The advanced payment is collected by Direct Debit 14 days after the agreement is executed (the date of vehicle delivery).
Your first rental may be taken the same month, but this depends on the date of delivery and the chosen date for direct debits to be taken.
Example below:
The first monthly hire payment will be applied the next month following delivery (If delivered in March, the first payment will be due in April).
In some circumstances it is possible that the first monthly payment may be collected before the advance payment. If you take delivery on 29th March and selected a payment date of the 8th, the first monthly payment will be taken by Direct Debit on the 8th April . The advanced payment would then be taken on the 12th April.
