hi, i am having some trouble with my insurance company about NCB. i have 3 cars with 3 insurers. one being my business car, family car and run around car. i am insured on my business car, my wife and i are insured on the family car, and my son and i on the 3rd car. Now i have NCB on my car and family car, but as the 3rd is a new addition to the household, i have no NCB on it. my son is a student and he uses it now and again. Does anyone know whether you can split your NCB from other insurers to put some on another car? thanks
