EDF Energy has announced that its gas and electricity prices will rise from January 3.
The big six energy supplier has stated that the average gas and electricity tariff will increase by 3.9 per cent. Its average standard variable price offering will cost £1,300 - representing a rise of £49 a year.
Many of the energy company's 3.7 million residential customers are likely to be affected by the price hike.
SSE will increase prices by 8.2 per cent on November 15; British Gas will increase its by 9.2 per cent from November 23, ScottishPower's by 8.6 per cent from December 6, and nPower's by 10.4 per cent on December 1.
EDF has stated that the rising cost of the green levies imposed by the government won't be passed onto customers. It estimated that this would have added around £50 extra to the average yearly household energy bill if it had.
It did, however, warn that further increases in green levies could leave it having to increase its energy prices by more in the future.
The supplier said in a statement: "If changes to social and environmental programmes are less than anticipated, the company may have to review its variable prices again."
Many of the UK's energy suppliers are participating in the government's Green Deal initiative. Under this particular initiative, customers can apply to receive funding for energy efficiency measures for the home - such as new gas boilers and loft insulation. However, rather than paying this money back in a lump sum, they can pay it back through their energy bills.
