The membership year commences on 1st September. This timing coincides with the date each year when we welcome a large number of school leavers as new members. Direct Debit payments are processed during September. The expiry date of annual membership cards is 31st August.

To ensure that the Club is in compliance with GDPR regulations, any new member will be requested to complete an Application Form as well as a Payment Form. Annual members will be required to pay by Direct Debit.

Membership fees

All former pupils of Grimsdell, Belmont, Mill Hill and Mount Mill Hill International (MMHI) are eligible to join the Old Millhillians Club.

As a matter of policy, the Club sets fee levels to incentivise all eligible parties, especially younger ones, to become Life Members of the Club. For example:

  • Life membership for Junior members costs £225 to Old Millhillians and £300 to all other eligible parties. Since school leavers are now joining the Club as Life Members, we have discontinued annual membership for new Junior Members. Old Millhillian Junior Life Members receive a £75 discount because their parents have already paid £75 to the Club.
  • Life membership for a UK resident aged 45 or under costs £420, unless they qualify for Junior life membership (see above). Annual membership is £40 so the cost of becoming a life member is equivalent to being an annual member for 10.5 years (at current fee levels).
  • The life membership fee for anyone aged over 45 depends on your age. The fee is approximately 35% less than annual membership through to age 80. Members who attain the age of 80 years enjoy free membership for life (provided they have been fully paid members for at least the preceding five years).

All life membership fees may be paid in 36 equal monthly instalments by Direct Debit.
