Millions of Britons heading overseas this summer could be paying far more than they need to for their car hire.

That’s the warning from our consumer expert Jane Hawkes, who is advising holiday makers to book car hire well in advance and be confident in saying no to upselling at the desk.

Jane, who runs the consumer advice website www.ladyjaney.co.uk says the biggest costs can come from purchasing excess protection directly from a rental company as well as returning the car with an empty tank.

A hire car abroad can bring real freedom on your holiday, particularly if you’re not staying in a resort, but it can also mean the cost of your trip soars.

It’s important that holiday makers don’t just compare the initial cost of the car when they are looking to hire, as it’s the hidden extras where companies can really make their money.

Whether it’s getting you to use their insurance or paying their price per litre for fuels, that bargain car could turn into a big bill.

And with families already facing higher holiday costs, understanding what is optional, what is genuinely worthwhile, and how to avoid unnecessary rental desk charges has never been more important.”

Here are my Ten Tips to avoid car hire rip offs


Book in advance

Hiring a car well before you travel is usually one of the easiest ways to save money. Prices often increase as availability decreases, particularly during school holidays and peak summer months. Booking early also gives you a wider choice of vehicles so you're less likely to end up paying extra for a larger car simply because the cheaper models have sold out.

Compare more than just cost

The cheapest deal isn't always the best value. Take the time to look beyond the headline rate and compare what's actually included, such as insurance, mileage allowances, fuel policies, airport collection fees and any additional charges. It's also worth reading recent customer reviews as excellent customer service can make all the difference if something goes wrong during your trip.

Take your time sorting insurance

Car hire insurance can be confusing and many drivers only realise how high the excess is when they collect the vehicle. Rental companies often offer expensive additional cover at the desk but you may find it much cheaper to arrange standalone excess insurance before you travel. Whatever option you choose, make sure you understand exactly what is and isn't covered before you set off.

Opt for ‘Full to Full’

Opt for a 'Full to Full' so you collect the car with a full tank and simply return it full, making it much easier to avoid inflated refuelling charges. Be wary of prepaid fuel or 'Full to Empty' arrangements, as you may end up paying for fuel you never actually use.

Record the condition of the car

Before leaving the rental depot, take a slow video of the entire vehicle, including every panel, wheel, windscreen and the interior. Time-stamped photos and videos can provide valuable evidence if you're later accused of causing damage that was already there. It only takes a few minutes and could save a lengthy dispute after your holiday. Don't assume the rental company has already noted every mark on the vehicle. Walk around carefully and inspect for scratches, dents, wheel scuffs, cracked lights and stone chips.

Be wary of expensive (unnecessary) extras

When collecting your vehicle, you'll often be offered a range of optional extras such as sat navs, Wi-Fi devices, child seats and premium breakdown cover. While some may be useful, others can significantly increase the cost of your hire. Consider whether you genuinely need them or whether your own smartphone, navigation apps or travel equipment will do the job just as well.

Pay by credit card

Where possible, use a credit card to pay for your hire car and security deposit. Many rental companies insist on one, and credit cards can also provide additional consumer protection if things go wrong. Just remember that the company may place a temporary hold on part of your available credit until the vehicle has been returned and inspected.

Understand excesses

Many people focus on the daily rental cost but overlook the excess, which can run into thousands of pounds. Before booking, find out exactly how much you would be liable for if the vehicle was damaged and whether items such as tyres, wheels, windscreens or the underbody are excluded from cover. Knowing this in advance allows you to decide whether additional protection is worthwhile.

Pay in local currency

If you're asked whether you'd like to pay in pounds instead of the local currency, it's usually best to decline. This service, known as Dynamic Currency Conversion, often uses a poorer exchange rate than your own card provider would offer. Paying in the local currency can often save you money without any extra effort.

Don’t feel pressured

Rental desk staff may recommend upgrades or additional insurance, but these are often optional products. Take your time, ask questions and don't feel pressured into agreeing simply because you're worried about holding up the queue. If you've already arranged suitable insurance, politely decline anything you don't need.
