The Microgeneration Certification Scheme

The Microgeneration Certification Scheme

What is the Microgeneration Certification Scheme?

The Microgeneration Certification Scheme (MCS) is a UK-based scheme that certifies renewable energy products and installers. 

The aim of MCS is to give people confidence in low-carbon energy technology by defining, maintaining and improving quality.

Products and installers that have been verified use the MCS mark to demonstrate quality, competency and compliance.

If you are planning to invest in a renewable energy system you can use the scheme website to find an MCS certified installer that operates in your area and to find MCS certified products.

What is the Microgeneration Certification Scheme mark?

The Microgeneration Certification Scheme mark is designed to provide reassurance that an installer or product is certified. The image on the left shows the new (as of 2022) certification mark, however, while the rollout of the new brand takes place, you might still see the old certification mark (the image on the right).

Which technologies does the Microgeneration Certification Scheme cover?

MCS covers a range of renewable energy technologies that generate heat and/or electricity from sources that are constantly replenished, such as the sun, wind or water.

The MCS covers the following renewable energy technologies – also known as low carbon technologies:

  • Solar Photovoltaics (PV)
  • Battery Storage
  • Wind Turbines
  • Biomass
  • Solar Heating
  • Solar Assisted Heat Pumps
  • Ground/Water Source Heat Pumps
  • Air Source Heat Pumps
  • Micro CHP
  • Exhaust Air Heat Pumps

How do I get a solar MCS certificate?

When your installer finishes your renewable energy installation they should issue your MCS certificate within 10-working days of the work being completed. You can check whether an MCS certificate exists by calling the MCS Helpdesk on 0333 103 8130.

Is an MCS certificate the same as building regulations?

No. MCS installations fall under the scope of Building Regulations and as part of completion arrangements evidence must be provided of a work completion certificate issued by a local authority or self-certification of the installation works by a member of a competent person’s scheme – this is a separate process from MCS.

How do I get Microgeneration Certification?

There are four main steps to becoming an MCS certified Installer. To become MCS certified an installer must demonstrate:

  1. A commitment to quality workmanship
  2. A commitment to customer care
  3. Competency
  4. A commitment to continual improvement via an effective management system

Installation companies are assessed by a Certification Body to ensure that they meet the MCS standards. The Certification Body assesses companies to determine their company practices and performs an inspection of an installation. Certification Bodies have different prices for becoming certified, and timescales can also differ for the assessment. MCS recommends that you contact a few to decide which is best for your business.
