In a continued effort to raise industry standards and improve levels of protection for consumers, HIES has recently become a TrustMark Scheme Operator.


HIES founder, Tony Pickup, commented: "The whole purpose of HIES is to provide the most robust level of consumer protection possible when it comes to renewable energy products. Therefore, it made sense to become a TrustMark Scheme Operator as our installers can demonstrate they are able to deliver the kind of competence and quality expected of the Government Endorsed Standards Scheme, along with the certainty that if there is a problem, HIES as an organisation has a suite of remedies to ensure satisfaction."

TrustMark CEO Simon Ayres commented on this latest development: “It is great news that HIES have been accepted as a Scheme Operator for TrustMark. As we move forward as an organisation it is increasingly important to work with businesses like HIES that can ensure customers receive the same level of protection and satisfaction when having renewable energy products installed, as they should with any other trade. As TrustMark develops we look forward to working with many other organisations to continue to drive standards and widen choice for consumers seeking to improve their homes.”

TrustMark is the only Government endorsed standards scheme for trades within the home improvement industry; and by being TrustMark registered, a company is demonstrating their commitment to work to these standards; providing trust, confidence and peace of mind to consumers.

In order to become TrustMark registered, companies must be a member of a ‘Scheme Operator’ (relevant to their business), such as HIES.

What are the benefits of being TrustMark registered?

There are many benefits to being a TrustMark registered trader. In addition to being a well-recognised and trusted scheme, their ‘Find a local tradesman’ facility receives around 750,000 search requests each month from consumers looking for reliable and recommended trades. All registered companies will be added to this search facility, helping them to secure more business. Other benefits to becoming registered include the use of the TrustMark logo, free van stickers, a web page on the TrustMark website and engagement on social media.

With HIES now an Approved Scheme Operator, our members have the option of becoming TrustMark registered.

How much does it cost to be TrustMark registered?

The cost for being TrustMark registered through HIES is just £120 + VAT per year. This is in addition to your HIES membership fee and is payable via direct debit at £10 + VAT per month.

How can HIES members become TrustMark registered?

The process for being TrustMark registered through HIES is as follows:

  1. Contact our TrustMark administrator Lauren Jones, via email at to register your interest.
  2. Lauren will respond via email attaching a copy of the TrustMark sub-licence agreement together with a set of questions to answer and a request for documents that need to be provided, which relate to the TrustMark core criteria. We will also need to check which of our approved TrustMark trades the member wishes to be listed for on the TM website.
  3. Once the signed sub-licence agreement has been received, along with the requested documents and answers to the questions to satisfy the TrustMark core criteria, we shall process the membership with TrustMark.
  4. After membership has been processed the member will then appear in the search facility on the TrustMark website. They will also be sent the downloadable TrustMark dynamic logo (relevant to their HIES approved trades) and TrustMark van stickers.
