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.
On this page you'll find information on:
Sometimes we get things wrong; please tell us because we’re really passionate about putting it right. You can contact us using one of the options below:
Our customer care team are trained to put things right for you straight away. If they can’t, they’ll connect you with our resolution team, who are dedicated to fixing the problem for you.
The resolution of your complaint might include actions to put our mistake right, an apology, an explanation, and compensation.
We aim to resolve nine 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.
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 it and the resolution offered. 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.

If you’re not satisfied with the outcome of our internal review of your case, you can refer your complaint to an appropriate Alternative Dispute Resolution scheme. The scheme is 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. We are subscribed to two different Alternative Dispute Resolution schemes. Which scheme you contact depends on what your complaint is about. Both offer a free and independent service for customers.

Alternative Dispute Resolution and Online Dispute Resolution are there to help resolve disputes between energy suppliers and their customers. It’s free to use, and Ombudsman Services: Energy are totally independent, so they don’t take sides. If you agree with their decision, we have to act on what they say. This could be apologising, explaining what’s gone wrong, correcting the problem or offering compensation.

Quarterly complaints figures
We started publishing detailed complaints data in March 2012 as we believed that it was important customers could see how their supplier dealt with problems.
From January 2013, all suppliers started publishing complaints information in an agreed format, so we have adjusted our reports. We will continue to provide this quarterly information to show our performance over the last year. You can read about what we've been doing to deal with complaints on our report data page.
