With consumer protection at our heart HIES continually strives to raise industry standards, and this starts with our accreditation process.

All interested installers must undergo a strict vetting procedure and need to satisfy HIES they have high standards of quality, ethics, professionalism and customer satisfaction.

How to apply for HIES Membership?

Installers considering HIES membership can register their interest by telephone, or by submitting an expression of interest form online.

All interested installers will then receive a telephone call from a member of our communications team who will provide information about the scheme, including the benefits, processes and requirements for membership. They will also be able to answer any questions or concerns. If following this conversation, the installer would like to apply for membership, an application form will be issued.


What is the accreditation process?

Once we have received an application for membership we follow a strict process which includes the installer providing us with:

  1. A copy of their consumer contract, which should detail a consumer’s cancellation rights
  2. A copy of their guarantee/workmanship warranty
  3. Copies of their employer’s liability and public liability insurance certificates
  4. Copies of either:
    1. Last 6 months bank statements
    2. Latest filed accounts

We carry out a comprehensive credit and background history check along with conducting an online search which will include review websites and any company and management social media profiles. We also contact other Consumer Codes within the renewable sector asking them to inform us of any adverse history with the applicant company (if applicable).

How long does the accreditation process take?

The minimum length of time it can take to complete the accreditation process is two weeks, with the average length of time being three weeks.

What are the main reasons for delays in the application process?

The most common reasons the application process can take longer than expected are:

  1. Receiving the requested information from another Consumer Code exceeding the allowed time period of 14 days.
  2. Lack of information/documents provided.
  3. After an application is approved, the installer taking a long time to send in the membership agreement or pay the membership fee.
  4. Awaiting other bodies granting applicant company accreditation.
  5. Applications going to the Membership Review Panel.

What happens once an application is approved for membership?

If an application is approved for membership, the installer will be issued with a membership agreement. The signed membership agreement will need to be returned and the membership fee paid prior to their membership going ‘live’.


What are the common reasons for applications being rejected?

There are several reasons an installer will have their application for membership rejected, including:

  1. Having adverse history with another Consumer Code
  2. Associated companies having adverse history
  3. History of multiple phoenixing
  4. County Court Judgements
  5. Credit score/loss in previous accounts
  6. Management having criminal records
  7. Purporting HIES membership prior to being accepted

Rejection rates for 2018 (January – June)

Of the 223 applications received from 1st January to 30th June 2018, 17% were rejected.

What options are available for an installer whose application is rejected for membership?

If an application is rejected, a letter explaining the reasons for rejection will be issued, along with details on how to appeal against the decision. Appeals go in front of our Membership Review Panel who consider the original application, the rejection reasons and whether the issues that have caused the rejection, have been satisfied.

If the application is rejected by the Membership Review Panel the installer has the option to go to the Applications Panel (at a charge of approx. £1600, payable by the installer). At this stage, HIES will write to the installer again detailing the reasons for rejection and provide evidence that will be submitted to the Applications Panel. The installer will be required to submit their appeal which can include character references, counter evidence and any other information they feel necessary. The Application Panel will meet to discuss the appeal and review the evidence received and will produce a report on their decision, which will be sent to both the installer and HIES.

Can an installer reapply for HIES membership?

In short, yes. When an installer is rejected for membership they will be provided with the reasons for the rejection. The installer can then look at remedying the reasons which could include amending their processes and procedures in line with the comments in the report. If corrective measures are taken by the installer and they then reapply for membership, HIES, or the Application Panel may reach a different decision.
