Speaking to our Complaints Team

If you feel the issue hasn’t been resolved properly, just call us and you’ll be passed to our dedicated Complaints Team. If you can’t speak over the phone, they’ll email or write to you within 5 working days.
They’ll explain what’s going on, work with you to resolve the issue, and look at our internal processes to make sure it doesn’t happen again.

Independent advice

You can contact Citizens Advice at any point during the complaints procedure via their online webform or by calling the Citizens Advice consumer helpline on 03454 04 05 06. They provide free, confidential and impartial advice on consumer issues.

We aim to resolve all complaints within 5 days

But if it takes more than 8 weeks, or we can’t agree a solution, we’ll remind you that you have the right to ask the Ombudsman Services to investigate the issue.

The Ombudsman Services: Energy are an independent organisation that sorts out disputes (called Deadlocks) between customers and their energy suppliers. Their service is completely free and we have to do whatever they recommend, so long as you agree with their decision.

This could mean giving you an apology, explaining what went wrong, fixing the problem or giving you compensation. You can speak to them on 0330 440 1624 or at

Sales and marketing

All our sales and marketing activities are carried out honestly and professionally. We’re also careful to make sure all companies or people acting on our behalf are meeting the standards we pride ourselves on. Any complaints about this will be fully investigated.
