EDF customers continue to save with Sunday Saver in June
- Households flexing their energy earn on average 20 hours of free electricity per month, and could receive an average of nearly £80 in bill credits annually
- Up to 80 hours of free electricity available across five Sundays in June and July
- Sunday Saver offers easy ways for customers to flex their energy use and save despite price cap increase in July
EDF’s popular Sunday Saver challenge is back for June, allowing customers to find more ways to save this summer. By flexing their energy usage outside of peak hours, households can potentially earn up to 80 hours of free electricity.
As households prepare for July’s energy price cap, with EDF’s latest price cap forecast predicting a rise to around £1,847, flexing energy use out of peak times offers an easy way to beat increasing costs.
Sunday Saver helps customers take control of their energy bills, by rewarding them for flexing their electricity use away from peak weekday hours (4pm – 7pm). Customers can earn free electricity by making small changes, helping to offset overall costs at a time when every saving counts.
The more electricity customers shift, the more free electricity can be earned the following Sunday, with between four and 16 hours of free electricity on offer.
Sunday Saver customers earn big savings on annual bill
On average, ‘Sunday Savers’ earn 20 hours of free electricity per month and have received an average monthly saving of £6.62 in bill credits by reducing their peak usage. This means customers could save up to £80 on their annual bill. Meanwhile, the most dedicated in the top 50% of participants have saved an average of £12.41 a month, a potential £148.92 off their annual bill.
Since the start of the Sunday Saver challenge in 2024, participants have earned over 24.1 million hours of free electricity, equating to £7.8 million in bill savings.1
Joe Souto, Director of Retail at EDF, said: “With the energy price cap expected to rise from July, we know many customers will be looking for simple ways to manage their bills. Sunday Saver offers an easy way to start, giving people a straightforward introduction to flexibility by shifting electricity use away from peak times, saving money while easing pressure on the grid.
“There are no catches; customers can flex their electricity use to earn free electricity every Sunday as a thanks from us. Even shifting as little as 5% can earn four hours of free electricity. Every small change can add up, helping households save money and ease the impact of rising costs.”
