EDF's Sunday Saver returns in January
EDF will continue to offer customers the opportunity to earn free electricity throughout January to spend on Sundays through its popular ‘Sunday Saver’ challenge.
EDF is the only supplier offering four Sundays worth of free electricity over the next month so customers can lower their bills and do more of what they love on Sundays.
‘Sunday Saver’ enables eligible customers to earn free electricity on Sundays by shifting their electricity use away from weekday peak hours (4pm – 7pm). The more electricity customers shift, the more free electricity they can earn the following Sunday, with between four and 16 hours on offer.
“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” said Rich Hughes, Director of Retail at EDF. “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.”
Registration is now open and will close on Sunday 4th January 11:59pm, ahead of the challenge starting on Monday 5th January. The Sundays where customers will be able to use their earned free electricity will be 18th and 25th January, 1st and 8th February.
To be eligible, customers must have a working smart meter for their electricity supply and be opted into half-hourly meter reads[i]. Progress can be tracked on Energy Hub via MyAccount, where users can access a personalised view of their household’s energy use.
Customers can find out more about the Sunday Saver challenge here and sign up for the challenge via MyAccount.
