Uxbridge is a suburban town in west London and the administrative headquarters of the London Borough of Hillingdon. Situated 15.4 miles (24.8 km) west-northwest of Charing Cross, it is one of the major metropolitan centres identified in the London Plan. Uxbridge formed part of the parish of Hillingdon in the county of Middlesex, and was a significant local commercial centre from an early time. As part of the suburban growth of London in the 20th century it expanded and increased in population, becoming a municipal borough in 1955, and has formed part of Greater London since 1965.

West London is the western part of London, England, north of the River Thames, west of the City of London, and extending to the Greater London boundary.
