UK household’s energy bills could rise by as much as £414 next month as a range of fixed deals come to an end.
That’s according to price comparison service uSwitch.com, which says seven suppliers have 16 fixed deals expiring on the 30th of April, after which their customers will be rolled onto expensive standard variable tariffs.
Customers facing the biggest hikes are those with npower (£414), First Utility (£397) and ScottishPower (£373).
The worst of these is a price jump of 54%.
Six of the seven suppliers ending deals this month have already announced price rises this year.
Ofgem’s rules allow customers to switch suppliers without paying exit fees from 42 days before their plan end date, so consumers are free to shop around without penalty.
Some energy consumers could slash their fuel bills by a quarter if they switched supplier.
