EDF Energy’s 'Sunday Saver Challenge' is offering eligible customers up to 16 hours of free electricity across four Sundays in January and February 2026, encouraging them to shift energy use from weekday peak times (4–7 pm) to off-peak hours.
The program, running since 2024, rewards participants who adjust habits like charging devices or running appliances outside peak periods.
Over 210,000 customers have previously benefited.
Participation requires a smart meter and consent to half-hourly readings, with registration closed as of January 4.
Savings help offset a 2.2% energy price rise since October 2025, with average annual bills at £1,758.
Customers track progress via EDF’s Energy Hub.
