Cheap Alamo Car Rentals at London Heathrow Airport, LHR

Most rental companies will require a credit card for the deposit, which is typically frozen in your account. Make sure to inquire about the specific deposit amount and the policy for releasing the freeze.

Ask if there are extra charges for picking up at the airport versus off-site locations.

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

If returning your rental at the airport, be aware of the parking policies and any fees involved.

When renting a car, understand the fuel policy. A 'Full-to-Full' policy means you return the car with a full tank, while 'Same-to-Same' means you return it with the same level of fuel. Full-to-Full is often more cost-effective.

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.

Many rental companies require payment by credit card and may not accept debit cards. If you only have a debit card, check the rental company's payment policies in advance and look for suitable options.
