Energy giant EDF will offer customers more free electricity in May, as it launches a new Sunday Saver challenge to help households cut costs. Eligible customers will have the opportunity to earn up to 64 hours of free electricity between May 4, when the challenge begins, and Sunday 7, when it ends.
The Sunday Saver challenge helps households cut their energy bills by earning free electricity on Sundays by shifting their usage away from the week’s peak hours, 4pm to 7pm. The more electricity customers shift, the more free electricity they can earn the following Sunday, with between four and 16 hours available. Joe Souto, director of retail at EDF, said: “Regardless of the weather, with Sunday Saver customers can earn free electricity every Sunday, and as we head into the warmer months, there’s still plenty

“Sunday Saver makes it simple for customers to flex their electricity use during busy weekday evenings, save money on their bills, and be rewarded with free electricity. This means customers can focus on enjoying their summer plans and not worry about their bills.”
Who is eligible for EDF’s Sunday Saver challenge?
To take part, customers will need a working smart meter for their electricity supply that is sending EDF readings every 30 minutes.
Progress can be tracked on Energy Hub via MyAccount, where users can access a personalised view of their household’s energy use.
How to sign up for EDF’s Sunday Saver challenge
Customers can sign up for May’s Sunday Saver from now until Sunday, May 3, at 11.59pm, with the challenge set to start on Monday, May 4. Sunday Saver participants can use their earned free electricity on Sunday, 17, 24, and May 31, and Sunday, June 7.
Customers can learn more about the Sunday Saver challenge on the EDF website and sign up via MyAccount.
Since launching the challenges in 2024, EDF said Sunday Saver participants have earned over 22.5 million hours of free electricity, equating to £7.2 million in bill savings. On average, customers earn 18 hours of free electricity per month.
How much free electricity can EDF customers earn with Sunday Saver?
According to EDF, customers can earn up to 16 hours of free electricity each week.
A 5% reduction in peak consumption earns four hours of free electricity; a 20% reduction earns eight hours; a 35% reduction earns 12 hours; and, for the super savers, using 50% less earns 16 hours of free electricity on a Sunday.

EDF customers can also benefit from free electricity through its FreePhase tariffs.
Mr Souto said: “If more free electricity is what you’re after, customers can also explore our FreePhase
EDF’s FreePhase Dynamic gives customers free electricity when there’s an excess of renewable generation and electricity demand is low.
The tariff has three pricing rates that reflect daily wholesale energy prices. The three-time bands: green (super off peak, 11pm-6am), amber (off peak 6am-4pm and 7pm-11pm), red (peak 4-7pm), allow customers to adapt their electricity use to make the most of cheaper rates.
