Lowestoft Town 1-2 Concord Rangers
Concord Rangers have been promoted to the Conference South for the first time in their history after winning 2-1 at Lowestoft Town in the Ryman Premier Division play-off final.
Steve King put the visitors in front early on, and Leon Gordon won the match in the 85th minute after Scott Mitchell had levelled.
Concord manager Danny Cowley said: "It's our third promotion together in six years, it's unbelievable.
"It's a special moment for the club."
Cowley added: "We are not the best team in this league, we haven't got the best players in this league, but we have got the biggest spirit and the most character."
A crowd of 2,490 packed into Crown Meadow and saw Lowestoft lose the play-off final for the third year in succession.
Their joint-manager Micky Chapman said: "To see another side dancing on your home patch, after you've not been successful, hurts."
Concord Rangers, who are based on Canvey Island, have had a rapid rise through the non-league pyramid.
They won the Essex Senior League title in 2008 and then won promotion from Ryman Division One North in 2010.
Lowestoft have had a similar ascendency. They won the Eastern Counties League in 2009 and were promoted with Concord as champions in 2010.
