Hi. My DS is 19 and at university. He doesn't have his own car, but I insure him to drive mine when he is home - just as I did with his older sister. For the next 6 months I cannot see him driving my car very much, but he will when he returns home for the summer. My insurance is due for renewal - the quote for just me is £200 per annum and for me and him it's £700 per annum. Is there anything stopping me taking out the £200 one, paying monthly and cancelling it after 6 months to take out a policy for me and him and then cancelling that one when he returns in October. Thoughts ?
