Hiring a car can be one of the best ways to explore your holiday destination on your own terms — whether you’re travelling around the UK or heading abroad. But for all the freedom it offers, car hire can come with hidden costs and unnecessary extras if you’re not careful.
At Einsure, we help drivers make smarter choices. So, before you collect the keys, here are some essential tips to help you save money, protect yourself from unexpected charges, and make the most of your trip.
1. Shop Around Before You Book
Before committing to the first car hire company you come across, take a few minutes to compare prices using trusted comparison websites. This allows you to view different rental companies side-by-side, helping you find the most competitive rate for your needs.
You’ll often spot big price differences for the same vehicle class — especially if you’re booking during peak travel seasons. Be sure to compare:
Daily or weekly hire rates
Fuel policy (full-to-full is often the fairest)
Mileage limits
Deposit requirements
A little research up front can make a big difference to your budget.
2. Be Wary of Excess Damage Waiver Add-Ons
One of the most common upsells at the rental desk is the excess damage waiver — an optional insurance that reduces the amount you’d pay in the event of damage or theft. While this might sound reassuring, these policies are often hugely overpriced.
In many cases, you can buy standalone excess insurance from independent providers before your trip, often at a fraction of the cost.
If you don’t want to pay twice as much at the counter, politely decline and ensure you’re properly covered elsewhere. Always read the terms of both your rental agreement and any insurance policy to understand what is and isn’t included.
3. Inspect the Car Thoroughly – Inside and Out
Before driving away, take time to carefully inspect the hire car and document any existing damage. Even minor scratches, scuffs, or dents should be recorded.
Here’s how to do it properly:
Use your phone to take detailed photos of each side of the vehicle, the front, back, roof and wheels
Film a slow walkaround video for extra peace of mind
Don’t forget to check the interior, boot, windscreen, and the car’s underbody/valance
Look on the roof — a commonly missed area where damage may be unfairly blamed on you later
Ensure that any damage is noted on the paperwork before you sign. If the hire desk is busy, still take the time to document everything yourself.
4. Understand the Fuel Policy
Not all fuel policies are created equal. Some companies charge high rates for refuelling, while others may expect you to return the car empty — which usually means you’ll overpay for unused fuel.
Full-to-full is typically the fairest policy: you pick the car up with a full tank and return it the same way. Just remember to keep your fuel receipt in case there are disputes.
If you’re planning a longer stay in the UK — perhaps visiting for work, an extended holiday, or between cars — a short-term car subscription may be a more flexible and cost-effective option than traditional rental.
Subscription-based providers often include:
Road tax
Maintenance and servicing
Breakdown cover
Monthly rolling contracts with no long-term commitment
Unlike hire cars, subscriptions are designed for personal use over a longer period, often with more flexible mileage and fewer hidden charges. It’s worth comparing both options to see which suits your trip and budget best.
6. Bring the Right Documentation
To avoid delays or cancellation of your booking, make sure you have the required documents:
Your driving licence (check if you need an International Driving Permit)
A credit card in the main driver’s name for the security deposit
Booking confirmation and excess insurance (if bought separately)
ID or passport (especially for international rentals)
Check in advance if the hire company requires a DVLA licence check code — especially for UK rentals.
7. Return the Car on Time and Fully Fuelled
Late returns often lead to full-day charges, even if you’re only a few minutes behind schedule. Aim to return the car well before the agreed time and keep a photo of the fuel gauge to prove you’ve returned it full (if required).
Final Thought
Hiring a car should make your holiday easier, not more stressful. With a bit of preparation — and by avoiding common pitfalls like overpriced excess insurance or undocumented damage — you can enjoy your trip with confidence and clarity.
Compare deals, protect yourself with photos, and avoid unnecessary extras. And remember, for UK-based car insurance comparisons, Einsure.uk is here to help you find the best value every time.
