Yes, Anytime return tickets are generally refundable, but new regulations introduced in April 2026 have added specific conditions. For tickets purchased before April 1, 2026, you can usually claim a refund up to 28 days after the ticket's expiry for any reason, though a small administrative fee (around £5) may apply. However, under the updated rules for tickets bought after this date, "walk-up" tickets like Anytime returns must be cancelled or refunded by 23:59 the day before they become valid for travel to receive a full refund. If the ticket is already valid, a refund is typically only granted if the train service was delayed or cancelled, or if you can prove exceptional circumstances prevented your journey. Always check with the specific train operating company for their current fee structure.
