The urban district council adopted an unofficial coat of arms consisting of a shield bearing crossed swords between a red rose of Lancaster and a white rose of York and the Greek letter omega. This design represented the Battle of Barnet, the final battle in the Wars of the Roses. The "chief" or top third of the shield showed a fleur de lys between two flory crosses, emblems of St Mary, the patron saint of the ancient parish of East Barnet. In 1955 this became the basis for an official grant from the College of Arms. A crest was added above the shield: a hart from the arms of Hertfordshire County Council, with a shield hanging from the neck bearing the cross of St Alban for the historical associations of the Abbey of St Albans with the area. The motto adopted: "Willingness Rids Way", was from Shakespeare's "Henry VI, Part 3". It comes from a speech made by Edward IV following the Battle of Barnet.
