You won’t lose your No Claims Discount (NCD) completely unless you’ve made settled fault claim against you. It will stay the same as when you joined Motorcade. NCD is awarded for each full year of insurance, so if you cancel midway through the year, your NCD will not increase.
For example, if you joined Motorcade with no previous no claims discount and cancelled 6 months into your policy having had no accidents, you will start at zero no claims discount for your next policy.
