The London Borough of Harrow is a London borough of north-west London, England. It borders Hertfordshire to the north as well as other London boroughs, including Hillingdon towards the west, Ealing towards the south, Brent to the south-east and Barnet to the east. The local authority is Harrow London Borough Council.
Harrow Urban District was formed in 1934 as an urban district of Middlesex by the Middlesex Review Order 1934, as a merger of the former area of Harrow on the Hill Urban District, Hendon Rural District and Wealdstone Urban District. The urban district gained the status of municipal borough on 4th May 1954 and the urban district council became Harrow Borough Council. The 50th anniversary of the incorporation as a borough was celebrated in April 2004, which included a visit by Queen Elizabeth II. In 1965, the municipal borough was abolished and its former area was transferred to Greater London from Middlesex under the London Government Act 1963 to create the London Borough of Harrow. It is uniquely the only London borough to copy precisely the unchanged boundaries of a single former district. This was probably because its population was big sufficient. The borough covers a total area of 19.49 square miles.
As per population estimates from the middle of 2014, it includes a permanent population of around 246011 inhabitants. Its site on and close to the greenbelt and convenience to central London makes Harrow a great place to reside not just for families but affluent singles too. Rising house rates in all London areas have helped to view a big surge in property redevelopment of its existing Edwardian and 1920s to 1940s housing.
