Well not quite free but it is DIY. As the banks are paying bugger all interest on any money that you have in there I have decided to let British Gas pay me some interest on my money.
Dead easy. I have just received my electricity bill. Now the electricity price will be going up by 7% from the 10th December. So have just sent BG a customers own read that includes all the electricity I will use up to the end of Feburary and I will receive a revised bill that will be paid.
When the Feburary bill comes (they are always estimates) I will then send them a new customers own read and I will have only used a few units of electricity.
7% profit on my money for lying.
