To contact APCOA, the company that manages the Heathrow Airport Drop-Off charge, you can use their dedicated customer service number at 0333 200 7459. They are generally available from Monday to Friday (08:00 – 20:00) and on weekends (08:00 – 17:00), though they are usually closed on Bank Holidays. For more immediate but non-urgent inquiries in 2026, the Live Chat feature on the APCOA Connect website is highly recommended; it is accessible via the small window on the bottom right of their contact page. If you are disputing a PCN (Penalty Charge Notice) for a missed payment, you must typically do so through their online appeals portal rather than over the phone to ensure a formal paper trail. Remember that the £5 drop-off fee is managed through an automated camera system (ANPR), so most issues can be resolved by logging into your account on the APCOA Heathrow website. For general parking at the airport (long stay or short stay), the contact methods may differ, but for anything specifically related to the "Forecourt" drop-off charge, the 0333 number is your primary point of contact.
