See this article for instructions on how to make payments early.
If you need to reschedule payments to a later date (e.g. to align with your payday) our Customer Experience team can help with this. Get in touch with us here and we can push out your payment date by up to a week, as long as the instalment payment is not due today or the date has already passed.
Please note you must give at least 48 hours' notice for changes of this type and this can only be done once per order.
