Today (September 15, 2011) EDF Energy announced it will raise gas prices by 15.4% and electricity prices by 4.5% from November 10. The company stated that the annual cost of a standard dual-fuel bill paid for by direct debit would rise to £1,165 from £1,051. EDF is the last of the biggest six energy suppliers to announce price rises. EDF explained it had absorbed wholesale price rises for as long as possible before being forced to hike costs for customers.
