with the club went into insolvency. Unable to afford to complete the new stadium on their own, Wealdstone were forced to leave the site unfinished for two years, until Harrow Council, frustrated that the site was still unused and falling into disrepair, eventually sold the site lease to Barnet F.C., who used it as a training centre before later moving permanently in to what became The Hive Stadium in 2013. In 2004 Wealdstone were promoted to the Isthmian League Premier Division as a result of the creation of the Conference North and South. The club faced Dulwich Hamlet in the playoff final, with the game finishing 2-2 before Wealdstone won 5-4 on penalties. The club's first two seasons at Premier Division level saw them steer clear of relegation, with back to back 18th placed finishes. Off the pitch, the club began a further new groundshare arrangement in 2005, this time moving to Northwood's Chestnut Avenue ground. In 2006 they were switched under FA reorganisation to the Southern League Premier Division for a single season, before returning to the Isthmian League the following season. In January 2008, Wealdstone acquired Ruislip Sports and Social club and the associated lease at Ruislip Manor's Grosvenor Vale ground, starting the 2008-09 season there. With the ground share agreement at Northwood coming to an end and still no specific completion date in sight for the club's Prince Edward Playing Field project, Wealdstone instead decided to invest in the Grosvenor Vale stadium to upgrade the playing facilities as a priority, in order to meet the necessary ground grading requirements to play Isthmian League Premier Division football in the 2008–09 season. The club's first 3 seasons at the Vale saw the club fail to reach the playoffs, finishing 7th, 6th and then 12th. They did however reach the first round of the FA Cup in 2009-10, where they lost 3-2 at home to Rotherham United 2011–12 saw Wealdstone embark on a run the FA Trophy which saw them reach the semi-final and knock out three teams from higher divisions. A 2-1 win at home to Conference side Barrow and a 1-0 win in a replay against Dartford of the Conference South set up a quarter-final away at Cambridge United which Wealdstone won 2-1 thanks to a Richard Jolly brace, before eventually losing 3–1 on aggregate to Newport County in the semi-final. They also reached the promotion play-offs in
