The Spireites only needed a point to secure top spot and promotion and they went one better by beating Boreham Wood 3-0 on Saturday.
Captain Jamie Grimes headed in Liam Mandeville’s corner on 28 minutes which lifted the roof off all four sides of a sold-out SMH Group Stadium.
The Spireites lifted the trophy in front of nearly 10,000 jubilant fans.
