TrustMark registration

Apply for TrustMark registration


As a RECC member, you have satisfied our strict criteria for membership. You now have the opportunity to become TrustMark-registered through RECC.

What is TrustMark?
TrustMark is an independent, Government-backed standards scheme developed across the home improvement industry. Homeowners who contract with a TrustMark-registered business can be reassured that the business complies not only with RECC’s rigorous standards, but also with TrustMark’ scheme requirements, including the TrustMark Code of Conduct and Customer Charter. This will provide reassurance, confidence and peace of mind to consumers.

As a TrustMark-registered business you will be listed on TrustMark’s Find Your Local Tradesmen website. Many homeowners search the website for businesses able to install renewable energy systems, and they could be looking for you!

How does TrustMark work?
TrustMark works through a network of licensed ‘operators’, or scheme providers, within industry sectors. RECC is a ‘licensed operator’ for all the small-scale renewable energy technologies listed below and for battery storage. So, if you work with one or more of these technologies, you can register with TrustMark through RECC.

Solar Thermal

Biomass Boilers

Air Source Heat Pumps

Ground Source Heat Pumps

Battery Storage

Solar PV


Micro Hydro

Heating and Hot Water Controls


To register with TrustMark through RECC you must:

  • already be MCS-certified for the relevant technologies and a RECC member

The reason we don’t accept applications from businesses that are not working with MCS and RECC is that our requirements dovetail closely. This means that RECC works closely with MCS and TrustMark on compliance checking, auditing, enforcement and dispute resolution.

What is the cost of TrustMark registration?
TrustMark registration through RECC costs just £100 + VAT per year, in addition to your RECC membership fee.

How do I apply?
Applying is simple. You just need to complete the TrustMark Application Form available here and return it by email to .

Once we have completed the application process, we will accept you onto the scheme and issue you with a TrustMark sub-licence, a TrustMark certificate and a TrustMark welcome pack.
