Tell us: has your UK energy supplier back-billed you by more than 12 months? | Energy bills

We’re interested in hearing from people whose energy supplier has back-billed them for energy used more than 12 months before the date of the bill.

Ofgem rules state: “You can’t be charged for gas or electricity used more than 12 months ago if you have not been correctly billed for it, or informed about it via a statement of account, before.

“This includes situations where a supplier increases your Direct Debit because it was set too low. Suppliers cannot use this to recover any shortfall for a period longer than 12 months ago.”

If this has happened to you, what have you done about it? Have you challenged your energy company and had the extra costs removed, or have they refused to remove charges? In what other ways have you been affected?

We will contact you before we publish your response.
