EDF became the first energy firm to announce a price freeze yesterday, saying it does not anticipate that its prices will rise again in 2014.
EDF Energy said its "decision to hold back the full impact of rising costs" earlier this month had been "validated by [the] confirmation that the Government will take action on energy charges".
The firm said in a statement, "EDF Energy expects to be able to maintain its lower price rise of 3.9%, as anticipated. That decision left customers with bills £80-96 lower than major competitors who had announced price increases".
EDF Energy's price increase has put the spotlight on the other big energy firms who have introduced much larger price hikes, according to the Citizens Advice Bureau.
The French-owned company are the latest member of the "big six" to raise their prices, however their increase of 3.9 per cent is significantly less than its rivals including British Gas and SSE.
“The price increase announcement from EDF today puts the spotlight on the other big energy firms who are introducing much larger price hikes. Many consumers will believe suppliers are putting profits before customers’ need to stay warm this winter," Chief Executive Gillian Guy said.
“People do not have the money to keep absorbing price rises. For many households the pot is quite literally empty. Families are facing tough choices, like cutting back on food in order to put the heating on for just a short while."
EDF Energy have been accused of being "disingenous" for claiming its 3.9 per cent price rise was a cut compared with other suppliers.
Martin Lewis, founder of MoneySavingExpert.com, said: "What really counts is not just the size of the rise, but what you were paying to begin with, and here EDF tariffs do tend to be a little more reasonable in comparison.
"Even so, there's no cause for complacency. Most of its customers, and those of other firms, are still paying far more than they need to."
Mr Lewis said households should see if they can "ditch, fix and save" to get a cheaper tariff on fixed rate deals.
EDF Energy have pledged to pass on savings to customers if the Government makes changes to the cost of social and environmental programmes.
It said the move comes in advance of a review of these schemes by the Government after Prime Minister David Cameron pledged to "roll back" green energy levies.
The statement read: "If the Government makes bigger changes to the costs of its social and environmental schemes than EDF Energy has anticipated, the company pledges to pass these savings onto customers.
"However, if changes to social and environmental programmes are less than anticipated, the company may have to review its standard variable prices again."
The size of today's increases are rather startling - 11 percent.
Rivals, on average, are 7 percent. It means that the typical EDF customer is going to be paying £122 more this year.
The company says that its charges are the lowest amongst its peers, and it's keen to explain that it's own costs have been rising.
It's having to make investments, the wholesale price of gas is increasing - we may hear more about that sort of thing next week.
Fuel price moves are a very important factor in inflation. The economy has had a boost as we heard yesterday with the GDP figures. In part, inflation has fallen from a peak last year at 5.2% down to 2.2% in september.
A large chunk of that fall was because of cheaper fuel bills, and as those fuel bills get more expensive again we could see inflation rise to 2.5% or more and that could hurt the recovery.
