Other people will not be covered by Marshmallow to drive the vehicle, unless they are a named driver on your policy. You can add a driver to a car policy, but adding one to a van policy is not possible.
How can I add a named/additional driver to my policy?
If you'd like additional drivers to have fully comprehensive insurance when driving your car, you can add them to your Marshmallow policy.
You can add a driver quickly and easily through the app. From the home screen:
Tap your policy
At the top of the screen, tap Update details
Scroll down to Additional Drivers
Tap Edit
Follow the instructions on screen to add a driver to your policy.
Please note: Additional drivers can only be added to car policies and not to van policies.
Key things to note:
Some car insurance companies will cover their drivers on other cars. Usually, that means they would have a basic third party cover, so it would be legal for them to drive your car.
However, please be aware that this type of insurance is only valid if there is a primary cover on your car, and doesn't include any damages to the vehicle. So if the driver was at fault in an accident, you'd have to pay for the car to be replaced/repaired.
