Founded in 1935 Blackfield & Langley FC has progressed from the Southampton Junior League, through the Senior and Hampshire League to the Wessex League.

After playing in the war time Hythe and District League the Club joined the Southampton Junior League and in 1946 won the Division One title and appeared in the final of the Senior Cup losing to NDLC. However, the following season they won the Cup and were Southampton League West champions. After this with progression in mind the Club applied to join the Hampshire League and when they were accepted made their debut in Division Three West in the 1950/51 season. Although they won the title the following season, the Club did not move into Division Two until 1956/57. They remained in this Division for the next four seasons but were relegated at the end of the 1959/60 season.

Bad fortune lasted for 15 years as the Club dropped into Division Four, were promoted in 1974/75 after finishing third but dropped back again in 1979/80. Then in 1981/82 the Hampshire League re-organised and Division Four was swallowed up by Division Three and as runners-up promotion was secured to Division Two.

After three seasons in Division Two, promotion was gained to the top Division, overhauling run away leaders Locks Heath, with a last match win at Cowes. In the first season in the top flight the Club finished a creditable tenth. In the following seasons the Club established itself as one of the most consistent teams n the League with eleven top ten finishes including, three second places and then won the elusive Championship in 1997/98.

With the establishment of the Wessex League in 1986/87 Blackfield & Langley recognised that to compete against the best in local football the long term aim had to be elevation to the new League. With the emphasis for entry into the League being on facilities as much as ability on the pitch negotiations were opened with Fawley District Council for a long lease on the ground which gave the Club the necessary security to develop it to the required standard.

The pitch at Gang Warily was identified and the Council provided a playing surface that is the envy of many teams. The Chairman at the time, Hans McDonald, his sucessor Ian Hoare and an enthusiastic Committee set about bringing the ground up to standard. The best opportunity came in the Championship year 1997/98 but the funds ran out to complete the ground improvements, so second placed Moneyfields were promoted. The Clubs' chance for promotion came two years later when a last match win over West Wight Mayflower earned them the third place required and the dream had been realised after 50 seasons of Hampshire League Football.

After five years in Wessex Division One the Club were relegated to the newly formed Division Two.

Over the years Blackfield & Langley has had their fair share of Cup success. In the 1980/90's the Club made six appearances at The Dell in the Southampton Senior Cup to add to the two in the 1940's, ending up as winners in four of them. The last success in 1998 producing a League and Cup double. In the 2000 final the Club suffered the agony of losing 2-1 in a replay to AC Delco after a power failure lead to the abandonment of the first game with 15 minutes to go and with a 2-0 lead. The Club were losing finalists in the Russell Cotes Cup in 1986, the Hampshire Youth League Cup in 1991 and the Hampshire Youth Floodlit Final in 1998. The Club had two firsts in the season 2004-05 when they became only the second Club in Hampshire football to be awarded the FA Adult Standard Charter and the first Ladies team was started in the Hampshire Ladies County League.
