Their first games of the campaign were postponed until a suitable venue could be found, with the owner Craig Bown eventually acquiring the use of Birmingham Sports Centre for the duration of the season.
- With their 68–66 win in the BBL Trophy Final against Brighton Bears, Chester Jets made history as the first team to win the Trophy for four consecutive seasons.
