Car hire conditions are the most important document to read before booking. They explain what is included, what is excluded, which documents you need, which card is accepted, how much deposit may be blocked, what excess applies and what rules you must follow during the hire.
Many problems at the rental desk happen because customers look only at the price and do not read the supplier terms. The conditions are where you find the practical details that decide whether an offer is suitable for your trip.
On gocarhire.co.uk, always check the important information for the vehicle and supplier before confirming. If you want a step-by-step booking overview, read our hassle-free car hire guide.

The key sections to read
| Section | What it tells you | Why it matters |
|---|---|---|

Documents and licence requirements
The main driver must bring the documents required by the supplier. This normally includes a valid driving licence, ID and booking voucher. International travellers may need additional documents depending on their licence and destination.
Use our car hire documents checklist and International Driving Permit guide if you are unsure.
Deposit, card and excess
The conditions should clearly state the security deposit, the accepted card type and the excess. Do not assume that a debit card is accepted unless the offer says so. Do not assume that buying extra protection removes the need for a deposit.
For more detail, read our guides on lowest car hire deposits, insurance and excess and car hire without a credit card.
Fuel, mileage, borders and returns
Fuel policy, mileage and return rules can create extra costs if misunderstood. Check whether mileage is unlimited or capped, whether the car must be returned full, and whether cross-border travel or ferries are allowed.
