A sixth successive win for Chatham saw them beat Cray Valley to win the Isthmian South East title with a game to spare on Saturday.
They led at half-time thanks to a Jack Evans penalty before Matt Bodkins struck after the restart and, despite Denzel Gayle pulling one back for the Millers, Kevin Hake’s troops held on for their all-important 2-1 triumph as they earned promotion in their first campaign at the level.
There was much at stake for both sides so a nervy start at the Bauvill Stadium ensued. But away players Thomas Chambers and returning captain Gayle did cause early problems on the left-hand side.
Ike Orji and Che Krabbendam linked-up well on Chatham’s right in the 13th minute, only for optimistic penalty protests for a foul on player-assistant manager Danny Kedwell to be dismissed.
