In line with the exit of the United Kingdom from the European Union, the European Region layer has been frozen as of 01 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 01 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.
  (Amended Wales Act(2006) with changed constituency name references)
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.
Each bulleted list summarises the County, Unitary Authority and Metropolitan District boundaries within each Government Office Region.

Previously, the reference to boroughs has not been included in the Boundary-Line product. In striving to improve the product and at the request of the end users, the inclusion of a reference to the boroughs will enable users to search within their GIS and locate them more easily. 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.

This release note provides information about the October 2025 release of Boundary-Line.
In line with the exit of the United Kingdom from the European Union, the European Region layer has been frozen as of 01 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 01 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.
Vector tiles (MBTiles) format has been available for Boundary-Line since 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:
  (Amended Wales Act(2006) with changed constituency name references)
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.
Each bulleted list summarises the County, Unitary Authority and Metropolitan District boundaries within each Government Office Region.

This release note provides information about the May 2025 release of Boundary-Line.
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:
 (Amended Wales Act(2006) with changed constituency name references)
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.
Each table summarises the County, Unitary Authority and Metropolitan District boundaries within each Government Office Region.

Previously, the reference to boroughs has not been included in the Boundary-Line product. In striving to improve the product and at the request of the end users, the inclusion of a reference to the boroughs will enable users to search within their GIS and locate them more easily. 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.
Information published by the Office for National Statistics (ONS) identifies the European classification system called NUTS (Nomenclature of Units for Territorial Statistics). This information provides a breakdown of UK regions and countries, allowing for a comparable view of economic activity across the European Union.
NUTS1 – English Government Office Regions, Wales, Scotland and Northern Ireland.
NUTS2 – 37 areas, mainly groups of counties and unitary authorities.
NUTS3 – 133 areas, principally individual counties and unitary authorities.
