While named "Short Stay," these car parks at Heathrow (located at Terminals 2, 3, 4, and 5) actually allow for a maximum stay of up to 99 days if you pre-book your spot online. For those who simply "drive up" without a reservation, there is technically no hard time limit—you can stay as long as you like—but you will be charged the daily drive-up tariff for every 24-hour period, which is significantly more expensive than the pre-booked rate. In early 2026, the drive-up rate for a 24-hour stay reached approximately £98, with each additional 24-hour period adding another £98. The Short Stay car park is primarily designed for passenger pick-ups, drop-offs, or travelers on 1-2 day business trips who value the convenience of being just a two-minute walk from the terminal doors. If you plan to be away for more than 24 hours, Heathrow's "Long Stay" or "Business" parking options are much more cost-effective, though they require a short shuttle bus ride. For 2026 travelers, the "Short Stay" remains the ultimate "premium convenience" option, provided you are willing to pay the premium price for that immediate terminal access.
