This announcement means that all six energy suppliers have now raised prices for the second time this year.
EDF Energy said that it had absorbed the rising cost of wholesale energy for as long as possible but now 'reluctantly' had to pass this cost on to the customer. It is estimated that this increase will effect 3.2 million customers.
Last winter EDF Energy announced a freeze on prices, only to put them up in March this year.
Energy suppliers are being investigated by the regulator Ofgem after accusations that market is operating in an anti-competitive manner.
Critics say that all suppliers move prices en masse leaving customers little choice to switch suppliers to avoid increases.
Earlier this month EDF Energy was crowned the worst energy supplier for complaints after the watchdog Consumer Focus highlighted a 19% rise in the number of complaints over the last three months.
In August EDF Energy admitted overcharging 100,000 customers over £200,000 during a seven year fault on the company's automated telephone meter reading system.
