2023 Parliamentary Boundary Review

Constituency boundaries are changing. 

The Boundary Commission for England (BCE) is required by Parliament to undertake an independent and impartial review of all constituencies in England, to rebalance the number of electors in each constituency.

Constituency sizes currently vary widely due to population changes since the last boundary review. The new map proposed by the Commission will make sure each constituency has between 69,724 and 77,062 electors so that each MP represents roughly the same number of electors. The 2023 Boundary Review also requires that the number of constituencies in England increases from 533 to 543.

The Commission listened to the feedback sent in from the public and changed nearly half of the initial proposals published last year. The new revised proposals are now available to view via an interactive map on the BCE Reviews website.

The statutory public consultation periods have now closed for this review. The BCE is considering all the responses received in the final consultation in order to develop their final recommendations. They should be ready for publication by 1 July 2023.
