They clinched the title in style, demolishing Port Vale 8-1 in a game played at Kidsgrove Athletic on Tuesday lunchtime.
Aaron Bennett hit a hat-trick, Jacob Slater scored twice, while skipper Mikey O’Neill, Jacob Holland-Wilkinson and Josh Seary found the net.
North End were 5-1 up by half-time, with goalkeeper James Pradic saving a first-half penalty.
Two of Bennett’s goals came in the second half as PNE offered no let-up to their hosts.
The title was wrapped-up with three games to spare, underlining the PNE youngster’s good form this season.
They have only lost twice in 23 league games, while beating Vale was a 12th league and cup unbeaten.
The Under-19s have also reached the final of the national final of the Alliance Cup where they will play Luton Town at Kenilworth Road in May.
