Carshalton Urban District

From the Wikipedia page :

Carshalton was a local government district in north east Surrey from 1883 to 1965 around the town of Carshalton.

The parish of Carshalton adopted the Local Government Act 1858 in 1883 and a local board was formed to govern the town. The Local Government Act 1894 reconstituted the area as an urban district, and an elected urban district council replaced the local board.[1] In 1933 the boundaries of the district were altered after the abolition of Epsom Rural District.[2]

The district was abolished in 1965 by the London Government Act 1963 and the former area was transferred to Greater London to be combined with that of other districts to form the present-day London Borough of Sutton.
