Polling districts in Boundary-Line

This Freedom of Information request asks for the source for polling districts data in Boundary-Line.

Request for information - Ref No: FOI18855


Thank you for your email of 29 August 2018, requesting information from Ordnance Survey in accordance with the Freedom of Information Act (FOIA) 2000, as set out in the extract below:

Contained in your Boundary-Line product are shapefiles of English polling districts and their Welsh equivalent, community wards.

I am writing to request a complete list of the bodies, government or otherwise, your agency contacted to obtain these shapefiles.

Our response

I confirm that Ordnance Survey does not hold the information you have requested. 

The information you requested was sourced by third parties and not by Ordnance Survey, as explained below, under the duty to provide information and assistance in accordance with section 16 of the FOIA.

In relation to the polling district layer in Boundary-Line, this shows only the English polling districts and was originally created as a supplementary file in 2015/16, commissioned by the Boundary Commission for England, to assist with their creation of new parliamentary constituencies based on the associated warding pattern at a single point in time (2015 general election). The Boundary Commission for England sourced all the data for Ordnance Survey, any corrections to the state as at 2015 as advised by the local authorities, must go via the Boundary Commission for England and not directly to Ordnance Survey.  Therefore, please contact the Boundary Commission for England, for the requested information in relation to English Polling Districts.    

Please note due to the uptake of the Polling districts layer in Boundary-Line, Ordnance Survey ceased making any updates to this information in 2016 and it will not be updated for the foreseeable future.

The Welsh Community Wards were released as a separate supplementary data set and the information was sourced by the Boundary Commission for Wales. Please therefore contact the Boundary Commission for Wales.  To clarify the Welsh Community Wards are not shown in the Polling District layer.

For further information please go to our Boundary-Line support pages on our website.

Please note the information on the above web page is due to be updated shortly and will reflect the situation that updates to the Polling districts layer ceased in 2016, as stated above.
