Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England increased Essex's representation from 17 to 18 MPs, with the creation of the constituency of Witham. This had a significant impact on the boundaries of the majority of the existing constituencies and also resulted in several name changes.

See 2023 Periodic Review of Westminster constituencies for further details.

Following the abandonment of the Sixth Periodic Review (the 2018 review), the Boundary Commission for England formally launched the 2023 Review on 5 January 2021.^[3] Initial proposals were published on 8 June 2021 and, following two periods of public consultation, revised proposals were published on 8 November 2022. The final proposals were published on 28 June 2023.

The commission has proposed retaining the current number of constituencies in Essex, as detailed below, with minor boundary changes to reflect changes to electoral wards within the county and to bring the electorates within the statutory range. It is proposed that Southend West be renamed Southend West and Leigh, and Rochford and Southend East renamed Southend East and Rochford to acknowledge that Southend-on-Sea had achieved city status during the course of the review.^[4] In addition, Saffron Walden will be abolished and replaced with North West Essex.

The proposed constituencies are a follows: ^[5][6]
