The majority of rental agents have a minimum age requirement of 25 to hire car at standard rates. Under 25’s can usually hire a car subject to a young driver fee (payable on collection, typically around £15-20 per day). 21 is a typical minimum age, however some agents set 23 as the minimum age. All rental agents require that you have held your licence for at least 12 months. We offer an under 25 car hire discount to help young drivers offset the young driver surcharge.
