Updated on 30/09/2020: We have recently changed Smart PAYG. See this guide for info on the latest changes. Still got a question about the new Smart PAYG? Create your topic here to get it asked. The answer will help you and others!
We register the payment cards to your smart meters on our end so you don't need to do anything!
As soon as you've received the card, you can start topping up. The top ups will automatically be added to your balance so no need to insert the card into the meter afterwards.
