It is a suburban development situated 13.6 miles (21.8 km) east of Charing Cross. The area is a relatively recent addition, compared with the more mature suburbs in Havering. It was built on open farmland and the former site of RAF Hornchurch. The name South Hornchurch is not an old one, it was devised at the time of the development.Mills, A., Dictionary of London Place Names, (2001) From 1926 to 1965 the area was part of Hornchurch Urban District.
