Advance tickets (which are valid on a specific train only) for travel up to 31 December 2021 can have their date and time changed for free up until 6pm the day before. If the price of your new ticket is more expensive, you'll need to pay the difference. You can still change your ticket at any time before you travel, but there will be an admin fee of £10.
If you don’t know when your new journey will be, you can ask for a travel voucher instead. This will be valid for 12 months.
Off-Peak and Anytime tickets can also be changed free from admin fees, up to the date of departure.
How to change your ticket
Tickets bought on GWR.com or the GWR mobile app
You can change your ticket when logged in to your account.
If your journey is more than five days away, we’ll send your new ticket to you – postal fees apply. Otherwise you’ll need to visit a staffed ticket office to change your ticket.
You can change an Advance ticket to another Advance ticket, or to a more flexible Anytime, Off-Peak, or Super Off-Peak ticket. The origin, destination and train company or route shown on the ticket must remain the same.
If you have Advance tickets for your outward and return journey and need to change one or both, you may find that an Off-Peak Return fare is cheaper. You will need to pay the difference in price between the cost of the new ticket and the fare already paid. We charge a £10 admin fee for each ticket.
