complaints procedure

If you are unhappy with your installation or the service you have received from either your installer or from Flexi-Orb, then you have the right to register your complaint and have your concerns addressed.

Please follow our guidance below to raise your issues.


If you have an issue(s) with your installer and/or your installation, you should first inform your installer. Do this by sending a formal letter of complaint, outlining your concerns. You should then allow your installer 10 working days to respond to your complaint. 

Your installer will need time to investigate and resolve your complaint and this will depend on the complexity of the issue. They should be able to provide you with their complaints process, which should include timeframes to acknowledge the complaint and either to resolve, close or keep you updated on its progress.

If, after allowing your installer the opportunity to resolve your issue(s) you are not happy with the outcome, you then need to notify us by completing our complaint form and attaching any supporting documentation. We will acknowledge your complaint within 5 working days and inform you of any action that has, or will, take place.

Depending upon the nature, we may need to refer your complaint to your installer’s Certification Body, Alternative Dispute Resolution (ADR) provider and/or the Energy Performance Validation Scheme (EPVS).


In order to become accredited with a Certification Body your installer will have had to undergo a rigorous assessment process and demonstrate their competence to carry out certain installations. They must also undergo annual assessments to ensure continued competence.

If your complaint is with the installer’s workmanship or relates to any safety issue, then we may refer your complaint to the appropriate certification body to investigate and assess whether the installation has been completed following the appropriate certification standards.


Alternative Dispute Resolution is an unbiased process whereby your complaint is accessed by a neutral person who then communicates with both parties in order to reach a fair conclusion. If required, the ADR provider can instruct an independent inspection of the installation to gain better insight into any issues.

In the event a conclusion cannot be agreed upon, your complaint would then be forwarded to the Ombudsman who will make a final decision on the situation without having to go through the courts. The Ombudsman’s decision is legally binding on the installer.  

Whether your complaint relates to customer service issues, system faults, incorrect product/system installed or anything else, if we are not able to resolve it quickly and informally for you, it is likely we will refer your complaint to your installer’s ADR provider. The outcome of any complaint which has been dealt with by the ADR provider will be shared with Flexi-Orb, allowing us to take action against the installer, if necessary.


EPVS is a certification standard that validates the processes used by installers, to ensure consumers are provided with accurate performance and savings estimates when purchasing renewable energy products.

If your complaint relates to the performance of your system and/or any savings you feel you are not achieving, then we can pass your contractual paperwork to EPVS to carry out their validation checks.  

I HAVE A complaint about a certification decision

If you are an installer and your complaint is about a certification decision, or any other interaction with a certification body, you should direct your complaint to them in the first instance.

If you are still unhappy with the outcome following closure of your complaint with the certification body, you may then raise your complaint with us using the procedure below.


We hope that you are never dissatisfied with our service, but we view complaints as an opportunity to learn and improve for the future – as well as a chance to put things right for the person or organisation involved. Should you need to complain, we want you to know that we will take your dissatisfaction seriously, make it easy for you to let us know about it, and keep you updated as it goes through our clear, documented process and procedure.

If you have a complaint about any aspect of our service you can contact us in one of the following ways:

We find that most issues can be resolved quickly and informally, but if not, or if you are not satisfied with the outcome, your complaint will enter our process to ensure that you are treated fairly and reasonably.

  • The complaint should be acknowledged in writing by the person handling the complaint within 5 working days, and will say who is dealing with the complaint and when you can expect a reply.
  • We aim to give you a definitive reply within four weeks. If this is not possible because, for example, an investigation has not been fully completed, a progress report will be sent with an indication of when a full reply will be given.
  • We will describe the action taken to investigate the complaint, the conclusions from the investigation, and any action taken as a result of the complaint.
  • If you feel that the problem has not been satisfactorily resolved, you can appeal the outcome and request that the complaint is reviewed at Board level. As above, you should expect to receive confirmation of the escalation of the complaint, who is dealing with it and when you can expect a reply, within two weeks, and a formal response within a maximum of four weeks.
  • You have the right to appeal the decision by referral to an Independent Arbitrator. Flexi-Orb will facilitate this process by ensuring that you are made aware of the process and we will help you make the appeal. Within the Scheme Terms and Conditions, both parties agree that any dispute that cannot be resolved can be settled under the Rules of Arbitration by one or more arbitrators appointed by joint agreement of the parties or, if agreement cannot be gained, the Arbitrator will be appointed by the Centre for Dispute Resolution.
