Cheap AVIS Car Rentals at London Heathrow Airport, LHR

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.

When renting a car, it's crucial to understand the different insurance options available. Selecting the right insurance can protect your finances in case of an accident. Common options include Collision Damage Waiver (CDW) and liability insurance, so make sure to confirm the required coverage with the provider.

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

To save on refueling costs when departing from Airport, look for deals with a 'full to full' tank fuel policy, or even better, a free tank fuel policy, as opposed to a 'half-full to full' one.

Before your trip, confirm if your rental includes roadside assistance. This can be crucial in case of breakdowns or emergencies during your rental period.

Allow for possible delays at the rental desk, particularly during busy travel times.

Determine if your rental provider has an airport desk or if you’ll need to take a shuttle to reach them.

Have your driver’s license, credit card, and rental confirmation ready to speed up your pickup.
