In 2012–13 Haywards Heath were Division Three runners-up, resulting in promotion to Division Two. The division was renamed Division One in 2015 when the league was rebranded as the Southern Combination and the club went on to win the Division One title in 2015–16, earning promotion to the Premier Division. They finished top of the Premier Division the following season and were due to be promoted to Division One South of the Isthmian League. However, after being penalised with a nine-point deduction for fielding in several matches a player who was serving a ban, the championship was awarded to Shoreham. The club went on to win the Premier Division in 2017–18, earning promotion to the newly formed South East Division of the Isthmian League.
