Boundary-Line statement

Following a number of queries about our Boundary-Line OS OpenData product, please read our statement.

Boundary-Line is an OS OpenData product which we release under the terms of the Open Government Licence. Our production cycle for Boundary-Line sees us release updates in May and October each year.

The primary purpose of Boundary-Line is to show the current operative administrative and voting boundaries within Great Britain.  New boundaries are determined in accordance with Statutory Instruments and Community Governance Orders, which typically come into effect when elections are held (usually in May).  Our product update cycle for the May release aligns with the dates that the changes to electoral and administrative boundaries become operative.

To maintain and update Boundary-Line, we need to process data received at different times, from many third parties, in differing formats within the production cycle. If we released Boundary-Line data ahead of schedule, the data would not have the benefit of going through the production processes which are in place to ensure that the data is accurate and reflects all of the available changes to the boundaries that we receive from local authorities.
