Thanks guys. I really do see the point about the certificate now...doesn't really prove anything in the end! I think I'll give a few insurance companies a call and see what they say. I tried to get some quotes when I first thought about restricting it and they were mostly less than helpful, but that might be because I was a bit vague, not sure. Hubby is with BikeSure and he said that they're really helpful if they call up, so I'll try them and see what they say
