During the 1924–25 English football season, Brentford competed in the Football League Third Division South. After finishing in 21st place, the club successfully applied for re-election. The 41 goals scored during the season is the fewest in club history.

Brentford manager Archie Mitchell conducted an overhaul of his half back and forward lines during the 1924 off-season, releasing James Kerr, Freddy Capper, Bobby Hughes, Sidney Mulford and Henry Parkinson and signing 12 new players, which included new forward Jack Allen to partner Reginald Parker in attack. Aside from a three-match winning streak in September which lifted the club as high as 9th, 10 defeats in the following 12 games saw Mitchell step down as manager after a 5–3 defeat to Isthmian League side St Albans City in the FA Cup fifth qualifying round on 29 November 1924. He was replaced by Fred Halliday, who stepped up from an administrative role to take over as Brentford manager for the third time.

At the time of Halliday's first match in charge, Brentford had been rooted to the bottom of the Third Division South since 1 November 1924. Halliday fared little better than his predecessor, despite a 10 match spell from mid-December to early February which saw the Bees lose just three times. Incoming signings Jimmy McCree, Bert Young and new captain Alex Graham failed to strengthen the team, though four goals in 9 late-season appearances from new acquisition Jack Lane at least inspired the team to score 12 goals in the matches in which he played.
