We try very hard to get it right but we know we get it wrong from time to time. We want to learn from our mistakes though, which is why we want to know if you’re not happy.

What counts as a complaint?

A complaint is any contact from, or on behalf of, a customer or potential customer who is not satisfied with any part of our service. We will not respond to mass lobbying campaigns as it affects the overall service our customers expect from us.

We aim to resolve eight out of ten complaints within two days. We expect to be able to resolve most other complaints within three weeks, but we’ll tell you if we can’t.

Reviewing your complaint

If you’re not satisfied that we’ve sorted it out, or you’re not happy with how we’ve dealt with things, we’ll carry out an internal review of your case.

We’ll look into how we’ve handled your complaint, what advice we’ve given you and what we’ve offered to do to see if we should do anything differently. We will let you know what the outcome of the review is and the reasons for our decision.

We will normally take less than two working days to carry out the review. If we agree to carry out other actions following the review we will let you know how long it is likely to take.

2015 saw our first independent over the phone research for our small to medium business customers as part of our ongoing commitment to be fair and honest in our dealings with you. We asked a selection of customers who had recently raised a complaint with us how satisfied they were with us about:

    • the overall handling of their complaint
    • outcome of their complaint
    • and how fairly they were treated
