The National League System comprises the seven levels of the English football league system immediately below the level of the Premier League and the English Football League. It contains 84 league competitions and more than 1,600 clubs. It comes under the jurisdiction of The Football Association. The National League System has a hierarchical format with promotion and relegation between leagues at different levels. For details of leagues above and below the National League System, see the English football league system.
The system underwent a rearrangement from 2004 to 2008. Phase one went into operation in 2004–05. At the start of the 2006–07 season, phase two was introduced, and a further phase three started from 2007–08 with the starting of a second Step 4 league in the north of England.
At the top of the National League System pyramid is the National League. Its top division, also called the National League (currently called the Vanarama National League), is the only division in the System which is organised on a national rather than regional basis. Although the National League is the top level of the non-league pyramid, it is not the highest level of English football (it is actually the fifth overall division). The Premier League and the three divisions of the English Football League (EFL) comprise the top 92 clubs in the English game, and two teams from the National League are able to achieve promotion to the lowest division of the EFL each season.
Below the National League, the layers have progressively more leagues and cover ever smaller geographical areas. Some leagues have more than one division. At the lower levels the existence of leagues becomes intermittent, although in some areas there are as many as twenty layers.
All the leagues are bound together by the principle of promotion and relegation. Clubs that are successful in their league can rise higher in the pyramid, whilst those that finish at the bottom can find themselves sinking further down. In theory it is possible for a lowly local amateur club to rise to the pinnacle of the English game and become champions of the Premier League. While this may be unlikely in practice, there certainly is significant movement within the pyramid. The number of teams promoted between leagues or divisions varies, and promotion is usually contingent on meeting criteria set by the higher league, especially concerning appropriate facilities and finances. In particular, clubs that hope to be promoted from Step 5 leagues to Step 4 must apply in advance to be assessed for whether they meet the grading requirements. The teams must then also finish in the top 3 in their league to be considered for promotion, which is not automatic. For instance, in the 2005–06 season 100 clubs applied to be considered for promotion, of which 51 met the grading requirements, and 29 of those finished in the top 3 in their leagues (With an additional division commencing at Step 4 in 2006–07, all 29 clubs had their promotions accepted).
