Belgium follows the standard Schengen rules: a passport issued within the last 10 years and valid at least 3 months after your planned departure from the Schengen area, with short stays visa-free for UK citizens within the 90-days-in-180 limit.
At the border
Belgian entry checks happen at St Pancras before boarding, including EES biometric registration — on arrival at Brussels-Midi or, from December 2026, Antwerpen-Centraal, you walk straight off the train.
The Antwerp quirk
The new direct London–Antwerp service is direct outbound only. Antwerpen-Centraal has no UK border facilities, so the journey home is sold as one combined SNCB + Eurostar ticket with a change at Brussels-Midi, where passport and security checks for the UK take place. Build that into your return timing.
Every Eurostar journey starts with reaching the station on time. Rushxo runs fixed-fare private hire across London and the UK, 24/7 — the quote is the fare, with no surge for early starts or late arrivals. Book a St Pancras transfer, WhatsApp us, or call 020 8888 9988.
