Renting a Car in Ireland: Insurance, Excess and the Credit Card Trap

Unlike in the United States, an Irish rental includes third-party liability and collision damage waiver (CDW) as standard. The catch is elsewhere: the remaining excess is among the highest in Europe, frequently between €1,500 and €3,000 depending on vehicle category — and it applies to the slightest scrape. On country roads a car and a half wide, lined with stone walls and hedges, this is no theoretical risk: side scratches and torn-off mirrors are the most routine claim in the country.

To bring that excess down to zero, three routes: the rental company's Super CDW (often €15 to €30 per day, the most expensive but simplest option), an excess insurance policy bought online from a third-party insurer (a few euros per day, reimbursement after the fact), or your premium credit card's insurance — with, in Ireland, a specific complication detailed below.

Ireland is famous among travellers for a practice you meet almost nowhere else in Europe: if you plan to decline the Super CDW and rely on your card's insurance, most agencies demand a written letter from the card issuer confirming that the cover applies in Ireland. Without this document — recent, in English, explicitly mentioning Ireland — the agency will impose its own cover or block a much larger deposit on the card.

The explanation lies in the local market's history: Ireland has long featured, along with a few other destinations, on the exclusion list of many North American credit cards, and Irish rental companies have generalised the proof requirement to all customers. Before departure, ask your bank for a personal letter of cover mentioning Ireland, or check the conditions in our dedicated article on credit card rental insurance. If your bank drags its feet, third-party excess insurance bought online remains the cheapest fallback.

Second local peculiarity: even with 'zero excess' Super CDW, many Irish contracts specifically exclude the parts most exposed on the country's roads — mirrors, tyres, wheels, windscreen and glass, roof and underbody. Some companies sell an extra option for these items, others include them in their top-tier packages: the only way to know is to read the coverage grid line by line before signing.

The complementary reflex is worth gold in Ireland more than anywhere: a full photographic walk-around at pick-up — all four sides, both mirrors, the wheels, the windscreen — repeated at drop-off in front of an agent if possible. Disputes over side scratches discovered after return are the leading cause of contested deposit charges.

Here are the four possible strategies, from simplest to cheapest.

Driving on the left is quickly learned — we devote a full guide to it — but it weighs on two booking choices. First the gearbox: the Irish fleet is mostly manual, and shifting with your left hand adds difficulty at the start; an automatic, pricier and quickly sold out in high season, genuinely simplifies the first days. Then the size: on the roads of Connemara or the Dingle Peninsula, every centimetre of width counts — the SUV that looks reassuring on paper becomes a handicap between two stone walls.

Caution is not just a matter of comfort: research on tourist accidents, such as the analysis by Stephen Page and Denise Meyer published in 1996 in Annals of Tourism Research, shows that road accidents rank among the leading causes of injury for international visitors, particularly in countries that drive on the opposite side to their habits (study on Google Scholar: scholar.google.com/scholar?q=Page+Meyer+tourist+accidents+an+exploratory+analysis). The first kilometres out of Dublin airport, tired from the flight, concentrate the risk: plan a simple leg for day one.

If your route crosses into Northern Ireland — Giant's Causeway, Belfast — flag it at booking: the border itself is open, but most Republic-based rental companies require a cover extension (a few euros per day) for the insurance to remain valid in the United Kingdom. Driving north without declaring it can void your cover in the event of a claim.

As for conditions: the minimum age is generally 21 or 23 depending on the brand, with a young driver surcharge up to 24 or 25, and some agencies also apply an upper age limit beyond 75 — an Irish peculiarity worth checking if it concerns you. The deposit is blocked on a credit card in the main driver's name; expect roughly the amount of your chosen excess.
