Car Rental Insurance in Ireland: What Coverage Do You Actually Need?

The first time I watched a cousin from Boston sign a rental agreement at Dublin Airport, he paused at the insurance section, looked up at me, and said: "Malachy, I have no idea what any of this means."

He was staring at acronyms — CDW, Super CDW, TP, PA, Excess — and a number that made him flinch: €2,500. That figure, printed beside the word "excess," is the amount the rental company would hold on his credit card if he skipped their additional cover. It is also the moment most North American travellers realise that car rental insurance in Ireland works differently than at home.

This article is what I told him that morning.

What the Rental Desk Is Actually Selling You

When you stand at a rental counter in Ireland, the conversation begins with CDW — Collision Damage Waiver. This is not insurance in the traditional sense. It is a waiver that limits how much you can be charged for damage to the rental car. The catch is the excess, also called the deductible: the amount you remain liable for before the waiver kicks in.

At most Irish rental desks, that excess sits between €1,500 and €3,000. The desk then offers you Super CDW, also called Excess Waiver, which lowers or removes that liability for an additional daily charge — typically €15 to €30 per day. Theft Protection (TP) covers the vehicle if stolen. Personal Accident insurance (PA) covers medical costs. Windscreen and tyre cover may be offered separately.

Here is the part that catches North Americans off guard: the rental company places a hold on your credit card for the full excess amount. That €2,500 is not theoretical. It reduces your available credit for the duration of your trip. If you do not have sufficient available credit, you may be refused the car entirely.

This is the system at most rental counters. It is standard, and it catches people every single day.

Why Your Credit Card Insurance May Not Work Here

Many North Americans arrive believing their credit card's rental car coverage will protect them. In most cases, it will not.

Credit card insurance is secondary coverage. You must first pay the rental company for any damage, then submit a claim to your credit card provider for reimbursement. The rental company still places the full excess hold on your card at pick-up. If damage occurs, you pay upfront, then spend weeks navigating paperwork. The rental company has no obligation to help you. Their obligation is to their own insurer, not to your credit card provider.

Third-party excess insurance, purchased online before travel, suffers from the same problem. It is reimbursement-based. The rental desk still places the hold on your card. You still face the paperwork.

My Irish Cousin does not accept credit card or third-party insurance. The reason is simple: the hold on your card remains regardless of what external policy you believe you have. The gap is not in the policy language — it is in the moment at the rental desk when your card is charged.

What Zero Excess Actually Means on the Ground

When a rental company advertises "zero excess," the details matter. There are two ways to interpret that phrase, and only one protects you fully.

The first is the reduced excess offered by Super CDW at the rental desk. You still pay a daily fee. There may still be exclusions — undercarriage, roof, tyres, windscreen, or wheels may remain uncovered. You may still face a reduced hold on your card. Read the fine print.

The second is genuine zero excess, zero deductible coverage built into the rental rate itself. No hold on your credit card. No amount you remain liable for. If the car is damaged, you are not charged. If the windscreen cracks, you are not charged. If the tyre needs replacing, you are not charged.

This is the coverage My Irish Cousin includes as standard. No daily add-on. No hold on your card. When you sign the proposal and pay, the price is the price — insurance included, excess eliminated.

With a standard rental, you hand over a credit card that suddenly has €2,500 less available credit. You spend your holiday aware that a scraped wing mirror could cost you hundreds. You return the car and wait while an employee inspects every panel for damage you may not have caused.

With zero excess built into the rate, you pick up the keys and drive. That is the entire transaction.

What Is Covered — and What Is Not

Even with comprehensive rental insurance, there are limits. Understanding them before you drive prevents nasty surprises.

My Irish Cousin's insurance covers damage to the rental vehicle, damage to third parties including other vehicles and property, full roadside assistance, and glass or tyre repair or replacement including call-out charges. Driving in Northern Ireland is covered. Wing mirrors, scratches, dents, and bumps are included. Zero excess, zero deductible.

However, three areas of driver negligence are excluded from every rental policy in Ireland, including ours:

Lost keys. Replacement cost is debited to your card. Keep them on the same ring as your hotel key, in the same pocket every time.

Wrong fuel. Putting petrol into a diesel car — or vice versa — happens more often than you would think when the driver is used to different conventions at home. The cost of draining the tank and repairing damage is yours. If you misfuel, do not start the engine and do not contact roadside assistance first. Ring My Irish Cousin immediately.

Burnt clutch on a manual car. Riding the clutch on Ireland's hills and narrow roads can burn it out. Repair can reach €2,500. If you are not fully comfortable driving manual on the left, on narrow roads, with roundabouts — book automatic. The extra cost is far less than a clutch replacement.

These exclusions exist not to trap you, but to define the boundary between normal driving risk and avoidable driver error.

The Replacement Car Question Nobody Asks

There is one insurance question almost nobody asks until it is too late: what happens if the car is damaged badly enough that it cannot be driven?

With most rental companies in Ireland, the answer is grim. If the car is no longer drivable, your rental agreement is voided. The company has no obligation to provide a replacement. You are left without transport, in a foreign country, with luggage and bookings and no way to reach them.

Unless there is gross negligence — driving under the influence, for example — My Irish Cousin will provide you with a replacement car. This is not an add-on. It is part of the package, because the point of renting a car is to have transport for your trip, and a damaged car does not change that requirement.

This is the difference between a rental company and a booking engine. A broker processes your reservation and takes their commission. They are not available when your car is damaged on a Sunday afternoon in County Kerry. We are.

What Coverage Do You Actually Need? A Direct Answer

If you are renting a car in Ireland as a North American visitor, here is the coverage you actually need, stripped of marketing language:

You need collision and damage cover with zero excess, meaning no hold on your card and no amount you remain liable for. You need theft protection included. You need third-party cover for damage to other vehicles or property. You need windscreen and tyre cover that does not require you to pay first and claim back later. You need roadside assistance that answers the phone when you are on a narrow R-road in County Mayo and something has gone wrong.

You do not need a separate policy that reimburses you after the fact. You do not need to pay a daily fee at the rental desk to reduce an excess that should not exist in the first place. You do not need to spend your holiday with a €2,500 hold sitting on your credit card.

If your rental quote does not include all of the above in the base rate, the quote is incomplete.

The driving is the point of the trip. The car is not an afterthought. It is the mechanism by which you experience the country. Insurance that leaves you exposed defeats the purpose.

For visitors who want the route planned and the accommodation booked without the weeks of research, Celtic Vacations build self-drive packages where the driving remains yours but the logistics are handled. The accommodation is pre-booked at each stop. The route is mapped. You still need a car — but you do not need a spreadsheet.

If you are ready to sort the car, request a quote from My Irish Cousin. The insurance is included. There is no deposit. There is no hold on your card. You sign, you pay, you drive. That is how it should work.

Frequently Asked Questions

Is car rental insurance mandatory in Ireland?

Yes. By law, every rental vehicle must carry at least third-party insurance. What is not mandatory is the level of cover beyond that. You can legally rent with a high excess and no additional protection — but you will be personally liable for damage up to that amount.

Does my US car insurance cover me in Ireland?

No. Your American auto insurance does not extend to rental vehicles in Ireland. Your credit card may offer secondary coverage, but it requires you to pay first and claim back later, and the rental desk will still place a hold on your card for the full excess.

What is the difference between CDW and Super CDW?

CDW limits your liability for damage to the rental car but leaves an excess — typically €1,500 to €3,000 — that you must pay before cover applies. Super CDW reduces or removes that excess for an additional daily charge, purchased at the rental desk.

Can I use a third-party excess insurance policy instead?

You can purchase one, but the rental company will still place the full excess hold on your credit card at pick-up. Third-party policies are reimbursement-based. My Irish Cousin does not accept third-party insurance as a substitute for included cover.

What happens if I have an accident in a rental car?

With most rental companies, you pay the excess, the agreement may be voided if the car is undrivable, and you are left without transport. With My Irish Cousin, unless there is gross negligence, we provide a replacement car and the insurance covers the damage with no excess charged to you.

Is Northern Ireland covered by Irish rental insurance?

With My Irish Cousin, driving in Northern Ireland is covered as standard. Travel to Scotland, England, or Wales requires advance agreement and additional cover. Taking a rental car to France or Spain is not permitted.

Does the rental company check my driving record?

My Irish Cousin does not ask for your driving record or licence details upfront. We ask one question: is the driver 25 or older? You must present a valid driving licence in English at pick-up.
