Risk Exposure to Clients

I just made changes to my current policy of funeral cover to add my newborn child. I'm informed that the policy will be effective from the 1st of September and today is 24th August due to premium collection that can only happen on the 1st. In my years of experience this is strange be it with a vehicle or life cover or any insurance. What has happened in the past the effective date is immediately and insurance collects a premium (Pro-rata) to the first of the month immediately. I have been informed this is not the case with hollard, if I call on the 10th of the month to insure a life or a car or funeral it will be effective on the 1st of the upcoming month leaving clients with exposed risk until such time. It would be great to hear from hollard the logic behind this. Note: This is not a waiting period issue as that is a norm under certain conditions with insurance.
