They finished bottom of the league in 1922–23, but were runners-up in 1925–26. At the end of the season all the clubs in the league joined the North Eastern League as members of the new Division Two. They were the first Division Two champions in 1926–27, earning promotion to Division One. However, after finishing second-from-bottom of Division One in 1930–31, they were relegated back to Division Two. In 1932–33 Consett were Division Two runners-up and were promoted to Division One. After finishing second-from-bottom of Division One in 1934–35, they left to return the Northern Alliance, which had been re-established. However, after two seasons in the Northern Alliance, they rejoined the North Easter League, which was now running with a single division. When the league was suspended in 1939 following the outbreak of World War II, a competition was run with ten clubs, which Consett won. In 1946–47 they finished seventh in the league and subsequently applied for election to the Football League. However, no vote took place and the four clubs up for re-election retained their places in the Football League. The club went on to win the League Cup in 1950–51 and 1953–54. When the North Eastern League was disbanded in 1958, Consett spent the 1958–59 and 1959–60 seasons in the Midland League, also reaching the first round of the FA Cupfor the first time in 1958–59, losing 5–0 at Doncaster Rovers.

They finished bottom of the league in 1963–64, with the league disbanded at the end of the season. The club subsequently joined the Wearside League, They were runners-up in 1968–69 and 1969–70, after which the club joined the Northern League.

The 1988–89 season saw Consett win Division Two at the first attempt, earning an immediate return to Division One. They won the League Cup in 1994–95 with a 2–0 win over Whitby Town in the final, and in 1996–97 the club reached the first round of the FA Cup for a second time, losing 4–0 at Mansfield Town.

Ground
The club originally played at Vicarage Field, which was owned by the Consett Iron Company. Spectator facilities were restricted to a small stand, with an army hut used for changing rooms. However, in 1948 the site was needed for expansion of the steelworks. They spent two seasons at Eden Colliery Welfare's Leadgate ground before returning to Consett to play at the new Belle Vue Park ground on Ashdale Road. Built largely by volunteers, the new ground had banking around the pitch made from mine workings, with two stands erected, one of which was paid for by the £1,150 transfer fee received from Charlton Athletic for Tommy Lumley. The first match at Belle Vue Park was played in August 1950, attracting a record attendance of 7,000 to see a game against Sunderland reserves. One of the stands was later closed, although the steel structure was left in place. The remaining stand consisted of covered bench seating and a small terraced area in front. The club played at Belle Vue Park until 2013, when they moved to a new ground on Delves Lane, named Belle View Stadium; the new ground included an artificial pitch after the 2012–13 season had seen 18 matches at Belle Vue Park postponed due to the weather. The first match was played on 22 November, with Newcastle United the visitors; a crowd of 3,054 saw Newcastle win 2–1.
