In terms of promotion the league champions would go straight up into National Division Two while the runners up would have a one-game playoff against the runners up from National Division Three North (at the home ground of the club with the superior league record) for the final promotion place.

[4] Redruth would join Barking in the 2005–06 National Division Two by defeating the 2004–05 National Division Three North runners up Macclesfield in the north–south playoff in front of a huge crowd of 4,000 fans at the Recreation Ground in Redruth.

[5] At the other end of the table Haywards Heath and Tabard were the first teams to be relegated.

Redruth were the southern division runners up and as they had a superior league record than northern runners-up, Macclesfield, they hosted the play-off match.
