Coagh United clinched the third-tier championship of Northern Irish football, which is now known as the NIFL Premier Intermediate League, in the 2003–04 season.
They were crowned champions of the third-tier for a second time in the 2011–12 season after an intense title race with Dundela and Knockbreda F.C..
In the 2022–23 season, Coagh United emerged as the champions of the Ballymena & Provincial Football League. This entered them into a play-off for promotion to the Premier Intermediate with Oxford Sunnyside and Rathfriland Rangers, who had won the Mid-Ulster League and NAFL Premier Division respectively. In the end, Rathfriland and Coagh earned promotion to the NIFL Premier Intermediate League. Upon their return to the third tier of Northern Irish football, Coagh would end the season in 7th place in what was a difficult season.
