It is not possible to make any changes to an Off-Peak, Super Off-Peak or Anytime UK rail ticket. Where possible, these bookings can simply be cancelled and a new ticket purchased for the desired route, time or date. You can cancel your ticket by completing the refund application by clicking here.
In the case of an Advance fare ticket, you will first need to make a replacement booking for the same route, selecting a different date or time. You will then need to complete the refund application by clicking here.
