EDF's first 'free electricity' Sunday is approaching

EDF Energy's Sunday Saver Challenge offers eligible customers between four and 16 hours of free electricity across four Sundays in January and February 2026, with the first date scheduled for next week; eligibility requires a working smart meter and agreement to half-hourly readings.

EDF Energy has resumed its Sunday Saver Challenge, offering eligible customers complimentary electricity on selected Sundays in January and February 2026. The programme was first introduced in 2024 and rewards customers who shift their daily electricity use away from weekday peak hours. Peak hours are reported as 4pm to 7pm. EDF says the more energy moved to off-peak times, the more free electricity can be earned for use on the designated Sundays. Key details: - Free electricity can total between four and 16 hours across four designated Sundays in January and February 2026. - The scheme rewards customers who shift daily usage away from weekday peak hours (4pm–7pm). - EDF has reported that over 210,000 customers were rewarded under the scheme after adjusting their usage habits. - Eligibility reported by coverage includes having a functioning smart meter and agreeing to half-hourly meter readings; registration opened on January 4 and closed the same day, according to reporting. - The offer is announced as households face higher energy costs, with Ofgem's energy price cap having risen by 2% between October and December and an additional 0.2% increase taking effect from January 1. Summary: The programme gives eligible customers a limited amount of free electricity on specific Sundays in January and February and is framed around shifting demand away from peak periods. It comes amid recent increases in the energy price cap. The first designated Sunday is scheduled for next week from the article's publication. Undetermined at this time.
