Another three million households faced higher energy bills after EDF Energy became the latest supplier to increase tariffs.
The company will raise prices for domestic gas and electricity by 10.8%, meaning its typical dual-fuel bill for a direct debit customer will rise by £122 to £1,251 a year.
EDF, which is the fifth major supplier in recent weeks to announce higher prices, said the change will take effect from December 7.
