June 2024
This release note provides information about the June 2024 release of Boundary-Line.
Customer Information
Due to the recent coastline improvements that have been made, there are additional polygon vertices present in this release. If this causes any issues for you when loading the data, please let us know.
An error was found in the May 2024 v.1 release of the Boundary-Line product. The error meant that expected changes on the ward layer for Worcester City were not present in that release. This has since been corrected and is now present in the Boundary-Line product.
In the previous May release, due to an internal update to a system, the Unit ID were all been changed. These IDs have now been restored.
The attribute order found in the Shapefile format of this release have been updated to meet the attribute order stated in the product spec.
Product Enhancements
In line with the exit of the United Kingdom from the European Union, the European Region layer has been frozen as of 1 April 2021 (no edits have been made to the European Region extents since 31 December 2020, but there were some minor coastline edits up to 1 April 2021). This frozen layer is available as a supplementary Historical European Region layer within Boundary-Line.
For the purposes of Boundary Review, the extents of the European Regions in England have been retained in the Boundary-Line product and will be maintained as an English Region layer.
For customers who used the European Region layer to represent a national extent for Scotland and Wales, a new Country Region layer is available as a supplementary layer in Boundary-Line. This will be a maintained layer and represents the national extents of England, Scotland and Wales.
Boundary-Line is now released in vector tile (MBTiles) format as of October 2021.
Boundary-Line has updated the legal name of the National Assembly for Wales to Senedd Cymru/the Welsh Parliament.
The relevant legislation and Statutory Instruments (SIs) can be found here:
Legislation 1
Legislation 2 (Amended Wales Act(2006) with changed constituency name references)
Data Issues
The Global_Polygon_ID attribute is not present in the vector tile format of Boundary-Line at this release. All other formats are unaffected by this issue. This will be rectified for the subsequent release of Boundary-Line.
New Westminster Constituency Boundaries
The Westminster Constituency Boundaries created by the National Boundary Commissions were based on the Ordnance Survey Boundary-Line product data in place on 1st December 2020. As this does not take account of any subsequent amendments to this product, there will be some variation between the boundaries displayed in the Boundary Line product and the Final Recommendations:
The Ordnance Survey has captured the Westminster Constituency features based on the Boundary-Line product electoral boundaries from the latest release and has corrected any minor errors to the Boundary Commission’s final recommendations. The types of corrections made would typically be as a result of administration changes due to electoral reviews, or geographical changes such as to coastline or rivers.
The Ordnance Survey Westminster Constituency Boundary between Stoke-on-Trent Central and Stoke on Trent North Constituencies has been amended at 26-45 Forest Edge, Sneyd Street Stoke-on Trent, ST6 2PY, and does not follow the boundary between the Moorcroft and Sneyd Green and Birches Head and Northwood electoral Wards. The Ordnance Survey Westminster Constituency boundary has been amended at this location and is consistent with the constituency boundary created by the Boundary Commission for England, this has been carried out to ensure that the properties indicated are located in the correct Westminster Constituency.
Ordnance Survey Westminster Constituency boundaries and Government Statistic Service (GSS) codes for the Ayr, Carrick and Cumnock / Berwickshire, Roxburgh and Selkirk / Central Ayrshire / Kilmarnock and Loudoun / West Aberdeenshire and Kincardine constituencies were amended following consultation with the Boundary Commission for Scotland and Government of Scotland.
The boundaries of these Westminster constituencies have been amended to ensure the consistency with local electoral boundaries, and as no electors were involved in any changes this did not affect the electoral totals. To indicate that these constituencies had been amended and were no longer the same as the current constituencies (dated 2007), and to prevent any confusion, new GSS codes were allocated to provide a unique identifier for the new parliamentary constituencies.

Changes not incorporated into the June 2024 Boundary-Line update
Residual Statutory Instruments (SIs) and non-SIs Boundary-Line only represents the boundaries that are currently operational; future dated or unsigned SIs will not be included. This ensures that the boundary information currency is correct at the time of the dataset release. SIs that are operational in May and or October but signed off too late for inclusion in the May or October products would be included in the next suitable release.

This addition was introduced in October 2006.
These additions only apply to England and affect the districts that have been granted Charters of Incorporation (CoI), unitary authorities that have been created from previous districts with CoI, and metropolitan districts that have borough status. The tables below identify where (B) has been added to the file name and (B) to the boundary data. This addition does not affect the structure or specification of the product and will not impact on your GIS or translation software.
