Question: How many professional football leagues are there in the U.K.?

English football league system


The English football league system, also known as the football pyramid, is a series of interconnected leagues for men's association football clubs in England, with six teams from Wales and one from Guernsey also competing.  The system has a hierarchical format with promotion and relegation between leagues at different levels, allowing even the smallest club the theoretical possibility of ultimately rising to the very top of the system, although in practice it would take a team at the bottom levels at least two decades of consistently finishing at or near the top of each successive league to reach the top level, and even then additional restrictions, particularly in regard to stadium facilities, would then come into effect at the highest levels that could prevent a club from being allowed access to the top levels.  There are more than 140 individual leagues, containing more than 480 divisions.[1]
The exact number of clubs varies from year to year as clubs join and leave leagues, fold or merge altogether, but an estimated average of 15 clubs per division implies that more than 7,000 teams of nearly 5,300 clubs are members of a league in the English men's football league system.
As there are no official definitions of any level below 11, any references to the structure at level 12 and below should not be regarded as definitive.
The pyramid for women's football in England runs separately to nine tiers and some England-based men's clubs play outside the English football league system.
History

The (English) Football League was created in 1888 by Aston Villa director William McGregor. It was dominated by those clubs who had supported professionalism. The twelve founding members consisted of six from Lancashire (Blackburn Rovers, Burnley, Bolton Wanderers, Accrington, Everton and Preston North End) and six from the Midlands (Aston Villa, Derby County, Notts County, Stoke, West Bromwich Albion and Wolverhampton Wanderers).
About the system


The system consists of a pyramid of leagues, bound together by the principle of promotion and relegation. A certain number of the most successful clubs in each league can rise to a higher league, whilst those that finish the season at the bottom of their league can find themselves sinking down a level. In addition to sporting performance, promotion is usually contingent on meeting criteria set by the higher league, especially concerning appropriate facilities and finances.
In theory it is possible for a lowly local amateur club to achieve annual promotions and within a few years rise to the pinnacle of the English game and become champions of the Premier League. While this may be unlikely in practice (at the very least, in the short run), there certainly is significant movement within the pyramid.
The top five levels contain one division each and are nationwide in scope. Below this, the levels have progressively more parallel leagues, with each covering progressively smaller geographic areas. Many leagues have more than one division. At the lower levels the existence of leagues becomes intermittent, although in some of the more densely populated areas there are leagues more than twenty layers below the Premier League.[2] There are also leagues in various parts of the country which are not officially part of the system as they do not have formal agreements with other leagues, but are recognised at various levels by county football associations. Clubs from these leagues may, if they feel they meet the appropriate standard of play and have suitable facilities, apply to join a league which does form part of the system.
The seven levels immediately below the Premier League and English Football League are known as the National League System and come under the jurisdiction of The Football Association.[3] It evolved over many years. In the most recent major re-organisation, two new leagues were entered at level six – the Conference North and Conference South (now National League North and South) – shifting the top divisions of the Southern League, Isthmian League and Northern Premier League down to level seven.  In May 2014 The FA announced provisional plans for a new division between the English Football League and the National League which would include "B" teams of higher level clubs. They later reneged on the plan to include Premier League "B" teams in the new division[4] and shortly thereafter scrapped the idea altogether.[5]
The English football league system does not include the amateur version of the game often called Sunday league football. These leagues are independent entities with no promotion or relegation involving the football pyramid. However, some Sunday League clubs have been known to join pyramid leagues if they desire to progress higher. There are also some Saturday leagues which are not officially part of the pyramid, although teams frequently leave these for pyramid leagues. The FA admitted an erstwhile non-promoting Saturday league, the Lincolnshire League, to the pyramid in May 2017.[6]
Structure
At the top is the single division of the Premier League (Level 1, which is often referred to as the "top flight"), containing 20 clubs, all of which, up to the 2010–11 season, were based in England. However, two Welsh teams (Swansea City and Cardiff City) have since played in the league. Below the Premier League is the English Football League (EFL), which is divided into three divisions of 24 clubs each: The Championship (Level 2), League One (Level 3) and League Two (Level 4). The 92 clubs in the Premier League and English Football League are all full-time professional clubs. They are often referred to as 'League' clubs because, before the establishment of the Premier League in 1992, the EFL included all 92 clubs, in four divisions. Clubs outside this group are referred to as 'non-League' clubs, although they too play most of their football in league-type competitions.
The top tier of non-League football is the National League.  It contains a national division (National League) of 24 clubs (Level 5), and is the lowest level with a single nationwide league. There are two divisions at Level 6, covering the north (National League North) and south (National League South), with 22 clubs each. Some of these clubs are full-time professional and the others are semi-professional. Below the National League, some of the stronger clubs are semi-professional, but continuing down the tiers, soon all the clubs are amateur. Lower-level leagues also tend to cater for progressively smaller geographic regions.
Next down from the National League are three regional leagues, each associated with different geographical areas, although some overlap exists. They are the Northern Premier League (which covers the north of England, with one club from North Wales), Southern Football League (which covers the Midlands, south and southwest of England, with one club from South Wales) and the Isthmian League (which includes clubs from the south east of England as well as Guernsey from the Channel Islands). All of the leagues have Premier Divisions of 22 teams (Level 7). Below these, and split by region, the Northern Premier League and Southern Football League each have two parallel divisions of 20 teams (Level 8). The Isthmian League has three parallel level 8 divisions of 20 teams each as well.
Level 9 contains the top divisions of a large group of fourteen sub-regional leagues. Each of these leagues has a different divisional set up, but they all have one thing in common: there are yet more leagues below them, each covering smaller and smaller geographical levels.
Promotion and relegation rules for the top eight levels


Premier League (level 1, 20 teams):  The bottom three teams are relegated.
English Football League Championship (level 2, 24 teams): Top two automatically promoted; next four compete in the playoffs, with the winner gaining the third promotion spot. The bottom three are relegated.
English Football League One (level 3, 24 teams): Top two are automatically promoted; next four compete in playoffs, with the winner gaining the third promotion spot. The bottom four are relegated.
English Football League Two (level 4, 24 teams): Top three teams are automatically promoted; next four compete in playoffs, with the winner gaining the fourth promotion spot. The bottom two are relegated.
National League (level 5, 24 teams): The champions are promoted; next six compete in playoffs, with the winner gaining the second promotion spot. The bottom four are relegated to either North or South division as appropriate.
National League North and National League South (level 6, 22 teams each, running in parallel): The champions in each division are automatically promoted; next six teams in each division compete in playoffs, with the playoff winner in each division getting the second promotion spot. The bottom three teams in each division relegated to either Northern Premier League, Southern League or Isthmian League as appropriate. If, after promotion and relegation, the number of teams in the North and South divisions is not equal, one or more teams are transferred between the two divisions to even them up again.
Northern Premier League Premier Division, Southern Football League Central Division, Southern Football League South Division and Isthmian League Premier Division (level 7, 22 teams each, running in parallel): The champions in each division are automatically promoted; next four teams in each division compete in playoffs, with the four playoff winners paired off geographically for a further match to determine two more promoted teams. The bottom three teams in each division relegated to a level 8 division as appropriate. If, after promotion and relegation, the number of teams in the divisions is not equal, one or more teams are transferred between the four divisions to even them up again.
Northern Premier League Division One North, Northern Premier League Division One South, Southern Football League Division One East, Southern Football League Division One West, Isthmian League Division One North, Isthmian League Division One South Central and Isthmian League Division One South East (level 8, running in parallel, 20 teams in each division): The champions in each division are automatically promoted; next four teams in each division compete in playoffs, with the five best play-off winners by points per game being promoted. The bottom two teams in each division are relegated to a level 9 division as appropriate. If, after promotion and relegation, the number of teams in the divisions is not equal, one or more teams are transferred between the divisions to even them up again.
Cup eligibility
Being members of a league at a particular level also affects eligibility for Cup, or single-elimination, competitions.
FA Cup: Levels 1 to 10
EFL Cup: Levels 1 to 4
EFL Trophy: Levels 3 to 4
FA Trophy: Levels 5 to 8
FA Vase: Levels 9 to 11
FA Inter-league Cup: Level 11 (contested by representative teams from each league)
In the case of the FA Cup and the FA Vase, some of the clubs in the lowest level in each do not compete. For instance the 2017-18 FA Cup saw 77 teams compete from Level 10 out of the 338 in total at that level.
Below Level 11 the pyramid becomes regional and the cups become accordingly regional. Further down the pyramid is split on a county basis, counties having their own cups accordingly. This excludes some tournaments marked "Senior Cups", which often are competitions between teams representing top professional clubs in a given district, and may be little more than derbies, such as the Gloucestershire Cup, which originally included all teams in Gloucestershire, but then came to be contested as a Bristol derby.
The system
For details of changes made below the level of the English Football League, see History of the English non-League football system.
The table below shows the current structure of the system. For each division, its official name, sponsorship name (for levels 1–8, if it differs from its historic name) and number of clubs is given. At levels 1–8, each division promotes to the division(s) that lie directly above it and relegates to the division(s) that lie directly below it. Below that level, individual league articles detail promotion and relegation arrangements.
Level one in the pyramid, the top division of English football, is run by the Premier League (which gives its name to the competition in that division), the winners of which are regarded as the champions of England. Levels two to four are run by the English Football League. Together, these four divisions make up what is known as "league football".
The leagues below level four are classed as "non-League football", meaning they are outside the EFL. The leagues at levels five to eleven comprise the National League System (NLS), and come under the direct jurisdiction of the Football Association. The top level (level 5) of the NLS is known as "step 1" by the FA, the next (level 6) as "step 2", and so on.

The system is only defined as far as level 11. What follows is a representation of one possible structure, should the system be defined further.
