How do I reserve a seat on Lumo?

When you book onto a Lumo train, you receive a seat reservation automatically. However, you can still find a seat for your journey if you join a Lumo service without a reservation. Look out for the green lights above the seats, which indicate that they are not reserved.



Reserving a seat on Lumo is a straightforward digital process, as seat reservations are mandatory for their high-speed services between London King's Cross and Edinburgh. When you book your ticket directly through the Lumo website or mobile app, a seat is automatically assigned based on the preferences you select during the booking flow. If you purchase your ticket via a third-party retailer (like Trainline), a seat will still be allocated, but you may not have the same level of choice. In 2026, Lumo does not allow seat changes after a purchase is completed through their "seat picker" tool, so it is vital to get it right the first time. For those traveling with flexible tickets like "LumoAny," you can board different trains, but you must look for seats with a green light above them, which indicates the seat is unreserved and available for "walk-on" passengers.

Railsmartr says: So, which is cheaper, LNER or Lumo? In most cases, we would say Lumo will have the edge when you're travelling alone. If you're travelling last-minute, you might snap up a great deal on quieter trains. However, busier trains might have little or no difference – it might even be cheaper to pick LNER.
