What is back billing?

A backbill is a ‘catch-up’ bill sent to you by your gas or electricity supplier when you haven’t been correctly charged for your energy use. Backbills can be for any amount, but we have put in place rules which define when your supplier can charge you, and to prevent backbilling beyond 12 months. 

What are the rules for back billing?

Your supplier can’t ask to be paid for unbilled energy used more than 12 months ago, if you haven’t been accurately charged for this usage before. Suppliers must make these protections clear in their terms and conditions.
