An early goal by Reece Meekums put Adam Hinshelwood’s National South team on their way to securing a last-eght spot and Callum Kealy and Ollie Pearce (twice) struck in the second half to make sure of the win.
It was a brave effort by Dean Cox’s Isthmian south east hosts and they now go back to focusing on their league campaign.
