Post 2024 General Election – UK Postcode to Parliamentary Constituencies

Parliamentary constituency boundaries will change at the next UK general election. The four Boundary Commissions for England, Scotland, Wales and Northern Ireland published their final recommendations in late June 2023 following three rounds of public consultation.  We have spent a great deal of time collating the new 2024 UK Election areas by Postcode.

Coverage

The four Boundary Commissions for England, Scotland, Wales and Northern Ireland published their final recommendations in late June 2023 following three rounds of public consultation.

The 2024 Election Postcode lookup data maps the current Postcodes to these forthcoming boundaries

UK Postcodes (circa. 1.9 million) and the Postcode’s associated Parliamentary Constituencies showing the Westminster, Scottish Parliamentary, Northern Ireland, Stormont (NI) Constituencies and the Alternative Constituencies for Welsh Assembly.

In addition, we include a list of circa. 892,441 ‘Retired’ postcodes. To produce this data list, the Parliamentary Constituency Code and Constituency Name are geographically matched to each Postcode.

Most constituencies will have new boundaries. Overall, just over half of the existing constituencies (332) will be very similar to their closest successor (with over 90% of premises in the same constituency before and after the change).  No changes – 65 seats (one in 10) will have no change to their boundaries, although four of these will have a new name. The remaining 585 seats will have at least some change. Small changes – 40 seats will have only a small change to their boundaries (in some cases affecting only a few premises).

Enlarged constituencies – 76 seats will be enlarged compared with their current boundaries. This means that the new constituency covers all (or almost all) of the current constituency’s area, but also extends to areas that used to be part of different constituencies. These seats would mostly have been too small to meet the minimum electorate threshold in their current form.

Reduced constituencies – 73 seats will be reduced in size compared with their current boundaries. This means that they give up areas to other new constituencies but gain no (or almost no) new areas. These seats would mostly have had electorates higher than the maximum threshold in their current form. An example, Sheffield Central, is shown in the map below.

Abolished constituencies – A constituency is sometimes said to be “abolished” if its area is split between many surrounding constituencies and/or there is no obvious successor. There is no definitive list of abolished constituencies.
