The customer services team will be able to correct any errors on your account. If you've emailed, they'll get back to you with 24 to 48 hours.
Your annual consumption prediction might not be as refined as we'd like it to be right now. When a new customer comes over to us, we receive a file from their old supplier containing their average annual consumption figures and a history of previous meter readings. It seems like this is where the issue is stemming from. If your old supplier didn't get many readings from you, and most bills were estimated, then these figures could be out of line, hence why the annual consumption prediction we've provided seems extreme.
This doesn't mean that you will spend this much, it just mean we're not able to make a more accurate prediction at this stage. Make sure you provide a meter reading before each monthly bill, and your statement will be accurate.
Hope this helps
