Quick answer
The deposit and the insurance excess are two different things. The deposit is a refundable amount held on your card at pickup and typically released after you return the car clean, fine-free and undamaged. The excess, also called the deductible, is the amount you pay toward repairs if you are at fault in an accident, even with insurance. So the deposit is temporary and comes back, while the excess is only a real cost if you have an at-fault claim. Both vary by company and car class.
What is a car rental security deposit?
The security deposit is a refundable amount that the company holds on your card at pickup. It is typically released after you return the car clean, fine-free and undamaged. Think of it as temporary money, tied up on your card from pickup until the company releases it.
It can come in one of two forms. A pre-authorisation hold sets the amount aside on your card rather than taking it, while an actual charge takes the amount and returns it later. How much it is varies by company and car class, so check your contract for the amount and for which form it takes, rather than relying on a figure you have heard elsewhere. For deposits in general, see our car rental deposit guide.
What is the insurance excess, or deductible?
The insurance excess, also called the deductible, is the amount you pay toward repairs if you are at fault in an accident. It applies even when the car is insured. Having insurance on the rental does not mean you pay nothing after an at-fault accident: the excess is the part that is yours.
That makes it very different from the deposit. The deposit is temporary and comes back. The excess is only a real cost if you have an at-fault claim, and if you never have one, you never pay it.
Like the deposit, the amount varies by company and car class. A full-cover or CDW upgrade reduces or removes it (more on that below). Check your contract for how a claim, and the excess, would be handled before you drive away.
Deposit vs excess: side by side
The two are easy to mix up: both are sums of money tied to your rental, and both vary by company and car class. But they work differently and come into play at different moments, as the table shows.
| Question | Deposit | Insurance excess |
|---|---|---|
| What is it? | DepositA refundable amount held on your card at pickup | Insurance excessThe amount you pay toward repairs if you are at fault in an accident, even with insurance |
| When does it come into play? | DepositAt pickup, as a pre-authorisation hold or an actual charge. It is typically released after you return the car clean, fine-free and undamaged | Insurance excessAfter an accident in which you are at fault |
| Is it a real cost? | DepositNo. It is temporary and meant to come back | Insurance excessOnly if you have an at-fault claim |
| What changes the amount? | DepositThe company and the car class | Insurance excessThe company and the car class. A full-cover or CDW upgrade reduces or removes it |
Both amounts vary by company and car class. Check your own contract for the figures that apply to you.
Does full cover or CDW remove the excess?
A full-cover or CDW upgrade reduces or removes the excess. How far it goes can vary by company, so ask for the excess with and without the upgrade, and for the price of the upgrade, before you decide. Check the contract for exactly what the upgrade covers.
Because the excess is only a real cost after an at-fault claim, that is when a lower excess makes a difference. Whether the upgrade is worth its price is your call: weigh what it costs against the size of the excess it takes away.
Whether the upgrade also changes the deposit is a separate question, and this guide cannot say what every company does, so ask about both and get the answer in writing. For the insurance side of a rental in more detail, see our car rental insurance guide.
What to check before you sign
Because both amounts vary by company and car class, the figures that count are the ones in your own contract. For real per-company fee data to compare against, see our fee transparency report, and try the fees and true-cost tool too. Before you sign, ask:
- How much is the deposit, and is it a pre-authorisation hold or an actual charge?
- When is the deposit released after you return the car, and on what conditions?
- How much is the excess for the car class you are renting?
- How much does a full-cover or CDW upgrade reduce the excess, and does it remove it altogether?
- How and when would an excess be collected if you were at fault in an accident?
Ask for the answers in writing, so you have the company's own terms to quote if anything is disputed later.
If your deposit does not come back
The deposit is meant to be released after you return the car clean, fine-free and undamaged. If it is not, there is a clear route to follow, and our deposit-back tool builds the letter and the escalation ladder for you. In outline:
- 1Raise it with the company first, in writing, quoting their own terms.
- 2If the deposit was taken as a card charge, ask your bank for a chargeback. A hold that has not been captured can simply be released.
- 3At the time of writing, a Dubai-licensed company answers to Dubai's Department of Economy and Tourism (DET): file a Dubai Consumer complaint or call 600 54 5555.

Frequently asked questions
What is the difference between a security deposit and the insurance excess?
The deposit is a refundable amount held on your card at pickup and typically released after you return the car clean, fine-free and undamaged. The excess is the amount you pay toward repairs if you are at fault in an accident, even with insurance. The deposit is temporary; the excess is only a real cost if you have an at-fault claim.
Do I get my security deposit back on a Dubai car rental?
It is meant to be refundable, and is typically released after you return the car clean, fine-free and undamaged. Check your contract for when and how it is released. If it does not come back, start with the company in writing, then use the deposit-back tool on this site.
Is the deposit a charge or a hold?
It can be either: a pre-authorisation hold or an actual charge on your card. A hold that has not been captured can simply be released, while a card charge is the case where you would ask your bank for a chargeback. Ask which one applies before you sign.
Is the insurance excess the same as a deductible?
Yes. The excess is the deductible: the amount you pay toward repairs if you are at fault in an accident, even though the car is insured. It varies by company and car class.
Do I still pay the excess if I have insurance?
Yes, if you are at fault in an accident, because the excess applies even with insurance. If you never have an at-fault claim, it never becomes a cost. A full-cover or CDW upgrade reduces or removes it.
Does full cover or CDW remove the excess, and what about the deposit?
A full-cover or CDW upgrade reduces or removes the excess. How far it goes can differ, so ask for the excess with and without it. Whether it also changes the deposit is a separate question to put to the company, so ask about both and get the answer in writing.
How much is the deposit or the excess on a Dubai car rental?
Both vary by company and car class, so no single figure applies. Check your contract for the amounts that apply to you. For real per-company fee data, see our fee transparency report.
What can I do if my deposit does not come back?
Raise it with the company first, in writing, quoting their own terms. If the deposit was taken as a card charge, ask your bank for a chargeback. At the time of writing, a Dubai-licensed company answers to Dubai's Department of Economy and Tourism (DET), so you can file a Dubai Consumer complaint or call 600 54 5555.
