Initially the club played in the Newport & District League, winning the Division 2 Section A title in 1925–26.

A few years later the seniors disbanded and only junior sides were run, however in the early 1960s the club was reformed under the new name of Cwmbran Catholics.

The side gained successive promotions from the 3rd to the 1st division between 1999 and 2001 and in season 1999–00 they won the Gwent County league cup.

As runners-up Cwmbran Celtic applied for the promotion place, and the Welsh League accepted the club's application.
