Sorry! it's not much help but you only know if you've got a good insurance company when you need them, if you have an accident and they don't try and get out of paying you or don't put as many hurdles in the way as possible for you too jump before you get paid out
.
Unfortunately you wont know how good they are until you need too claim (they're all good / helpful when you're paying your premium
), by then it's too late if you have a bad one
.
Sorry that's just my view
