How does Resolver work?

Explains your rights to you

You'll find no legal jargon in our simple, comprehensive consumer rights sections. Our guidance is tailored specifically for every type of issue.

Helps you prepare your emails

We provide a wide range of flexible email templates for you to adapt to your needs – just slot in the specific details for your case, and in a few short clicks your issue will be ready to go.

Creates a case file for you

Your case file is a secure online location for all important documents regarding your issue. You can upload photos, tickets, copies of receipts or external emails from before you raised your issue with Resolver.

Lets you record all your communications

One of the most important aspects of a complicated issue is keeping a record of all your correspondence regarding the complaint – Resolver does this for you automatically.

Lets you know when to escalate your complaint

If you’re not satisfied with the initial response from the organisation you have an issue with, our escalation process will let you know when you can raise your complaint to the next level of seniority and, ultimately to an ombudsman or regulator, where appropriate.

"Many thanks for your resolver site, I have had a possible result this morning,when an Inspector from Wellingborough Homes called and apologised for not visiting our house on the 27/07/16. He has now promised that the trees will be cut back at their cost, in November/ December, and that he will put this offer in writing,so all may work out well. Thank you for your site, as without it I doubt if we would have had such a good result (if any) by our own means. "
