Cheap Sixt Car Rental Deals at Clapham High Street, London

Research fuel prices in the area where you'll return the vehicle. Filling up at a local station may be cheaper than paying for fuel through the rental company, especially if they charge higher rates.

If you plan to park at the station, check out the parking options and fees ahead of time for convenience.

Some rental agreements come with mileage limits, while others offer unlimited mileage. Make sure to review the mileage policy to avoid unexpected fees.

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'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.

Many rental companies require payment by credit card and may not accept debit cards. If you only have a debit card, check the rental company's payment policies in advance and look for suitable options.

When renting a car, understand the fuel policy. A 'Full-to-Full' policy means you return the car with a full tank, while 'Same-to-Same' means you return it with the same level of fuel. Full-to-Full is often more cost-effective.

Pick a time that aligns with your flight arrival to avoid any complications from delays.
