A low daily rate does not tell you the full cost, how much money may be held on your card, or whether your contract permits the route you plan to drive. Before you book, compare the complete offer: total price, cover and excess, deposit, fuel, mileage and the terms for every country on your itinerary.
These ten checks are ordered by potential financial impact, the risk that you cannot collect the vehicle or complete your planned trip, and how difficult a problem is to fix after booking. This is a ranking of checks, not rental companies. Fees and contracts vary by provider, country, location and booking channel.
1. Calculate the total price, not just the daily rate
Compare offers with the same pickup and return times and locations, a similar vehicle group, included mileage and fuel terms. Check the total for the full rental and identify which charges are required and which extras are optional.
Possible extras include an airport-location charge, a one-way return fee, a young-driver surcharge, an additional driver, a child seat, out-of-hours delivery and extra cover. None applies in every booking. Look for the amount in the price breakdown before you enter a card or pay.
Why it ranks first: the total is easy to compare before payment, while overlooked terms can be harder to change after a reservation is made.
2. Find out what the insurance covers and what you could still owe
In the EU, a rental vehicle must have third-party liability insurance included in the rental price. That does not automatically cover damage to the rental vehicle itself, theft, personal belongings or injury to the driver.
Check the excess, exclusions and claims procedure. Look specifically for how the contract treats glass, tyres, the roof, underbody, keys, the wrong fuel type or driving outside an authorised territory. Do not assume a product described as “full cover” removes every liability.
If you book through an intermediary, compare its excess-refund product with the cover offered by the rental company. Ask who charges you first, how you submit a claim and which documents are required.
Why it ranks second: if the car is damaged or stolen, the difference between cover, excess and an exclusion can be far larger than the daily-rate difference.
3. Check the deposit and exact card requirements
Ask how much will be charged or pre-authorised as a guarantee, when it will be released and what could delay release. Confirm which card type is accepted, whether it must be physical and whether the cardholder must be the main driver. These are provider-specific terms, not universal rules.
Check that your available card limit will cover the deposit as well as your other travel spending. If the booking intermediary accepts one payment method but the rental desk requires another for the deposit, find that out before booking.
Why it ranks third: an unsuitable card or insufficient limit can prevent pickup even when the reservation has been paid.
4. Confirm in writing where you may drive
If you will cross a border, take a ferry or return the vehicle in another country, tell the rental company when you book. Check that the route is permitted, whether a fee applies, and whether cover, vehicle documents and breakdown assistance apply in every country on the itinerary.
Do not assume that permission to rent a car in one country automatically lets you drive it everywhere. For destinations outside the EU, Norway and Iceland, check the relevant local rules too.
Why it ranks fourth: a border or ferry restriction can change the entire itinerary and affect insurance and roadside assistance.
5. Read the cancellation, delay and no-show terms
Check when you can cancel or change the booking and what, if anything, will be refunded. Car hire in the EU does not automatically receive the general 14-day cooling-off right for distance purchases. The rental company’s terms may still allow cancellation.
If you arrive by air, find out how to report a delay and whether the desk will hold the car after the stated pickup time. Compare the intermediary’s no-show policy with the policy of the company actually supplying the vehicle.
Why it ranks fifth: flight, car and intermediary bookings can have different change and refund rules.
6. Identify the actual rental provider and any intermediary
Before paying, find the legal name of the company from which you will collect the car and read its contract. If you book through a broker or platform, keep those terms and the voucher too. The intermediary may take the reservation while a different company provides the vehicle at pickup.
Check whom to contact about a flight change, a deposit dispute or a vehicle problem. The name on an advert or booking page is not always the party to the rental contract.
Why it ranks sixth: if there is a dispute, you need to know which company handles each part of the booking and where to send a written query.
7. Compare the fuel policy and included mileage
Read what fuel level is required at return, how refuelling charges are calculated and whether the provider adds a service fee. If you prepay for fuel, check whether unused fuel is refunded; do not assume it will be.
Confirm whether mileage is limited and what excess distance costs. For a long journey, the difference between included and chargeable mileage can materially change the total price.
Why it ranks seventh: fuel and mileage depend on your route and can turn an apparently cheap offer into a more expensive one.
8. Check who is allowed to drive
Make sure your driving licence is valid in the countries you will visit. Check the minimum age, how long you must have held a licence, any young-driver fee and whether every additional driver must be named in the contract.
Do not plan to let another traveller drive just because they are in your group. Age, experience and accepted documents vary; confirm them for the specific vehicle and country.
Why it ranks eighth: if the main or additional driver does not meet the conditions, the car may not be released or the agreed cover may not apply.
9. Verify pickup and return times
Check the local time and address, office hours, instructions for flight delays and whether there is a grace period. For return, find out how the company charges for lateness, an out-of-hours drop-off or an extra day. There is no universal grace period.
Allow time for inspection and refuelling if the contract requires it. For an after-hours return, ask where to leave the key and when the vehicle will be checked.
Why it ranks ninth: timing can add a charge or leave the return without a staff member to confirm the car’s condition.
10. Plan the inspection and evidence before you leave
At pickup, inspect the vehicle and compare scratches, glass, tyres, interior, fuel level and odometer with the handover form. Ask for every visible mark to be recorded before you drive away. Take clear photos and a short video.
At return, inspect it again and ask for a signed receipt showing whether there are any remarks. If you drop it off after hours, photograph it in the designated return area and keep proof of the time. After a breakdown or accident, follow the contract’s emergency procedure and notify the company; do not arrange repairs without authorisation.
Why it ranks tenth: the inspection is your last opportunity to document the vehicle’s condition and reduce the risk of a later damage dispute.
Quick check before payment
Keep written confirmation of the total price, excess and exclusions, deposit and card, border rules, cancellation, fuel and mileage. If one answer is unclear, ask the company named in the contract before paying.
There is no single contract for every company and country. EU information sets out general consumer rules; the confirmed booking and rental agreement determine the terms for your vehicle. Checked on 27 September 2026.
