Can I choose the repayment amount?

No, automated Layby payments will only ever take the minimum repayment for that payment. If you wish to make a larger payment, you can do so via the 'Credit Card' or 'Stored credit card' tabs in your PPQ account and this will give you the options to adjust your payment amount. Once a manual payment has been made, the next automated Layby payment date will be based on your original Layby payment plan.
