The British Chess Variants Society (or BCVS) was an association of chess variant players and developers active between 1997 and 2010. The Society took over publication of "Variant Chess", a chess variant magazine which had been published since 1990; the magazine ceased publication with the dissolution of the Society.
The BCVS was actually formed prior to 1997 but it was not active because there wasn't enough interest until later.
