EDF's Sunday Saver free electricity offer returns in May
- EDF is the only supplier offering customers free electricity on four Sundays over the next month
- Sunday Saver has helped over 150,000 customers earn cash on their bills, worth £1.6m
EDF is continuing to offer customers free electricity on Sundays in return for them reducing their weekday peak consumption throughout May with its ‘Sunday Saver’ challenge.
Customers will be set a target to shift their electricity use away from weekday peak hours each week (4pm – 7pm) in May, to earn between four and 16 hours of free electricity the following Sunday.
EDF is the only energy provider offering four Sundays of free electricity over the next month, so customers can save cash on their bills and make the most of their weekends.
More than 150,000 customers have benefitted from Sunday Saver since the challenge began last year, earning over six million free hours of electricity, with £1.6million being credited onto Brits’ bills[i] so far.
Rich Hughes, Director of Retail at EDF, commented: “EDF's Sunday Saver challenge has been a tremendous success so far - not only is it helping customers save money but customers are also taking steps to contribute to a more sustainable electricity grid.
“Thanks to smart meters, customers can access innovative schemes like Sunday Saver and easily track their energy usage in our Energy Hub platform, helping them identify areas they can save in their house and reduce their carbon footprint.”
Customers have shared their positive experiences with the Sunday Saver challenge:
- "It makes us smile, especially when we get the text saying you have got free electricity this Sunday. Anything free is hard to come by these days."
- "I love EDF’s Sunday Saver challenge and the ability to monitor my usage and cost in Energy Hub."
- "Having a set day, time and goal has really allowed me to get some jobs done, I would otherwise have put off, but with a free electricity day it really triggers my healthy boundaries!"
Customers can sign-up for the May challenge now until Sunday 4th May at 11:59pm, with the challenge starting on Monday 5th May. Participants can use their earned free electricity on Sunday 18th and 25th May, and 1st and 8th June, and can learn more about the Sunday Saver challenge or sign up via MyAccount.
To take part, customers will need a working smart meter for their electricity supply that is sending EDF readings every 30 minutes[ii].
Progress can be tracked on Energy Hub via MyAccount, where users can access a personalised view of their household’s energy use. EDF has found that customers using Energy Hub to understand how energy is being used around their home can actively reduce their bills by up to £41[iii] a year, while also helping to cut their carbon footprint.
