It doesn’t matter who supplies your gas or electricity – it all comes into your home through the same pipes, ducts, cables and wires. All switching means, is that the supplier providing it changes. When you make the decision to switch, your new supplier will sort out all the details with your existing one – they’ll even break the news that you’re leaving.
Your new energy supplier will send you paperwork setting out your new tariff, as well as confirming details like your payment method and dates. If they aren’t correct, then make sure you let them know. You have 14 days to change your mind, so if you think you’ve made a mistake – it’s not the end of the world.
Check whether there’s an exit fee for leaving your existing supplier – especially if you decide to leave partway through a fixed rate contract. If there is an exit fee, then you’ll need to think about whether it’s actually worth waiting until your agreement expires.
As part of new Ofgem rules, your energy supplier has to tell you that your contract is due to end 42-49 days before it does. These end of contract days are your opportunity to look for a better deal. If you do decide to switch during the last 49 days of your contract, then you can’t be charged an exit fee.
