Step 2: We will investigate your complaint

If your complaint is about product or installation

We aim to resolve complaints as quickly as possible so if we can fix it immediately we will. If we cannot resolve it right away, then we will investigate and get back to you with a summary of actions within 10 working days of the complaint being raised. We promise to keep you informed of our progress until your complaint has been resolved and we aim to resolve any complaints within a maximum timescale of eight weeks.

If your complaint is related to the way we introduced you to Dividebuy (provider of the finance product)

We aim to resolve all complaints within 3 working days, however this may not always be possible. If we cannot resolve your complaint immediately, we promise to keep you informed of our progress until your complaint has been resolved.

Step 3: We will work to resolve your complaint

You will receive a final response email from us when we have resolved your complaint. This will explain what your complaint was about and the steps we have taken to resolve it.

If we have resolved the complaint to your satisfaction 🎉

We are pleased to have helped. It's not always easy but it's the most important thing we can do. Thank you for your patience and as ever, we are grateful for your custom.

If you are not happy with the resolutions offered

If you wish to take your complaint further, your installation support specialist can escalate your complaint to a team manager. They will review your complaint in full, and advise if there's anything else we're able to do.

Step 4: If you need to make a formal complaint

Hopefully we'll be able to solve your issue before this! However, if we're not able to reach an agreeable solution, or your complaint is open for longer than 8 weeks, we'll share the details of the relevant independent certification body.

If, before 8 weeks, it becomes apparent that we're not able to agree on a resolution for your complaint, we may reach a position of 'deadlock'. In this case, we'll write to you explaining everything from our view, and make a final offer of resolution. If you decline this offer, we'll issue a formal deadlock letter by email which you can take to the relevant certification body for independent investigation.

If your complaint is about product or installation

If you remain unhappy with the proposed resolutions, then you can refer the matter to an independent conciliation as a way of resolving the situation. We must agree to conciliation if that is your wish. The Conciliation Service used is that offered by home insulation & Energy Systems Contractors Scheme (HIES) and is described in their consumer code. It aims to reach a non-legal solution to the dispute in a reasonable timescale.
