A fifth win in a row and a fourth successive clean sheet for Llangefni put them six points clear at the Group A summit.
In a testing first half for both sides made difficult by the strong wind, Cefni took a 26th minute lead when Catrin George’s through ball released top-scorer Jess Jones to fire into the bottom-right corner.
No further goals before the break, but early in the second half, Town took a big step towards three points by scoring twice before the hour.
From an Ellie Coulson cross, Ffion Thomas placed the ball perfectly in the right corner to make it 2-0 on 49 minutes.
In the 58th minute, Hannah Owen was fouled in the box and Jess Jones converted from the spot for her 28th goal of the season from just 12 matches.
Llangefni’s final goal was their best, resulting from a great team move.
Coulson passed the ball back to Catrin George on the edge of the box and she blasted into the top-right corner.
Northop Hall worked hard, but struggled to create any scoring chances. They finished with 10 players after having Daisy Allen dismissed for a second yellow card on 89 minutes.
Cefni’s next scheduled game is away to Amlwch Town in the Betty Pickering Cup next Sunday.
