EDF launches cheapest fixed tariff among large suppliers
EDF has launched the cheapest energy-only fixed deal among major suppliers[1], marking significant savings against both the current and July price cap.
EDF’s Simply Fixed Direct Jun26v10 12-month tariff, priced at £1,614 for an average dual fuel customer paying by direct debit, is £235 cheaper than the current price cap (£1,849), and £106 cheaper than the July price cap (£1,720).
The new fixed deal is expected to remain competitive over the next year according to EDF’s price cap prediction service, which forecasts the price cap will begin rising again from 1st October. Based on EDF’s current predictions, the new fixed deal will be at least £125 cheaper than Ofgem’s price cap over winter.
The tariff is available to new and existing customers. Customers can also benefit from no exit fees when signing up directly through EDF.
"At EDF we’re always looking for ways to help customers save cash and carbon which means keeping our prices as low as possible. With current wholesale costs decreasing, this deal means customers can lock-in a price now that is cheaper than both the current and upcoming price cap, which falls next month,” said Rich Hughes, Director of Retail at EDF.
Commenting on recent wholesale cost changes, he continued: “The market remains volatile. Our prediction service currently forecasts that the price cap will rise again in October, with winter prices increasing a further £37 in the past week. Predictions for January and April have also increased by a similar amount, making now a crucial time to lock in lower prices.”
The deal could be removed at any time due to volatility in global wholesale prices.
EDF frequently offers the cheapest fixed rate deals amongst major suppliers and is helping more customers save cash on their bills this month with the return of its ‘Sunday Saver’ challenge. ‘Sunday Saver’ encourages customers to shift some of their electricity use away from weekday peak hours (4pm – 7pm)[i] to earn up to 16 free hours of electricity the following Sunday, and EDF has credited £2million onto its customers’ bills[2] via the scheme so far.
For EDF customers that refer a friend, the energy supplier is also giving both customers £50 off their energy bill. T&Cs apply. For more information, click here: https://www.edfenergy.com/refer-a-friend
