This is a listing of clubs using the probusclub.net website service. More clubs coming soon …
Whilst there is no central control of Probus clubs, there are at least two other sites which keep a directory. If you use this website service you should ensure that both of the sites below are notified of your new web address.
The most complete listing is probably held on probus.org. This is a operated by Probus Canada but there is a UK and Northern Ireland page which has a set of PDF files listing all known clubs alphabetically. Be aware that mixed clubs and ladies clubs are listed separately, and there is another separate list of clubs with websites, so you may not always find clubs where you expect to.
You can also find a register of clubs at probusonline.org (Probus Media Services). This is a free listing service available to all clubs and is generally updated more often than the probus.org list.
