Since 2019–20, the Football Association of Wales runs the second tier for the first time after a review of the Welsh league pyramid. Tier 2 is split into a northern and central Wales league, Cymru North, and a corresponding league for southern Wales. Cymru South. The champions of each of these leagues can be promoted to the Cymru Premier, subject to acceptable ground facilities, and if the champions cannot meet the criteria the runner-up team may be considered. The Cymru North replaced the Cymru Alliance whilst the Cymru South incorporated most the clubs of the then highest division of the Welsh Football League.
Since the 2020–21 season, the Football Association of Wales has run the third tier after a review of the Welsh league pyramid. Tier 3, called the Ardal Leagues is split into a Northern and Southern League, with each league divided into two regionally based divisions, giving North East, North West, South East and South West leagues, each consisting of a maximum of 16 clubs. In an attempt to avoid dividing the current Mid-Wales teams across all four leagues, the North-East league contains a large contingent of the Mid-Wales teams. The North-West league contains the sides near the North Wales coast. To be eligible to join the league, clubs need to meet the criteria for FAW tier 3 certification. The Ardal Leagues structure replaces the former tier 3 leagues: Welsh Football League Division One, Mid Wales Football League Division One, Welsh Alliance League Division 1 and the Welsh National League Premier Division, leagues based in South Wales, Mid Wales, North West Wales and North East Wales respectively.
Tier 4: Area leagues
Below this are six local tier 4 leagues, each run by one of the area associations of Welsh football:
The winners of each league are eligible for promotion to the Ardal Leagues subject to meeting FAW tier 3 certification. In the event that winners do not meet the criteria, the runner-up is also eligible for promotion, again subject to meeting the same tier 3 certification requirements.
Local leagues are affiliated to Gwent FA, South Wales FA, and West Wales FA respectively, with promotion up the pyramid possible. In the Gwent Football Association Area, clubs from the Newport and District, East Gwent, Gwent Central and North Gwent leagues have a promotion pathway to Division Two of the Gwent County League. Champions of these leagues are eligible for promotion if they satisfy FAW criteria. The South Wales Alliance League offers a promotion pathway to leagues affiliated to the South Wales Football Association. Champions of local leagues in the towns and cities of South Wales play off to be promoted into the South Wales Alliance Division Two, subject to meeting licencing requirements. The West Wales FA area has had its own Premier League since its creation in 2020, having previously having been the only FA area to not have one. Promotion to this tier 4 league is possible from the champions of the (Pembrokeshire, Carmarthenshire, Swansea Senior and Neath & District Leagues, subject to meeting FAW licencing requirements. The top divisions of each of these leagues are at tier 5.
