I think what you need to pay more attention to when renting a car in the UK is the issue of insurance and return. 1. Insurance: Conventional car rental contracts already include three major types of insurance: CDW – Collision Damage Waiver. , Theft Protection (TP – Theft Protection) and Third Party Liability (TPL – Third Party Liability). When renting a car, it is equivalent to having chosen these three major insurances, and there is no need to buy additional ones. However, it is important to note that collision insurance and theft insurance have a minimum liability, which is basically 1100-4000 euros. If the claim amount is less than 1100-4000 euros, the driver needs to bear it himself. Only compensation exceeding this amount will be paid by the insurance company. You may also consider purchasing a Super Cover plan (SC – Super Cover) to eliminate minimum liability. In the event of a collision or loss of the vehicle, the renter is generally not responsible for any liability (except for the roof, tires, chassis, and glass). Generally, when you pick up your car at a store, the store clerk may sell additional insurance and services. Before signing the formalities, be sure to carefully check whether the terms and amount of the car rental contract are consistent with the car delivery bill. 2. Return the car: A "rental day" includes 24 consecutive hours, and each day is calculated from the rental time. When the return time exceeds 24 hours, the rental company will charge an additional day's fee. But usually car rental companies will give guests a little grace time. For example, Hertz's grace time for returning a car is 29 minutes. Guests will only have to pay for an extra day if they fail to return the car after 29 minutes.
