What happens if I top up using another supplier's key or card?

Traditional prepayment meters are programmed by the key or card that you use to top up. This means that if you top up using a key or card from a previous supplier, you'll still be paying their unit rates and standing charges.

You'll also miss out on other important things too, like our friendly credit hours and emergency credit.

If your old key or card expires, you also risk losing power.

If you've switched to us, but have not received a top key or card for your prepayment meter, or your existing key/card has stopped working, just get in touch.

In an emergency, please email emergency@octopus.energy
