1. Sign up to Octopus Energy here. You must be an Octopus Energy customer to join one of our smart tariffs. Switch to an interim tariff and you’ll then be moved across to your smart tariff of choice.

2. Have a smart meter Octopus Energy can connect to. If you don’t already have a smart meter, Octopus Energy can arrange to have one installed. Please see their website for more information.

3. Confirmation email. Once Octopus Energy have received half-hourly readings from your smart meter, which takes up to 14 days, they'll send you an email asking you to accept the Terms and Conditions of your new smart product to complete your switch. You must accept these T&Cs before your switch can be completed.
