Yes you can take your rental car on a ferry to any of the Scottish islands. There is no extra cost.
When booking ferries, it is not possible to provide the rental car registration number (the plate) in advance. Ferry companies know this. The two main companies in Scotland are Calmac and Northlink ferries. Here is what to do to confirm bookings –
When booking a car on Calmac, they will ask:-
1) Are you towing any vehicles? – The answer is NO
2) Does this vehicle have a bike rack? – The answer is NO
3) Is this vehicle UK registered? – The answer is YES
Then you will be asked – “Please add details for this vehicle”
Scroll down and tick/check the box beside “!Select this box if you don’t know the details of the vehicle you will be travelling in. Please add your best estimation…”
In the length, width and height boxes, for all vehicle groups (except the Group 9 vans), enter 5 metres length, 1.9 metres width and 1.8 metres height.
For Group 9 vans, enter 6 metres length, 2 metres height and 2 metres width.
These figures should ensure the space allocated will ALWAYS be big enough for your vehicle. It will also ensure your car is charged at the lowest rate.
When booking on Northlink, you will be asked –
The number of passengers
Clicking on “Vehicles” will bring up a small pop-up screen.-
Enter 1 beside “Add vehicles and bicycles”
Choose “CAR in the select a vehicle box, then tick/check the box beside “Rental car/Unknown license plate”
That is it. The system will allocate a space up to 2,2 metres high and no cars on our fleet are that high. Nothing else needs to be entered.
