Kilburn Athletic will play in the regional premier division next season after a 94th-minute winner from captain Tom Beale sent a packed home ground into delirium.
Trailing with eight minutes to play, Athletic scored twice to win 3-2 and clinch promotion with a game to spare.
A long wait ends
It is the club's first promotion in eleven years, and manager Cara Lindqvist said the result was reward for a season of discipline.
I'm proud of every single one of them. They never stopped believing.
Celebrations spilled onto the pitch at full time, and the club has announced an open-top bus parade along the High Road for Wednesday evening.
