Thousands of EDF Energy customers across the UK have the opportunity to slash their electricity bills by earning 'free electricity' on selected Sundays in January and February 2026. The supplier is continuing its popular 'Sunday Saver Challenge', an initiative designed to reward households for using power outside of busy evening periods.
How the Sunday Saver Challenge Works
The scheme incentivises eligible customers to move their daily electricity consumption away from the peak hours of 4 pm to 7 pm on weekdays. The more energy a household shifts to off-peak times, the more free electricity they accumulate to use on a designated Sunday. EDF states that participants could earn between four and 16 hours of free power.
Rich Hughes, Director of Retail at EDF, commented: "January is a time when many people look for new ways to save after the festive period, so we're delighted to resume our Sunday Saver challenge. Over 210,000 customers have been rewarded with free electricity as a result of adjusting their daily usage habits, reducing their carbon footprint and taking steps to contribute to a more sustainable electricity grid."
Key Dates and How to Take Part
The free electricity earned can be used on four specific Sundays. EDF has confirmed the dates as:
- January 18, 2026
- January 25, 2026
- February 1, 2026
- February 8, 2026
To participate, customers must have a working electricity smart meter and agree to half-hourly readings. Registration for the latest challenge opened and closed on January 4, 2026, ahead of the start date of Monday, January 5. Participants can track their progress via the Energy Hub within their 'MyAccount' on the EDF website.
A Timely Saving Amid Rising Energy Costs
EDF's scheme launches against a backdrop of increasing energy bills. The Ofgem price cap rose by 2% between October and December, with a further 0.2% increase from January 1. This adjustment means a typical dual-fuel household paying by Direct Debit now faces an annual cost of around £1,758.
EDF suggests that earning free electricity can be straightforward. Simple behavioural changes can make a significant difference, such as charging devices overnight, running dishwashers in the morning, or batch cooking at weekends. "We know changing habits can be tricky," the company notes, "but we hope you're up for the challenge!"
