Is there a maximum amount of funds I can use to pay my bill with ZIPZERO?

No, there is no limit to what you can pay, but there is a £50 limit to what you can earn each month towards your bills by scanning your receipts.

You decide what you do with your Available Funds, just remember that they stay available for 90 days. You can use them to pay a single bill in full or split the amount to cover several bills.
