Compare Car Hire Offers Worldwide

Search car hire offers for your destination and travel dates, then compare more than the headline rental price. A useful review should include the total price, fuel policy, mileage allowance, driver age requirements, security deposit, insurance excess and cancellation conditions.

Two car hire offers with a similar price can have very different rental conditions. One may include unlimited mileage and a full-to-full fuel policy, while another may have mileage limits, a larger deposit or additional charges for younger or older drivers. Comparing these details before booking can help you choose the offer that best suits your trip.

How to compare car hire offers

Enter your trip details

Search using your preferred collection location, dates, times and driver age. If you plan to return the car somewhere else, include the different return location in your search.

Compare the complete offers

Compare the total price, together with the fuel policy, mileage allowance, driver age requirements and surcharges, security deposit, insurance excess, accepted payment cards, cancellation terms.

Check everything before booking

Before confirming, recheck that you meet all of the selected provider's rental conditions. If mandatory conditions are not met, the rental provider may refuse to release the vehicle at pick-up.

Compare more than the headline car hire price

The displayed rental price is only one part of an offer. Before deciding which car to book, compare the main conditions that can affect suitability, the amount needed at collection and the overall cost of your rental.

Price & payment Total rental price, amount payable now and amount due at collection.
Fuel & mileage Fuel return conditions, mileage allowance and excess-distance charges.
Driver requirements Minimum age, maximum age, age-related surcharges and licence conditions.
Deposit & excess Security deposit, accepted payment cards and insurance excess.

What should you compare in a car hire offer?

The lowest displayed price does not necessarily mean the lowest overall cost or the most suitable rental. Compare the important parts of each offer before making your choice.

The main details to compare between car hire offers
Compare Why it matters What to look for
Total rental price The headline daily rate does not always tell you the full cost of the rental. Check the total price for your dates, what is included and whether anything remains payable at collection.
Fuel policy Different fuel arrangements can affect the real cost of the rental. Look for the fuel level at collection and return, whether the policy is full-to-full and whether refuelling or service charges can apply.
Mileage allowance Limited mileage can make an apparently cheaper offer more expensive on a long journey. Check whether mileage is unlimited or restricted and the charge for exceeding any allowance.
Driver age requirements The driver's age can affect both eligibility and the final rental price. Check the minimum and maximum driver age and whether a young-driver, senior-driver or other age-related surcharge applies.
Security deposit The deposit may be considerably higher than the amount paid for the rental itself. Check the deposit amount, which payment cards are accepted and whether the card must be in the main driver's name.
Insurance excess The excess can determine how much you may be responsible for if the vehicle is damaged or stolen. Check the excess amount, the cover included with the rental and any exclusions.
Cancellation conditions Free cancellation periods and refund rules vary between offers. Check the exact cancellation deadline, amendment rules and whether any part of the booking is non-refundable.
Collection location An airport terminal desk, shuttle location and city branch can provide very different collection experiences. Check whether collection is in-terminal, at a rental centre, off-airport by shuttle or at another location.
Payment card requirements Some providers require a particular type of card before releasing the vehicle. Check whether credit or debit cards are accepted, whether the card must be in the main driver's name and whether sufficient funds or credit are available for the deposit.
Driving licence requirements Rental providers can have specific licence requirements, including how long the licence must have been held. Check the accepted licence type, minimum licence-holding period and whether any additional driving permit or documentation is required.
Identification requirements The rental provider may require identification in addition to the driver's licence. Check which identification documents must be presented at the rental desk.
Additional drivers and extras Optional items can increase the final price. Compare charges for additional drivers, child seats and any other extras required for your trip.
One-way or cross-border travel Taking the car to another country or returning it elsewhere may require permission or an additional fee. Check one-way charges, border restrictions, ferry restrictions and any required authorisation.
Opening hours and late arrival A late flight or delayed journey can affect collection, particularly at smaller branches. Check desk opening hours, flight-number requirements and any late-arrival conditions or charges.

Compare car hire offers like for like

When two rentals have similar prices, look at what you actually receive for that price. An offer with unlimited mileage, a full-to-full fuel policy, flexible cancellation and a lower deposit may suit your trip better than a slightly cheaper offer with more restrictive conditions.

It can help to compare four figures separately: the total rental price, the amount payable now, the amount payable at collection and the security deposit required on your card.

Then compare the non-price conditions: mileage, fuel, driver age, insurance excess, cancellation, payment-card requirements, collection arrangements and any extras you require.

Compare the collection arrangements

Where and how you collect the vehicle can be just as important as the price. Check the collection method when comparing otherwise similar offers.

Collection type What to compare
Airport terminal desk Terminal location, opening hours and any instructions for reaching the rental desk.
Airport rental centre Whether a bus, train, shuttle or walk is required from the arrivals terminal.
Off-airport shuttle Shuttle meeting point, frequency, transfer time and operating hours.
City branch Opening hours, transport to the branch and arrangements for returning the vehicle.
Different return location One-way charge, permitted route and exact return branch.

Choose the right vehicle category for your trip

Before comparing individual car hire offers, choose a vehicle category that suits your journey. The right category depends on how many people are travelling, how much luggage you have, where you will be driving and how much space and comfort you need.

Once you have selected a suitable category, you can compare the available offers within that category by price, fuel policy, mileage, deposit and other rental conditions.

  • Mini and economy cars: often suit one or two travellers, short journeys and city driving where easier parking and manoeuvrability are useful.
  • Compact and intermediate cars: can provide a useful balance of passenger space, luggage room and comfort for couples, small families and longer journeys.
  • Full-size and estate cars: may suit families or groups carrying several suitcases and those planning longer road trips.
  • SUVs: can offer additional passenger and luggage space, but check the actual capacity shown rather than assuming every SUV will suit a large group.
  • MPVs and larger passenger vehicles: are worth considering when travelling with a larger family or group, but make sure there is enough luggage space when all seats are occupied.
  • Automatic transmission: select an automatic category if required rather than assuming an automatic vehicle will be available within a manual category.
  • Electric vehicles: consider whether charging will be practical for your route and check the charging and return requirements attached to the rental.

Vehicle names shown in search results are usually examples of the category, so a particular make or model may not be guaranteed. Check the passenger, luggage and transmission details shown for the offer and look for wording such as “or similar”.

Why the cheapest-looking offer may not be the cheapest overall

Headline prices are useful for narrowing your search, but they do not tell the whole story. For example, an offer may initially appear cheaper but include a mileage restriction, a less suitable fuel policy, a higher deposit or a driver-age surcharge.

Another offer may cost slightly more but include unlimited mileage, more flexible cancellation or conditions that are better suited to your planned journey. The aim is therefore to compare the complete rental offer rather than choosing solely by the first price shown.

Compare driver age requirements and charges

Driver age is an important part of a car hire comparison. Rental providers can set minimum and maximum age requirements, and some vehicle categories may have different age limits.

Younger drivers may face a young-driver surcharge, while some suppliers may apply conditions or additional charges to older drivers. Enter the correct age when searching so the available offers are relevant to the driver who will collect the car.

Compare the fuel policy carefully

The fuel policy determines how much fuel should be in the vehicle when you collect it and how much should remain when you return it. This can affect the final cost of the rental.

A full-to-full policy generally means collecting the vehicle with a full tank and returning it full. Other arrangements may involve pre-purchased fuel, partial tanks or refuelling charges. Check the exact policy shown for each offer.

Compare unlimited mileage with mileage allowances

Mileage can make a significant difference if you plan to drive long distances. Some rentals include unlimited mileage, while others provide a daily or total allowance.

If mileage is restricted, check both the included allowance and the charge for additional kilometres or miles. A lower-priced offer with limited mileage may not represent better value for a road trip.

Compare the security deposit and payment-card rules

The security deposit is separate from the rental price. The rental provider may place a temporary authorisation or hold on the main driver's payment card when the vehicle is collected.

Deposit amounts and card requirements can vary substantially between rental providers. Check the required deposit, the accepted card types and whether the card must be in the main driver's name before choosing an offer.

Recheck the rental conditions before you book

Once you have compared the offers and selected the one that suits your trip, take a final look at the rental conditions before confirming the booking.

Make sure the driver's age and licence meet the provider's requirements, that you will have the correct identification and accepted payment card at collection, and that sufficient funds or credit will be available for the security deposit.

Also recheck the collection time and location, fuel policy, mileage, cancellation conditions and any extras or route restrictions that apply to your journey.

If mandatory rental conditions are not met at collection, the rental provider may refuse to release the vehicle.

Car Hire Comparison FAQs

What should I compare when choosing a hire car?

Compare the total price, rental provider, vehicle category, fuel policy, mileage allowance, driver age requirements, security deposit, insurance excess, cancellation conditions, payment-card requirements and collection arrangements.

Is the cheapest car hire offer always the best value?

Not necessarily. A lower-priced offer may have limited mileage, a different fuel policy, a higher security deposit or additional charges. Compare the complete rental conditions rather than relying only on the displayed price.

Can the driver's age affect the car hire price?

Yes. Rental providers can have minimum and maximum driver age requirements, and some offers may include young-driver, senior-driver or other age-related surcharges. Enter the correct driver age when searching and check the conditions before booking.

Why should I compare the fuel policy?

Fuel policies determine how the vehicle is supplied and how it should be returned. Refuelling charges or different fuel arrangements can affect the total cost, so compare the fuel conditions between offers.

Why does the security deposit matter?

The rental provider may place a temporary hold on the main driver's payment card. The required deposit can vary significantly between offers, so check both the amount and the accepted card type.

Does every car hire offer include unlimited mileage?

No. Some offers include unlimited mileage while others have a daily or total allowance. If you plan a long journey, check the mileage limit and any charge for exceeding it.

Why should I recheck the rental conditions before booking?

Rental providers can require the main driver to meet specific licence, age, identification, payment-card and deposit conditions. Check these requirements carefully before booking. If mandatory conditions are not met at collection, the rental provider may refuse to release the vehicle.

Can I cancel a car hire booking?

Cancellation conditions vary by offer. Check the exact cancellation deadline, refund terms and any non-refundable amount before booking.

Is Car Hire Trawler the same company as CarTrawler?

No. Car Hire Trawler is an independent comparison website. Its car hire search and booking journey is powered by the CarTrawler platform.
