Sulhamstead is a village and civil parish in West Berkshire, England. It occupies an approximate rectangle of land south of the (Old) Bath Road (A4) between Reading, its nearest town and Thatcham. It has several small clusters of homes and woodland covering about a fifth of the land, in the centre and north beside which is Thames Valley Police's main Training Centre at Sulhamstead House. Its main amenities are its Church of England parish church and a shop and visitor centre by the Kennet & Avon Canal.
The name Sulhamstead means 'Narrow Valley Homestead' and was given to the area by the first Saxon settlers. There is supposed to have been a Danish Camp of some sort there during the troubled times just before and during King Alfred's reign.
Sulhamstead House, commonly known as the White House, was the manor house of Sulhamstead Abbots. It was built by Daniel May, son of the Basingstoke brewer, Charles May, in 1744, becoming home to his sister's descendants, the Thoyts family.
The house was largely rebuilt in 1800 for William Thoyts, the High Sheriff of Berkshire. It was the childhood home of his great granddaughter, Berkshire historian and palaeographer, Emma Elizabeth Thoyts (1860-1949). It refurbishment was paid for in 1910 by William G Watson, created a baronet (territorial designation: of Sulhamstead). The baronetcy is extinct.
In 1949, the house became the headquarters of the Berkshire Constabulary. Since their merger into Thames Valley Police, it has functioned as that force's training centre and houses the Thames Valley Police Museum. It is a Grade II listed building.
The Sulhamstead estate is owned by the Astor family.
