The site of Upton Court Park seems to have been acquired by the Corporation of Slough sometime between 1930 and 1937 and contained 147 acres of field. However, by 1963 this expanded to 180 acres.

Since the site was converted into a park, it has offered the people of Slough many sporting facilities. It has provided a long-term home for Slough Rugby Club, and during the 1960s it contained a temporary go-carting track, which is thought to have been the first provided by a local authority.

Today the list of facilities includes a jogging trail with exercise equipment, a motorcycle scrambling club, a BMX track where events are held, an area for model aeroplane flying clubs and a model car racing club area.

Upton Court Park has been the venue for many of Slough's festivals and cultural events, such as the 'Grand Country Fair' in 1977, celebrations for the 50th anniversary of the creation of India and Pakistan and the 2003 Youth Festival. 'Slough Bonfire' in November is still held every year.
