During the early 1920s Pontypool was one of several major Welsh clubs to suffer from the emergence of professional rugby in England. The club's second Welsh Club Championship came in 1920/21. In the 1921–22 season Pontypool RFC began with only seven players available to them on their roster as players moved to clubs that paid a wage to play. Pontypool RFC continued to struggle through the 1920s, even though their success on the field was impressive. In 1927 Pontypool were victorious against the Waratahs and the Maoris but were two thousand pounds in debt, and the WRU's refusal to allow them a fixture against the South African national team caused local resentment. However Pontypool won back-to-back Welsh Club Championships in seasons 1931/32 and then 1932/33.
