The club was established in 1903 as Poringland and District, and initially played in the Norwich & District Business House League.^[2] In 1965 they joined Division Three of the Anglian Combination, which they went on to win at the first attempt.^[3] The club won the Norfolk Junior Cup in 1978–79, defeating Bradenham Wanderers 5–2 in the final.^[2] In 1980–81 they won the Norfolk Junior Cup again, beating Wroxham reserves in the final, and also won the Junior League Cup, defeating Acle 3–2.^[2] In 1983–84 the club won the Anglian Combination Senior Cup, beating Bradenham Wanderers 2–1.^[2] In 1987 the club was renamed Norwich United.^[2]

In 1987–88 Norwich United were Anglian Combination Premier Division runners-up, before going on to win the title the following season, earning promotion to Division One of the Eastern Counties League.^[2] In their first season in Division One they finished as runners-up,^[4] but could not be promoted due to the inadequate facilities at Gothic. The following season saw them win the division; having relocated to Plantation Park, the club were promoted to the Premier Division. They won the League Cup in 1991–92. The club were relegated back to Division One at the end of the 1993–94 season after finishing bottom of the division. The club were Division One champions in 2001–02, securing promotion back to the Premier Division.

However, they also finished bottom of Division One North and were relegated back to the Premier Division of the Eastern Counties League.^[4] They withdrew from the league shortly after the start of the 2023–24 season following the departure of several players from the club and a 12–0 defeat at home to Thetford Town (equalling a league record away win).^[6]

The club initially played at the Poringland Memorial Playing Field, where they remained until moving to Heartsease Lane – the former ground of Gothic – in 1985 in order to achieve senior status.^[7] They relocated to Plantation Park in Blofield in 1991 in order to meet the ground grading requirements of the Eastern Counties League's Premier Division.

Plantation Park has a stand on one side of the pitch, which includes a seated section in the centre and terracing on either side.^[7]
