At Heathrow, book by terminal first and price second. The site is large enough that parking at the wrong terminal costs you a bus journey and twenty minutes you did not budget for.
Everything else about Heathrow parking follows from that one decision. Compare what serves your terminal before you compare anything on price.
Why does the terminal matter so much at Heathrow?
Because the terminals are miles apart, not minutes. Heathrow occupies a site comparable in size to a small town, and T4 and T5 sit at opposite ends of it.
At a single-terminal airport like Stansted you cannot get this wrong. At Heathrow it is the most common and most avoidable error, and it is why the terminal number on your booking confirmation deserves a second look the week before you fly.
What are the short stay car parks for?
Collections and drop-offs, not holidays. Each terminal has a multi-storey directly attached, a few minutes' walk from check-in.
They are priced by the hour. Across a fortnight that produces a number nobody enjoys, and the convenience you are paying for — a short walk — is worth far less spread across fourteen days than across two hours.
Use them to meet a delayed flight properly rather than circling the terminal roads.
Which car park suits a holiday?
Long stay, with the terminal shuttle. Heathrow's long stay car parks sit away from the terminals with dedicated buses, priced by the day.
This is the sensible benchmark for anything beyond a couple of nights, and it is what every other option should be measured against. Allow 25 minutes from parking your car to standing in the terminal — the drive is short, but the walk, the wait and the bus route are not.
Heathrow rewards long stay earlier than most airports, simply because the short stay tariffs are among the steepest in the country.
Is off-airport parking worth it at Heathrow?
On trips of about a week or more, usually yes. Heathrow has one of the largest independent parking markets in the UK, sitting a few minutes out along the M4 and M25 corridors.
The saving per day is real and it compounds. The checks matter more than at the official car parks:
Park Mark accreditation — the police-backed car park security standard
Which terminals the transfer actually serves — some operators cover only two or three
Transfer frequency and overnight running
Recent reviews rather than the lifetime average
That second point is Heathrow-specific and catches people out. An off-airport site serving T5 may not serve T4 directly.
When is meet and greet the right call?
Early departures, young children, heavy luggage, or a late-night return. You drive to a designated area at your terminal, hand the keys over, and walk into departures.
At Heathrow this is worth more than at a compact airport, because the alternative involves a car park, a bus and a walk through one of the largest terminal buildings in Europe. If any part of your trip is already difficult, this removes the part you have most control over.
What about the drop-off charge?
Heathrow charges for terminal forecourt drop-off, with free alternatives further out. If someone is driving you rather than you parking, that distinction is worth checking before you set off.
It also changes the maths on short trips. For an overnight where someone could drop you off, the free option plus a short shuttle may beat parking entirely.
A short answer by trip
Collecting someone — short stay at their terminal
One or two nights — short stay if the price is bearable, otherwise long stay
Three nights to a week — long stay
Over a week — off-airport, checking it serves your terminal
Early flight, children, or a lot of bags — meet and greet, at any length
Whichever you pick, book ahead. At Heathrow the gap between an advance rate and the gate rate is wider than the difference between most of these options, which puts the whole comparison in perspective.
