Smart meters will make prepay as easy as pay-as-you-go on your mobile or tablet. If you choose smart prepay, you should be able to conveniently see how much credit you have left on your in-home display, using an app, over the phone, or via text. Top-up in person at your local store/outlet, without any need to put a key or card back into a meter. Payments will automatically be added to your account and you’ll always be able to top-up with cash.
