Luxembourg to London by train or plane: Eurostar via Brussels or Paris

London is about six hours from Luxembourg by train — one change in Brussels or Paris onto the Eurostar. Here is how both routes work, how much they cost, the border checks to allow for, and when flying makes more sense.

Via Brussels: the everyday route

Take the hourly Belgian InterCity to Brussels-Midi (€21.30 in 2nd class, valid on any train that day — see Luxembourg to Brussels and Belgium), then the Eurostar to London St Pancras in two hours. Eurostar fares work like airfares — the earliest advance fares start around £51 one way. Booking opens up to 11 months ahead. Rail Europe and Trainline can sell the whole journey in one booking; or book the Eurostar on eurostar.com and the Brussels ticket on b-europe.com.

Check-in and border checks: Eurostar closes check-in 30 minutes before departure in London and asks for at least 45 minutes in Brussels, because passport and security checks happen before you board. On the way to London, allow a comfortable margin in Brussels after the InterCity arrives. Non-EU travellers are registered in the EU’s Entry/Exit System when entering Schengen — see Entering Luxembourg: Schengen, EES and ETIAS.

Via Paris

Take the TGV to Paris Gare de l’Est (about 2h10, Luxembourg to Paris by train), walk about seven minutes to Gare du Nord, and take the Eurostar to London (about 2h20). There are fewer TGVs than InterCities, and both trains are reservation-only, so allow at least 60 minutes in Paris outbound and 90 on the way back. The advantage: a stop in Paris.

Flying instead

Flights between Luxembourg and London are short and frequent; check which London airport you arrive at and how long the trip into the city takes. Luxair also added Edinburgh to its network in 2026. From Luxembourg Airport the tram and buses to the city are free — Luxembourg Airport to the city centre.

Luxembourgish for the trip

A few sentences from the official dictionary, each with its native recording — the kind you will use on the platform and on the bus. More in Luxembourgish on the bus and the train.
