Hiring a car can give you the freedom to explore a destination at your own pace, but the cheapest advertised rental isn’t always the cheapest once insurance, fuel, deposits and optional extras are considered.

The right car hire tips can help you compare the real cost before booking and avoid expensive surprises at the rental desk.

From checking excess insurance to choosing the right fuel policy, here are 10 car hire tips that could help you save money on your next trip.

1. Compare Car Hire Before You Book

The first of our car hire tips is straightforward: compare several options rather than automatically booking with the first company you recognise.

Car hire prices can vary according to:

Destination
Travel dates
Vehicle category
Pick-up location
Rental duration
Driver age
Availability

One of the easiest car hire tips to follow is to start looking once your travel plans are reasonably firm, particularly during busy holiday periods.

But don’t compare the headline rental price alone.

Look at the total price and check what is included before deciding which deal offers the best value.

You can compare car hire through TravelHype to explore your options.

2. Check the Insurance Excess

Understanding the insurance is one of the most important car hire tips.

Many rentals include some form of Collision Damage Waiver, commonly known as CDW, but this doesn’t necessarily mean you have nothing to pay if the vehicle is damaged.

There may be a substantial excess.

The UK government’s car-rental guidance recommends checking both the excess and deposit before booking and considering whether you could afford the excess if the car were damaged.

Standard cover can also exclude certain types of damage, potentially including tyres or glass.

Among the most important car hire tips is checking the following before booking:

What insurance is included
The damage excess
Theft excess
What’s excluded
Deposit required
Whether additional cover is optional

Don’t assume the cheapest rental includes equivalent protection to a more expensive one.

For more information, read the government’s car rental advice for consumers.

3. Compare Independent Excess Insurance

You don’t necessarily have to buy additional excess protection from the rental desk.

Independent car hire excess insurance can sometimes cost substantially less.

Which? reported in 2026 that the independent excess policies it reviewed were generally considerably cheaper than cover purchased directly from rental companies.

Another of our car hire tips is to understand exactly how independent excess cover works before buying it.

The rental company may still require you to provide a deposit.

If damage occurs, it may charge you and leave you to reclaim the eligible amount from your independent insurer afterwards.

That’s different from some rental-company products that reduce the amount you’re liable for directly.

One of the most useful car hire tips is therefore to compare the cover, exclusions and claims process as well as the premium.

4. Compare Airport and Off-Airport Locations

Don’t assume the airport desk will always offer the best deal.

Search other convenient rental locations in the area as well.

An off-airport branch may occasionally offer a lower total price, while an airport location may be better value once transport to another branch is considered.

Compare:

Rental price + fees + transport to the rental location

rather than the vehicle price alone.

Also check opening hours carefully.

A cheaper branch isn’t much use if it closes before your flight arrives or requires an expensive taxi journey.

These car hire tips are about reducing the cost of the whole journey, not simply finding the lowest number in the search results.

5. Check Membership and Loyalty Discounts

Before paying, check whether memberships you already hold provide a car hire discount.

These could include:

Breakdown memberships
Airline frequent-flyer programmes
Hotel loyalty schemes
Credit-card benefits
Employer or professional memberships

For example, The AA currently advertises car hire discounts of up to 15% with National, 10% with Enterprise and 5% with Alamo.

You can check the current AA car hire offers before booking.

Offers and terms can change, so don’t assume an old discount is still available.

And always compare the discounted rate with other available prices. A membership discount doesn’t automatically make that supplier the cheapest.

6. Choose the Right Size Car

Booking more car than you need can increase the rental price and potentially your fuel or charging costs.

Before choosing a vehicle, think realistically about:

Number of passengers
Suitcase space
Driving distances
Road conditions
Parking
Fuel economy

A compact car can make sense for a couple travelling around European cities, while a family carrying several large suitcases may genuinely need something bigger.

Don’t automatically pay for an SUV or premium model because it looks more comfortable on the booking page.

Among the simplest car hire tips is to choose the smallest vehicle category that comfortably meets your actual requirements.

7. Think Carefully Before Choosing an Electric Car

An electric hire car can be a good option, but it isn’t automatically the cheapest choice.

Your decision should depend on the journey.

Before hiring an EV, check:

Charging availability
Charging prices
Expected mileage
Accommodation charging
Return-charge requirements
Driving range

An EV may work particularly well if your hotel provides convenient charging or your itinerary involves predictable journeys with good charging infrastructure.

For other trips, finding chargers could add time and expense.

Compare the complete cost rather than assuming petrol, diesel, hybrid or electric will always be cheapest.

Good car hire tips should work for the trip you’re actually taking.

8. Look for a Full-to-Full Fuel Policy

Fuel policies can have a significant effect on the final rental cost, making this one of the car hire tips worth checking before you book.

A full-to-full policy generally means you collect the vehicle with a full tank and return it full.

This gives you control over where you purchase the replacement fuel.

Other policies may require you to pre-purchase fuel or involve additional fuel-related charges.

The government’s car-rental guidance specifically recommends checking the fuel policy because some rental providers may require customers to purchase fuel from them.

Before driving away, confirm:

Fuel level
Return requirement
Refuelling charges
Location of a convenient filling station

If your agreement is full-to-full, refuel close enough to the return location to comply with the policy and keep the receipt where appropriate.

This is one of the car hire tips that can prevent a cheap rental becoming unnecessarily expensive at the end.

9. Avoid Paying for Extras You Don’t Need

Optional extras can quickly increase the cost of car hire.

Common examples include:

Additional drivers
Child seats
GPS navigation
Additional insurance
Roadside products
Snow equipment
Wi-Fi devices

Some extras may be necessary, and certain equipment can be legally required depending on the destination and conditions.

Others may be unnecessary.

For example, if you’re comfortable using offline maps or mobile navigation, paying separately for a GPS unit may offer little value.

Check the rules at your destination before taking your own child seat or other equipment.

One of the easiest car hire tips to follow is simply to decide which extras you actually need before reaching the rental counter.

10. Photograph the Car Before and After the Rental

Saving money isn’t only about finding a cheaper booking.

It’s also about reducing the risk of being charged for damage you didn’t cause.

When collecting the car, inspect it carefully.

Check:

Wheels
Tyres
Bumpers
Doors
Windscreen
Mirrors
Roof where visible
Interior

Make sure existing damage is recorded on the rental agreement.

Take clear photographs or video before leaving the rental location, preferably showing the condition of all sides of the vehicle.

Do the same when returning it.

If possible, have the vehicle inspected and obtain confirmation of its return condition.

Damage charges are a significant source of car-rental complaints, and the government’s guidance recommends checking the vehicle and taking photographs.

Of all the car hire tips in this guide, this is one of the easiest to follow and could prove extremely valuable if a dispute occurs later.

Check the Deposit Before Booking

One of the car hire tips that’s easy to overlook is checking the deposit before choosing your rental.

A cheap rental may require a large amount to be temporarily held on your card.

That money can then be unavailable for other spending during your holiday.

Check:

Deposit amount
Accepted card types
Whose name the card must be in
When the hold is released
Currency used

Don’t arrive at the rental desk assuming any debit or credit card will be accepted.

Read the supplier’s payment requirements before travelling.

Check Mileage Limits

Unlimited mileage can be useful if you’re planning a road trip, but not every rental includes it.

Some agreements set a mileage or kilometre allowance and charge extra if you exceed it.

Estimate how far you’re likely to drive before booking.

A slightly more expensive rental with unlimited mileage could work out cheaper than a low headline rate with a restrictive allowance.

This is particularly important if the hire car is central to your holiday rather than simply being used for airport transfers.

Watch for One-Way Fees

Picking a car up in one city and returning it somewhere else can be convenient.

It can also cost more.

Rental companies may charge a one-way or drop-off fee when the vehicle is returned to a different location.

For a road trip, compare:

One-way rental
Returning to the original location
Alternative transport for one part of the journey

Don’t rule out a one-way rental if it improves your holiday substantially, but include the fee when comparing prices.

Read the Terms Before You Pay

One of the simplest car hire tips is to read the important conditions before paying rather than waiting until you’re standing at the rental desk.

Before booking, check:

Cancellation policy
Deposit
Insurance excess
Fuel policy
Mileage
Driver age restrictions
Additional-driver charges
Cross-border travel
Required documents
Payment-card requirements
Pick-up and return times

The Competition and Markets Authority has previously taken action over transparency in the car hire sector, including compulsory charges, deposits, insurance excesses and fuel policies.

Current UK pricing rules also require unavoidable charges to be included in the total price presented to consumers rather than hidden until later in the purchasing process.

Even so, optional products and the terms attached to your rental can make a substantial difference to what you eventually pay.

10 Car Hire Tips to Save Money: The Verdict

The best car hire tips aren’t complicated.

Compare the total price, understand the insurance excess, check independent cover, review the fuel policy and avoid paying for extras you don’t need.

Before booking:

Compare several car hire options.
Check the insurance excess and deposit.
Compare independent excess insurance.
Look at different pick-up locations.
Check memberships for discounts.
Choose an appropriate vehicle size.
Decide whether an EV suits your journey.
Understand the fuel policy.
Remove unnecessary extras.
Photograph the vehicle before and after your rental.

Most importantly, don’t judge a deal by its headline price alone.

A slightly more expensive rental with a lower deposit, sensible fuel policy and the right inclusions can provide better value than the cheapest advertised option.

When you’re ready for your next trip, you can compare car hire through TravelHype, as well as find flights and search for hotels.
