New Brompton's first Southern League game was away to
Sheppey United on 15 September 1894. In front of approximately 3,000 spectators, New Brompton were forced to begin with only ten players as
goalkeeper A. Russell failed to arrive. The team played with no goalkeeper for around ten minutes until the
forward Alf Jenner assumed the position and a reserve player took to the field. New Brompton emerged victorious by a score of 6–0, Hutcheson scoring a
hat-trick. The first game at New Brompton's home,
the Athletic Ground, took place a week later and resulted in a 4–0 victory over
Uxbridge, who played the whole game with only ten men. In the team's final game of the calendar year, they won 7–2 away to
Chesham. A. Webb made his only competitive appearance for the team and scored a hat-trick. On 19 January,
half-back L. Watson made his debut in the game at home to
Maidenhead, having been signed by the club after he impressed them with his performance in an inter-county match between teams representing
Kent and
Sussex. W. Thomas also made his debut and scored one of the goals. A week later, New Brompton defeated Sheppey 3–1 at home to maintain their record of having won every league game. The
Athletic News reported that Sheppey had their goalkeeper to thank for keeping the margin of the defeat down. The writer noted that Russell, New Brompton's goalkeeper, was "almost a spectator". New Brompton's run of victories continued with wins away to Maidenhead and Uxbridge, both without conceding a goal. The team scored two goals in the latter game, the fewest they had yet achieved in a Southern League match, and an Uxbridge newspaper reporter wrote that he had heard that the New Brompton players "admitted that it was the toughest fight they have had in the League tournament". New Brompton's only league defeat of the season came on 9 March when they lost 3–1 at home to
Bromley.
Athletic News columnist "Grasshopper" attributed the defeat to "the deplorable state of the ground". Dickenson was absent from the team for the only time during the season. Two weeks later the teams met again at Bromley's ground and New Brompton won 3–2 in what the
East Kent Gazette described as a "keen struggle". The team's final two games of the regular league season took place on consecutive days. On 12 April, they beat Old St Stephen's 6–0 away from home; Rule scored three of the goals, the team's third Southern League hat-trick of the season. The following day New Brompton played Chesham at home and won 9–0; ''
Lloyd's Weekly Newspaper'' reported that the team "simply made rings round their opposition". Rule scored five goals to take his total for the league season to 18. New Brompton finished the season with 11 wins in 12 games; their total of 57 goals was more than twice that achieved by any other team in the division. Rule alone scored more goals than the entire team of fourth-placed Uxbridge. The Southern League ultimately expanded Division One from nine teams to ten for the subsequent season, so Swindon retained their place despite losing the match.
