Energy company bosses defended controversial rises in customers’ bills, partly blaming green taxes for the recent hikes of over 9 per cent.
One executive also denied that prices had been put up ahead of any freeze promised by an incoming Labour government.
MPs on the Energy and Climate Change Committee fiercely questioned the companies about their pricing policies and the impact of soaring bills on millions of consumers.
Guy Johnson, external affairs director of Npower, which has announced average rises of 10.4 per cent, said the largest driver of price rises had been the cost of the so-called climate obligation on power firms.
