Penallta RFC is a member of the Welsh Rugby Union and is a feeder club for the Newport Gwent Dragons.

[citation needed] Penallta became a full Welsh Rugby Union member in 2004 and since then it has won Divisions 3, 4 and 5 South East, plus the Silver Ball trophy in 2005.

In 2012 Penallta returned to the Millennium Stadium and won the Swalec Plate against North Wales side Nant Conwy.

Captain Kieran Mahoney lifted the trophy to cap a season during which Penallta embarked on an 18-match unbeaten run, narrowly finishing runner-up to rivals Ystrad Rhondda in the league.

Extracts from the programmes were made into a book in 2007 called "Shaking the Tree Boss - Portraits of a Welsh Rugby Club".
