Our fees apply per calendar year. If you join during the year, your fee will be prorated if you join after January, apart from the Undergraduate Student package which is a one-off payment for the duration of your course and up to 18 months following.

Members opting to pay their fees by Direct Debit pay a reduced subscription rate. Current members not already on DD payment who wish to set up a Direct Debit payment can now do so online. Please follow the online payment process after logging in on My IOM3.
