Best Car Hire Companies: How to Compare Rentals & Avoid Hidden Fees

Looking for the best car hire companies for your next holiday? Renting a car can give you the freedom to explore new destinations, visit attractions outside city centres and travel at your own pace.

However, the cheapest advertised rental price is not always the best deal. Insurance excesses, security deposits, fuel policies and additional driver charges can significantly affect the total cost.

In this Lake Journey guide, we’ll explain how to compare car hire companies, choose the right vehicle and understand the rental conditions before booking.

2. How to Compare Car Hire Prices Properly

When comparing rental companies, use the same collection location, return location, dates, times and vehicle category wherever possible.

Pay attention to:

  • Total rental price: Compare the final amount rather than the daily headline rate.
  • Included mileage: Check whether mileage is unlimited or restricted.
  • Fuel policy: Understand how much fuel you must return with the car.
  • Insurance: Check what protection is included and the applicable excess.
  • Deposit: Confirm the security deposit and accepted payment cards.
  • Collection location: Airport desks and off-airport branches may have different costs.
  • Cancellation: Review refund conditions and deadlines.

Also check opening hours, especially if your flight arrives late at night or early in the morning.

Lake Journey Tip:

Compare the total cost for the entire rental period, including mandatory fees and any extras you genuinely need. A low daily rate can become expensive once additional charges are included.

3. Car Hire Insurance, Excess and Security Deposits

Insurance and deposits are among the most important details to understand before collecting a rental vehicle.

Collision Damage Waiver

A collision damage waiver, often called CDW, may limit your financial responsibility for certain types of damage. It is not necessarily comprehensive insurance and can have exclusions.

Insurance Excess

The excess is the amount you may have to pay if the vehicle is damaged or stolen under circumstances covered by the rental agreement. The amount varies by provider and vehicle.

Excess Protection

Some companies offer additional protection to reduce the excess. Independent excess reimbursement policies may also be available, but they can work differently from protection purchased directly from the rental company.

Security Deposit

Many rental companies place a temporary authorisation or hold on a payment card. Check the required deposit, accepted card type and how long it may take for funds to become available again.

Read the terms carefully, including exclusions for tyres, windscreens, underbody damage and lost keys.

4. Choosing the Right Rental Vehicle

The right car depends on your destination, passenger numbers, luggage and planned driving.

Economy Cars

Compact vehicles can be suitable for city breaks, couples and shorter journeys. They may also be easier to park in busy areas.

Family Cars

Travelling with children or several suitcases? Compare vehicles with sufficient boot space and passenger seating.

SUVs and Larger Vehicles

Larger vehicles may offer extra space, but they can cost more to rent and fuel. Check whether the vehicle suits local roads and parking arrangements.

Automatic and Manual Cars

If you prefer an automatic vehicle, make sure your booking explicitly specifies automatic transmission. Vehicle availability varies by destination.

Remember that many rentals are booked by vehicle category rather than a guaranteed make and model.

5. Car Hire Fees and Charges to Watch For

Additional fees can make a significant difference to the total rental cost.

  • Additional drivers: A fee may apply for each extra driver.
  • Young driver charges: Drivers below a specified age may pay more.
  • One-way rentals: Returning the car to a different location may cost extra.
  • Airport surcharges: Some rental locations include additional airport-related fees.
  • Late returns: Returning the vehicle outside the agreed time can result in charges.
  • Fuel charges: Returning the car with insufficient fuel may be expensive.
  • Cleaning charges: Excessive soiling may incur fees.
  • Cross-border travel: Driving into another country may require permission and additional cover.
  • Equipment: Child seats, navigation devices and other extras may cost more.

Also check whether toll roads, congestion charges, parking fees and traffic fines are your responsibility.

6. Car Hire Booking and Collection Checklist

Before booking and collecting your vehicle, remember to:

  • Compare prices using identical rental dates and locations.
  • Check the driver’s minimum age and licence requirements.
  • Confirm whether an International Driving Permit is required.
  • Read insurance, excess and deposit conditions.
  • Check the fuel and mileage policies.
  • Confirm accepted payment cards and deposit requirements.
  • Review the cancellation and late-return policies.
  • Check collection and return opening hours.
  • Inspect the vehicle and photograph existing damage before departure.
  • Keep your rental agreement and emergency contact details accessible.

When returning the vehicle, follow the agreed procedure and retain evidence of its condition and fuel level where practical.

7. Frequently Asked Questions

Which car hire company is the best?

There is no single best company for every traveller. Compare the total price, vehicle category, branch reviews, insurance conditions and customer support for your destination.

Is it cheaper to book car hire in advance?

Booking ahead can provide more choice and sometimes better prices, particularly during busy holiday periods. However, rates vary, so compare options and cancellation conditions.

Do I need a credit card to hire a car?

Many rental companies require a credit card in the main driver’s name, particularly for the security deposit. Some accept debit cards under specific conditions. Check the supplier’s rules before booking.

Does car hire include insurance?

Some level of cover is commonly included, but the type, excess and exclusions vary. Always review the rental agreement to understand your financial responsibility.


Final Thoughts

Choosing the right car hire company involves more than comparing daily rental prices. Insurance excesses, deposits, fuel policies, mileage limits and collection arrangements can all affect your experience.

By comparing the full rental terms and choosing a suitable vehicle, you can make a more informed decision and reduce the risk of unexpected costs.
