Parliamentary Boundary Changes

The Boundary Commission for England (BCE) has concluded the 2023 review of all Parliamentary constituencies in England to rebalance the number of electors in each constituency with the aim of improving local representation. These new constituencies have now taken effect, and were first used for the 2024 UK Parliamentary General election.

More about the review

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.
