The 2007–08 season, the 21st since the establishment of the British Basketball League, commenced on 9 September 2007, when the Plymouth Raiders succumbed to the Guildford Heat in the inaugural Cup Winners' Cup competition. The regular season started two weeks later on 21 September with 12 teams including new additions Birmingham Panthers, Everton Tigers and London Capital the later of whom stepped up from EBL Division 1 during the summer. After just one season in the top-flight, London United were forced to drop out due to the loss of its financial backer just weeks before the start of the season.
