This season is the second to be "ring-fenced" with the champion club not being promoted due to changes in the Principality Premiership.

The competition was won again by Pontypool who completed the feat of going a whole season unbeaten, winning all 22 games.

The bottom two clubs that were relegated were Skewen and Glynneath (both to 1 West Cenrtral).

The bottom two clubs at the end of the season will be relegated to Division 1 (based on geographical location).

This season saw the return of playoffs between the Division 1 East and East Central champions and Division 1 West and West Central champions to determine which clubs will participate in this year's Championship.
