The short version
There's no direct train or Tube between Gatwick and Heathrow — rail goes via central London and takes hours. The two real options are the National Express coach (direct, from ~£14.70, ~1 hour or a little more) and a private transfer (~1 hour terminal to terminal, fixed fare, flight tracked). For a tight connection, lots of luggage or a group, the car's certainty usually wins. If you're connecting between flights, leave a generous buffer — commonly around 3 hours minimum.
Switching between London's two biggest airports looks like it should be simple. It isn't, by rail — so most people choose between the direct coach and a private car. This page lays out both honestly, plus the connection times to protect if you're catching an onward flight.
Why there's no direct train
Despite both being major airports, Gatwick and Heathrow have no direct rail or Underground link. Every train route runs into central London and back out again — typically a change (or two), 1.5 to 3 hours, and a fare far higher than the coach. Dragging cases across London by Tube to save nothing is the trap to avoid here. By road the two airports are about 45 miles apart, mostly via the M25, so the sensible choices are both road-based: coach or car.
The journey at a glance
- Distance: ~45 miles, mainly on the M25.
- Time: ~1 hour terminal to terminal in good conditions — but the M25 is unpredictable, so allow extra at peak times.
- Direction: both ways — Gatwick → Heathrow and Heathrow → Gatwick.
- Terminals: any Gatwick terminal to any Heathrow terminal (T2, 3, 4, 5) and vice versa.
- Price: one fixed fare for the whole vehicle, agreed up front.
Transfer vs coach
Indicative figures — coach fares vary by demand and how far ahead you book. Always check live before travelling.
| Option | Time | From | Best for |
|---|---|---|---|
| Private transfer (RushXO) | ~1 hour | fixed fare | Tight connections, groups, luggage, no waiting |
| National Express coach | ~1 hour–1h15 | from ~£14.70 per seat | Lowest cost, frequent, terminal-to-terminal |
| Train via London | ~1.5–3h | ~£35+ | Rarely worth it for this route |
The coach is genuinely good value and frequent — up to 60-plus services a day, picking up right outside the terminals. Its trade-offs are a scheduled departure (you travel when it leaves, not when you land), set luggage limits, and a fixed route. A private transfer leaves on your timing, tracks your flight, carries what fits the vehicle, and is one fixed price for the car rather than a ticket each — which adds up fast for a group.
Connection times to allow
A flight-tracked private transfer helps here: there's no scheduled coach to miss, the driver follows your inbound flight and is ready when you clear, and you go straight from one terminal to the other without a waiting-room in between.
When the car is the better call
- Tight or same-day connections: no fixed coach time to catch — you leave when you're through.
- Groups: one fixed fare for the vehicle usually beats several coach seats.
- Lots of luggage: no per-passenger case limits to worry about; loaded for you.
- Late or early flights: covered to your landing time, flight tracked.
- Families or accessibility needs: door to door, terminal to terminal, no transfers.
- Peace of mind: a single agreed price and a driver waiting beats stops, schedules and M25 stress.
