Tap on the menu and then choose 'Balance & payments'.
You'll see a date for your next payment. You can change this date to one that suits you.
If your next payment is due in 10 days or sooner, your app will let you know that it's too close to change it, for now. You'll be able to change it once the next payment has been made.
You can also change your bank details in your account. Tap on 'Change payment details' and type in the new account name, account number and sort code.
