The Borough of Broxbourne was formed by the amalgamation of the Cheshunt Urban District and the Hoddesdon Urban District.

Picture used with permission, do not reproduce.

The ermine field on the left half of the shield, like the ermine pale in the arms of the Cheshunt UDC, represents Ermine Street, the Roman road which passed through the Borough. The wavy line represents the New River and the River Lea. These physical features are common to both Hoddesdon and Cheshunt. The two chevrons are taken from the arms of Sir John Say, a mediaeval knight and politician who owned extensive lands in both Broxbourne and Cheshunt. His tomb and brass, on which his arms appear, are in Broxbourne Church. The rose and thistle, one of the badges of King James I, the first sovereign to wear the crowns of England and Scotland, recalls the fact that James owned Theobalds in Cheshunt. This badge also appeared on the arms of the Cheshunt UDC. The tree, is taken from the arms of Cheshunt and the device used by the Hoddesdon UDC. In the case of Cheshunt this was a reference to Goff's Oak, while in the Hoddesdon device the species is not apparent but, it symbolised the wooded nature of the western part of the district, in these arms the oak tree is therefore doubly significant. The Catherine wheel is taken from the device of the Hoddesdon UDC and is a reference to the ancient chapel, dedicated to St. Catherine, erected in 1336 by William de la Marche, which stood in the centre of the town.
The cross formy, as in the crest of Cheshunt, is taken from the arms of the Meux family, late of Theobalds, who were the benefactors to Cheshunt. The badger appeared in the device of the Hoddesdon UDC and was used by many of the ancient families of Broxbourne in their arms, since the name Broxbourne means 'brock's or badger's stream'.

The hart and gateway symbolise the name Hertsmere, which means the Hertfordshire boundary (with Greater London). The hart is derived from the arms of the County Council and the wall represents the boundary, the raised portcullis denoting free passage between the two 'territories', together with the idea of the protection of Herfordshire's amenities.
The oak is from the arms of the Elstree RDC and represents 'Tidwulf's Tree', which also featured in the device of Watford RDC, from whose area Aldenham is taken. The hart and spool of film are taken from the crest of Elstree RDC and refer to the County and the film industry.

The sprigs of Oak are like those in the crest of the Letchworth UDC and the mural crown is an emblem of civic government. The hooded crow from the crest of the Royston UDC, is a bird perculiar to the District.

Motto 'A BONIS AD MELIORA' - From good things to better.
Granted 19th May 1952, to the Royston Urban District Council.

The black and white chequered fesse is from the heraldry of the Stuarts, and refers to the association James I had with the Town. The hart is a reference to the County, and perhaps also to the royal hunt. The Archiepiscopal staff denotes the ancient Priory of Austin Canons, Sir Eustace de Merc, Lord of Newsells Manor, Barkway (which was one of the four parishes forming Royston), built on the site of the present Priory a chapel for three chaplains. Upon the same spot his nephew, Ralph of Rochester, founded a house of Austin Canons, to whom he gave the land on which the Priory of St. John the Baptist and St. Thomas the Martyr stood. The staff in the coat of arms was also the Seal of the Priory. The two Tudor roses are included to signify the period when the Priory was dissolved during the reign of Henry VIII.
The hooded crow is a bird peculiar to the district. The bird has by a long association with Royston dating back to 1648, gained the name of the Royston Crow. The stone on which the crow is perched is the Roys Stone, a boulder which was originally at the base of the Roys Cross which stood for several centuries at the crossing of Ermine Street and the Icknield Way.

The blue wave on a gold background represents the River Lea, with the narrower parallel wave for the River Mimram. The two willows from the crest of the Welwyn Garden City UDC and the device of the Welwyn RDC are in reference to the origin of the name Welwyn - meaning 'willow'.

The gold wheatsheaf, represents the agricultural pursuits of the area, flanked by two blue wings alluding to the local aircraft industry. The wheatsheaf is also a feature of the crest of the ancestors of the Cecils of Hatfield, particularly Lord Burghley, Queen Elizabeth's famous minister and father of Robert Cecil, the first of the family to reside at Hatfield.
The harts, like those of the County Council, are a reference to Hertfordshire. The two dividers shaped like a letter W are from the arms of the Welwyn Garden City UDC, emphasizing its character as a planned development.
