One Stop Parking Discount Code 2026 — Heathrow

What One Stop Parking is, and how it works

On-airport parking sits inside the airport boundary, within walking distance or a short internal bus ride of the terminal. You keep your keys. It is the most expensive way to pre-book at most UK airports and the fastest at all of them.

At Heathrow Airport specifically, the field runs from £47 to £66 for eight days, which is the range any quote here has to be read against. Heathrow is the only airport in this set where the top search is a price query rather than a code query — people arrive looking for cheap parking, not for a voucher — which is why this page leads with the price table rather than the code.

One Stop Parking covers Terminals 2, 3, 4 and 5 at Heathrow. Heathrow's four terminals are far enough apart that booking a car park for the wrong one is a genuine problem rather than an inconvenience — unlike Gatwick, there is no three-minute shuttle to correct it. Terminal 5 sits at the western end with its own dedicated car parks; Terminals 2 and 3 share the central terminal area; Terminal 4 sits to the south. Free inter-terminal transfers exist by rail but add 20 to 30 minutes.

What One Stop Parking should cost at Heathrow

We price the airport rather than guess at the operator. Below is every product we track at Heathrow on the same eight-day stay; the on-airport rows are the ones to read a One Stop Parking quote against.

The spread at Heathrow is £19 between the cheapest and the dearest product on the same dates, and the operator you pick matters far less than the type of parking you pick. That is the single most useful thing to understand about Heathrow pricing before comparing any two quotes.

Is One Stop Parking the cheapest option?

A comparison that never returns an unfavourable answer is not a comparison, so this one is run on the numbers rather than on the commercial relationship. The whole Heathrow field, priced side by side, is on the Heathrow Airport parking discount code page.

What we have verified, and what we have not

Sold as on-airport parking covering all four operating Heathrow terminals — parking on the airport itself rather than a site you shuttle in from.

Against that, here is what we have not been able to confirm for One Stop Parking, and which we will not state as fact until we have:

• Which car park the booking actually lands in
• Walk or shuttle to each terminal
• Whether you keep your keys

The alternative is to guess, and a guess printed as a fact about a real business is not something we are willing to publish. If you have booked with One Stop Parking recently and any of the above is wrong or missing, the contact page reaches a person.

Getting to Heathrow

Typical drive times are 45 minutes from central London, 30 from Reading and an hour from Guildford. The M25 between Junctions 12 and 15 is the reliable delay.

Put the car park's own postcode in the satnav. Airport postcodes route to terminals, and a terminal at Heathrow is exactly where an off-airport booking does not want you. Being dropped off is not free here: Heathrow charges £6 for up to 10 minutes at every terminal, charged automatically by number plate. The UK drop-off charges guide lists every airport's tariff.
