Most major car hire companies at Dublin Airport accept cash deposits, but the amount, currency, and conditions vary by provider
If you're renting a car at Dublin Airport and want to pay your deposit in cash rather than by card, you have options — but you need to know which companies take cash, what they require, and what happens to your money after you return the vehicle. The largest operators at Dublin Airport (Hertz, Avis, Budget, Enterprise, and Europcar) all accept cash deposits, though each has different rules about how much you must leave, whether they take euros or other currencies, and how they handle the refund.
Cash deposits serve the same purpose as a credit card hold: they find the rental against damage, fuel charges, or tolls you incur during your rental period. The deposit is not a payment for the rental itself — you still pay the rental fee separately, usually by card or cash at pickup. Understanding the deposit rules before you arrive at the counter saves you from surprises and protects your cash.
Key Takeaways
- Hertz, Avis, Budget, Enterprise, and Europcar all accept cash deposits at Dublin Airport, but the required amount ranges from €500 to €2,000 depending on the vehicle class.
- Most companies require deposits in euros; some accept other currencies but may explore unfavorable exchange rates or refuse non-euro cash entirely.
- Your deposit is held in a separate account and returned within 5 to 10 business days after you return the car, provided there are no damage claims or outstanding charges.
- If you damage the vehicle or incur tolls, the company deducts the cost from your deposit before returning the remainder.
- Bringing a credit card as backup is wise, because some companies may refuse a cash deposit if you cannot also provide a valid payment card for the rental fee itself.
Deposit amounts and vehicle categories at Dublin Airport
The deposit you must leave depends on the size and type of vehicle you're renting. Economy and compact cars typically require €500 to €800 in cash. Mid-size sedans and small SUVs usually sit at €800 to €1,200. Larger SUVs, vans, and premium vehicles can require €1,500 to €2,000 or more. These amounts are not fixed across all companies — Hertz may ask for €700 for an economy car while Avis asks for €600 for the same class — so contact your rental company directly before arrival to confirm the exact figure for your vehicle.
The deposit covers potential damage to the vehicle, missing or damaged parts, fuel shortfall if you don't return the car full, and tolls or parking fines incurred during the rental. It is not a damage waiver or insurance premium. If you return the car in perfect condition, with a full tank, and no toll charges, you get the full amount back. If the company finds damage or charges accrue, they deduct those costs and return what remains.
Currency and payment method requirements
All major car hire companies at Dublin Airport accept euro cash deposits. If you arrive with pounds sterling, US dollars, or another currency, most will refuse it outright or offer an exchange rate so poor that it costs you money. Bring euros if you plan to pay your deposit in cash. ATMs are available throughout Dublin Airport, and the exchange rates at airport ATMs are typically better than those offered by car hire counters.
Some companies require you to provide a valid credit or debit card even if you're paying the deposit and rental fee in cash. This card is not charged — it serves as a backup payment method in case additional charges arise after you leave (such as a toll notice arriving weeks later). If you have no card, ask the rental agent whether they will accept a cash deposit alone. Policies vary, and some companies will not rent to customers without a card on file.
How deposits are held and returned
When you hand over your cash deposit at the Dublin Airport counter, the rental agent counts it, records the amount on your rental agreement, and places it in a separate account or safe. This money is not mixed with the company's operating funds. You receive a receipt showing the deposit amount and the date. Keep this receipt — you will need it to track the refund if questions arise later.
After you return the car, the rental company inspects it for damage, checks the fuel level, and reviews any toll or parking charges. This inspection typically takes 24 to 48 hours. Once the inspection is complete and no additional charges are found, the company processes your refund. Most companies return cash deposits within 5 to 10 business days, though some take up to two weeks. The refund is usually paid in cash at the rental counter if you're still in Dublin, or by bank transfer to an account you provide if you've left Ireland.
Damage claims and deductions from your deposit
If the rental company identifies damage to the vehicle during the return inspection, they photograph it, estimate the repair cost, and deduct that amount from your deposit. Common charges include dents, scratches, cracked windows, and interior stains. The company must provide you with photographic evidence and a written estimate of the repair cost. If you disagree with the damage assessment or the repair estimate, you have the right to dispute it — ask for a copy of the damage report and contact the rental company's customer service department in writing.
Fuel charges also come from your deposit. If you return the car with less than a full tank, the company charges you for the missing fuel at a rate higher than the market price (typically €1.50 to €2.00 per liter). Tolls and parking fines incurred during your rental are deducted as well. To avoid these charges, return the car with a full tank and review your rental agreement for any toll or parking restrictions before you drive away from the lot.
Comparing deposit policies across major Dublin Airport providers
| Company | Typical Deposit (Economy Car) | Currency Accepted | Refund Timeline | Card Required |
|---|---|---|---|---|
| Hertz | €700–€800 | Euros | 5–10 business days | Yes, as backup |
| Avis | €600–€750 | Euros | 5–10 business days | Yes, as backup |
| Budget | €650–€800 | Euros | 7–14 business days | Yes, as backup |
| Enterprise | €600–€750 | Euros | 5–10 business days | Yes, as backup |
| Europcar | €700–€900 | Euros | 7–14 business days | Yes, as backup |
These figures are typical but not may provide. Deposit amounts change based on vehicle availability, seasonal demand, and your driving record. Always confirm the exact deposit amount with your rental company at least one day before pickup. If you're booking online, the deposit amount should appear in your confirmation email. If it doesn't, call the Dublin Airport location directly.
Practical steps for paying a cash deposit at Dublin Airport
Arrive at the car hire counter with your euros in cash, your rental confirmation, your passport, and a valid driver's license. Have your credit or debit card ready as well, even if you plan to pay the deposit in cash — most companies require it. Count your cash before handing it over and ask the agent to count it in front of you. Request a written receipt showing the deposit amount, the date, and the rental agreement number. Do not leave the counter without this receipt.
If the rental agent tells you the deposit amount is higher than what you were quoted online or by phone, ask for an explanation in writing. Deposits can increase if you're renting a larger vehicle than originally booked or if your driving record raises the company's risk assessment, but you have the right to know why. If you don't have enough cash, ask whether the company will accept a partial cash deposit and charge the remainder to your card. Some will; others will not.
What to do if your deposit refund is delayed
If more than two weeks have passed since you returned the car and you haven't received your deposit refund, contact the rental company's customer service department. Provide your rental agreement number, the date you returned the vehicle, and the amount of your deposit. Ask for a written explanation of any charges deducted and a timeline for the refund. Most delays are due to pending toll or parking fine notices that arrive after you've left Ireland — these can take weeks to process.
If the company refuses to refund your deposit or deducts an amount you believe is unjustified, you can file a complaint with the company's head office and, if necessary, pursue the matter through small claims court or your credit card company (if you provided a card as backup). Keep all documentation: your rental agreement, the deposit receipt, photographs of the car at pickup and return, and any correspondence with the rental company.
Frequently Asked Questions
Can I pay my rental fee in cash and my deposit by card, or vice versa?
Yes. You can pay the rental fee in cash and the deposit by card, or pay the deposit in cash and the rental fee by card. The two payments are separate. However, most companies require a valid card on file regardless of how you pay, so you'll likely need both payment methods available.
What happens if I return the car damaged and my deposit doesn't cover the repair cost?
The rental company will charge your backup credit card for the amount that exceeds your deposit. This is why providing a card is important even if you pay the deposit in cash. If you have no card and the damage exceeds your deposit, the company may pursue the debt through collection or legal action.
Can I get my deposit back in a different currency than I paid it?
Most companies refund deposits in the same currency you paid them. If you paid in euros, you'll receive euros back. If you need the refund in another currency, ask the rental agent at return time whether they can arrange a currency exchange or bank transfer to your home country account.
Do I need to bring my deposit receipt to return the car?
You don't need it to return the car, but bring it anyway. The receipt proves the amount you deposited and helps the rental agent locate your account quickly if there are any questions about charges or refunds.
Is my cash deposit insured if the rental company goes out of business?
No. Your deposit is held by the rental company, not in a separate trust account protected by law. If the company fails financially, your deposit may be at risk. This is another reason to keep your credit card as a backup — charges to your card are protected by your card issuer's dispute process.
