Millions of EDF Energy customers can cut their energy bills by up to £96 a year with a simple change
Millions of households are being handed the opportunity to cut their energy bills by nearly £100 annually – with a simple change.
Power supplier EDF Energy is launching four “free electricity” Sundays this spring through its “Sunday Saver” initiative, offering customers the chance to bank up to 64 hours of complimentary power over the coming month. The offer depends on households reducing their consumption during peak weekday periods – usually between 4pm and 7pm – when pressure on the grid is at its greatest.
Participants in the April initiative can then claim their rewards on April 19 and 26, and May 3 and 10, essentially operating energy-hungry appliances without charge.
How the ‘free electricity’ offer operates
Households need a functioning smart meter transmitting half-hourly data and must register by April 5 at 11.59pm.
The programme rewards customers based on their peak-time consumption reductions:
- Reduce by 5% – gain 4 hours of free electricity
- Reduce by 20% – gain 8 hours
- Reduce by 35% – gain 12 hours
- Reduce by 50% – gain the maximum 16 hours weekly
Across four weeks, this totals a potential 64 complimentary hours. Common qualifying strategies include operating dishwashers during the night, steering clear of tumble dryers in the evenings and charging electric vehicles beyond peak periods.
EDF suggests the scheme could slash roughly £96 yearly from bills for the most dedicated participants. On average, those taking part currently secure approximately 18 hours of complimentary electricity monthly, based on company figures.
Since the programme debuted in 2024:
- Customers have clocked up over 20.5 million free hours of electricity
- This amounts to approximately £6.6 million in combined bill reductions
- The most engaged participants in 2025 secured an average of 266 hours free throughout the year
Joe Souto, Director of Retail at EDF, explained the initiative arrives as households brace themselves for shifts in energy pricing. He said: “With the energy price cap coming down in April, Sunday Saver continues to give customers a simple, practical way to cut costs and save even more when they need it most.
“If customers commit to every Sunday Saver challenge and flex their energy use, they could achieve an average of 266 hours of free electricity on Sundays, and £96 on their annual energy bills.”
Mr Souto further noted that customers can track their savings through EDF’s Energy Hub, describing it as “a straightforward way to ease pressure on bills while supporting a more sustainable electricity grid.”
You must alter your routines
While the headline promise of “free electricity” might appear attractive, it demands households proactively adjust when they consume power – and sometimes slash peak consumption by as much as 50%. This could present difficulties for families locked into evening schedules, especially during the winter months when energy requirements peak.
Nevertheless, for those capable of making adjustments, the programme represents one option to cut bills directly without changing provider or tariff.
