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're traveling with pets, verify the rental company's pet policies beforehand. While some allow pets, there might be specific fees or limitations.

Before renting, check if your personal auto insurance extends to rental cars. Many policies and credit cards offer rental coverage, helping you save on insurance costs.

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

Make sure you know the details of the roadside assistance included with your rental. This is crucial in case of breakdowns or accidents.

Before you return the vehicle, clarify the return procedures with the rental agency. Knowing where to drop off the car and any required inspections can make the process easier.

Ensure your rental agreement, ID, and insurance details are easily accessible throughout your rental period for quick access if needed.

Before you finalize your booking, see if the rental agency offers free cancellation. This can be helpful if your travel plans change unexpectedly.
