No, sorry. You can only pay the total amount you owe on your most recent bill when you pay by credit card over the phone or online.
But there’s a great payment option called LevelPay if you want more control over how you pay your bill. By signing up to LevelPay, you’ll avoid unexpected spikes by evening out your payments.
You can pay a set amount each week, fortnight or month. It’s a great way to budget, with no surprises.
