Whether a "split save" ticket (splitting a long journey into multiple smaller tickets to save money) is refundable depends entirely on the terms and conditions of the individual tickets purchased. Usually, split tickets consist of several "Advance" tickets, which are notoriously non-refundable unless the train operator cancels the service. If you purchased "Off-Peak" or "Anytime" tickets as part of your split, those specific portions are generally refundable, minus an administrative fee (typically around £5 to £10). In 2026, UK rail providers and third-party apps like Split My Fare allow you to claim a refund on the unused portion of a flexible ticket, but the "booking fee" or "split saving fee" charged by the app is almost never returned. If one train in your split journey is delayed, causing you to miss the next one, the "National Rail Conditions of Travel" protect you, and you can usually take the next available train even if your split tickets were non-refundable.
