How long does it take to switch energy supplier?

21 days from the date you apply to switch is the industry standard for switching energy supplier.

The “Energy Switch Guarantee” ensures that switching supplier takes no longer than 21 days, including a 14 day cooling off period, whether you switch to one of the Big Six suppliers – British Gas, SSE, EDF Energy, Npower, Scottish Power and E.ON – or a smaller supplier, such as Octopus Energy, Shell Energy, So Energy and Bulb.

All switching applications come with a mandatory 14-day cool-off period should you wish to cancel your application and revert back to your original supplier.

The switching process itself is very straightforward and is dealt with by your old and new suppliers – the only thing you need to do is provide your old supplier with a final meter reading to close your account.
