Quick answer
Heathrow to Cambridge is a longer trip than most Heathrow transfers — around 70 miles by road via the M25 and M11, typically 1.5-2 hours by car depending on traffic, longer at peak times. There's a direct National Express coach service that avoids the need to cross central London, taking roughly 2 hours 15 minutes to 2 hours 25 minutes. A pre-booked taxi is the most direct door-to-door option but isn't part of Heathrow Airport Guide's standard published route-price table, so always get a fixed quote before you travel rather than assuming a fare.
By road: taxi or pre-booked minicab
Cambridge isn't one of the standard routes listed on our routes page alongside destinations like Windsor, Reading or Oxford, largely because it's a longer, less frequently requested journey. That doesn't mean it isn't possible — it just means you should treat it as a bespoke, longer-distance transfer rather than a fixed "list price" route.
- Metered black cab: available from the marshalled rank outside any terminal's arrivals hall, no booking needed — but for a ~70-mile trip, the meter will run for the full journey, so costs can add up and are harder to predict in advance.
- Pre-booked minicab: the more common choice for a trip this length, since you agree the price before you travel. Heathrow Airport Guide's recommended pre-booked operator is 247 UK Airport Taxi, part of the Tick Taxi group (the group's Bristol arm holds a 5.0 Google rating and the 2026 QSI Gold Award) — flagged here as our affiliated recommendation rather than an independent comparison. Get a written, fixed quote for the Cambridge run specifically, since it's outside the typical short-hop pricing.
See the taxis page for how ranks and pre-booking work at each terminal, and our guide on booking a taxi to Heathrow for what to check before you commit to a longer-distance fare.
By direct coach (National Express)
National Express runs a direct coach service between Heathrow and Cambridge, which is genuinely useful here because it avoids routing through central London. Coaches depart from the Heathrow Central Bus Station (serving Terminals 2 and 3) with several journeys a day, and arrive at Cambridge Parkside bus station, close to the city centre.
Journey time is typically in the region of 2 hours 15 minutes to 2 hours 25 minutes, and one-way fares can start from around the mid-teens in pounds for advance bookings, rising depending on how close to travel you book. These figures move with National Express's own pricing and timetable, so check nationalexpress.com for the live schedule and fare before you travel.
This is often the most straightforward option if you're travelling solo or in a small group without heavy luggage and don't need door-to-door drop-off.
By train
There's no direct rail line between Heathrow and Cambridge. The rail option means travelling into central London first — via the Elizabeth line or Heathrow Express — then crossing to King's Cross for a train up to Cambridge (around 45-60 minutes from King's Cross on the fastest services). Once you add the cross-London leg and connection time, this route is usually slower and more hassle than the direct coach, so it's generally only worth considering if you have a specific reason to break your journey in London. See our public transport page for details on the Elizabeth line and Heathrow Express from each terminal.
Which option makes sense?
- Avoiding central London entirely, solo or small group, light luggage: the direct National Express coach
- Door-to-door, or travelling with family/luggage/at odd hours: a pre-booked minicab with a fixed quote
- Already planning to stop in London anyway: rail via King's Cross
- No booking made and happy to pay a running meter for a longer trip: a black cab from the rank, though this is the least common choice for this particular route
Whichever you choose, build in extra time — this is one of the longer transfers out of Heathrow, and traffic on the M25 in particular can add significantly to a road journey.
FAQs
How far is Heathrow from Cambridge?
Around 70 miles by road, using the M25 and M11. Drive time is typically 1.5-2 hours depending on traffic, and can be longer at peak times.
Is there a direct coach from Heathrow to Cambridge?
Yes — National Express runs a direct service between Heathrow (Terminals 2 and 3) and Cambridge Parkside bus station, avoiding the need to route through central London. Check nationalexpress.com for current times and fares.
How long does the coach take?
Typically around 2 hours 15 minutes to 2 hours 25 minutes, though this varies by specific departure and traffic conditions — check the live timetable before booking.
Can I get a train directly from Heathrow to Cambridge?
No direct line exists. You'd travel into central London (Elizabeth line or Heathrow Express) and then take a separate train from King's Cross, which usually makes the coach the more practical single-ticket option.
How much does a taxi from Heathrow to Cambridge cost?
Cambridge isn't part of our standard route-price table because it's a longer, less common transfer. Always get a specific, fixed quote from your operator before booking rather than assuming a price, and expect it to be higher than shorter routes like Windsor or Reading given the extra distance.
Is it better to pre-book a taxi or take a black cab from the rank for this route?
For a ~70-mile trip, most travellers pre-book a fixed-price minicab rather than take a metered black cab, simply because the fare is agreed upfront rather than accumulating over a longer journey.
