Caledonian Sleeper Dog Policy in 2026: The £30 Fee, the Rules, and Where Dogs Cannot Go

*Last updated: August 2026.*

What the Policy Actually Says

Here is the good news, and it is better than most travellers expect: the Caledonian Sleeper lets your dog travel in your room, with you, through the night. This is not a train that consigns pets to a guard's van or a separate carriage. A private cabin with your dog curled on the floor beside the bed is precisely what the operator offers, and it is one of the reasons the Sleeper has quietly become the night train of choice for people who refuse to leave a dog behind.

The operator can accommodate up to two domestic pets in a room, and the conditions attached are straightforward once you know them. This guide covers what the £30 charge buys, how to add a pet to your booking, and the handful of restrictions that are worth committing to memory before you travel.

The £30 Charge, and What It Covers

A charge of **£30 per journey** applies when you travel with pets on the Caledonian Sleeper. Crucially, this is charged per journey, not per animal: whether you bring one dog or two, the fee for that journey is the same £30. What it covers is the cost of a deep clean of the cabin afterwards — the practical reason the operator can keep rooms available to the next guest, allergy-conscious or otherwise.

The distinction between per-journey and per-pet matters, because some passengers assume the fee scales with the number of dogs. It does not. One dog or two, the same £30 applies to the room for that leg. What it does apply to is each direction of travel. A return trip is two journeys, so a London to Inverness return with your dog will incur the charge twice — £60 across both legs.

How to Add a Pet to Your Booking

There is no separate registration form and no obscure telephone process to navigate. When you make your booking, you simply add the number of pets in the booking widget, and the system adds the £30 to your total automatically. That is the whole mechanism.

The one thing worth doing early is booking at all. Because only a limited number of rooms run on each night's train, and because each room can take a maximum of two pets, dog-friendly space is finite and the most popular nights fill well ahead. If travelling with your dog is non-negotiable, treat the pet booking as another reason to reserve the moment the window opens rather than a detail to sort out later. If your plans are unusual, or you are travelling with an assistance dog and want to confirm arrangements, the operator's guest services team can talk it through before you book.

Where Dogs Are Not Permitted

Your dog is welcome in your room, but not everywhere on the train, and the boundaries are firm.

The **Seated Coach** is off-limits to pets. If you are travelling with a dog, you need a private room; you cannot bring an animal into the reclining-seat accommodation. This is worth underlining because it means the cheapest way to travel is not open to you if a dog is coming along — a room is effectively mandatory, and that should factor into your budgeting from the outset.

The **Club Car**, the lounge and dining carriage, is likewise closed to pets. If you want to enjoy a dram or a meal in the Club Car during the journey, your dog must be settled in your room first; dogs cannot accompany you into the social heart of the train. Nor may pets be walked through to any coach other than the one where your room is booked — your dog's world for the night is your cabin and the corridor to it, no further.

One more rule surprises people: pets are not permitted on the beds. Your dog travels on the floor of the cabin, not on the berth, so it is worth bringing a familiar blanket or travel mat to make the floor space feel like home.

Guide dogs and registered assistance dogs are treated differently and generously: they may accompany their owners throughout the train, and the £30 charge does not apply to them.

Living With the Journey: Practical Realities

Two facts shape the overnight experience with a dog more than any rule. The first is that once you have boarded, you and your dog cannot leave the train until you reach your destination — there are no comfort stops, and the platforms en route are not an option. Plan your dog's toilet routine around a long, unbroken run; the London to Inverness service takes in the region of twelve hours, so a final walk immediately before boarding and a very early one on arrival are essential.

The second is that the staff are set up to help. Ask a host and they will bring water for your dog, and the operator's partnership with a Scottish natural pet-food brand means four-legged guests are often welcomed with a complimentary bag of treats — a small touch, but a telling one about how seriously the Sleeper takes canine passengers. Dogs are also welcome in the Caledonian Sleeper Guest Lounges at the major stations, provided they stay on a lead and off the furniture, which makes the wait before a late departure considerably easier.

A note on disruption: if a service is cancelled and replaced by a road service, the operator cannot guarantee your dog will be able to travel on the replacement. It is an uncommon scenario, but if your dog absolutely must reach the destination with you, it is worth having a contingency in mind.

The Honest Assessment

Whether the overnight works for your dog is a question only you can answer. A dog that settles easily in new surroundings, that has had a long walk and a light meal beforehand, and that is content to sleep at your feet will very likely take the whole thing in its stride and wake up in the Highlands as unbothered as you do. A dog that is anxious in confined spaces, or that cannot settle without pacing, will find twelve hours in a cabin harder — and so will you. Assess your own dog's temperament honestly, because the cabin is comfortable but it is not large, and there is no stepping out for air.

The policy, in the end, is refreshingly humane: your dog is not cargo, it is a guest. Prepare for the long run, book early, keep to the room, and the Caledonian Sleeper is about as good as travelling overnight with a dog gets in Britain.
