The the level of cover and detailed terms & conditions in the policy booklet meet your specific needs then I can't see why not.
Try chrome insurance. I got very good deal with them recently for house insurance. They are brokers.
I'd avoid Chrome. I've seen them offer a client cover with Zurich on their own house with no accidental damage. For what it costs something like that isnt worth. That's direct insurer tactics - where they offer it as an extra cover and not brokers.
