Percival Hilton was signed from Everton in the summer of 1920, but made just one Football League appearance for the Grecians, in a 3-0 defeat at Southampton in April 1921. He then signed for Torquay United for the following season.

He played in the Manchester Junior League with the South Wales Borders based at Heaton Command Depot. In wartime football he assisted both Everton and Bolton Wanderers, before returning to Everton to play for their reserves in 1919-20.

In February 1951 he was coaching the reserves at Exeter in the Southern League as reported in the Express and Echo 

Reserves "shone
PERCY HILTON, an Exeter City inside-forward just after the First World War, a past chairman of the Grecians' Association, and one of the club's most loyal fans, was in charge of the Reserve team which lost at Tonbridge by the odd goal of three last Saturday.
His views on the game are worth quoting. "I was agreeably surprised by the standard shown by the second team," he said when I saw him this week. "At no time since the war have I seen a better display of foot ball from the City's Southern League side, and the movement which brought the goal was a classic. Nine players shared in the attack, and not one Tonbridge player touched the ball. Gordon Kaile was in great form up to the time of suffering his injury, and the City have a real capture here."
