Notable occurrences
- Attracted by the opening of the brand-new 4,000-seat Braehead Arena in Glasgow, Edinburgh Rocks uprooted from their aging Meadowbank venue in Edinburgh and moved 45 miles west to Scotland's largest city Glasgow, and rebranded as the Scottish Rocks. The move received a mixed response from fans; whilst many said that the move would not work, the official supporters club backed the franchise's decision.
- Although based in Brentwood, Essex for the past two years, Greater London Leopards eventually rebranded the franchise as the Essex Leopards prior to the season starting.
- Due to a decreasing membership, the league abolished the Conference system it had imposed for the past three seasons and returned the regular single-league table set-up, with the top eight teams progressing to the play-offs.
