The Energia All-Ireland League is the pinnacle of the club game in Ireland.

At the start of the 2025/26 season the IRFU Rugby Committee has confirmed there will be a restructure to the Men's Divisions for the 2026/27 season. 

A central focus of the review has been on how to make the league more sustainable for clubs and players. As a result, the IRFU confirmed it will move ahead with plans to restructure Divisions 2B and 2C into Energia All-Ireland League 2BN (North) and Energia All-Ireland League 2BS (South) – starting from the 2026/27 season.

To form the divisions, a notional line will be drawn between O’Connell Bridge in Dublin and Eyre Square, Galway. Clubs north of this line will participate in 2BN, while clubs south of this line will participate in 2BS.

The IRFU will ensure an even spread of clubs across both divisions should future relegation/promotion affect the balance.
