How to complain about your energy supplier

Energy bills are going up, and if you're paying more, the least you can ask for is reliable customer service.

Citizens Advice has just published its latest data for England, Scotland, and Wales on the UK's largest energy suppliers based on three key categories - fewest complaints received, contact waiting time, and customer commitments. See here, external to compare the results.

For customers in Northern Ireland, you can compare deals and switch suppliers to potentially save money, with the Consumer Council for Northern Ireland offering a comparison tool, here, external.

If you want to send a letter or email, Citizens Advice has a few different letter templates that cater to different issues you may have with your energy supplier. See here, external to create your own.
