Microgeneration Certification

MCS Certified

What is the Microgeneration Certification Scheme?

MCS is a regulatory body that certifies low-carbon products and installations used to produce electricity and heat from renewable sources - such as air source heat pumps.

To benefit from financial incentives from the UK Government such as the Renewable Heat Incentive any small-scale renewable technology, installation and maintenance must be done correctly and certified by MCS.

Why MCS is critical to get an energy saving grant?

For a homeowner to be eligible for the Renewable Heat Incentive an air source heat pump installation must:

  • Be installed by an MCS certified installer
  • Use MCS & Trustmark certified products

MSS work with MCS certified installers and also offer installation training courses. Interested? Get in touch.

Risks of non-MCS certified Air Pump installations

If you are interested in generating your own energy, it is important to use an MCS certified installer so that the technology you choose is specified, installed and maintained correctly.

Not all installers are MCS certified and therefore your heat pump installation may not comply with MCS quality standards. Please be aware there are risks to be aware of if the installation is MCS non-compliant. For example:

  • Homeowners would not be eligible for government grants
  • Installation standards may be poor
  • Potential for inefficiency
  • Higher energy bills

Ensuring your Air Pump is MCS Compliant

MCS issues licenses to approved companies to test and license installations - MSS is an approved MCS licensee and can issue MCS certification through the MCS system.

Our survey, design and installation process is designed to ensure the highest standards are maintained.

After the commissioning date - when it has been tested and officially approved with a Microgeneration Certification Scheme certificate - you can then apply for a grant.
