Car Rental in Mayfair, London, United Kingdom

When renting a car, especially after travelling by train, allocate extra time for pickup to account for possible delays. Most rental companies offer a 30-60 minute grace period. Sharing your train number can be helpful, but if you're running late, be sure to contact the rental provider to let them know.

Research toll roads on your travel route and familiarize yourself with their payment methods. Some rental agencies offer toll transponders for convenience.

Before leaving the rental location, check that the vehicle is stocked with essential emergency supplies such as a spare tire, jack, and first aid kit.

Be aware that some rental companies impose age restrictions or additional fees for drivers under 25. Make sure to check the company’s age policy when booking.

If you plan to share driving, check if the rental company allows a second driver and whether there are additional fees. Some companies offer free second driver options under certain conditions.

If sharing driving responsibilities, check the policies regarding additional drivers. Some companies charge fees for each extra driver, while others may include it for free under certain conditions.

If you're traveling with pets, confirm the rental company's pet policy before booking. Some companies allow pets but may have specific fees or restrictions, so it’s best to clarify in advance.

If you're looking for extra comfort or features, ask about upgrade possibilities at the rental desk. Often, there are discounted upgrades available at pickup.
