We've always been on estimates and they tend to estimate about £50 lower than our usage so I can't complain![]()
Nope, as I always compare my meter reading to their estimate one. Can never lose![]()
This makes no sense!

It will always come back to the ultimate 'real world' meter reading no matter what. Estimates are just that - a pure guestimate of your usage based on previous actual readings. The company will want money for all the electricity you've used.
How long have you been saving these £50 chunks? If it's been a few quarters then you might owe them a couple of hundred pounds.

Until you move and they send you a bill for £4300![]()
