Income Protection Insurance - Can they cancel it at any time?

InsideInsurance

The average customer is not going to be better off by having optional insurance, if that were the case insurers would be losing masses of money. Optional insurance is about trading the risk of losing a large sum of money (your house burns down) for definitely losing a small amount of money (your premium). Depending on how risk adverse you are will dictate which you consider a reasonable risk to shoulder yourself and which are worth buying insurance for.
