There is no long-term free parking at London Heathrow (LHR), but you can find very brief windows of free access for drop-offs and pickups. In 2026, the Long Stay Car Parks offer up to 30 minutes of free parking, which is the best option for meeting arriving passengers without paying the steep Short Stay fees. You must enter, stay less than 30 minutes, and exit; otherwise, daily rates apply. For "drop-offs" directly at the terminal curb, Heathrow charges a £5 Terminal Drop-Off Charge per visit, which must be paid online. There is no way to avoid this at the curb. If you are looking for free parking for the duration of a trip, some nearby residential streets in Feltham or Hounslow might not have restrictions, but this is highly risky due to local "permit only" zones and the potential for vandalism. Most travelers find that pre-booking an "Off-Airport" park-and-ride service is the most cost-effective compromise between the high cost of official parking and the insecurity of street parking.
