It's important that you pay the right amount for your energy. We do our best to always use accurate meter readings when we calculate your bill. But sometimes we might need to estimate how much you've used.
If we've had to use an estimated reading, we'll tell you on your bill. We'll work it out based on the time of year, how much energy you've used in the past and how much customers with similar usage have used.
Correcting an estimated bill
If you've had an estimated bill, don't worry! All you need to do is give us an up-to-date meter reading. The easiest way is through your online account. We'll be able to give you a new balance straight away, so you won't have to wait for your new bill. You can also give us your meter reading using our online form or by calling us any time on 0345 026 7033.
We'll produce a new bill based on the accurate reading you've given us. If you're registered for paperless billing, we'll email you to let you know when it's ready. Otherwise we'll send your new bill in the post.
