Car rental in Ireland

Choosing the right rental car can make your Irish road trip more enjoyable

Before You Book

License Requirements

Before booking a rental car in Ireland, ensure you have the proper documentation:

  • A full, valid driving license held for at least 1 year (most companies require 2+ years)
  • EU licenses are accepted without additional documentation
  • Non-EU licenses (including US, Canadian, and Australian) are generally valid for up to 12 months
  • An International Driving Permit (IDP) is recommended if your license is not in English
  • Some rental companies require you to present the credit card used for booking

Important: Bring both parts of your driving license if you have a UK license (photocard and paper counterpart).

Age Restrictions

Age restrictions for car rental in Ireland:

  • Most rental companies require drivers to be at least 21 years old
  • Drivers under 25 typically face additional young driver surcharges (€25-€35 per day)
  • Some premium or larger vehicles may have minimum age requirements of 25 or even 30
  • Many companies have an upper age limit (usually 70-75 years), though some allow older drivers with a fee
  • Younger drivers (21-24) may be restricted to certain car categories

Tip: If you're under 25 or over 70, compare policies across multiple companies as they vary significantly.

Choosing the Right Vehicle

Selecting an appropriate vehicle for Irish roads:

  • Consider sizing DOWN from what you'd typically rent - Irish roads, especially rural ones, can be very narrow
  • Compact or economy cars are ideal for navigating narrow country roads and finding parking in cities
  • Automatic transmissions are available but less common and more expensive than manual (stick shift)
  • If you need an automatic, book well in advance as supply is limited
  • SUVs offer better visibility but can be challenging on narrow roads
  • Check trunk (boot) capacity if traveling with significant luggage

Remember: In Ireland, you'll be driving on the left side of the road with the steering wheel on the right side of the car.

Best Booking Practices

Tips for getting the best deal:

  • Book well in advance, especially for peak season (June-August) and automatic vehicles
  • Compare prices across multiple companies and booking platforms
  • Consider local Irish rental companies, not just international chains
  • Check if your credit card offers rental car insurance coverage before purchasing additional insurance
  • Look for inclusions like unlimited mileage, free additional drivers, and 24-hour roadside assistance
  • Book the shortest rental period needed - daily rates often decrease for longer rentals

Pro Tip: Always read the fine print before booking, especially regarding fuel policies, mileage limits, and cross-border travel (if planning to visit Northern Ireland).

Understanding Insurance Options

Insurance is one of the most confusing and potentially costly aspects of renting a car in Ireland. Understanding your options can save you significant money and stress.

Basic CDW (Collision Damage Waiver)

Almost all rentals in Ireland come with a basic CDW, but it's important to understand its limitations:

  • CDW is NOT full coverage insurance - it only reduces your liability in case of damage
  • With basic CDW, you're still responsible for an "excess" amount (typically €1,000-€3,000)
  • This excess is the maximum amount you'll pay if the car is damaged
  • The rental company will place a hold on your credit card for this excess amount
  • Basic CDW often excludes damage to tires, windows, undercarriage, roof, and mirrors

Important: If you decline the rental company's CDW (e.g., to use credit card coverage), the hold on your card could be €5,000+ (the full value of the car).

Super CDW / Excess Reduction

This additional coverage reduces or eliminates your excess liability:

  • Reduces the excess amount to a small sum (€100-€300) or eliminates it entirely
  • Typically costs €15-€30 per day extra
  • Significantly reduces the hold amount on your credit card
  • May still exclude certain damages (check the fine print)
  • Some companies offer tiered options with varying levels of protection

Our Recommendation: Super CDW is generally worth the extra cost for peace of mind, especially on rural routes where minor scratches from hedges and stone walls are common.

Third-Party Insurance Providers

You can purchase excess insurance from third-party providers, often at lower rates:

  • Companies like Insurance4CarHire, Bonzah, and Allianz offer standalone policies
  • Typically much cheaper than rental company options (e.g., €50 for a week vs. €150+)
  • You'll still need to pay the excess if damage occurs and claim reimbursement later
  • The rental company will still place the full excess hold on your credit card
  • Some rental companies may try to discourage use of third-party coverage

Caveat: With third-party insurance, you'll need to handle the claim process yourself, which can be time-consuming. Consider this against the convenience of the rental company's coverage.

Credit Card Coverage

Some credit cards offer rental car insurance, but there are important caveats for Ireland:

  • Many credit card insurance policies explicitly exclude Ireland (and sometimes Italy)
  • American Express and some premium Visa/Mastercard products may offer coverage in Ireland
  • You must typically decline the rental company's CDW to use credit card coverage
  • Declining CDW means the rental company will place a very large hold on your card
  • Credit card coverage is usually secondary in the US but may be primary internationally

Important: Before relying on credit card coverage, obtain a written confirmation from your card issuer that Ireland is covered, and understand the exact terms and claim process.

Insurance Tips Checklist

  • Read the detailed terms of any insurance before signing
  • Take photos of the car (including undercarriage if possible) before leaving the rental lot
  • Ensure all existing damage is noted on the rental agreement
  • Get a written explanation of what is and isn't covered
  • Understand the procedure in case of an accident
  • Keep a copy of all insurance documentation with you
  • Verify if driving in Northern Ireland is covered (it may require additional insurance)

Watch Out for Hidden Costs

The advertised rate for car rentals in Ireland rarely reflects the final price. Here are the additional costs to be aware of:

One-Way Fees

If you pick up the car at one location (e.g., Dublin Airport) and return it to another (e.g., Shannon Airport), you'll likely face a one-way fee ranging from €50 to €150.

Additional Driver Fees

Adding extra drivers to the rental agreement typically costs €10-€15 per day per additional driver. Some companies offer this for free as part of promotions.

Airport Surcharges

Picking up at an airport location often incurs a premium of 10-20% over the base rate. Consider if a downtown pickup location might be more economical.

Fuel Policies

Be wary of "full-to-empty" fuel policies where you pay upfront for a full tank but return empty. These typically charge premium rates for fuel. "Full-to-full" policies are usually more economical.

Late Return Fees

Returning the car even an hour late can result in an extra day's charge. Some companies offer a grace period (typically 29-59 minutes), but it's best not to rely on this.

GPS/Sat Nav Rental

Rental companies charge €10-€15 per day for GPS systems. Consider using offline maps on your smartphone or bringing your own device instead.

Child Seat Rentals

Child seats are mandatory for children under certain heights/ages and cost €5-€10 per day to rent. Some airlines allow you to check child seats for free.

Toll Handling Fees

Many rental companies automatically charge administrative fees (€3-€5) for processing toll charges, particularly for the M50 barrier-free toll. See our Toll Roads Guide for more information.

Cross-Border Fees

If you plan to drive into Northern Ireland, some companies charge a cross-border fee or require additional insurance. Always declare your intention to cross the border when booking.

Credit Card Surcharges

Some companies add a surcharge (1-3%) for certain types of credit cards or for payments in currencies other than Euro.

Out-of-Hours Fees

Picking up or returning outside of standard business hours may incur an additional charge of €30-€50.

Cleaning Fees

Returning a car that is excessively dirty (inside or outside) can result in a cleaning fee of €50-€100.

True Cost Calculator

When comparing rental options, calculate the true cost by adding up:

  • Base rental rate for the entire period
  • Insurance costs (CDW, Super CDW, etc.)
  • Additional driver fees (if applicable)
  • Young/senior driver surcharges (if applicable)
  • One-way fees (if applicable)
  • Airport/location surcharges
  • Equipment rental costs (GPS, child seats, etc.)
  • Estimated fuel costs (based on your planned itinerary)
  • Estimated toll costs (see our Toll Roads Guide)

This will give you a much more accurate picture of the total cost than just comparing base rates.

Pickup & Return Tips

When Picking Up the Car

  • Document Existing Damage: Take detailed photos/videos of the entire car, including the interior, exterior, wheels, and undercarriage if possible.
  • Check the Damage Report: Ensure all existing damage is correctly noted on the rental agreement. If you spot something that's not documented, point it out to staff.
  • Verify Fuel Level: Confirm the fuel gauge reading matches what's on your agreement (usually full).
  • Test All Features: Check headlights, wipers, indicators, air conditioning, and other features before leaving the lot.
  • Understand the Vehicle: Take time to familiarize yourself with controls, especially if it's a different model than you're used to.
  • Confirm Return Procedure: Get clear instructions on where and how to return the vehicle, especially for after-hours returns.
  • Ask About Emergency Contacts: Get a 24-hour contact number for roadside assistance.

Pro Tip: Take 10-15 minutes to adjust your seat, mirrors, and get comfortable with the vehicle before leaving the rental location. This is especially important if you're not used to driving on the left.

When Returning the Car

  • Refuel Near the Return Location: If your policy is "full-to-full," refill the tank at a station close to the return location and keep the receipt.
  • Allow Extra Time: Arrive early to handle any unexpected issues or paperwork.
  • Document the Condition: Take photos/videos of the car upon return as evidence of its condition.
  • Get a Final Inspection: If possible, have a staff member inspect the car while you're present and provide written confirmation that it was returned without damage.
  • Check for Personal Items: Thoroughly check all compartments, trunk, and under seats for personal belongings.
  • Return Keys as Instructed: For after-hours returns, follow the company's procedure exactly.
  • Keep All Documentation: Hold onto your rental agreement, fuel receipts, and return confirmation for at least 60 days.

Important: Monitor your credit card statements after the rental to ensure no unexpected charges appear. If they do, contact the rental company promptly with your documentation.

Common Problems & How to Avoid Them

Damage Claims Disputes

Problem: Being charged for damage you didn't cause.

Solution: Thoroughly document the car's condition before and after with dated photos/videos. Get a signed return receipt confirming the condition.

Unexpected Insurance Charges

Problem: Finding extra insurance charges on your final bill that weren't clearly explained.

Solution: Get all insurance costs in writing before signing the rental agreement. Keep a copy of any quotes or promotional offers.

Credit Card Holds

Problem: Excessive or unexpected holds on your credit card limiting your available funds.

Solution: Ask about the exact hold amount when booking and confirm at pickup. Use a credit card with a high limit specifically for the rental.

M50 Toll Penalties

Problem: Receiving penalty charges for unpaid M50 tolls.

Solution: Understand the rental company's toll policy in advance. Some automatically charge tolls to your card, while others expect you to pay yourself. See our M50 Toll Guide for details.

Rental Car Breakdowns

Problem: Vehicle breakdowns in remote areas.

Solution: Save the rental company's roadside assistance number in your phone. Understand what's covered in case of a breakdown before departing.

Wrong Fuel Type

Problem: Putting petrol in a diesel car or vice versa.

Solution: Double-check the fuel type (usually noted near the fuel cap or on a sticker on the dashboard). This mistake can be very costly as it's typically not covered by insurance.

Currency Conversion Charges

Problem: Being charged in your home currency at unfavorable exchange rates.

Solution: Always opt to pay in the local currency (Euro) rather than accepting the rental company's currency conversion.

After-Hours Return Issues

Problem: No staff present to confirm the car's condition upon return.

Solution: Take time-stamped photos/videos showing the car's condition, fuel level, and mileage. Follow all after-hours return instructions exactly.

Frequently Asked Questions

Can I use my US/Canadian/Australian license to drive in Ireland?

+

Yes, visitors to Ireland can use their valid foreign driver's license for up to 12 months. Licenses from the US, Canada, Australia, and most other countries are accepted. However, if your license is not in English, an International Driving Permit (IDP) is recommended as a translation document. An IDP must be obtained in your home country before traveling.

Should I rent an automatic or manual transmission car?

+

If you're comfortable driving a manual (stick shift) transmission, it's typically the less expensive option in Ireland. Automatic transmissions are available but are usually 20-30% more expensive and less common in rental fleets.

For drivers not used to driving on the left side of the road, an automatic transmission can reduce cognitive load since you won't need to adjust to both a different side of the road and shifting with your left hand. This can be particularly helpful when navigating roundabouts and narrow rural roads.

If you require an automatic, book well in advance as they are in limited supply, especially in smaller locations or during peak tourist season.

Can I drive a rental car from the Republic of Ireland to Northern Ireland?

+

Most rental companies allow driving between the Republic of Ireland and Northern Ireland, but you should always declare your intention to cross the border when booking. Some companies charge a cross-border fee or require additional insurance coverage.

Important things to note when crossing the border:

  • Speed limits change from kilometers per hour (km/h) in the Republic to miles per hour (mph) in Northern Ireland
  • Currency changes from Euro (€) to Pound Sterling (£)
  • In case of an accident in Northern Ireland, different procedures may apply
  • Any traffic fines or penalties incurred in Northern Ireland are handled differently from those in the Republic

There are no physical border checks between the Republic and Northern Ireland, so you may not notice when you cross the border except for changes in road signs.

What's the best credit card to use for car rental in Ireland?

+

The ideal credit card for car rental in Ireland would have:

  • A high credit limit to accommodate the security deposit hold (potentially €1,000-€3,000)
  • No foreign transaction fees
  • Rental car insurance coverage that specifically includes Ireland (rare, but some premium cards offer this)

Always check with your credit card company before relying on their insurance coverage in Ireland, as many specifically exclude Ireland (and sometimes Italy). If your card does offer coverage in Ireland, request written confirmation of this and bring it with you.

Most rental companies require a credit card (not a debit card) in the main driver's name for the security deposit. The card used for the deposit typically must be the same one used to pay for the rental.

How do I deal with M50 toll charges in a rental car?

+

The M50 toll around Dublin is barrier-free, meaning there are no toll booths to stop at. Cameras record your license plate, and payment must be made by 8 PM the following day.

Rental car companies handle M50 tolls in different ways:

  • Some automatically pay the toll and charge it to your credit card, often with an additional administrative fee (€3-€5 per toll)
  • Others expect you to pay the toll yourself via the official website (eFlow.ie), by phone, or at certain retail outlets
  • Some rentals come with electronic toll tags that cover all toll roads in Ireland

It's crucial to ask about the rental company's specific toll policy when picking up the car. Failure to pay M50 tolls can result in significant penalties (€40-€100+ per unpaid toll), which will be charged to your credit card by the rental company.

For more detailed information, see our M50 Toll Guide.

What should I do if I have an accident in a rental car?

+

If you're involved in an accident with a rental car in Ireland:

  1. Ensure safety: Move to a safe location if possible and check if anyone is injured
  2. Call emergency services if needed: Dial 112 or 999 for police, ambulance, or fire
  3. Exchange information: Get names, addresses, phone numbers, and insurance details from all parties involved
  4. Document everything: Take photos of all vehicles, damage, the accident scene, and any relevant road signs or conditions
  5. Contact the rental company immediately: Use their emergency number provided with your rental agreement
  6. File a police report: For any accident involving injuries or significant damage, report to the Gardaí (Irish police)
  7. Do not admit fault: Even if you believe you were responsible, avoid admitting liability
  8. Complete an accident report form: The rental company will provide this either on-site or at their location

Keep all documentation related to the accident, including police reports, witness statements, and the accident report form. You may need these for insurance claims or disputes.

About Rental Companies in Ireland

Irish Roads does not recommend specific rental companies, as experiences can vary greatly depending on location, season, and individual circumstances. However, we can provide some general information about the types of rental companies operating in Ireland.

International Chains

Major international rental companies operating in Ireland include Hertz, Avis, Budget, Enterprise, Europcar, and Sixt. These typically offer:

  • Larger, newer fleets with diverse vehicle options
  • Multiple locations, including all major airports and cities
  • More standardized service and policies
  • Loyalty programs that may offer benefits
  • Often higher base prices but may have international promotions

Irish National Companies

Irish-owned companies like Dan Dooley (now part of Enterprise), Irish Car Rentals, and Dooley Car Rentals typically offer:

  • Competitive rates, sometimes lower than international chains
  • Staff with good local knowledge
  • Presence at major airports and cities
  • Familiarity with Irish driving conditions and requirements
  • Policies designed with tourists in mind

Budget/Discount Providers

Budget operators like Easirent, Advantage, and various local companies offer:

  • Lower base rates but often more add-on fees
  • Older fleet with fewer premium options
  • Limited locations, primarily at airports
  • Potentially stricter terms and conditions
  • May have less flexibility with issues or special requests

These companies can offer good value but require careful reading of all terms and policies.

Aggregators & Brokers

Booking platforms like AutoEurope, Discover Cars, and RentalCars.com:

  • Allow you to compare rates across multiple companies
  • Sometimes offer exclusive deals or package rates
  • Provide an additional layer of customer service
  • May offer their own insurance options
  • Reviews often available to help compare companies

When booking through an aggregator, you're still renting from the actual rental company, not the booking platform.

Tips for Choosing a Rental Company

  • Research recent reviews specific to the location where you'll be renting
  • Compare total costs including all fees, not just the advertised base rate
  • Check the company's policy on cross-border travel if planning to visit Northern Ireland
  • Verify their hours of operation, especially for pickup and return
  • Consider the convenience of the pickup/return location relative to your travel plans
  • Look for transparent policies regarding insurance, fuel, and additional charges
  • Check if they offer 24-hour roadside assistance
