thermal, biomass, heat pumps and wind turbines.

We can also certify you against the MCS Green Deal ‘top up’ standard, MCS 023, for all measures.

All of Stroma’s installer certification schemes are grouped into convenient groups of measures; this allows us to offer you savings by grouping assessments into one site visit. For MCS, our Groups of Measures are as follows.
