Here's where you can see our full Terms and Conditions of the trial

Terms & Conditions for EDF’s “Beat the Peak+” Trial 

These Terms and Conditions apply to the Beat the Peak+ trial (the “Trial”). By participating in the Trial, the Customer agrees to be bound by the following Terms and Conditions: 

The Trial  

  1. The Trial will be facilitated by EDF Energy Customers Limited, a company incorporated in England and Wales with company number 02228297, whose registered address is at 90 Whitfield Street, London, W1T 4EZ (“EDF”). 
  2. The Trial period will start at 00:01 on Monday, 1 April 2024, and end at 23:59 on 30 March 2025 (the “Trial Period”). EDF may choose to end the Trial at any time before 30 March 2025 or to extend it beyond 30 March 2025 and will notify the Customer if they do so. 
  3. To take part, the Customer must register interest in the Trial. By participating in this Trial, the Customer agrees to be bound by these Terms and Conditions (“the Customer”).
  4. These Terms and Conditions are separate from the terms and conditions for the supply of electricity that the Customer has with EDF and will not affect the existing rights and obligations under those terms. 


5. To be eligible for the Trial (“Eligible”), the Customer must, for the duration of the Trial: 

  • at all times comply with these Terms & Conditions 
  • be aged 18 or over
  • reside in Great Britain (excluding Northern Ireland)
  • be a current domestic electricity customer of EDF
  • have a working smart meter for their electricity supply from which EDF can obtain half-hourly readings 
  • not be and not reside with a person(s) who is medically vulnerable and/or dependent on the supply of electricity to the property for any medical reason
  • consent to give EDF half-hourly reads
  • be on single-rate (STD) tariff; and 
  • have a mobile number connected to their account

6. ​​​​​ The Customer agrees to notify EDF if they are no longer Eligible for the Trial. If, at any point throughout the Trial, the Customer is no longer Eligible or moves house, EDF reserves the right to remove the Customer from the Trial.  

Trial and Participation 

7. EDF will contact Eligible Customers before the Trial to confirm their participation. 

8. Each week in which a Challenge (as defined in Clause 9) is running, the Customer will be offered an incentive to reduce the proportion of electricity they consume during the peak, Monday through Friday. The peak will be notified to the Customer and may vary, but it will typically be between 16:00 and 21:00 and last for three consecutive hours each weekday (“Peak Period”). 

9. At the start of each month, EDF will inform the Customer how much they need to reduce the proportion of electricity that they consume in the Peak Period to qualify for the incentive for each week that commences within the calendar month (“the Challenge”). EDF may elect not to run the Challenge every month, meaning no Challenge will be set, and the Customer will not be offered an incentive to reduce the proportion of electricity they consume in the Peak Period. 

10. Throughout the Trial Period and in addition to the Challenge, EDF may notify the Customer that a turn-up event will occur. A turn-up event is where the Customer is informed that they can consume electricity ‘free of charge’ at a specific time (“Turn-Up Event”). EDF will inform the Customer that a Turn-Up Event will be taking place and when it will be. ‘Free of charge’ electricity available in a Turn-Up Event will be awarded by way of credit to the Customer’s account in accordance with Clauses 15 and 16. 

11. EDF is under no obligation to invite the Customer to take part in the Challenge or Turn-Up Events. There is no guarantee on the length of the Challenge or the number of Turn-Up Events.


12. EDF must calculate a baseline for EDF to determine if the Customer has reduced the proportion of electricity consumed in the Peak Period as part of the Challenge. The baseline for any Challenge will be calculated by taking a weekly average of the proportion of electricity the Customer has consumed in the Peak Period from weeks that commence within the previous calendar month (whether or not a Challenge also took place during the previous month) (“Baseline”). EDF will apply a weather correction to the Baseline and reserves the right to apply any other corrections (“Baseline”). Days where a Turn-Up Event takes place will be excluded when calculating the Baseline.

13. If EDF is unable to obtain at least 90% of the Customers’ meter reads when calculating the Baseline, the Customer will not be Eligible to take part in the Challenge.  


14. As part of the Challenge, the Customer will receive an incentive for reducing the proportion of electricity consumed during the peak period. The incentive that the Customer will receive is free electricity (awarded by way of credit to the Customer’s account in accordance with Clauses 15 and 16), which will be available during specified periods on Sundays. EDF will communicate these periods to the Customer. The amount of free electricity, called ("Free Electricity"), will vary depending on the Challenge and how much the Customer reduces the proportion of electricity they consume during the Peak Period. Please note that the Free Electricity periods are separate from the Turn-Up Events.

To ensure that the incentive is used fairly, a 'fair usage' cap will apply, which will vary depending on how many hours of free electricity the Customer has earned. This cap is called the ("Fair Usage Cap") and is subject to change. EDF will communicate the Fair Usage Cap to the Customer at the start of each Challenge month. Any electricity consumed over the Fair Usage Cap during the Free Electricity period will be charged at the unit rate the Customer has an electricity contract for and will not be credited back to the Customer’s account.

15. Free Electricity awarded as part of the Challenge and the ‘free of charge’ electricity awarded as part of Turn-Up Events will be calculated by multiplying the Customers’ total consumption in the allocated Free Electricity period and in the Turn-Up Event by the unit rate of the electricity product the Customer has a contract for (“Payment”) 

16. Any Payment owed to the Customer shall be paid as a credit amount only, which shall be applied to the Customers’ domestic electricity supply account. If EDF makes any overpayment or underpayment to the Customer, EDF may adjust future Payments to reflect this or require reimbursement of any overpayment. Any notified Payments are inclusive of VAT. 

17. EDF is under no obligation to make any Payment to the Customer if EDF are unable to obtain 90% of the Customers’ smart meter readings to calculate the Customers’ electricity usage during the Challenge, Turn-Up Events or Free Electricity periods. 

Data Protection and Publicity 

18. As part of the Trial, EDF may share Customer information, including personal data, with partners, including Loughborough University, The University of Sheffield, the Department for Energy Security and Net Zero and EDF Energy R&D UK Centre Limited (“Partners”), including for research purposes. The Customer information collected and shared with EDF’s Partners may include half-hourly reads and other consumption data, Meter Point Administration Number (MPAN), name, address and contact details. By participating in the Trial, the Customer agrees to have their information collected and shared with EDF’s Partners. EDF’s privacy policy shall apply to any data collected in connection with the Trial, which can be found in our Privacy and Cookie Policy section.

19. By participating in the Trial, the Customer agrees to receive communication from EDF and its Partners via email, SMS, and WhatsApp for trial-related purposes.


20. By participating in the Trial, the Customer warrants that all information submitted by them is true, current, and complete. If any information is found to be fraudulent or incorrectly completed or if EDF has reasonable grounds to believe that the Customer is in breach of these Terms and Conditions or is no longer Eligible, EDF reserves the right to remove the Customer from the Trial and reclaim any payments made under the Trial. 

21. EDF cannot be held responsible for any losses incurred by the Customer during the Trial or participation in the Challenge. This includes any losses resulting from technological or procedural errors, failures, or omissions, as well as any actions or inactions by EDF, its Partners, third parties, or any events beyond its direct control that may affect the provision of the Trial to the Customer.

22. In its sole discretion, EDF reserves the right to reject or revoke the Customer’s participation in the Challenge or Turn-Up Events, withdraw from or pause the Trial, and/or amend the Terms and Conditions without prior notice during the Trial Period. Any decision taken by EDF under Clause 22 shall be effective immediately. EDF shall notify the Customer if amendments are made to these Terms and Conditions. EDF reserves the right to change the Terms and Conditions in compliance with judicial or regulatory rulings and will not be held liable.

23. The courts of England and Wales shall have exclusive jurisdiction to settle any dispute or claim (including non-contractual disputes or claims) arising out of or in connection with this agreement or its subject matter or formation.
