EDF has launched a new scheme offering up to 80 hours of free electricity this summer, as households face a 13% increase in the energy price cap from July. The 'Sunday Saver' challenge rewards customers for reducing electricity use during weekday peak hours (4pm-7pm), earning between four and 16 hours of free electricity on selected Sundays in June and July.
Participants typically save around £6.62 per month in bill credits, equivalent to almost £80 a year. The top half of users save an average of £12.41 per month, or close to £149 annually. EDF says households can accumulate up to 80 hours of free electricity across five Sundays by shifting energy-intensive tasks like laundry, cooking, and EV charging outside peak times.
Joe Souto, director of retail at EDF, said: '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.'
Customers with a smart meter transmitting half-hourly data can register by May 31. Free electricity can be used on June 14, 21, and 28, and July 5 and 12. Since the programme began in 2024, over 24.1 million hours of free electricity have been distributed, representing £7.8 million in household savings.
