Hounslow is a town in Middlesex which has been absorbed into the urban area of London. There was no parish of Hounslow; it straddled the parishes of Heston and Isleworth, with the boundary going approximately along Hounslow High Street (Heston to the north and Isleworth to the south). In 1894 the Heston and Isleworth Urban District was created, unifying the town under one council, even if the council's title did not contain the name Hounslow. Within Heston and Isleworth Urban District, the two former parishes remained legally separate from each other until 1927, when they were merged to form a single parish of Heston and Isleworth, covering the whole Urban District. Heston and Isleworth Urban District became a Municipal Borough in 1932. In 1965, Heston and Isleworth Municipal Borough was merged with the neighbouring districts of Brentford and Chiswick Municipal Borough and Feltham Urban District. The new authority was named the London Borough of Hounslow - the first time the name Hounslow had been used for an administrative body here, despite it having been one the main towns in the area for many years.
Hounslow is the principal town in the London Borough of Hounslow. It is a suburban district 10.6 miles (17 km) west south-west of Charing Cross. It forms a larger post town in the TW postcode area and is an economic hub within the capital; it has a large shopping centre which adjoins its high street and a large number of restaurants, cafés and small businesses, many of which are associated with product assembly, marketing, telecommunications and London Heathrow Airport, as well as having a minority of workers employed in Central London, by which the town is connected by rail and tube.
