Yes, Uber is permitted to pick up passengers at Heathrow Terminal 2, but there is a specific designated area you must use. Unlike a traditional taxi that you can hail at the curb, Uber drivers are required to meet their riders in the Short Stay Car Park 2. For Terminal 2, the pickup point is typically located on Level 4, Row H. After you request your ride in the Uber app, it will provide step-by-step walking directions to the car park. You will need to take the elevators or escalators from the arrivals hall to the car park area. Be aware that Heathrow charges a "terminal drop-off and pick-up fee," which is usually included in your final Uber fare. For the smoothest experience, it is best to only request your ride once you have collected your luggage and are actually walking toward the car park, as drivers are not allowed to wait at the terminal forecourt.
