The six golden clarions or trumpets on a red ground are the arms the extinct Keynsham Abbey, and the wavy blue and white bars represent the rivers Avon and Chew. It has been suggested that the appearance of six clarions is due to the combining of the three clarions of the de Clares, Earls of Gloucester, with the three of the Greenville family who were also of great influence in the district in bygone times, but this is not so. The original arms of the de Clares show six clarions, later reduced to three, and it was the early version which was adopted by Keynsham Abbey from its founder and patron William, Earl of Gloucester.
The wreath and mantling are in red and gold, the colours of the Abbey arms and also those of Somerset County Council. The Roman crown alludes to the Roman occupation and the golden dragon of Wessex, refers both to our Saxon history and to the old brass industry of Keynsham and Saltford. One of the badges of the former "Society of Mineral and Battery Works" was a golden dragon. A more specific reference to this formerly important local industry is the brass wire around the dragon's neck, on which is threaded a cogwheel to represent modern industries. Between the dragon's claws is the basic family shield of the Brydges or Bridges, in reference to their long connection with the district. The motto is also theirs.

The gold background is taken from the arms of the Somerset County Council and the 'pall' or Y- shapad figure, suggests the initial of the name and also the junction of two Roman roads, one of them the Fosse Way, near Ilchester. The white wavy 'pall' alludes to the River Yeo or Ivel, which gives its name to Ilchester and Yeovil, and means 'the forked river' as in the Welsh 'yr eifl' (the forks). The purple colour recalls Imperial Rome and the many Roman associations of the district. The green 'chief' refers to the pastoral character of the District and the crown of wheat-ears and acorns is one specially devised for Rural District Councils. The white gloves refer to the distinctive local industry.
The eagle is, again, a reference to Roman history and has its wings inverted as on the Roman standards. It also refers to the Fleet Air Arm station at Yeovilton and to the Monteagle family of Martock, for whose arms eagles were the supporters. The star and crescent on its breast are derived from the ancient borough seal of Ilchester, which no doubt bore them in reference to King John, to whom the device is attributed as a badge. Three of the four red roses come from the arms of the Phelips family of Montacute; the other is from those of Cardinal Wolsey, whose first living was that of Limington. The gold bezants on the eagle's wings refer to the connection of the district with the Duchy of Cornwall.
