Book Cheap AVIS Car Hire Deals in Harrow, London, United Kingdom

Some rental companies offer a free tank of fuel with your rental. Be sure to understand the terms, including how much fuel you need to return the car with and any potential fees for not meeting these conditions.

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.

Before you book, review the rental agreement for any hidden fees, such as airport surcharges, additional driver costs, or penalties for late returns. Awareness helps in budgeting appropriately.

Take a moment to familiarize yourself with the vehicle's controls and features before driving off. Knowing how to operate essentials like headlights, wipers, and navigation systems can enhance safety and convenience.

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.

Before renting a car, check if your personal car insurance covers rental losses. Many personal auto insurance policies and credit cards offer coverage for rentals, which could save you from extra insurance fees.

When hiring a car, especially if you’re arriving in Harrow, London by flight, plan for extra time at pickup to accommodate any potential delays. Suppliers like AVIS typically offer a grace period of 30-60 minutes. Providing your flight number can be helpful, but if you’re running late, be sure to call the supplier to inform them.

Before leaving the rental lot, check if the vehicle has essential emergency supplies, such as a spare tire, jack, and first aid kit.
