Parliamentary Boundary Review 2023

New Parliamentary Consituency Boundaries

The new parliamentary constituency boundaries proposed under the ‘2023 Review’ were approved on 15 November and come into force from 29 November 2023. They will take from the next General Parliamentary election.

What is the 2023 Review

Parliament asked the Boundary Commission for England to review the Parliamentary constituency boundaries to rebalance the number of electors in each constituency. Due to population changes since the last review, the number of electors in some constituencies was much higher than in others. The 2023 Boundary Review ensured each MP represents roughly the same number of electors (between 69,724 and 77,062). 

The number of constituencies in England also increased from 533 to 543. 

More information about the 2023 Review can be found by visiting the Boundary Comission for England page on the website.

Some FAQs

Will the changes affect my local council services, bin collections or schools, for example?

No. The boundary changes only relate to Parliamentary constituencies (the area an MP is elected to represent in Parliament). Services and council tax in your local area are set by your local authority and this review does not change local authority boundaries.

Who conducts the review?

The Boundary Commission for England has carried out the 2023 review. There is a Boundary Commission for each of the four parts of the UK who each determine the constituency boundaries in their area. 

A statutory formula is applied to the electorate figures to share out the 650 constituencies across the four countries of the UK and all regions.
