Parliamentary Boundaries Review 2023

Latest News

The final consultation on proposed new parliamentary constituencies closed on 5 December 2022.

 The Boundary Commission for England will review all comments submitted during the final consultation stage before they present their final proposals to Parliament by 1 July 2023. 

What will the 2023 review do?

Parliament has asked the BCE to rebalance the number of electors in each constituency. Due to population changes since the last review, the number of electors in some constituencies is much higher than in others. The 2023 Boundary Review will make sure each MP represents roughly the same number of electors (between 69,724 and 77,062). The number of constituencies in England must also increase from 533 to 543. The new map of constituencies proposed by the Commission therefore has significant changes.

The Review will look to make sure all Parliamentary constituencies have roughly the same number of electors within 5% of the same total. The Review aims to achieve improved electoral balance arrangements so that a constituency contains no less than 69,724 Parliamentary electors, and no more than 77,062 (except two ‘protected’ constituencies for the Isle of Wight).

Changing ward boundaries in North Kesteven

The review uses district wards as building blocks to make constituencies. For the first time in this type of review it will include use of boundaries that were legally ‘made’ by 1 December 2020, even though not yet implemented at a subsequent election. In North Kesteven, the district wards are going to change on 4 May 2023 due to an Electoral Review by the Local Government Boundary Commission for England

The new boundaries will not be taken into account in the 2023 Review as they were not legally made until after the review had started, therefore in the ‘2023 Review’ the current ward boundaries will be used. 

Viewing the Proposals

The ‘Sleaford and North Hykeham Constituency’ is within the East Midlands Region.  As a District, it is proposed that North Kesteven is split between three constituencies of ‘Sleaford and North Hykeham’, ‘Grantham’ and ‘Lincoln’.

Who conducts this review?

The Boundary Commission for England will carry out the 2023 review. There is a Boundary Commission for each of the 4 parts of the UK who will 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.  

What happens next?

The last consultation stage closed on 5 December 2022. The Boundary Commission will look at all the feedback sent in and consider whether any changes should be made to the final proposals for constituency boundaries before the final recommendations are submitted to Parliament by 1 July 2023. The new parliamentary constituencies will take effect at the next General Election thereafter.

Some FAQ's

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.

When will the new constituencies take effect?

When the BCE has decided on its final recommendations for the whole of England, it then drafts and submits a formal written report to the Speaker of the House of Commons and will contain a description of the review in each region, a textual description of all the final recommendations, and a set of maps to illustrate the existing boundaries and those proposed by the final recommendations.

The procedure to subsequently implement new constituencies is the responsibility of the Government.  After the final report from all four Parliamentary Boundary Commissions has been laid by the Speaker, the Government is required to submit to the Privy Council an Order that gives effect to all four Commissions’ recommendations. After the Privy Council approves the Order, the new constituencies take effect at the next General Election. Any by-elections held in the meantime have to be held on the basis of the old (existing) constituencies.

Will the name of my constituency change following the review?

Possibly. As well as looking at where the boundaries of constituencies should be, the BCE will recommend a specific name for each constituency. Generally, the more a constituency has changed, the more likely it is that the BCE will recommend a change of name.
