Borough coat of arms

The grant of Armorial Bearings to a local authority is a Royal Privilege. Spelthorne's was granted in 1975. The shield is divided by a straight line across the middle. In the lower half, alternate waves of blue and white represent the Thames. Against them stands a thorn tree recalling the famous tree which gave its name to the ancient 'Hundred' (or Borough) of Spelthorne.

Spanning the waves is Staines Bridge and behind it rises the sun from Sunbury's crest against a background of blue. As well as referring to Sunbury, the sun suggests the dawn of a new civic life for Spelthorne.

The motto: Ad Solem Prospicimus - literally - 'we look towards the sun' implies facing the daylight of a new civic era for Spelthorne Borough Council.

The crest is upon two crossed swords on the top of which a swan represents the River Thames, an important factor in the life of the Borough. While the swords suggest two former Middlesex authorities, the new Borough in Surrey is symbolised by two sprigs of oak and two acorns from the Surrey County Council Arms.
