Reporting an energy supplier is straightforward, but you have to adhere to the timescales and procedures.
The first thing you will have to do is collate all the information and evidence that backs up your case before contacting your energy company. They will then have eight weeks to respond to your complaint with a decision.
If you are not happy with the decision or do not respond within the timescale, you can raise this to the Energy Ombudsman. The Energy Ombudsman is an independent, impartial body that will be able to look at the case and take action if necessary.
For further information about reporting your gas or electricity supplier, you can contact citizens advice who will give you the information you need.
