Boundary & Electoral Reviews

The 2023 Review of Parliamentary Constituency Boundaries


A review of Parliamentary Constituencies is taking place to ensure each one has roughly the same number of electors. As part of this process, the number of constituencies in England will increase to 543. The Commission is required by law to make sure that each constituency in England has between 69,724 and 77,062 electors, excluding two 'protected' constituencies for the Isle of Wight. Due to population changes, the number of people registered to vote in some constituencies is much higher than in others.

The 2023 Boundary Review will therefore rebalance the number of electors represented by each MP. It's an important process, and one which requires considerable change to the existing map of constituencies.

Initial Consultation

The Commission has published the responses received from the first consultation which took place in 2021 on their website.  First consultation responses.

Secondary Consultation

The secondary consultation will take place from 22 February to 4 April 2022, and you are invited as members of the public to view and comment on the proposals on the Boundary Commission consultation website or send a letter or email.

Public Hearings

The Boundary Commission will be holding 32 public hearings across the country, where people can tell them their views in person.
