More households complaining about energy bill errors

A growing number of households are complaining about possible errors in their energy bills.

In the first half of 2026, the Energy Ombudsman accepted 27,006 disputes relating to billing.

That’s 15% higher than it was a year earlier.

Billing disputes were also found to be the most common reason for making a complaint, as they accounted for more than (58%) of accepted cases.

What should I do if my energy bill is wrong?

If your energy bill isn’t correct, the first thing you should do is get in touch with your energy supplier.

They’ll have details on their website about how to raise a complaint.

Citizens Advice has a handy template to help you write a letter or email, so you know what information to include.

It’s possible that your supplier has made a genuine error when calculating your bill, in which case they’ll be happy to put things right.

But if the problem you’ve reported hasn’t been resolved in eight weeks or you’re not happy with their response, you can then complain to the energy ombudsman.
