A single board of health for the parishes mentioned was formed in 1875 and a very large civil parish in 1927. The Great West Road was completed in 1925, forming the southern border with Hounslow and the farming and market garden land around the village was snapped up for industry and housing developments. The southern part of Heston up to the Great West Road was previously called 'Sutton' (also known as 'The Deans'), the location of a small hamlet subsequently built up as part of the suburb; this name still appears in some road names and other local features. A Roman Catholic parish church was also built for Heston in the 20th century.
