Never buy excess insurance at the rental desk
The desk agent isn’t lying. Your excess really is €1,500. If you scrape the car against a bollard in a Seville car park, that is genuinely what you owe.
What they don’t say is that the same risk is insurable for about a tenth of the price if you buy it anywhere other than the counter you are currently standing at.
What is actually in your rental price
Almost every hire in Europe already includes two things by law or by convention: third-party liability, and a Collision Damage Waiver with theft protection.
CDW is not insurance. It is a waiver — a promise by the rental company not to pursue you for the full value of the car. But the waiver has a hole in it, and the hole is the excess: the first €800 to €2,500 of damage, which stays yours.
So the excess is real, and the question is only who insures it.
What the desk is selling
The upsell has several names — Super CDW, excess waiver, excess reduction, Premium Protection, Zero Excess. They all do the same thing: buy the hole out of the waiver, usually down to zero or to a few hundred euros.
Across Europe in mid-2026 that costs roughly €15–35 per day. Mediterranean resort airports in August push past €40 for anything bigger than a supermini. On a ten-day family hire that is €200–400, frequently more than the car itself.
Two further things about the desk product are worth knowing before you decide.
It usually still excludes the parts most likely to break. Tyres, glass, wheels, undercarriage, roof and mirrors are the classic carve-outs, and they are exactly what a hedge-lined Irish boreen or a Corsican mountain road takes off a car. Read the counter product’s exclusions, not its headline.
And it is scripted. The agent is not improvising, and in many networks they are on a sales target. The pause after “and what will you do if something happens to the car?” is a technique, not a question. It is fine to answer it in four words.
What to buy instead
A standalone excess reimbursement policy, bought before you travel, from an insurer rather than a rental company.
Annual Europe-wide cover from the UK and Irish specialists started around £42–47 (roughly €50–55) in mid-2026, with better-limit policies into the €70s. Single-trip cover is about €5–15 per day, which is still a third of the counter price. Worldwide cover costs more; if all your driving is in Europe, don’t buy it.
Standalone policies typically include tyres, glass, wheels and undercarriage — the things the desk product excludes. That is the real argument, more than the price.
Compare on four things, in this order:
- Single-claim limit. It must exceed the largest excess you’ll face. €4,000–5,000 is a common and adequate limit for Europe.
- What is included. Tyres, glass, undercarriage, roof, mirrors, lost keys, misfuelling, towing, and the rental company’s “loss of use” and admin fees.
- Vehicle and hire limits. Most policies cap the hire at 31 or 62 consecutive days, and exclude vans, motorhomes, and cars above a value or age threshold.
- Excess on the excess policy itself. Some have one. It should be zero.
How the money actually flows
This is the part that trips people up, and it is why the desk upsell keeps working.
A standalone policy is reimbursement. If you damage the car, the rental company charges your card for the excess. You then claim it back from your insurer, with the rental agreement, the damage report and the charge receipt, and you are paid out in a few weeks.
You are out of pocket in the meantime. That is the trade you are making for saving €250 on a fortnight’s hire. For most people it is obviously the right trade. For someone travelling on a debit card with €400 of headroom, it is not.
Keep the paperwork. Photograph the signed damage sheet at pickup and at drop-off, and photograph the car itself — all four corners, roof, windscreen, wheels, and the fuel gauge — with the timestamp on. Claims fail on evidence, not on wording.
Ireland is the exception
Irish hire behaves differently enough that the standard advice needs an amendment.
CDW and theft protection are normally bundled into the headline rate, which looks generous. But the excess behind it sits at roughly €1,500–€3,000, and — this is the part that matters — the deposit hold on your card runs €1,500 to €5,000, well above the mainland norm.
A standalone excess policy does nothing about that hold. It reimburses you after a claim; it does not stop Hertz blocking €3,000 on your card for a fortnight. If that hold would consume your credit limit, or if you are on a debit card, you have a real problem that no amount of being right about insurance solves.
Two workable answers. Either take a credit card with genuine headroom and buy the standalone policy as normal, or accept the desk waiver specifically in Ireland because it collapses the hold to €100–500 — and price that into the booking rather than discovering it at the counter.
There is a second Irish wrinkle. Card-provided hire car cover — the CDW benefit on premium credit cards — very commonly carves out the Republic of Ireland by name. If your plan was to rely on your card, check the policy wording for Ireland specifically before you land, not after.
The same caution applies, for different reasons, to Iceland (gravel and sand damage are usually excluded everywhere) and to hires collected in Italy, where some regional operators make third-party liability top-up effectively compulsory.
What to say at the desk
Have the policy document on your phone. Then:
“No thank you, I have my own excess cover.”
That is the whole script. You do not need to name the insurer, justify the decision, or debate the exclusions. If pressed, “I’m happy with the standard excess” ends it.
Expect one or two more attempts — the second is often framed as a warning about the deposit hold, which is the one honest thing in the pitch. Confirm the hold amount before you sign, so it isn’t a surprise.
Do not, under any circumstances, sign a rental agreement you haven’t read the excess figure on. It is on the front page, and it is the only number that matters.
When the desk product is genuinely the right call
Rarely, but not never.
If the hire is under three days, the daily gap narrows and the admin may not be worth it. If you are in Ireland with a tight card limit, see above. If you are hiring a category the standalone policies exclude — a nine-seater, a campervan, anything over about €50,000 in value — your policy may not cover you at all, and buying at the desk is the only cover available.
Check that before you travel. Discovering it at the counter is how people end up buying the €35-a-day product anyway, at the worst possible moment.
How we make money on this
The advice above is to buy the €55 policy instead of the €350 one, which earns us considerably less — we’d publish it either way, and the excess-cover market having an affiliate programme is a coincidence rather than a reason.
