EDF has announced its Sunday Saver challenge will run throughout May, allowing customers with smart meters to earn up to 64 hours of free electricity. The scheme rewards households for shifting electricity usage away from peak weekday hours (4pm to 7pm), with free electricity granted on Sundays.
Participants can earn between four and 16 hours of free electricity each Sunday, depending on how much they reduce usage during peak times. Since the challenge began in 2024, customers have collectively earned over 22.5 million free hours, saving £7.2 million on bills. On average, participants receive 18 free hours per month.
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 of opportunities to save on bills.” He added that customers can also explore FreePhase tariffs, which offer free electricity when renewable energy is abundant.
To maximise savings, EDF suggests simple changes such as running appliances like washing machines or dishwashers outside peak hours. The offer is available to all households with a smart meter, and no sign-up fee is required.
