On 28 July 2020, The Football Association of Wales announced that this league would be named Ardal SW and would be sponsored by Floodlighting and Electrical Services. Ardal SE & Ardal SW divisions will make up the Ardal Southern region of tier 3 in the men's Welsh domestic game.[2]
Since anti-COVID-19 restrictions were put in place by FAW, clubs could have trained in groups of 15 and contact training was allowed at all levels of football. However, competitive and exhibition matches were still not allowed to take place.[3]
