Yes, Heathrow Airport offers a 100% discount (free drop-off) for Blue Badge holders, but it is not automatic. As of January 2026, the standard terminal drop-off charge has increased to £7 per visit, and a new 10-minute maximum stay has been implemented. To avoid this charge, a Blue Badge holder (or someone dropping them off) must apply for the discount online either up to three months before the trip or by midnight the day after the drop-off occurs. The application requires the vehicle registration number, the Blue Badge number, and photos of the front and back of the badge. Once the application is successful, the vehicle is "whitelisted" for that specific trip, and the ANPR (Automatic Number Plate Recognition) cameras will not trigger a bill. Blue Badge holders are also exempt from the 10-minute time limit, allowing for a more relaxed transition for those with limited mobility. If you fail to register and do not pay the £7 fee, you will be issued a Parking Charge Notice (PCN) of £80, which is reduced to £40 if paid within 14 days.
