National Express run a high frequency service over 100 times a day
between Heathrow Airport and Gatwick Airport (North & South Terminals). Very
popular as a transfer option as there is no competing rail service.
The route taken is via the M25 which means there's some good and there's some
bad. The good news is that when the route is clear it means the airports are
linked by motorway without needing a journey through central London and its
almost a non-stop journey. The bad news is that the M25 has a reputation for
being one of the most congested motorways in the UK with seemingly never ending
roadwork's on one section or another. So this can leading to a wide variance
from advertised travel times. However something to note is that congestion is
more normally limited to working hours on weekdays between 8am and 6pm. It will
also vary greatly depending on your direction of travel. The National Express
coach from Heathrow to Gatwick via the M25 is an anti-clockwise journey while
the Gatwick to Heathrow leg is a clockwise journey. This is important to note
because congestion is heaviest in an anti-clockwise direction in the evening
(3pm to around 7pm) and in a clockwise direction in the morning (7am to 11am).
National Express to Gatwick operates from all 4 terminals and both Gatwick
terminals in the opposite direction. This means for Heathrow terminals 2 and 3you must make your way to the central bus station. Reckon on a 10 minute walk
using the underpass under each terminal and clearly signposted.
All coaches have an onboard WC and the 200 and 201 have NXTV.
Service operates close to 24 hours a day (02.30 till 00.30). The service from
terminal 4 is less frequent than from the central bus station and terminal 5
(part of the same route), up to every hour compared to ever 20 minutes from the
central bus station (terminals 1,3 and 5). You can use the Heathrow express to
get from terminal 4 to Heathrow terminals 2 and 3for free and it takes just a
few minutes.
