With his game time limited due to the goalscoring form of Paul Benson and Andre Gray, Luton loaned Wall to fellow Conference side Dartford for one month on 17 January 2014. His presence had an immediate impact as Dartford picked up 10 points from a possible 12 with Wall in the team, leading to his loan being extended for another month. Luton allowed Dartford to extend Wall's loan for a further month in mid-March, but opted to recall him only a few weeks later after he had scored six goals in 11 games. Wall played a part in Luton's final four games of the 2013–14 season, scoring twice, as the club won the Conference Premier title and promotion to the Football League with a club-record 101 points.
