If you previously had cover for three years or more but you cancel your insurance, you will be given credit for any periods without cover that began on or after 1 February 2019. The minimum period of cover that you can get credit for is six months. The maximum credit that you can receive is for one or more periods of six months or more adding up to a maximum of three years.
The three years don’t need to be made up of consecutive six-month periods, but when all periods are added together they must not exceed three years of being uninsured. The reason why you cancelled your insurance doesn’t matter under this provision.
