Cheap Sixt Car Hire Deals at Heathrow Terminals 2 & 3, 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.

Ask the rental company about their specific pickup and drop-off processes for a hassle-free experience.

Before booking, check for any promotional offers or discounts that may be available. Many rental companies provide seasonal deals or discounts for early bookings.

Before your journey, browse online to see what cars are currently available to find your preferred model.

If you plan to share driving, check if the rental company allows a second driver and whether there are additional fees. Some companies offer free second driver options under certain conditions.

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.

To save on refueling costs when departing from Heathrow Terminals 2 & 3, 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.

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.
