Heathrow Airport sits administratively inside the London Borough of Hillingdon — not Hounslow, despite what the postal address suggests. So you might expect the Tube to be the obvious way between them. It isn’t.
The Piccadilly line splits into two branches at Acton Town: one to Heathrow, one to Uxbridge. Hillingdon station sits on the Uxbridge branch.
So a Tube journey means travelling away from the airport first. Then you change trains, and come back out the other way. That’s a lot of effort for a trip that’s only 4 miles by road.
Taxi, bus or Tube: the quick comparison
| Option | Journey time | Frequency | Typical cost |
|---|---|---|---|
| Fixed-price taxi | ~12 min, door to door | Booked in advance | One fixed price, up to 4 passengers |
| Direct bus (e.g. the 278) | 10–20 min | Every 15–30 min | Flat single fare per person |
| Piccadilly line (Tube) | 50–65+ min, one change | Every 10–20 min per leg | ~£3–£6 per person |
Bus and Tube fares are approximate TfL pay-as-you-go figures. They change with time of day, so check current prices before you travel. Taxi journey time is drive time only — your fixed price is confirmed at booking.
Why the Tube is the wrong call here
Westbound Piccadilly trains divide at Acton Town, with half continuing to Heathrow and half branching to Uxbridge. Because Hillingdon sits on that second branch, there’s no direct service. You’d ride away from the airport, change at Acton Town, then travel back out on a different line.
Where the taxi and bus actually win
Once you rule out the Tube, this becomes a simple choice. A taxi is priced per car and gets you door to door in around 12 minutes. Because your driver tracks your flight, a delay costs you nothing extra.
The bus is cheaper per person and reasonably quick for a solo traveller. But it’s still a fixed route with a walk at each end.
For a family, a group, or anyone with luggage, the taxi is the clear win. For a solo traveller near a direct bus stop with no bags to speak of, the bus is a fair budget option.
So what should you actually book?
Travelling with a family, a group, or heavy luggage? A fixed-price taxi gets you there in around 12 minutes for one price.
Solo, light, and near a direct bus route? The bus is a reasonable, cheaper option.
Thinking about the Tube because it “should” be close? Don’t. The branch split at Acton Town makes it the slowest option by far.
Heathrow’s postal address actually points to Hounslow, next door — where, unlike here, the Tube is genuinely the quick option.

How much is a taxi from Heathrow to Hillingdon?
Hillingdon is closer to Heathrow than Uxbridge, which sits at our local minimum fare of around £49 to £57. So expect a Hillingdon transfer to sit at or near the low end of that range. Use the booking form for your exact fixed price.
Why does the Tube take so long between Heathrow and Hillingdon?
The Piccadilly line splits into a Heathrow branch and an Uxbridge branch at Acton Town, and Hillingdon sits on the Uxbridge side. So there’s no direct train — you travel away from the airport, then change at Acton Town. That round trip can take over an hour for a journey that’s only 4 miles by road.
Is there a faster public transport option than the Tube?
Slightly. The 278 bus to Hayes & Harlington, then a short train, takes around 54 minutes. That’s quicker than the Tube’s hour-plus, but still far behind a direct taxi at 12 minutes.
What’s the fastest way from Heathrow to Hillingdon?
A fixed-price taxi is the fastest option by a wide margin, covering the trip door to door in around 12 minutes. But a direct bus is a reasonable option for a solo traveller without luggage.
Is Heathrow really in the London Borough of Hillingdon?
Yes — Heathrow sits administratively within the London Borough of Hillingdon. Its postal address uses Hounslow as the post town, which causes the confusion. But the airport itself sits inside Hillingdon’s boundary.
Is a taxi worth it for such a short distance?
Given the Tube isn’t a practical option here, yes. For families, groups, or luggage, the taxi is the clear choice. A solo traveller without bags could reasonably take the bus instead.
