Skyrocketing gas and electricity prices compelled a record breaking four million people to change energy suppliers in 2006. That figure was whopping 750,000 more than in 2005 according to the gas and electricity regulator Ofgem.

"Energy customers have given expensive suppliers the boot with over four million moving to a cheaper supplier in the first ten months of 2006," said Ofgem chief executive Alistair Buchanan. Customers who have never switched can cut their bills by around £150 by getting a better deal for their energy?. Customers can also cut their bills by an additional £35-40 by paying for their energy by direct debit.
