Ben Greenhalgh, Jack Paxman and Charley Robertson will be back at the Gallagher next season.
The three midfielders have agreed deals with Jay Saunders to be part of the squad that will take on National League South.
Greenhalgh, who rejoined the club last August, made 46 appearances during the championship-winning campaign – scoring nine goals in all competitions. It was his cross that Frannie Collin headed home in the dramatic FA Cup replay win over Stevenage.
After impressing in his first few weeks with the club, Jack Paxman has the opportunity to show what he can do at the next level. The 21-year-old has experience of Conference South football following a spell with Chelmsford City at the start of the 2013/14 season.
Robertson, who scored a goal in the Stones’ opening league match against Met Police, featured in a few cup matches before a loan spell in a Faversham team that made it to the play-off semi final.
Saunders said: “I am pleased to get these three back for next season. They bring different qualities to the side and offer options across the midfield. There’s going to be times next season where we have to change the shape and having that strength in depth is important at this level.”
