Is Caledonian Sleeper legit?
LegitYes, Caledonian Sleeper is a real overnight train between London and Scotland, but a good night's sleep on board is not guaranteed. Heating that will not settle, a noisy carriage or a late arrival can turn a pricey room into a long night, and Delay Repay only starts at 30 minutes late.
What we checked
- Scottish Government owned since 2023
- Run by Caledonian Sleeper Limited
- Registered office in Inverness
- Ratings on other review websites: 4/5
Watch out for
- A booking made through another retailer, where Delay Repay is not automatic and the form must go in within 28 days.
- A return bought direct, which is sold as two singles, so a delay on one leg pays back only that leg.
- A change of travel date, which means cancelling and rebooking, with up to £10 per ticket kept as a fee.

How do I contact Caledonian Sleeper?
The Caledonian Sleeper contact number is 0330 060 0500, and the email address is enquiry@sleeper.scot; there is also a contact form and a live chat on the Caledonian Sleeper website. Have your CSW or CST booking reference, the date of travel, your route and your room or seat type ready. Changes to a booking go through Amend My Booking on the website rather than the Guest Service Centre.
Refund smaller than you expected, or a room not as booked? Start your complaint here as well, and we take it to Caledonian Sleeper by email, social media and printed letters.
Can I get compensation if my Caledonian Sleeper train is delayed?
Yes: Caledonian Sleeper takes part in the national Delay Repay scheme, and the delay is measured by the time your train reaches your destination against the published timetable. If you booked on the Caledonian Sleeper website or through its Guest Service Centre, Automatic Delay Repay starts the claim for you and emails you to confirm your journey; click that link within the time limit, or the claim lapses. If you booked through a third party, claim through the contact form on the Caledonian Sleeper website with Delay Repay as the subject.
Delay Repay claim declined by Caledonian Sleeper? Bring it through our complaint process: our trained AI opens a case for you and keeps coaching you on what to reply next.
How do I cancel a Caledonian Sleeper booking and get a refund?
To cancel a Caledonian Sleeper booking, use Amend My Booking on the website or, close to departure, the live chat, and apply for the refund in My Account or through the contact form with your CSW or CST booking reference. Caledonian Sleeper refunds on a sliding scale, the full fare well ahead of travel and part of it closer to departure, with no refund after a cut-off the day before travel, so check the current refund conditions before you cancel. Refunds go back to the card you paid with, and tickets bought at a station or from another retailer are refunded by whoever sold them.
If unplanned disruption hits your departure day and you decide not to travel, Caledonian Sleeper says you are eligible for a refund.
Can I take a Caledonian Sleeper complaint to the Rail Ombudsman?
Yes: the Rail Ombudsman investigates unresolved complaints about train operators in Great Britain that take part in its scheme, and Caledonian Sleeper is on its list of service providers. The Rail Ombudsman generally expects Caledonian Sleeper to have had the chance to put things right first, so keep a record of every email, chat, call and booking reference.
