Although Footman James are actually a broker, are you sure you actually got a transferable 1 years no claims? I was with them for 4 years and was awarded 'claims free years of driving' which I could only use with their classic policies and other insurance companies that accepted it. It was not 'no claims bonus', and they would not make it so or write notification of it for switching companies. When it came to normal insurance and insure a modern, I had to suck it up and start from 0.
I've heard lots of good things about Chris Knott Insurance.
