Subscriptions to the Association are paid by instalments, currently £40 per term, invoiced on the School bill every term while the pupil is at the School.

Members of the School become Full Members of the Association on leaving, if all the instalments have been paid. This membership is for life.

Old Lyonians who left the School before the above arrangements came into force (i.e. leavers in July 2006 or before) are deemed to be Full Members of the Association.
