What to expect, and what to do if they say no

What to expect

  • Train companies usually pay within a few weeks once the claim is checked.

If they say no

  • Ask the train company to review a rejected claim.
  • Escalate to the Rail Ombudsman if it isn't resolved.

What happened when people tried it

  • We haven't verified a real-world example for this one yet, so it's a tool guide plus a prompt. Tried it? Tell us what happened (link below).

Why this works

The problem: Many eligible passengers never claim because they don't know about Delay Repay or which company to claim from.

How AI helps: AI can work out which train company to claim from, check eligibility from your journey details, and draft the claim.
