Parliamentary boundary review 2023

Constituencies are changing

The Boundary Commission for England (BCE) has now concluded the 2023 Review of Parliamentary constituencies in England, and submitted its final report and recommendations.

The Government will draft an order containing those recommendations and once approved, the new constituencies will be used for the next General (Parliamentary) election following that date.  Should a by-election be called, the existing constituencies will be used.

The aim of the review was to rebalance the number of electors in each constituency with each constituency having between 69,724 and 77,062 electors, so that each MP represents roughly the same number of electors.

The 2023 Boundary Review also required the number of constituencies in England to increase from 533 to 543.

The final report, recommendations, maps and other information are now available to view on the BCE website 2023 Review[external website].
