Division One South is one of the two second-tier divisions of the Northern Premier League. It is at Step 4 (or level 8) of the National League System, placing it seven divisions below the Premier League. For sponsorship reasons, it is also referred to as the UniBond League Division One South.
The split of the Northern Premier League First Division resulted in the creation of the Division One South and the Division One North. The division began play at the start of the 2007-08 season, initially with 18 teams but now 22 teams for the 2009-10 season
The League operates a Double Round Robin System, where each team plays each other team Twice, once at Home and Once Away. After 42 Games the team that are placed top of the league will automatically promote to the Northern Premier League Premier Division and the 2 teams at the bottom of the league relegate to one of the feeder leagues (Usually either the North West Counties,Northern Counties East or Midlands Alliance ). The Teams that place 2nd to 5th will playoff for the final promotion spot.
However Prior to the 2008/9 season, when the league originally split from its traditional 1 division into a North and South, the league operated with 18 teams, leading to splitting the league into 2 separate groups of 9 teams each. Each team would play each team in their own group 3 times (once at home,once away then a extra game where each team received an extra 4 home games) and play the teams in the other group home and away once each.
This Changed back to the traditional format in 2008/09 when more teams entered the league
