What do I need to know if I want to switch energy suppliers?
If you want to switch energy suppliers, start by finding out whether your current supplier will charge an exit or cancellation fee. You’ll find this information on your energy bill. If they do, you’ll need to work out whether you’ll still save money by switching.
If the exit charge outweighs any savings you might make, wait until you receive a notice from your supplier 42-49 days before your contract is due to end – if you decide to switch during this time, you cannot be charged for leaving. Your supplier should send you a letter highlighting this notice period.
