British Gas, OVO, EDF and Octopus customers have all been issued with a warning as they are urged to "check now".
Customers should ensure their energy bills are not too high. Citizens Advice is urging customers with energy companies to remember your energy bill should reflect the amount of gas or electricity you’ve used, BirminghamLive reports.
It comes as households across the UK continue to face difficult financial decisions as the cost of living hits hard. Many may be looking at ways to keep their energy bills down this winter.

But if households notice a stark rise with no explanation, then people should be finding out why. Some people may be using appliances without knowing they can cost a lot to run.
Prime examples of this include hot tubs or plug in heaters. However, there are other checks you can do yourself, including seeing if your company or firm has put prices up.
Meter faults are rare, but there could also be a problem with your meter if your bills suddenly go up and you haven’t changed how much gas or electricity you use, Citizens Advice warned. People are being encouraged to first look at their most recent bill and then find the meter readings on it that your supplier used.
Then, read your meter and compare it to the number on the bill and if there’s a big difference, your supplier might have billed you for someone else’s meter. Alternatively, you might have given them an inaccurate reading.
Then, contact your supplier and give them the new reading and you should ask them to send a new bill based on the new meter reading or check you’ve been billed for the right meter.
