Yes, you can hire a car in Greece with a UK paper driving license, but you are legally required to hold an International Driving Permit (IDP) alongside it. Following Brexit, the rules for UK drivers in the EU became more standardized. While those with the modern "photocard" license usually do not need an IDP for short visits to Greece, the older paper-only licenses are not considered sufficient on their own by Greek authorities or insurance providers. Specifically, you will need a 1968 IDP, which can be obtained easily at most UK Post Offices for a small fee (around £5.50). When you arrive at the rental desk in Athens, Crete, or any other Greek destination, you must present your original paper license, your IDP, and your passport. It is also worth checking with your specific rental agency in advance, as some smaller local firms may have stricter internal policies regarding older license formats to ensure their insurance coverage remains valid in the event of an accident.
