Please note that if you are not a member of any u3a, then you cannot join any of our Interest Groups. 

However, our Joint and Open Groups are available to members of other u3as, as explained below. 

Interest Group Membership

  • Interest Groups fall into one of 3 categories:
    •  Croxley Green Groups  They are only open to Croxley Green members.

    • Open Groups – these are groups which are open for members of other u3as to apply to join. Any “Guest Members” need to apply via our Groups Co-ordinator, who will liaise with their parent u3a. If the application is successful, they will become an associate (non-paying) member of our u3a.

      Croxley Green u3a members  take precedence, and associates will be asked to leave if the group fills, to avoid our paying members being on the waiting list to join. Associate members will not be permitted to join Croxley Green Groups, to attend Monthly meetings or the AGM. Our Groups Coordinator can be contacted at

    • Joint Groups – these are groups, which are run jointly with other u3as; examples being Strollers, and Sailing. They are open to members of any of the u3as jointly running them. Members should apply to join the group via their own u3a. 

    Joint and Open Groups cab be found by navigating to the   "Categories" Tab of the "Our Groups" Page.
