In reply to Flinticus:
I don't think you are going about this the right way.
Any suggestion we give will be most likely irrelevant as they may not insure you for a reasonable premium.
There doesn't seem to be any logic to why one big brand company may insure you for £700 and another want £5000 for the same level of cover.
Better to do a comparison, take the cheapest five, publish their names and level of cover they're offering and see what feedback you get and go from there.
My most recent was with 1st Central. They were fine. Replaced my windscreen with no push back. So I would recommend, but they tried to double my renewal so I went elsewhere.
