Yes. For most offers on our website you will be required to leave a security deposit when you collect the car. The deposit amount will be temporarily blocked on / taken from the main driver’s credit card and held for the duration of the rental.
As long as you bring the car back undamaged at the end of the rental, the money will be unblocked / returned.
If the main driver’s credit card does not have enough available funds for the deposit, you may not be allowed to take the car - or the counter staff may insist that you buy additional cover from them.
This is standard practice with all car hire companies.
