Energy company Powergen has said it is putting up its gas and electricity prices for the second time this year.
The company’s domestic gas prices will go up by 18.4% and its electricity prices by 9.7% from 21 August.
It blamed the latest move on the rising wholesale cost of gas which it said had climbed 87% since the start of 2005.
The latest increases bring Powergen into line with the other major energy suppliers, who have all raised prices for a second time this year.
In March, Powergen increased its gas prices by 24.4% and its electricity prices by 18.4%.
