Thameslink Delay Repay: how much you get and how to claim

By Journey Radar Team · Last checked against official sources on

Thameslink pays Delay Repay when you reach your destination 15 minutes or more late, whether your train was delayed or cancelled. You get at least 25% of a single fare for 15-29 minutes, 50% for 30-59 minutes, 100% for 60-119 minutes and the whole return fare at 120 minutes or more. Claim within 28 days on Thameslink’s Delay Repay claim portal, or wait for a Key Smartcard auto claim to arrive and confirm it. The same rules cover Great Northern, which has its own Great Northern claim portal.

Thameslink and Great Northern are two brands of Govia Thameslink Railway (GTR), which also runs Southern and Gatwick Express. GTR moved into public ownership on 31 May 2026, but GOV.UK confirmed that tickets, timetables and the brand names stayed the same, and the Delay Repay pages carry on unchanged. Southern and Gatwick Express passengers have their own page: Southern Delay Repay.

You qualify if a Thameslink or Great Northern service got you to your destination at least 15 minutes after the timetabled arrival. Cancellations count too, as long as you went on to travel.

Every ticket type is covered: singles, returns, Advance tickets, season tickets, Flexi seasons, Key pay-as-you-go and contactless or Oyster journeys. GTR accepts a wide range of proof: the ticket itself, a receipt, a screenshot of your booking, the UTN on an e-ticket, your Key Smartcard number, or a TfL statement if you tapped in with contactless or Oyster. That is more generous than some neighbours; Southeastern, for example, does not accept receipts.

GTR states each band as a minimum (“at least”), so treat these as the floor.

Delay at destination Single ticket Return ticket, one leg late
15-29 min 25% of the single 12.5% of the return fare
30-59 min 50% of the single 25% of the return fare
60-119 min 100% of the single 50% of the return fare
120 min or more 100% of the single 100% of the return fare

A note on returns. GTR’s own page describes the return payout as a share of the affected portion (25% of the delayed leg, then 50%, then 100%). Other operators, such as Southeastern and Greater Anglia, describe it as a share of the whole return (12.5%, 25%, 50%). The two come to the same money, because one leg is half a return. Across Journey Radar we quote the whole-return figure, as in the table.

Worked example: say you hold a £30 return, with the evening leg 40 minutes late, pays 25% of £30, which is £7.50. If that leg had been 2 hours late, you would get the full £30 back.

Season tickets and Flexi seasons

GTR turns your season ticket into a value per journey, then applies the bands.

Season ticket Divide the price by
Weekly 10
Monthly 40
Quarterly 120
Six-monthly 240
Annual 464
Flexi Season 16

You then get 25%, 50% or 100% of one journey for the first three bands, and a full day’s travel (a return journey) at 120 minutes or more. For a Flexi Season, a 120-minute delay pays two single journeys. GTR caps season claims at one day’s travel and allows one 120-minute claim per day, and no claim can be worth more than the ticket cost.

Example: a £4,640 annual season works out at £10 per journey. A 35-minute delay pays £5; a 2-hour delay pays £20.

How to claim, step by step

If you use a Key Smartcard: Auto Delay Repay. GTR compares your tap-in and tap-out times with the timetable and with known train delays, including cancellations. When it spots a qualifying journey it creates a claim and emails it to you within 48 hours. This is not money paid without you lifting a finger: you have to open the email, press claim and confirm within 28 days. It works for every Key ticket type, including keyGo, on Thameslink, Great Northern, Southern and Gatwick Express trains. A few things break it:

  • You must tap in and out, even when the gates are open.
  • A journey that uses more than one ticket on your Key needs a manual claim.
  • If you submit a manual claim for the same journey, the auto claim is cancelled.

Everyone else: claim online.

  1. Open Thameslink’s Delay Repay claim portal (or the Great Northern portal for Great Northern trains).
  2. Enter the journey, the train you planned to catch and your arrival time.
  3. Upload proof of travel (ticket photo, receipt, e-ticket UTN, Key number or TfL statement).
  4. Pick a payment method and submit. You can bundle up to three travellers’ claims into one submission.

By post. GTR has a single paper form for all four of its brands, which is on the Thameslink Delay Repay page. Post it to Freepost RUHE-TXXU-GHHA, GTR, Derby DE1 9RQ.

How you get paid. Manual claims can be paid by bank transfer, e-voucher (you need an account), PayPal, cashable National Rail vouchers or a donation to Samaritans or Railway Children. Vouchers last 12 months and can be cashed at any ticket office run by a GTR brand. Auto claims pay by bank transfer, Visa card, e-voucher or PayPal, with no cheques or cashable vouchers. Amazon Pay is no longer offered.

How fast. GTR aims to reply within 20 working days and says it usually manages five. Thameslink’s published figures for 28 June to 25 July 2026 show 64,465 claims received, 57,963 approved and an average turnaround of 2.8 working days.

Split tickets, connections and other operators

GTR will only pay for a missed connection if you allowed enough time to change, including any cross-London transfer, and you held a through ticket. The claim goes to whichever operator caused the first delay. National Rail’s Conditions of Travel (condition 32.1) measure the delay at your final destination and let you send a claim to any operator you travelled with, which then passes it on.

GTR’s pages do not give a separate split-ticket method. Under condition 14.2, a combination of tickets is valid as long as the train stops at the station where one ticket ends and the next begins. Our Delay Repay guide explains how split tickets and multi-operator journeys are handled across the network.

Cancelled trains, strikes and engineering works

If your train is cancelled and you travel later, claim Delay Repay on how late you actually arrived. If you decide not to travel at all, that is a refund, not Delay Repay: you get your money back from wherever you bought the ticket, and you cannot claim both.

GTR’s pages do not set a separate rule for strike days, so the national position applies. National Rail says that if industrial action makes you late by enough to reach the Delay Repay threshold, you claim from the operator you travelled with. If your train is cancelled, delayed or rescheduled because of a strike, National Rail Conditions of Travel condition 30.1 gives you a fee-free refund or change from the retailer that sold you the ticket. See our train strikes page for current action.

For engineering works, condition 32.1 measures delays against the timetable that applies on the day, including any replacement timetable published in advance. A slower planned timetable is not a delay in itself.

If your claim is refused, or you lost more than the fare

Check the reason given, then go back to GTR with the missing evidence and your claim reference. If the delay cost you more than the fare, such as a missed flight or an extra taxi, GTR says you can take it to its customer relations team under the Consumer Rights Act, which requires a service to be provided with reasonable care and skill. National Rail’s Conditions of Travel (condition 32.2) add that you cannot be paid twice for the same loss. The Delay Repay hub covers escalation beyond the operator.

Frequently asked questions

Is Thameslink Delay Repay 15 or 30 minutes?

Thameslink pays from 15 minutes. If you reach your destination 15 to 29 minutes late you get at least a quarter of your single fare back, rising to the full single fare at 60 minutes and the full return fare at 120 minutes.

Does Thameslink pay Delay Repay automatically if I use a Key Smartcard?

Almost. Thameslink's Auto Delay Repay matches your Key taps against the timetable and emails you a ready-made claim within 48 hours. You still have to open it and confirm the claim within 28 days, otherwise nothing is paid.

I travelled on Great Northern. Do I claim on the Thameslink site?

Use Great Northern's own claim portal at delayrepay.greatnorthernrail.com. Both brands are run by GTR with the same rules and payout bands, so everything on this page applies to Great Northern journeys as well.

Can I claim Thameslink Delay Repay for a cancelled train?

Yes, if you still travelled. Thameslink's scheme covers cancellations as well as delays, and the payout is based on how late you reached your destination on the next train you could take. If you gave up and did not travel, ask for a refund instead.

How long does Thameslink take to pay Delay Repay?

GTR says it replies within 20 working days and usually within five. Its own published figures for 28 June to 25 July 2026 show an average of 2.8 working days on Thameslink claims.

Can I claim for my partner and children on one Thameslink claim?

Each traveller needs a separate claim, but you can put up to three claims into a single online submission, so a small group can be done in one go.

Can I claim Thameslink Delay Repay on contactless or Oyster?

Yes. Thameslink accepts a TfL journey statement as proof of travel for contactless and Oyster journeys. Auto Delay Repay only works on the Key Smartcard, so contactless and Oyster users claim manually.
