SSE has become the first of the major energy companies to introduce price increases this year.
Tariffs will increase by an average of nine per cent from the 15th October 2012 in a move that will affect the firms’ 3.4 million gas and five million electricity customers. The price rise applies to both types of tariff.
The news has sparked fears that British Gas and other energy firms will follow. When British Gas owner, Centrica announced its latest financial results in May, it said: “The trend for retail energy costs therefore remains upwards."
E.On has already promised that it will not raise energy prices in 2012. None of the other main suppliers have made such a promise.
