EDF brings free electricity days back for March
EDF has announced its popular ‘Sunday Saver’ challenge will return in March, with improvements that will make it easier for customers to earn hours of free electricity.
With energy prices on the rise, EDF is supercharging Sundays to help more customers save cash on their bills and reduce their carbon footprint. Available to EDF customers on any tariff, ‘Sunday Saver’ challenges customers to shift some of their electricity use away from weekday peak hours (4pm – 7pm)[i] to earn free hours of electricity the following Sunday. The more electricity customers shift, the more free electricity they can earn.
Following a break in January and February, EDF has relaunched Sunday Saver with enhanced benefits so customers can now track their earned hours and see how much credit they have accumulated off their bills in Energy Hub via MyAccount.
The energy supplier has also reduced the threshold for earning four hours of free electricity, allowing more customers to benefit from the initiative.
Rich Hughes, Director of Retail at EDF said: “With energy prices rising, we know many household budgets are stretched, which is why we want to help more people still do the things they love on a Sunday for free, saving them cash on their bills and helping them to reduce their carbon footprint.”
EDF is helping customers to save money with its Simply Fixed tariffs, with its cheapest fix currently offering savings of £166 against the new price cap level. EDF’s Simply Tracker Mar26 tariff also guarantees customers savings of £50 year against the price cap, for a dual fuel customer.
Customers can find out more about the Sunday Saver challenge here and sign up for the challenge via MyAccount. Registration is now open and will close on Sunday 2nd March 11:59pm, ahead of the challenge starting on Monday 3rd March.
To take part customers must have a working smart meter for their electricity supply and be opted into half-hourly meter reads[ii].
Customers can access a personalised view of their households’ energy use on Energy Hub via MyAccount. EDF has found that customers who are using Energy Hub to understand their usage are able to actively reduce their bills by up to £41[iii] a year as well as helping to cut their carbon footprint.
