Estimated Meter readings.
Like many people, I've been dreading the arrival of my gas bill. It came today and they have estimated my usage, as they did on my last bill 3 months ago. Nobody has been in to read it but the figure they estimated is EXACTLY what my meter is showing today to the actual digit. I was gobsmacked. Despite the cold weather the bill is about £30 more than the same bill from 12 months ago. So I guess I haven't used that much more, but still big enough, though!
