The Chiltern Bridge League was formed in 1967 to allow clubs in South Oxfordshire and adjacent areas of Berks & Bucks to play matches while keeping travel to a minimum. In recent years constituent clubs have included a golf club and school. The league operates under license from the English Bridge Union and awards MPs on the District scale.

The league organizes leagues for Teams of Eight and Teams of Four in the period September to March. The Spring Cup for fours starts with a round-robin stage and the qualifiers proceed to the knockout stage. The League has a single pairs event, the Elimination Pairs, with heats in clubs and the qualifiers meeting for the final. The season's bridge concludes with an evening of Fours in July at which the year's trophies are presented. EBU level 3 applies to all events though club heats may use the club's standard if it is lower.

All Team of Eight captains form the committee along with the executive (President, Chairman, Treasurer). Clubs without a team of eight may choose to have a representative on the committee. The executive may co-opt members to the committee for special projects.
