What you need to rent a car in Ireland

To rent a car in Ireland, you must be at least 21 years old (some companies require 25), hold a valid driving licence from your home country, and have a credit card in your name for the deposit. If your licence is not in English, bring an International Driving Permit alongside it — Irish rental companies will ask for both. You will also need a form of ID that matches your credit card, usually a passport.

The rental company will place a hold on your credit card for a security deposit, typically €500 to €1,500 depending on the car category. This is not a charge — it is released when you return the vehicle undamaged. If you damage the car, the company deducts repair costs from the hold. Some companies offer damage waiver insurance that reduces or removes your liability for minor damage; this costs extra but can save money if you are unfamiliar with Irish road conditions or driving on the left.

You will need to provide proof of insurance. Most rental companies include basic third-party liability coverage in the rental price, but this covers only damage you cause to other vehicles or property, not damage to the rental car itself. Collision damage waiver (CDW) and theft protection are optional add-ons. Check whether your personal car insurance or credit card already covers rental vehicles — many do — before paying for duplicate coverage.

Key Takeaways

  • You must be at least 21 (often 25), hold a valid driving licence and International Driving Permit if your licence is not in English, and have a credit card for the security deposit.
  • The rental company will hold €500 to €1,500 on your credit card as a deposit; this is released when you return the car undamaged.
  • Basic third-party liability is usually included, but collision and theft coverage cost extra and may already be covered by your personal insurance or credit card.
  • Irish rental companies are concentrated in Dublin, Cork, Shannon, and Belfast; booking in advance online is usually cheaper than booking at the counter.
  • Return the car with a full fuel tank and document any existing damage with photos before you drive away from the lot.

Where to rent a car in Ireland

The major international rental chains — Hertz, Avis, Budget, and Enterprise — operate at Dublin Airport, Cork Airport, Shannon Airport, and Belfast International Airport. Smaller local companies like Europcar and Dan Dooley also have desks at these airports and in city centres. Airport locations are convenient but charge airport fees on top of the daily rate, sometimes adding 15 to 25 percent to your total cost.

City centre branches in Dublin, Cork, Galway, and Limerick do not charge airport fees and are often cheaper for multi-day rentals. If you are flying into Dublin but do not need the car when ready, collecting it from a city centre location the next day can save money. Some companies offer one-way rentals — you pick up in Dublin and drop off in Cork or Belfast — but these carry a surcharge that varies by company and distance.

Book online directly through the rental company's website or through comparison sites like Rentalcars.com, Kayak, or Costco Travel (if you are a member). Online rates are almost always lower than walk-up rates at the counter. Booking at least a week in advance gives you better pricing and guarantees availability during peak season (June to August).

Understanding fuel and mileage policies

Most Irish rental cars are rented on a full-to-full fuel basis: you collect the car with a full tank and must return it with a full tank. If you return it empty or partially full, the company charges you for fuel at a rate significantly higher than petrol station prices — sometimes double. Fill up at a petrol station within a few kilometres of the rental office before you return the car.

Mileage is usually unlimited on standard rentals, but budget companies sometimes impose daily mileage limits (for example, 100 km per day with overage charges of €0.25 per km). Check the rental agreement before you book. If you plan to drive from Dublin to Galway and back, or to explore the Ring of Kerry, unlimited mileage is essential.

Diesel cars are common in Ireland and use less fuel than petrol equivalents, which can reduce your fuel costs over a week-long rental. Petrol cars are easier to find at smaller rental locations. Hybrid and electric vehicles are available at major airports but at a premium price and with limited range for rural driving.

Driving in Ireland: what renters need to know

Ireland drives on the left side of the road, and the steering wheel is on the right side of the car. If you are from a country that drives on the right, this takes active concentration for the first few hours. Many rental companies offer a brief orientation; take it. The first time you navigate a roundabout or a narrow country lane on the left is not the time to learn the layout of the controls.

Speed limits are posted in kilometres per hour: motorways allow 120 km/h, national roads 100 km/h, and regional roads 80 km/h. Towns and villages have 50 km/h limits. Speed cameras are common on motorways and national roads; fines are issued by post to your home address weeks later. Seatbelts are mandatory for all passengers, and mobile phone use while driving is illegal.

Irish roads outside major cities are narrow, often single-track with passing places. Hedgerows and stone walls mean you cannot see oncoming traffic until you are very close. Drive slowly on regional roads, especially in rain or fog. Petrol stations are less frequent in rural areas — do not let your tank drop below half full if you are driving west of Galway or in County Donegal.

Parking in Dublin city centre is expensive (€2 to €4 per hour) and difficult to find. Use a multi-storey car park or park outside the city and use public transport. In smaller towns and villages, parking is usually free and plentiful. Never leave valuables visible in the car, even in small towns.

Insurance, damage, and what happens if you have an accident

The rental agreement includes basic third-party liability insurance, which covers damage you cause to other vehicles, property, or people. It does not cover damage to the rental car itself. Collision damage waiver (CDW) covers damage to the rental car from accidents, typically with a €500 to €1,000 excess (the amount you pay toward repairs). Super CDW or premium coverage reduces or eliminates the excess but costs €15 to €30 per day.

Theft protection covers the car if it is stolen; this is separate from CDW and costs €5 to €10 per day. Some credit cards (particularly premium travel cards) cover rental car damage and theft automatically. Check your card's terms before you book — if you are covered, you can decline the rental company's insurance and save money. Do not assume you are covered; call your credit card issuer and ask specifically about rental cars in Ireland.

If you have an accident, stop when ready and turn on your hazard lights. Call the rental company's emergency number (it is on your rental agreement) and the Irish police (Gardaí) on 999 if anyone is injured. Take photos of all damage, the other vehicle, the scene, and the other driver's registration and insurance details. Do not admit fault or sign anything except the police report. The rental company will investigate and may charge you for repairs if they determine you were at fault and you did not purchase damage waiver coverage.

Tolls, parking, and other charges you will face

Ireland has three toll roads: the M4 Dublin to Kinnegad, the M6 Kinnegad to Galway, and the M7 Dublin to Limerick. Tolls range from €1.50 to €3.00 per journey depending on the road and vehicle type. Most rental companies charge a €5 to €10 administration fee if you use a toll road and they collect the toll on your behalf. Some companies allow you to pay tolls yourself at toll booths; ask when you collect the car.

Parking fines in Dublin are €60 to €130 if you park illegally or overstay a meter. The fine is issued to the rental company, which then charges you plus an administration fee. In Cork and Galway, parking fines are €50 to €80. Always check parking signs and pay for parking tickets before you leave the car.

Congestion charges do not exist in Ireland, but some car parks charge premium rates during peak hours. Motorway service stations charge 10 to 20 percent more for fuel than petrol stations in towns. Fill up in towns when you can.

Returning the car and avoiding unexpected charges

Return the car on time and with a full fuel tank. Late returns are charged at the daily rate, sometimes with a premium for after-hours returns. Fuel up at a petrol station 2 to 3 kilometres from the rental office so you have time to drive to the office without using fuel. If you return the car empty, the company charges you for a full tank at their inflated rate.

Before you drive away from the rental lot on pickup day, walk around the car with the staff member and document any existing damage — dents, scratches, broken lights, or interior stains. Take photos or video of the entire car, including the undercarriage if possible. The rental agreement should list all pre-existing damage; if it does not, point it out and ask them to add it. This protects you from being charged for damage you did not cause.

When you return the car, the staff will inspect it for new damage. If you have purchased damage waiver coverage, minor damage (small dents, scratches) will not be charged to you. Without coverage, you will be charged for all repairs. The company may not charge you when ready; they may send an invoice weeks later after getting repair quotes. Keep your rental agreement and all receipts until the charge appears on your credit card statement and you are certain no additional charges will follow.

Frequently Asked Questions

Do I need an International Driving Permit if my licence is in English?

If your licence is issued in English by the UK, US, Canada, Australia, or New Zealand, most rental companies will accept it without an International Driving Permit. However, some companies and police may ask for one as supporting documentation. It is inexpensive to obtain and removes any doubt; bring it if you have it.

Can I rent a car if I am under 25?

Yes, but you will pay a young driver surcharge (typically €15 to €25 per day) if you are under 25. Some budget companies require you to be 25 or older. Check the rental company's age policy when you search for cars. The surcharge is added to your daily rate and is non-negotiable.

What happens if I damage the car and I did not buy damage waiver insurance?

You are liable for all repair costs up to the value of the car. The rental company will send you an invoice after they receive repair quotes, which can take two to four weeks. If the damage is extensive, the cost can exceed €2,000. This is why damage waiver coverage or confirming your credit card covers rentals is important.

Can I drive the rental car to Northern Ireland?

Yes, but tell the rental company when you book. Most companies allow travel to Northern Ireland at no extra charge, but some require advance notice or charge a small fee. Your insurance and liability coverage extend to Northern Ireland. Do not cross the border without informing the company first, as this may void your coverage.

What if I need to return the car early or extend the rental?

Contact the rental company as soon as you know your plans. Early returns may not reduce your charge if you booked a fixed-rate deal, but some companies offer refunds for unused days. Extensions depend on availability; during peak season, the car may be booked by another customer and you cannot extend. Extending usually costs more per day than your original rate.
