Gatwick Express services are scheduled to depart every 15 minutes between around 5am and midnight. There is a 3 hour gap in service in the early hours of each morning but the full frequency is running by 5am. The short shoulder hours at the start and end of the day frequency reduces to around twice hourly.

As of March 2026, the Gatwick Express—the non-stop rail link between London Victoria and Gatwick Airport—operates on a nearly 24-hour schedule to accommodate international flight times. The service typically starts around 5:00 AM and runs until approximately 12:30 AM (midnight). During peak hours, trains depart every 15 to 30 minutes, providing a consistent 30-minute journey time. On Sundays or during scheduled engineering works (such as the major track upgrades seen in early February 2026), the schedule may be modified, with some services replaced by buses or diverted to London Bridge via the Southern or Thameslink lines. While the Gatwick Express itself has a "finish" time around midnight, the airport station remains open 24/7 because other rail operators like Thameslink provide hourly "all-night" services to central London. Travelers are always advised to check the "Live Departures" on the official Gatwick Express app or website before their trip, especially for early morning or late-night flights, to ensure they aren't caught by the brief overnight window when the dedicated "Express" trains are undergoing maintenance.
