The Harry Jepson Trophy was competed for by all the Conference sides until 2005 and the advent of Premier Divisions.
Until 2004 it was possible for a team to finish runners-up in their division, qualify for the play-offs and still win the Harry Jepson trophy, hence some champions did not pick up a regional title in the same year.
From 2005, the Harry Jepson trophy was solely for the winners of the RLC Premier divisions.
The Harry Jepson trophy is still contested by teams from RLC successor leagues.
The RLC Challenge was a knock-out competition designed to give clubs meaningful pre-season games.
