E.ON has announced it won’t increase its energy prices this winter.
The company said its standard tariff will remain unchanged until “at least April 2017”.
The average standard variable dual fuel bill paid by householders annually is £1,047.
A spokesman said: “We have been working hard behind the scenes to make sure we could make a commitment to our customers before Christmas that we would not increase our residential standard energy prices until at least after winter. We are pleased to be able to offer that reassurance to our customers.
