Motto 'IN COUNSEL IS STABILITY'.
Granted 1st December 1962.

The green background is for the rural character of the district and the acorns are for the forest land there. The wavy blue and white lines represent the River Thames, and in base, the gold horse shoe (or racing plate) recalls Royal Ascot and the Ascot Race Course.
The palings and demi stag refer to Windsor Great Park. The two azalea sprigs show a prolific and almost indigenous plant of the district.
The motto is an appropriate quotation from Bacon's Essays.
