Business customer complaints

We're always working to make things better for you, 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. 

Resolving your complaint

Our customer care team are passionate about putting things right for you. If they can’t, they’ll connect you with our Resolution team, who are dedicated to fixing your problem.

We aim to resolve eight out of ten complaints within two days and most other complaints within three weeks. We’ll tell you if we can’t. The resolution of your complaint might include actions to put our mistake right, an apology, an explanation or compensation.

We don't respond to mass lobbying campaigns as it affects the overall service our customers expect from us.

Reviewing your complaint

If you’re not happy with how we’ve dealt with your complaint, we’ll carry out an internal review of your case.

We’ll look into how we’ve handled your complaint and let you know the outcome of the review and the reasons for our decision.

The review normally takes less than two working days. If we agree to any further action we'll let you know how long it's likely to take.

Alternative Dispute Resolution

If you’re not satisfied with the outcome of our internal review of your case, you can refer your complaint to one of the two Alternative Dispute Resolution scheme's we subscribe to. The schemes are designed to provide an independent review of complaints and decide the outcome where a supplier and their customer are unable to agree on a resolution. This is a free and independent service.
