Review of Parliamentary constituency boundaries in England

The Boundary Commission for England (BCE) is required by Parliament to complete an independent and impartial review of all constituencies in England. This is to rebalance the number of electors in each constituency and make sure each MP represents roughly the same number of electors (between 69,724 and 77,062).

The 2023 Boundary Review also requires that the number of constituencies in England increases from 533 to 543.

The Commission is holding a secondary consultation on its initial proposals for new constituencies, which takes place from 22 February to 4 April 2022. During the consultation, public hearings will be held across the country to allow members of the public to provide their views in person.

Constituencies are changing. You can have your say now either:

  • via the Boundary Commission for England website
  • by email
  • by letter
  • at a public hearing in your region

How proposals for new constituencies are developed

We must keep to the rules set by Parliament about how many constituencies there are and the number of electors to each MP. We also take into account existing boundaries, local geography, and local ties. We know that local knowledge can help improve our proposals, and have invited the public to participate in our secondary consultation. We will take into account every response when deciding on any changes to our initial proposals.

Review will not favour one political party

The Boundary Commission for England is independent and impartial and will not take into account patterns of voting or the results of elections when reviewing constituency boundaries. Political parties’ views on where boundaries should be do not have any more weight than those of members of the public.

Changes will not affect local council services

Bin collections, schools, services and council tax in your local area are set by your local authority and this review does not change local authority boundaries. The boundary changes only relate to parliamentary constituencies (the area an MP is elected to represent in Parliament).

Timeline for proposed changes

Every response received during the first and secondary consultations will be analysed. If our proposals change, we will publish our recommendations and hold a further public consultation. Our final recommendations will be submitted to Parliament by 1 July 2023, and the new constituencies will take effect at the next General Election after that date.

Names of constituencies may change after review

Generally, the more a constituency has changed, the more likely it is that the BCE will recommend a change of name. The Commission welcomes views on the naming of proposed constituencies during the consultation.
