YOUR Monthly Bill

Use the EON contact number to speak to someone regarding your bills and payments.

If you are concerned that your bill is too high then you can also speak to one of the customer services advisors. They will be able to help.

Reasons for a bill being higher than you expect are:

  • the bill could be estimated, in that case provide an up to date meter reading and your bill would be adjusted accordingly.
  • there may have been a balance brought forward if your bill wasn’t paid in full last time
  • your fixed rate tariff may have come to an end or there could have been a price increase
  • you could have been using more energy.
  • If you still are unsure as to why your bill may be different then call 08435 040890.

The easiest way to pay for your bill is by monthly direct debit. Contact E-on customer services on 08435 040890 to set that up. The team will recommend a monthly amount for you.

You will need to have to hand your account number and an up to date meter reading. You will also need your bank or card details. You can choose what date to make a payment on.

If you are having trouble paying then you must contact the eon customer services team as soon as possible. They will take your individual circumstances into account when trying to help. You must ensure you contact E-on as soon as you can to prevent them taking further action against you.


If you wish to make an official complaint to EON, then contact EON on 08435 040 890.

If you are not satisfied, the complaint can be escalated. All complaints are aimed to be dealt with within two days of being received. If E-on concede to any wrongdoings then they may write to apologise or provide appropriate compensation as a goodwill gesture.

If you are still unhappy with how the outcome then E-on will do an internal review of your case. This will include how it has been dealt with. They will aim to come back to you within a couple of days. If you are still unhappy then you can pass your complaint onto the energy Ombudsman.

  • closing meter readings
  • your account number
  • your details
  • your current address & your new address details.

If you wish to cancel your tariff or move it with you, EON will help accordingly. If you are moving to EON and moving to a new home, EON will help with both.
