At Heathrow Airport, you are strictly prohibited from stopping or waiting on the terminal forecourts for pick-ups due to security and traffic regulations. If you attempt to wait curbside, you risk a significant fine or having your vehicle removed. Instead, the "Short Stay" car parks are the designated pick-up points, but these are chargeable from the moment you enter (starting at approximately £7.50 for up to 30 minutes). If you are looking for a free option, you should use the Long Stay Car Park, where the first two hours are free. This is the ideal location to wait while your passenger clears immigration and collects their luggage. Once they are ready at the terminal, they can take the free shuttle bus to meet you at the Long Stay lot, or you can drive to the Short Stay car park for a quick, paid pick-up. Note that a "re-entry" fee or a 24-hour "no return" rule usually applies to the free period in Long Stay to prevent taxi and minicab idling.
