Renting a Car in Ireland: What Tourists Need to Know (2026)

Where to book — comparison sites vs direct

Comparison / aggregator sites

• DiscoverCars, Rentalcars.com, AutoEurope, Kayak, Momondo — compare prices across multiple suppliers in one place
• Price-match capability — the same car often appears at different prices via different aggregators, so comparing is genuinely worth 15–30 minutes
• Flexible cancellation — most aggregators offer free cancellation up to 48 hours before pickup; worth paying a small premium for
• Watch for hidden exclusions — some "too cheap" rates don't include CDW; Super CDW pitches on pickup are the industry's margin leader

Direct from major rental companies

• Hertz, Enterprise, Europcar, Budget, Avis, Sixt — international chains with large Irish presences
• Dan Dooley, Irish Car Rentals, Easirent — Irish-focused suppliers, sometimes cheaper for longer rentals
• Direct booking sometimes offers better loyalty rewards, free upgrades, and simpler modifications than going through an aggregator

Airport vs city pickup

Dublin, Cork, Shannon, Knock and Kerry airports all have on-site rental desks. Airport pickups are the most convenient but attract airport location surcharges of 15–25% on top of the base rate. If you're arriving late and staying in Dublin the first night, picking up the car the morning after from a city-centre depot can be meaningfully cheaper.

How much car rental actually costs in Ireland (2026)

Weekly rates are generally 10–25% cheaper than the daily equivalent × 7. A 7-day rental often costs roughly what 5 days would cost daily. For trips longer than 4 days, always price-check the weekly rate.

Location matters — Dublin rentals are typically the most expensive; Shannon, Cork and Knock airports are often 20–30% cheaper for the equivalent car. If your itinerary is flexible, flying into Shannon or Cork can be a meaningful saving.

Book early — booking 7+ days ahead is typically around 14% cheaper than last-minute. For summer peak, book 2–3 months ahead to guarantee automatic availability.

Age restrictions — who can rent in Ireland

Young-driver specifics: Hertz typically accepts drivers aged 23/24+ on smaller car groups with a €26/day young-driver surcharge. Europcar allows under-25 drivers with a surcharge. Enterprise and National have similar policies. Under-21 is effectively impossible at most major chains.

Older drivers: some companies apply a maximum-age restriction of 70, 75 or 80, while others (including Europcar in the Republic of Ireland) have no upper limit at all. If you're 70+ and travelling to Ireland, always check the specific supplier's policy before booking — it varies significantly, and policies are occasionally tightened.

Licence requirements

• A valid full driving licence — provisional / learner permits are not accepted for car rental
• Must have held the licence for 1–2 years minimum (varies by company)
• Bring the physical licence — photos and photocopies are not accepted, and a Garda stop requires the original
• UK, US, Canadian, Australian, NZ licences accepted on their own — no IDP needed
• International Driving Permit only recommended if your national licence is in non-Latin script (Chinese, Arabic, Japanese, Korean, Greek, Cyrillic etc.)
• EU/EEA licences fully accepted under mutual recognition

Insurance explained — the most important section

Irish rental insurance is where margin is made, where holidays go sideways, and where tourists sign up for policies they don't need (or miss the one they do). Here's the plain-English breakdown.

1. Third-party liability — always included

Mandatory under Irish law, always bundled with any rental. Covers damage you cause to other vehicles, people or property. No action needed from you.

2. Collision Damage Waiver (CDW)

Reduces your liability for damage to the rental car itself — but to a ceiling, not to zero. You remain liable up to the excess amount:

• Economy / compact: €1,500–€1,800 excess typical
• Mid-size / SUV: €2,000–€2,500 excess typical
• Premium / luxury: €2,500–€4,000+ excess typical

If the car is damaged by any amount up to the excess ceiling, you pay the full repair cost. Above the excess, CDW covers it.

3. Super CDW (Excess Reduction)

Reduces the excess to €0–€100 in exchange for an additional €15–€30/day. On a one-week rental that's €105–€210 on top. For peace of mind on Irish rural roads — where kerbed alloys, scraped panels and cracked windscreens are all annoyingly common — Super CDW is almost always worth it.

4. What CDW usually doesn't cover

5. Personal Accident Insurance (PAI)

Covers medical costs and injury compensation for you and passengers. Usually unnecessary if you already have travel or health insurance with accident cover. Skip unless your existing cover specifically excludes Ireland or rental cars.

6. Credit-card rental insurance — the alternative

Many US premium credit cards (Chase Sapphire, Amex Platinum, Capital One Venture X) include secondary CDW for rentals paid fully on the card. To use it:

1. Pay the full rental on the credit card at pickup
2. Decline the rental company's CDW
3. Accept the card-hold the rental company places on your card (typically €1,500–€3,000)
4. In the event of damage, pay the rental company then claim from the card's insurance

Caveat: check your specific card's Ireland coverage — some cards explicitly exclude Ireland and Northern Ireland. Read the benefits guide, not just the marketing page.

Automatic vs manual — the Irish-specific advice

Ireland has more manual ('stick shift') cars on the road than most US drivers expect. Rental fleets reflect this — manuals are still common, and automatics are often in limited supply, especially in summer peak.

Pick automatic if…

• You've never driven a manual before
• You'll be doing urban driving (Dublin, Cork, Galway)
• You're not confident with the left-hand gear stick while navigating on the left
• Multiple drivers will share the car and at least one isn't comfortable with manual

Pick manual if…

• You're a confident manual driver and don't mind the adjustment
• Budget is a key concern (saves €10–€20/day)
• You prefer the control on steep mountain routes (the West, Donegal)

Fuel policy — almost always full-to-full

• Pick the car up with a full tank, return it full — the universal Irish rental norm
• Refuel 5–10 km before the return airport — airport-adjacent service stations are significantly cheaper than the forecourts just outside the rental return
• Keep the final fuel receipt — evidence if the rental company claims the tank wasn't full
• Avoid 'refuel on return' option — rental companies charge around 50–100% more per litre than forecourt prices
• Make sure you put the right fuel in — Irish pumps are colour-coded (black = diesel, green = petrol), but the nozzle sizes can be similar. Mis-fuelling is not covered by insurance and repairs start at €500+

For current Irish fuel prices, see our driving in Ireland guide. As of April 2026, petrol averages €1.91/L, diesel €2.14/L.

Tolls and the M50 trap

Your M50 options in a rental

1. Buy the rental company's daily toll pass — typically €10–€15/day (Hertz, Europcar). Covers all Irish tolls. Worth it if you'll be around Dublin more than a day or two.
2. Set up a free eFlow video account against the rental plate at eflow.ie. Pay €3.20 per crossing, no admin fee. Takes 5 minutes to set up at rental pickup.
3. Pay as you go at eflow.ie or Payzone retailer before 8pm next day. €3.80 per crossing. Easy to forget, easy to miss.
4. Avoid the M50 — not always possible in Dublin, but feasible for some itineraries.

All other Irish tolls (M1, M3, M4, M7/M8, N6, N8, N25, Dublin Port Tunnel, Limerick Tunnel, East Link) have physical toll plazas — just pay cash or card at the gantry. Full detail in our toll roads Ireland guide.

Cross-border travel — Northern Ireland and beyond

Northern Ireland (Derry, Belfast, Giant's Causeway)

Most Republic of Ireland rental cars can be driven into Northern Ireland — check the specific supplier's policy:

Always declare Northern Ireland travel at pickup so the fee and insurance are recorded. Simply driving across without declaring can void your insurance and expose you to fines.

UK mainland (Scotland, England, Wales)

Much more restricted. Some Irish rental suppliers don't permit mainland UK travel at all. Those that do typically charge €170–€200+, sometimes require separate breakdown cover, and may require additional insurance. For multi-country itineraries spanning Ireland + GB, it's often cheaper to return the Irish rental and pick up a fresh one in Great Britain.

Ferries to the UK

If you plan to take the rental on a ferry (Dublin–Holyhead, Rosslare–Pembroke, etc.), check both the rental company's policy and the ferry operator's requirements. Most rentals permit ferry use within Ireland and NI; few permit ferry transport to Great Britain without a UK-travel agreement.

Pick-up checklist — protect yourself at the counter

Damage disputes are the single most common tourist complaint about Irish rentals. Spending 10 minutes at pickup to photograph everything and get everything in writing is the single most effective protection against unexpected charges at return.

One-way rentals

Picking up in one city and dropping off in another saves you a backtrack drive but adds a fee:

• Within Ireland (Dublin → Shannon, Cork → Dublin, etc.): typically €50–€150 extra depending on distance and supplier
• Ireland → Northern Ireland (Dublin → Belfast): €50–€150 one-way fee plus the NI cross-border fee
• Ireland → UK mainland (Dublin → London): international one-way fee plus UK-travel fee — typically €200–€400+, and not all companies permit it
• Sometimes free — Enterprise and others occasionally promote free one-way drop-offs within Ireland, especially off-peak. Always ask.

For shorter itineraries, the backtrack drive is often cheaper than the one-way fee. For longer round trips (e.g. Dublin → Killarney → back), it's a wash.

Sat nav and navigation

• Built-in sat nav: €5–€15/day. Usually worth skipping — your phone is better.
• Bring a phone mount (suction or vent) for €10 from any airport shop
• Google Maps / Waze / Apple Maps all work well in Ireland
• Download offline maps for your whole itinerary — mobile coverage is patchy in rural western Ireland (Kerry, Connemara, Donegal)
• Watch out for very narrow routes — Google Maps occasionally proposes grass-covered boreens that shouldn't be driven by a rental car. See our driving in Ireland guide for the rural-road etiquette
• CarPlay / Android Auto — increasingly available in rental cars, but not guaranteed; bring your USB-C / Lightning cable

Returning the car — avoiding surprise charges

1. Refuel within 5–10 km of drop-off with a full tank. Keep the receipt.
2. Photograph the return condition — full exterior, fuel gauge, odometer, interior. Timestamped, ideally before you hand the keys over.
3. Get a written return acknowledgement from the staff member on duty — confirming mileage, fuel level, and that no damage was noted
4. If damage is flagged that you dispute, refuse to sign anything that says you accept liability. Show your pickup photos. If unresolved, email the rental company's customer service immediately with photos attached.
5. Empty the car completely — rental companies charge "cleaning" fees for trash, food spills, sand/mud beyond normal wear
6. Keep the contract and photos for at least 90 days — disputed charges sometimes appear weeks after return
