EDF Energy’s Sunday Saver challenge rewards UK households for reducing electricity use weekdays to earn free power on Sundays.
EDF Energy is running its Sunday Saver challenge in February, urging UK households with smart meters to cut electricity use between 4pm and 7pm on weekdays to earn four to 16 free hours of power on Sundays.
The program, active since 2024, has already delivered over 17.5 million free hours and saved participants £5.2 million.
Over 100,000 customers received free electricity during Christmas, with the South East of England leading participation.
Customers can track usage via the Energy Hub and benefit from reduced bills while helping ease grid strain.
