EDF Energy is raising gas and electricity prices for its UK customers on the standard variable tariff for the second time this year.
The French-owned energy supplier said on its website that the further price hike of around 6% from August 31, will increase the combined average annual dual fuel bill by £70 per customer.
The group, part of French utility EDF, had already announced in April that it would increase dual fuel prices on the same tariff by 1.4% starting from June 7.
The first hike raised the standard variable dual fuel direct debit tariff £16 a year to £1,158 in total.
Once again the firm said the new hike reflects the continued pressures it faces from significant wholesale energy price rises.
EDF Energy pointed out that regulator Ofgem acknowledged that costs faced by all energy suppliers had increased when it adjusted the level of the prepayment and safeguard caps in April.
The group pointed out again that 60% of its customers won’t be impacted by the changes.
