Scottish Power cuts prices: 7.5% gas, 3% electricity

Scottish Power has become the latest energy supplier to announce cuts in bills, starting at the end of March.

Scottish Power, which has 5.2 million UK customers, announced that gas prices would fall by 7.5% on average from 31 March. Electricity bills will also drop by 3%, following cuts by four of the other "big six" energy firms.

Npower is now the only one major supplier that is yet to announce a price cut this year. In 2008, all the major suppliers put up bills, on average by 42.5%. So far bills have only come down by a disappointing 5%. Customers can still save a lot of money by switching, however, because of the huge price variations between tariffs.
