Heathrow to Cambridge is about 40 miles. A pre-booked fixed-price taxi typically costs £125 to £160 and takes 50 to 70 minutes door to door. The cheapest option is the National Express coach, which starts from around £14.70 one way, and the train works out roughly in between on price but needs a change in central London. Checked 2026.
Taxi: cost and journey time
Several fixed-price operators quote £125 to £160 for a standard saloon on the roughly 40-mile run from Heathrow to Cambridge, with a typical journey time of 50 to 70 minutes depending on traffic on the M25 and M11. This is the only door-to-door option of the three, which matters if you're travelling with a lot of luggage, arriving very early or late, or heading somewhere in Cambridge that isn't a short walk from the rail or coach station. Treat any quote as indicative until you've confirmed it with your chosen operator, and always get the price fixed in writing before you travel. See the full routes and fares table.
Coach: the cheapest option
National Express runs a direct coach between Heathrow and Cambridge, with fares starting from around £14.70 one way when booked ahead (prices rise closer to the travel date and with less availability). It's the most budget-friendly way to make the journey without a car, though as with most inter-city coach routes it isn't as frequent as the train, so check the timetable against your landing time, particularly for an evening arrival.
Train: faster than the coach, but needs a change
There's no single direct train from Heathrow to Cambridge. The practical route is the Elizabeth line or the Piccadilly line into central London, then a change onto a Cambridge service, commonly from King's Cross. Once you add the Underground or Elizabeth line leg, the change, and the roughly 50-minute run up to Cambridge, the door-to-station journey typically comes to around 2 hours, sometimes a little more depending on connections. Fares for the whole trip commonly run somewhere in the £30 to £60 range depending on how far ahead you book and which ticket type you choose; check the exact fare on National Rail before you travel, since advance tickets on the Cambridge leg can bring this down.

Booking tips for this route
Confirm whether your taxi quote is a fixed price or a metered fare before you book, since a metered fare on a run of this length can move more with M25 traffic than a short hop into central London. Ask whether the operator tracks your flight number, so a delay doesn't turn into a missed pickup or an extra charge. If you're a group or carrying a lot of luggage, check the vehicle size when you book, since a standard saloon may not comfortably fit four passengers and full-size cases on a trip this length. For the return journey from Cambridge to Heathrow, the same three options apply in reverse, so book your taxi with a sensible margin before an early departure, or check the last workable coach or train connection if you're travelling by public transport.
Which to choose
For a group, heavy luggage, or a flight landing outside normal daytime hours, a pre-booked fixed-price taxi removes the risk of missing a coach or a tight rail connection, even at the higher cost. If you're travelling light and want the lowest price, the direct coach is the clear value pick, provided the timetable lines up with your flight. If you'd rather not wait for the next coach and don't mind one change in central London, the train is often quicker and more frequent through the day.
