Usually, you will be powered by your new supplier within 21 days. This includes a cooling off period, during which you are free to change your mind about switching without being charged any additional fees.

Do I need to contact my new energy supplier?

After switching energy deal, you don’t need to call your new or old suppliers. Your new energy supplier will get in touch with a welcome pack, to outline the contract you’ve agreed, and to provide the dates that the switch will be finalised. They will also ask you to take a meter reading, which they’ll pass on to your old supplier to ensure your final bill is accurate.

Will I be billed twice during my switch?

You won’t be billed multiple times when switching energy supplier. The companies involved will agree a switchover date and keep everyone informed of this, ensuring final billing dates and starting billing dates don’t overlap. It’s a good idea to check that you’ve cancelled any old direct debit payments once you change supplier to be completely certain that you won’t be overcharged.

Can I change my mind about switching supplier?

Even if you cancel during the cooling off period, you won’t be left without power in your home.

Can I switch energy suppliers again?

You can switch gas or electricity suppliers every 28 days, but some energy deals have cancellation charges called exit fees. These are usually if you’re on a fixed term plan, using a fixed tariff rate until a specific date. However, during the final 49 days of your contract, you can switch without paying an exit fee, and it’s a good idea to compare and switch at the end of your contract. For some households, it might be beneficial to switch before your contract ends. Be mindful of the exit fee and weigh this up against the savings you could make from switching.
