Found this,
Will I get a ‘no claims’ bonus at the end of my lease?
You will not get a no-claims bonus, because we own the vehicle.
If you leave the Scheme
Our insurance provider might give you a claims history letter to show any claims you or your other drivers have made.
You should be able to ask for this in your Motability Scheme online account, or you can call them on 0300 037 3737.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
