This is the latest in an occasional series of blog posts about the campaign for open address data in the UK. Previous posts are listed at the bottom.
In this post, I make available a new open address dataset released by Wigan Council.
Background
As described in previous posts, I have recently been requesting Council Tax address datasets from a number of local authorities in England, and asking for permission to re-use the data under the terms of the Open Government Licence.
I have created a landing page on my Datadaptive site with download links and other information about the Council Tax address datasets released as open data so far:
Release from Wigan Council
The latest council to release its Council Tax address list is Wigan Council in North West England. The Council disclosed all of the requested data under the FOI Act without difficulties and confirmed permission for re-use of the disclosed information under the terms of the Open Government Licence (OGL).
You can download my correspondence with the Council, including the information as disclosed: CT_address_list_Wigan_Council_18954.zip (3.44 MB).
Thanks to Wigan Council's Legal, Governance and Elections Division for facilitating the disclosure and open licensing of this data.
Geocoded open version of Wigan Council address dataset
I have created a geocoded version of the Wigan Council address dataset, which you can also download: WIGAN_CTBANDS_ONSUD_202511.zip (15.3 MB).
This dataset contains information collated from the underlying Council dataset, other than the postcodes. Geographic coordinates and postcodes have been appended from the latest edition of the ONS UPRN Directory (November 2025). I have prepared the data in CSV and GeoJSON formats, suitable for re-use under the terms of the Open Government Licence (OGL). Please see the enclosed ReadMe file for information on attribution and additional technical details.
