However ...................
There is some bit of legislation (I believe) that the FSA produced that forces insurers to refund your premium proportion if you cancel it. In the old days, insurers just told you that once you had had more than 6 months of a 12 months policy, you lose the rest if you cancel. Therefore, find out what a new 12 months policy cost would be for yourself, then find out whether what I am saying is valid (they may charge you a small fee (�20?) to cancel. It may worth cancelling and starting anew policy.
