If you want to cancel your switch to us, you should let us know straight away. What happens next depends on whether we've started supplying you with energy or not. If we haven't yet started supplying you with energy – and you're still within your 14-day cooling off period Just sit back and relax – you don't need to do anything. You'll stay put with your current supplier and we'll take care of the cancellation for you. We'll be back in touch to let you know when it's done. If we've already started supplying you with energy and you’re still within your 14-day cooling off period You have three options to choose from: 1. Stay with EDF and upgrade your energy plan If you want to do this, simply give us a call on 0333 009 7114 2. Go back to your previous energy supplier Please contact your previous supplier if you’d like to switch back to them. You should go back on equivalent terms and conditions. 3. Choose a new energy supplier Please choose a new tariff with another supplier. You’ll have a new energy plan, contract and terms and conditions. We'll also write to you to let you know about these options. While you decide what to do, you'll stay on the tariff you chose when you joined EDF and you'll need to cover the cost of any energy you use during your time with us. You have 15 working days to make a decision from when we have sent you information about your cancellation. If you don't pick one of these three options or we don't hear from you within this time, you'll stay with EDF and move on to our deemed tariff. This means your energy prices can go up or down. You can check what our deemed prices are in the letter we send you outlining your choices.
