What is a security deposit and how much is it?

A security deposit is a sum that the car rental company block on your credit card at the start of your rental to protect them from any possible costs of the rental car.

It is normally done so that a sum, usually an amount to cover the excess and petrol costs, is blocked on the driver’s credit card. The deposit ensures the car rental company that customers can pay for any damage to the car that arises, or the cost of filling petrol. If the rental car is returned in original condition, then  the full amount is placed back on the credit card at the end of the rental. The deposit varies and depends on the size of the vehicle, driver age, car rental company, rental period and pickup location.

The size of the sum is derived in step 2 in the Rate details section of your booking, and also in your rental agreement.
