Car Hire in Knightsbridge, London, United Kingdom

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 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.

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.

Ensure that you have a valid driving licence with at least one year of driving experience. If you are a foreign driver travelling to London, an international driving permit may be required. Remember, hire rates can be higher for drivers under 25 or over 70

If someone else will drive, confirm the rental company's policy on additional drivers and any fees that may apply. Some might offer complimentary drivers under certain conditions.

Familiarize yourself with the fuel policy. A 'Full-to-Full' policy requires returning the vehicle with a full tank, while 'Same-to-Same' requires it to be returned at the same fuel level. Full-to-Full is generally more economical.

Before booking, review the rental agreement for any hidden fees such as airport surcharges, additional driver fees, or late return penalties. Understanding these can help you budget more effectively.

Before returning the car, clarify the return procedures with the rental agency. Knowing where to drop off the vehicle and any necessary inspections can ease the process.
