The green background, suggest the Beckenham of old, a township in a rural setting and modern Beckenham, with its parks and open spaces, to which the trees also refer. The wavy line represents the River Beck, echoing the name of the town, and the horse is from the arms of the County Council.
The lion is derived from the heraldry of the Cator family, owners of large estates for many generations. The staff and mitre stand for Bishop Odo, of Bayeux, who received the land and manors of Beckenham from his half-brother, William the Conqueror.
The supporters recall Tudor days, when at Wickham Court, we are told Henry VIII wooed and won Anne Boleyn.
