Subscription Fees

All subscription fees run on an annual basis from 1st January to 31st December each year. Fees are not dependent on the date of joining and therefore not prorated. 

Fees due when applying for membership

If you are applying to upgrade your membership, your current subscription fees must be paid in full for your membership to remain active. Once the application has been approved, you will be charged for the remaining amount associated with your new grade of membership.
