I have my own insurance with Tesco and want to allow my son to drive my car but using Marmalade Insurance on my car, as I can pay "as you go". Everything I have researched indicates this is fine but when I tried to contact Tesco to double check the man on the phone had no idea what I was on about and thought I wanted to add him as a named driver. Has anyone had experience of insuring one car but with each driver having their own insurance policy. Also is there any other way to contact Tesco with a query without phoning??
