In Civil's first season in Division 1 (1989–90) they swept to 2nd in the League and captured the Gwent Challenge Cup for the first time.

In the 1998–99 season Civil were on for the treble, until disaster struck with the loss of 9 points for unknowingly fielding a player suspended in Sunday Football.

They then lost Gwent Amateur Cup Final to local rivals Newport Corinthians and at the end only had the Gwent Challenge Cup to show for a season that promised so much – Civil attaining a 1–0 win over Pill, another Newport side.

In the 2001–02 season Civil Service struggled for quality players all year round which ended in relegation to the Gwent County Second Division.
