Energy suppliers are expected to increase prices yet again, according to Energyhelpline.com. Mark Todd, director of the comparison website, fears prices could rise as early as May.
"Suppliers are seeing wholesale prices continue to rise because of world events and many investors are not happy with some energy company profitability levels and want prices to go up even more, on top of the recent average rise of 5.9% over the winter," he explains.
"A major price movement of around 15% is expected between August and November but suppliers are currently thought to be considering smaller spring price adjustments before then."
Compare energy prices and switch provider
All six of the big energy providers – British Gas, Scottish Power, Scottish and Southern Energy, npower, E.ON and EDF Energy have increased their prices in recent months.
However, while energy prices might be rising, consumers don't necessarily have to put up with bigger bills. By switching to a more competitive deal it could be possible to offset any price hikes.
