[4] This stance changed at the beginning of 1996, when permission was granted to introduce professional football, including a new Aktieselskab (a holding company of sorts) with its own separate management, with the aim of ensuring greater continuity in the first-team squad.

[8][9] The first team which was represented in the higher tiers was renamed FC Egedal on 1 July 2009, and a new logo was created alongside a new green and white uniform, with plans of functioning as a professional superstructure of its parent club after an approval was granted by the Danish Football Union (DBU).

[14] However, all plans were abandoned shortly after, at the end of July of the same year, due to major financial problems in the professional company behind the elite team.

[15][16] As a consequence of its filing for bankruptcy in the DBU, the first team was forcibly relegated down two divisions before the start of the new season, and had to start the 2009–10 season in the highest regional division of the DBU Zealand, the Zealand Series.

[17] In 2015, Stenløse left the merger, and Ølstykke FC was re-established in Series 3, one of the bottom tiers of Danish football.
