You can choose to pay monthly or annually for your policy but please note, you can't switch your payment frequency during your policy.
If you've chosen to pay your premium annually, your payment will be taken at the point of purchasing your policy.
If you've opted for monthly payments, you'll pay the first one at the point of purchasing your policy and each month following will be charged one month from your policy start date, minus 5 days. For example, if your policy started on 10th December, your monthly charge will be on the 5th of every month starting 5th January.
