In their next league game Neath travel to Cardiff where they will be presented with the Principality Premiership trophy, and the parade could take place when Neath place Swansea or Pontypridd in the coming weeks.
Neath Head Coach Rowland Phillips has said, "As the news filtered in from Eugene Cross Park last night the realisation that we had won the league became a reality.
"As a squad, team and club we are really pleased with our league title achievement but any thoughts that this would drop our intensity and attitude for the rest of the season would be mistaken. We are a proud club with a tremendous history built on hard work and tremendous attitude and these qualities will be shown at the forefront of our game for the remainder of the season.
"Congratulations to the players and the rest of the staff at Neath Rugby on their efforts to date but we are mindful now that we need to keep performing until the end of the season.
"From a personal point of view it's been a challenging season so far but the extra work and sacrifices we have put through during since September makes it all worthwhile."
