The company has blamed the record cost of wholesale energy as the primary factor behind its increases, which will see those on dual fuel tariffs paying around £4 more for their power.
Eva Eisenschimmel, chief operating officer of EDF Energy's customer branch, said the company has done "everything possible" to keep its costs in check.
She added: "We have been absorbing some of these costs in recent months, but we now have to pass on some of the resulting rise in wholesale costs to our customers."
EDF Energy was recently commended by Business in the Community's chairman Stuart Rose for its efforts to improve its sustainability.
The company also claimed five prizes at the organisation's recent awards event.
