IBM Clubs have historically fallen into two categories: National Clubs typically based at IBM locations or associated with a former IBM location, and Retiree Clubs typically serving a geographical area for the benefit of those retiring and living in that area.

National Clubs use the UK IBM Clubs constitution, and from time to time agree changes to this constitution at National Committee meetings. Following the acceptance of changes by the National Committee, National Clubs adopt the revisions at their next general meeting.

The Retiree Clubs each use a variant of the Retiree Club constitution. Please refer to each Retiree Club's web site for more information.

IBM Club Hursley is an exception due to its status as a Registered Members Club under the terms of the Licensing Act. For more information visit the Hursley Club web site.
