The British Basketball League Championship, often shortened to the BBL Championship, is the top-level men's professional basketball league in the United Kingdom. Established in 1987, the competition is administered by the British Basketball League and comprises 10 teams from both England and Scotland. Each team plays a 36-game regular season, from September until April, with the team that finishes in first place being crowned as League champions.
Following the end of the regular season, the top eight-placed teams advance to the postseason Playoffs tournament to decide the winner of the BBL Playoffs.
There is currently no promotion or relegation between the second-tier English and Scottish leagues and the BBL Championship because of the franchise system in use in the BBL, although several clubs have been elected from the English Basketball League in recent years.
