Ossett United was created on 1 June 2018 following the merger of Ossett Town A.F.C. (est. 1936) and Ossett Albion A.F.C. (est. 1944). Both predecessors had managed to gain and retain Northern Premier League status for long periods. The new club made its new home at Ingfield, the previous home of Ossett Town, and used Dimple Wells, the previous home of Ossett Albion, as its ladies and academy team base.

Despite a successful first season on the pitch (reaching the play-off semi-final and winning the County Cup, under manager Andy Welsh), the club suffered several board resignations and some challenging financial issues. By the end of the 2018–19 season, Phil Smith had become club chairman with Stuart Garside, Steve Hanks, Paul Billing, Neil Spofforth and Joe Hanks joining the board.

Welsh left Ossett early the following season. In November 2019, the club lost a court case, relating to a match in 2015 when Ossett Town played Radcliffe Borough, leaving United facing legal and damages costs of £135,000. A loan from two supporters helped the club avoid going into liquidation (at worst) or selling the Ingfield ground (at best). The 2019–20 and 2020–21 seasons were terminated due to the COVID-19 pandemic.

In 2020, James Rogers became chairman, a role he had previously held at Ossett Town. Also in 2020, the club declared Dimple Wells surplus to requirements and made arrangements to surrender the lease making Ingfield the single home of the united club. Various ground improvements at Ingfield followed, including replacement of the pitch-side barrier and installation of LED floodlights in 2021, and changing room improvements in 2023 supported by Football Foundation grants. The improvements added a match official room, two offices and a medical room (a larger changing room will become fully operational by the summer of 2024).

Wayne Benn, assisted by Chick Hayward, had succeeded Welsh as Ossett United manager. Playing in Division One East in 2021–22, Ossett United were in the top half of the table, but a run of only one win in three months saw a change in the dugout before Christmas 2021, with Jas Colliver and Mark Ward taking a joint managerial role. The season ended well with the pair unbeaten at Ingfield with seven wins and two draws but away from home inconsistent performances and results saw a ninth place finish in only the club's second completed season.

Colliver and Ward strengthened the squad before the 2022–23 season but results did not match expectations. Ward resigned in September 2022 with Colliver taking sole charge before leaving the club by mutual consent the following month. Grant Black became the club's fourth permanent manager in October 2022, winning his first game in charge, 2–0 at the eventual play-off champions Long Eaton United and only tasting defeat twice in his first 16 games. Results tailed off, however, and the club finished 15th.

In summer 2023, the boardroom was strengthened by the appointments of Dawn Rogers and Kate Hennighan. After a 4–1 defeat to Sheffield FC, Black was sacked on Christmas Eve 2023.
