There is a cost saving when paying annually versus monthly.
If you choose to pay monthly
You will pay the full service fee every month without a cost saving. For dedicated hosting, a set-up fee will also apply.
If you choose to pay annually You will receive the equivalent of 1 month (1/12) discount on the total sum.
For example, where the monthly fee would be £500 per month; the total annual fee would be
11 * £500 = £5,500
The set-up fee (if applicable) is also waived when bills are paid annually.
