This is essentially a list of club and county sites in the SCCU. It will not be complete. Every so often we come across a site we didn't know about. If we're not listing yours, tell us!
We give a few (inter)national sites, but it is only a selection. For other British chess sites we refer you to the ECF's lists of clubs etc and other chess services. Tryfon Gavriel's UK Web Chess Guide is useful but not up to date.
Some of the sites in this list have gone extinct over the years, and others appear dormant. They are retained in the list, but with markers: see key at foot of page.

The sites that play music at you are not marked, but you'll find them.
