Warley is a suburb of Brentwood in Essex, situated to the south of the town. It was notable for being home to the British headquarters of Ford Motor Company prior to their office closure.
It is also home to a development of houses situated around and near the former site of Warley Hospital (a psychiatric hospital), called Clements Park. The development includes a range of house styles modelled around local themes, such as the former water tower that supplied the local area. In 2015 the former site of all the buildings and their architectural features of Warley Hospital was sensitively restored creating high specification homes which secured the heritage asset which was once on the heritage at risk register, known as The Galleries.
There was also another prominent psychiatric hospital in Warley for over 150 years, known as Mascalls Park Mental Hospital, although its operations were moved to Goodmayes Hospital in early 2011.There is a Borough of Brentwood council ward by the name Warley, which takes in Great Warley, Little Warley, Childerditch and the Woodman Road/Hartswood area of Brentwood. Traditionally it has been a Liberal Democrat-Conservative marginal, which in 2007 elected the youngest councillor in Britain, at eighteen years of age. It has in recent years elected three Liberal Democrat and one Conservative councillor.
