My point is I know that I used 333 units over the total 91 days but not that my gas use almost doubled after the price rise. Seeing that at the date of the change over point for the price rise ,Scottish Power Manweb had no ideal how much gas I have really used until my meter was read on the 04/12/05. In other words I think I used more gas at the lower price and less gas at the higher price.
