It is south of its parent parish of Orpington, lies about 100 metres above sea level and beyond London's urban sprawl.

[1] It is a small village, consisting of a main road (Rushmore Hill) on which is situated a school, a village shop (the post office was closed as part of the widespread branch closures of June 2008) and the Bulls Head pub, two small churches and a few side roads.

A "bottom" in this context means a valley or hollow, and the Pratts were a noble family once seated in the area.

Sue Short has written a book about the history of the village titled Pratts Bottom: A Journey Through Life.
