If you're a smart prepayment customer, you'll have been on your new tariff since Friday 1 October.

For prepayment customers who don't have a smart meter: Your new tariff rates will come into effect when you start using your new Shell Energy top-up card, which you'll receive soon. When you receive your new card, it's important to start using it straight away so you're paying the right amount for your energy. Otherwise you'll build up a debt on your account. Please continue topping up with your old card as normal until your new one arrives.
