Car hire excess insurance, explained
When you collect the car, they'll offer to "waive your excess" for €15–25 a day. A standalone excess policy does the same job for a fraction of the price — and covers the tyres, glass and underbody the desk quietly leaves out.
Why the gap is so big
The rental company's waiver is priced per day and sold under time pressure. A standalone policy is the same idea — it reimburses the excess if the car's damaged or stolen — bought ahead, at insurance prices, and it usually covers the bits the desk excludes.
The counter "excess waiver" / "super cover", added when you're tired and keen to get going.
A single-trip policy bought before you travel — often a fifth of the desk price.
Rent more than a couple of times a year? One annual policy covers every trip.
What actually differs
| Decline everything | Rental-desk waiver | Standalone excess policy | |
|---|---|---|---|
| Typical cost (2 weeks) | €0 — but you carry the full excess | ~€200–350 | ~€45, or ~£79 a year |
| Covers the excess if damaged/stolen | No | Yes | Yes (reimbursed) |
| Tyres, glass, underbody, roof | No | Often excluded | Usually included |
| Bought under pressure at the desk | — | Yes | No — sorted before you travel |
| Rental company can refuse it | — | It's theirs | No — it's independent, they needn't approve it |
Compare standalone car-hire excess cover: per-trip for one holiday, or an annual policy if you rent more than twice a year. Most residencies covered, including the EU.
Common questions
No. You can decline all cover and carry the excess yourself, buy the rental desk's waiver, or buy a standalone policy. It's optional — which is exactly why the desk can't refuse a standalone policy: they don't need to see or approve it.
The amount you're liable for if the car is damaged or stolen — often €800–€2,500, blocked on your card at pickup. Excess insurance reimburses you for that if you have to pay it.
Usually yes — tyres, glass, underbody and roof are commonly included, and these are exactly the parts the rental desk's own waiver often excludes. Always check the specific policy wording.
One holiday a year → a single-trip policy is cheapest. Two or more rentals a year → an annual policy almost always wins, covering every trip for one flat price.
If you're charged for damage, you pay the rental company, then claim the amount back from your excess insurer with the paperwork. You're not arguing with the rental desk about cover — you settle, then get reimbursed.
