Millions of UK homes are facing higher gas and electricity bills as the latest price increases from British Gas have come into effect.
British Gas owner Centrica first announced the rises in July, with gas bills up by 12.4% and electricity bills rising 9.4%.
The firm has blamed the move, its second set of price rises this year, on continuing high wholesale energy costs.
Consumer groups and analysts warned that UK prices may still have to rise.
