Hiring a car can make your trip much easier whether you’re driving through the Lake District, heading to the South of France, or exploring the U.S. on a road trip. But UK travellers often face hidden charges, unfamiliar rules, or booking mistakes that push up costs. If you want to drive with confidence (and stay on budget), here are six must-know tips before you collect the keys.

1. Double-Check Your Licence and ID Requirements
Before you book, make sure you know what documents are required for driving abroad. Most UK driving licences are accepted in Europe and the U.S., but some countries may also ask for an International Driving Permit (IDP). Also, many car hire companies require a credit card in the driver’s name for security. Always read the fine print, especially if you plan to book online from the UK for pickup abroad.
2. Watch the Mileage Limits (They’re Not Always Unlimited)
Not all rentals offer unlimited mileage. Some cheaper deals, especially in rural or island locations, may include daily mileage caps. If you go over, you’ll pay a per-mile charge. For UK travellers planning long drives (like from London to the Highlands), make sure you choose a car hire with unlimited mileage or compare mileage rules when booking on holidaycars.com.
3. Fuel Rules Can Cost You — Know Yours
UK travellers are often caught out by different fuel policies. The most cost effective is “full-to-full”: you pick the car up with a full tank and return it the same way. Be wary of “pre-purchase” or “full to empty” fuel plans, where you’re charged for a full tank regardless of how much you use. Always take a photo of the fuel gauge when you return the vehicle.
4. Avoid Booking by Price Alone
We all love a bargain but with car hire, the cheapest deal isn’t always the best. Look at what’s included: Does the quote cover insurance? Are there cancellation fees? Is there a young driver surcharge? Comparing deals lets you see what’s included and what’s not, so you won’t get caught out.
5. Don’t Assume Automatic
If you’re booking outside the UK, especially in Europe, manual cars are the default and automatics can be more expensive or in shorter supply. If you’re not comfortable driving manual, make sure to filter for automatic vehicles early when comparing. Last minute upgrades can be costly or unavailable.
6. Bring a Travel Card for Fuel & Tolls
If you’re driving abroad, especially in countries like France or Spain, having a travel friendly payment card with no foreign fees can save money at toll booths and petrol stations. Avoid using debit cards with international charges. Some prepaid travel cards also offer car hire insurance as another way to save.
From license requirements to local driving customs, UK travellers have a few extra things to think about when hiring a car. But with the right planning, you can avoid surprises and hit the road with confidence wherever you’re headed next.
