If you think that policy non-renewal and cancellation is the same thing, think again. There's a substantial difference between these two. Generally an insurer hasn't the right to cancel a home insurance policy that is active for more than 60 days except when:

• Your premium is not paid in time
• You have misrepresented or committed fraud on your policy.

In case of a non-renewal it's either you or the insurer who decides to stop cooperation when the policy expires. In case it is your insurance company opting for non-renewal, you can contact their customer support to know the reason of such a decision.
