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. 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 opted to combine Cheshire with Merseyside as a sub-region of the North West Region, with the creation of two cross-county boundary constituencies of Ellesmere Port and Bromborough, and Widnes and Halewood, which avoided the need for a constituency which spans the River Mersey. As a consequence, there are significant changes in the west of the county. The town of Neston would be moved from Ellesmere Port and Neston to City of Chester, resulting in these constituencies being replaced by Chester North and Neston, and Ellesmere Port and Bromborough respectively. Halton would be abolished, with Widnes being included in the new constituency of Widnes and Halewood, and Runcorn in the new constituency of Runcorn and Helsby. Eddisbury and Weaver Vale would both be abolished, being replaced by Chester South and Eddisbury, and Mid Cheshire.

The following constituencies were proposed and adopted:

 * Chester South and Eddisbury (part)

 * Runcorn and Helsby (part)
 * Widnes and Halewood (part also in the Merseyside borough of Knowsley)

2010
Following the Fifth Periodic Review of Westminster Constituencies by the Boundary Commission for England, the existing 11 constituencies were retained with changes to realign constituency boundaries with the boundaries of current local government wards, and to reduce the electoral disparity between constituencies. These changes were implemented at the 2010 United Kingdom general election.
