Formally named as the Mid or Chelmsford Division of Essex, the seat was one of eight single-member divisions of Essex (later classified as county constituencies) created by the Redistribution of Seats Act 1885, replacing the three two member divisions of East, South and West Essex. Historically, the constituency was on occasion referred to as 'Mid Essex', especially in the early part of the 20th Century.[3] It continued in existence, gradually being reduced in geographic size as additional seats were created in Essex, until it was briefly abolished for the 1997 general election following the Fourth Periodic Review of Westminster Constituencies and replaced by parts of two new constituencies: Maldon and East Chelmsford and West Chelmsford. It was re-established for the 2010 general election as a Borough Constituency by the Fifth Periodic Review.
During its latter years, the old seat was narrowly won by a Conservative over strong Liberal Democrat performances, including their predecessor party the Liberal Party. At its first contest in 2010, the re-established seat was closely fought by the Conservatives and the Liberal Democrats, who finished less than 10% apart, with Conservative candidate Simon Burns (the former MP for West Chelmsford) being elected. Labour polled 11%, despite having been only around 100 votes behind the Liberal Democrats in West Chelmsford in 2005, and even taking second place in 2001. Labour regained second place for the 2015 and 2017 elections but were overtaken again by the Liberal Democrats in 2019.
