TrustMark Registration

 TrustMark Logo


TrustMark is the Government Endorsed Quality Scheme which covers work carried out in or around homes. Joining TrustMark complements the Competent Person Scheme registration and provides consumers with added peace of mind that they are engaging with a business which has been thoroughly vetted to meet required standards and which has also made a commitment to good customer service and trading practices.

Government is promoting this scheme and has made it a condition of several funding initiatives like the Energy Company Obligation (ECO) and the Green Homes Grant scheme (GHG) and it is likely to be a requirement for future funding schemes. One of the reasons that Government is endorsing the scheme is that it gives consumers a certain level of expectation of the way a registered business will carry out work in their home through the Customer Charter. Plus, in the event that a problem does arise, TrustMark offers a range of remedies to give further protection to consumers.

Why should I register for TrustMark through OFTEC?

The TrustMark scheme offers a range of benefits to registered businesses such as:

  • Portal where you can upload information about your business
  • Financial plans for your customers,
  • Free business leads from the TrustMark customer search system,
  • Access to TrustMark’s business partnerships
  • Use of the TrustMark logo (subject to a licence agreement) and other marketing material
  • Access to Government funded installation work such as the Green Homes Grants.

How do I become registered for TrustMark?

You can apply for TrustMark registration as an extension to the OFTEC Competent person scheme (CPS) for the following trades:

  • Heating engineer (liquid fuel)
  • Electrical
  • Heat pumps
  • Biomass
  • Solar thermal

We operate our TrustMark registration scheme in accordance with the Framework Operating Requirements which set out the systems we must adhere to when approving businesses for TrustMark registration.

Businesses that wish to register for TrustMark with OFTEC must follow the TrustMark code of conduct as well as OFTEC’s rules for registration R100.

Many of the requirements for TrustMark are systems that you will already have in place, but prior to acceptance onto the scheme, one of our compliance team will carry out a desktop audit of your business.

Please note:

  • OFTEC commits to meeting the Framework Operating Requirements and ensuring registered businesses maintain the required standards of technical competence, customer service and trading practices.
  • TrustMark is available throughout the UK and recognises business registration (i.e. an enterprise).
  • This scheme sits outside of OFTEC’s UKAS ISO17065 accreditation but is subject to periodic compliance audits from TrustMark.
  • TrustMark registration can only be an extension to scope of your existing competent person scheme (CPS) registration.

To find out more please email the registration team. If you do not already hold CPS registration with OFTEC please call 01473 626 298 to discuss your options before you apply for TrustMark.
