Please understand that although super top up plans may be cheap but they come with a lot of limitations (room rent limit, no restoration benefit, Zero No Claim bonus, Deductibles, etc). Also, from what I've noticed if you just go for a super top up plan (without the base plan) the insurance company will be very strict since you're getting high cover for low premiumCan one can by a super topup without the need of a base plan.
As there is a deductible limit to use the super top up, if one is ready to pay the deductible limit out of his own pocket then can he directly buy a super top up plan without the need of a base plan
