as said probably not worth it as excess would probably be more, if you do want a quote then try your own insurance 1st as an add on, or try stephen ayre at G.T.Insurance, he is very helpful, his number is 0115 9394747, we have started going to him now as helpful and competetive, all our vans are with steve, if you have insurance its probably cheaper to add on than start a new policy, if you try both it will give you an idea f which is best,
