MCS Appliance Approval

The Microgeneration Certification Scheme is a government driven scheme to promote renewable technologies. It is an internationally recognised quality assurance scheme which demonstrates the quality and reliability of Approved Products by satisfying rigorous and tested standards. HETAS are authorised to carry out  MCS biomass product certification for the Microgeneration Certification Scheme by UKAS and are able to assess your products for MCS compliance under EN 17065.

The MCS scheme offers the possibility of funding from the Governments Renewable Heat Incentive. Product certification involves type testing of products and an assessment of the manufacturing processes, materials, procedures and staff training.

The Approval Process

We are pleased to accept applications for MCS approval either from a Manufacturer or from an Agent/Sole Distributor of an appliance to the UK. The approval is based on the requirements as detailed in MCS 008; Product Certification Scheme Requirements: Biomass.

To apply for MCS Product Approval a manufacturer or distributor will complete and return to HETAS application form form 4-MCS, together with the a CE Type Test Report, Factory Production Control Details, Technical Specification Details, Installation and User Instructions and Sales or Promotional Documents.

After receiving a completed and signed form 4-MCS, the approval officer will review the submitted documents and produce a report which forms the technical file for review by the HETAS Director of Approvals and Certification.

Upon successful approval the manufacturer may state in advertising and other publications that the appliance has been certified under the MCS scheme, and show the HETAS MCS Approved Product logo. The product will be searchable on the HETAS ‘Find a Product’ search.

If you are interested in MCS Biomass approval for your appliance then please email  giving your name, company name and details of the product you require approval for, and we’ll be pleased to get back to you with more information.


 As an EN17065 certification body assessed by The United Kingdom Accreditation Service (UKAS), we must demonstrate our impartiality and independence with a committee of significantly concerned members.  For more information on or contact with the Impartiality Committee click here.
