Can my supplier charge me for backdated estimated bills?

Dear Chris, I have recently received a bill for £793 from British Gas, billing me from February 2006 to May 2007. British Gas says this is due to incorrect estimated bills during this period.

Do I have to pay a debt from so long ago? The bill doesn’t even show how much money was actually paid during this period, so I don’t know whether these deductions have been made.

The additional payment they are requesting is very high and I cannot imagine how they can bill me to such an extent for such a back-dated mistake. I hope you can help/advise me!

Thanks in advance,

Thanks for contacting us about your billing dispute with British Gas (www.britishgas.co.uk). Unfortunately your supplier is within its right to charge you for backdated estimated bills if it feels you have been underpaying.

In this situation, the first thing I would suggest would be to contact your energy supplier. Call British Gas customer services on 0800 048 0202 and ask them directly the amount you’re being charged and whether this is correct.

If you feel that you have been overcharged, you need to gather together as much evidence as you can to back up your case. This includes previous bills, receipts of payment (such as bank slips or cheque stubs), and any meter readings you have. You can then file your case with British Gas’ complaints department:

Contact your supplier

The first thing you need to do is contact your energy supplier and confirm the amount that you owe them. There may have been an error with the bill, as these letters are often automated.

Phone your supplier on the customer services number below:

Energy supplier Phone number
British Gas 0800 048 0202
Scottish & Southern Energy 0845 7444 555
E.ON 0845 059 9905
npower 0845 714 5146
EDF 0800 096 2270
Scottish Power 0845 270 6543

Arrange a payment plan with your supplier

If you find that you do owe the amount in question, it is possible to arrange a payment plan with your supplier, to spread the amount you owe over a few months. British Gas says they may be able to do the following:

  • Arrange for you to pay your bill by instalments at an agreed rate
  • Agree on a more suitable payment method or tariff
  • If you’re on benefits, collect a weekly amount directly from your benefits (you should contact your Benefits Agency prior to arranging this with British Gas)
  • Provide you with advice on how to reduce your energy consumption.

For more information, read British Gas’ advice on payment methods.

Avoid estimated billing

You should always try and give your supplier an actual meter reading, rather than let them estimate your energy consumption. Energy watchdog Consumer Focus predicts that up to a third of all bills could be inaccurate due to estimated meter readings, with suppliers regularly overestimating and setting payments too high.

By taking regular meter readings, your supplier should be able to predict usage more accurately. If your bills are currently estimated, consider signing up to paperless e-billing. With e-billing you will manage your account online and put in your own regular meter readings. Paperless billing means you’ll eliminate the risk of over or underpaying on estimated bills, and help you save on your bills.


There are other ways you can cut your fuel bills too. Read our guide on saving money on your gas and electricity for more information. Hope this advice is of help Lizzie and you can arrange a payment plan with British Gas.
