Crest: Out of a Coronet composed of four Ears of Wheat and as many Acorns slipped and leaved set alternately upon a Rim Or, a demi-Lion Argent about the neck a Rope proper entwined there with a Key fessewise Sable and between the forepaws a Flaxbreaker Gold.

The arms were officially granted on January 8, 1975.

The arms are a combination of the arms of the former Borough of Guildford with the addition of a gold border charged with the Cornish Coughs from the arms of the Guildford RDC.

The crest is very similar to that of the Guildford RDC, suitably differenced by the substitution of a key for the original anchor, which presumably is derived from the keys in the County arms.
