The quickest public transport route from Heathrow to Eton College is the Elizabeth line to Slough, about 20 minutes, then a Great Western Railway shuttle to Windsor & Eton Central, a further 7-10 minutes, followed by a 10-20 minute walk across the Thames into Eton. A direct coach, the Flightline 703, takes 52-65 minutes with no change. A pre-booked taxi or private hire car typically costs around £35-£45. Checked 2026.

By train, via Slough
The fastest rail route is the Elizabeth line from Heathrow to Slough, taking about 20 minutes, then changing onto the Great Western Railway shuttle to Windsor & Eton Central, a short hop of 7-10 minutes. That's a total of roughly 30-35 minutes to the station. Fare-comparison sites put a single ticket at roughly £13-£20 depending on time of day and how far ahead you book; confirm the exact current fare on National Rail before you travel, since this isn't covered by Heathrow's own published fare list.
From Windsor & Eton Central, Eton College itself is a walk of about 15-20 minutes: across Windsor Bridge over the Thames and up Eton High Street. If your train instead calls at Windsor & Eton Riverside station (served from Waterloo rather than Heathrow, so less relevant for most airport arrivals), the walk from there is somewhat shorter, around 10-15 minutes.
By coach: the Flightline 703
The Flightline 703 (Windsor Express), operated by Thames Valley Buses, runs from Heathrow to Windsor in about 52-65 minutes with no need to change buses, making it the simplest single-journey option if you don't want to deal with a rail change at Slough. This is a long-distance coach service, so it isn't covered by the £3 national bus fare cap; confirm the current fare with Thames Valley Buses or Reading Buses before you travel. The coach sets you down in Windsor, from where the same 15-20 minute walk across Windsor Bridge applies.
By taxi or private hire
A pre-booked private hire car from Heathrow to Windsor typically costs around £35-£45, covering the journey by road in roughly 30-40 minutes depending on traffic, and this is the only option that can take you right to Eton College's gates rather than leaving you with a walk from the station or coach stop. You can also get an Uber or similar from Heathrow to Windsor, though not from the terminal forecourt itself; check the app for the designated pickup point at your terminal.
Why there's no single direct option
Eton sits just across the Thames from Windsor, and neither has a direct rail or coach link straight from Heathrow; every public transport route involves either a change (rail, via Slough) or a dedicated long-distance coach (the Flightline 703). A taxi is the only way to avoid both a change and a walk at the end.
Which should you choose?
- Choose the train via Slough if you want the fastest option to the station itself and don't mind a short walk into Eton at the end.
- Choose the Flightline 703 coach if you'd rather avoid changing at Slough, accepting a somewhat longer overall journey.
- Choose a taxi or private hire if you want to be dropped at Eton College directly, are carrying luggage, or are travelling with a group.
Visiting Windsor Castle at the same time
Many visitors combine a trip to Eton College with Windsor Castle, which sits a short walk from both Windsor stations on the opposite bank of the Thames. See our guide to Heathrow to Windsor and Legoland for the fuller breakdown of train, coach and taxi options covering Windsor itself, including Legoland transfers.
All prices and journey times here were checked against Thames Valley Buses' and National Rail's published routes, and existing operator listings, in 2026. Eton College has its own visiting arrangements and term-time access restrictions, so check its official visitor information before you plan a trip specifically to see the school itself.
