Great Burstead was an
ancient parish. It became part of the
Billericay Urban District in 1934 and was abolished in 1937 when all the parishes in that district were merged into a single parish called Billericay. The urban district was renamed Basildon in 1955 and was reformed to become the modern Basildon district in 1974, at which point the district also became an
unparished area. The modern parish of Great Burstead and South Green was formed on 1 September 1996 from part of the unparished area. The new parish covers a smaller area than the pre-1937 parish of Great Burstead, which had also included the town of
Billericay. ==Governance==
