Cheap Firefly Car Hire Deals at Heathrow Terminals 2 & 3, London

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 don’t find what you need at Heathrow Terminals 2 & 3 with Firefly, you might discover more car hire options in London, which can occasionally be cheaper. However, keep in mind that the additional cost of transferring from Airport to London might result in higher overall expenses compared to picking up your rental car directly at the airport.

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.

Before leaving the rental location, inspect the car for any existing damage and ensure it’s documented. Take photos if necessary to avoid disputes when returning the vehicle.

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.

Select a pickup location that is convenient for you. Some rental companies offer locations within the airport for quick access, while others may require shuttle transportation.

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

If you plan to park at the station, check out the parking options and fees ahead of time for convenience.
