Division Three

Of the ten clubs in the newly formed Division Three, seven joined from the former Rugby League Conference National Division and two teams were promoted from the RLC Premier Divisions (Bristol Sonics and St Albans Centurions). The tenth club, South Wales Hornets, were a newly founded team. The Grand Final winners were Hemel Stags, defeating Underbank Rangers 17–10.

At the end of the season, all clubs apart from Underbank Rangers and Coventry Bears withdrew from the league for various reasons:
