Avoid Higher Costs: A Guide to EDF’s Out of Contract Rates

A man with glasses is looking at a piece of paper.

If your business’s fixed-term electricity contract with EDF has ended, and you haven’t renewed or switched suppliers, you’ll automatically move onto their Extended Supply Rates. These rates are significantly higher than fixed-term tariffs, ensuring continuity of supply but at a premium cost.


In this blog, we’ll explore EDF’s current Extended Supply Rates, explain their potential impact, and show you how The Smart Energy Company can help you secure a better deal.

What Are EDF Extended Supply Rates?


EDF applies Extended Supply Rates to businesses whose fixed-term contracts have ended without renewal or a supplier switch. These rates include:


  • Unit Rates (p/kWh) which vary based on time of use and location.


  • A Standing Charge (p/day) applied per meter.


These rates vary depending on your meter type and location, with charges higher than fixed-term agreements.
