You may struggle as most insurance companies now will not give traders to anyone who does not have premmisses and is not registered as a company .
They have got wise to people getting a traders and running about 10 cars and 3 bikes on it
Also beware of those insurance companies in the auto traders etc offering cheap traders policies ,,they are road risk only , not worth the paper there written on if you ever have to claim .
My insurer comes round every year just before renewal and does a full risk assesment on my workshop etc , and asks details of all cars ( on the road ) i have to give reg numbers , list all name drivers etc , and also i have to update the MID insurers data base every time i get / buy another car
A lot of hassle ,BUT i am well covered .
BLOODY EXPENSIVE THO
