2023 parliamentary constituency boundary review

Constituency boundaries are changing, and it’s your final chance to help shape the new map.

Why the review is taking pace

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 has listened to the feedback sent in from the public, and have 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.

Have your say

A final public consultation is open now until 5 December and is the last chance to provide your views on new constituency boundaries. The Boundary Commission for England has invited the public to visit the BCE reviews website and comment on the proposals via the website, email or letter.

Hard copies of the proposals are available to view at public places of deposit listed on the BCE website. You can give your feedback on anything from where the proposed electoral boundaries are, to the suggestions for new constituency names.

To tell the Commission whether the new proposals for constituencies best represent your local community, visit the BCE website. Have your say before 5 December.
