Gas and electricity Updated:
E.ON has become the latest gas and electricity provider to hike its prices.
Electricity prices will rise by 11.4% and gas prices by 18.1% from 13 September, with the provider blaming world events for forcing wholesale prices higher.
E.ON's dual fuel customers will suffer a rise of 15.2%.
The move is the latest in the most recent round of price rises announced by the major energy providers.
Last month, Scottish and Southern Energy announced household electricity prices will increase by an average of 11%, and for household gas by 18%, from 14 September.
Domestic tariffs at British Gas for gas are being increased by an average of 18%, and for electricity by an average of 16%, from 18 August.
Scottish Power confirmed in June that it would be increasing gas and electricity prices for retail customers by 19% and 10% respectively.
Graham Bartlett, managing director of E.ON's Energy Solutions business, said uncertainty around the world had had a huge effect on wholesale prices, with events in Japan and Libya all pushing up gas and power prices in a relatively short period of time.
"In fact, even the Bank of England's Inflation Report pointed out that wholesale gas prices had increased by around 20% between February and May alone, and that retail prices were expected to go up by double figures," he added.
Mike O'Connor, chief executive of Consumer Focus, said the news of yet another price rise will leave the average energy bill weighing in at £1,250 a year.
"Many consumers worry how they will afford to keep their homes warm this winter given other price rises and flat or falling incomes," he added.
"Four of the Big Six have now raised their prices by similar amounts.
"Customers need to know whether these increases are warranted. Customers will feel they didn't get the benefit when wholesale costs were low. Wholesale costs are around a third lower than their 2008 peak yet consumer prices have reached an all-time high.
"If consumers are to stomach such price rises, they need to know they are fair."
