Burton have won promotion to League Two after Cambridge failed to beat Altrincham on the final day.
The Brewers lost 2-1 at Torquay to continue their dismal run of form that has seen just three points earned from the last 18, but it was sufficient in the end as Cambridge played out a goalless draw with Altrincham.
Kidderminster miss out on the play-offs after losing at home to Kettering, leaving Cambridge, Histon, Torquay, and Stevenage to battle it out for the remaining Football League spot. Oxford missed out on the play-offs by just four points, and had five deducted earlier in the season.
