This is the latest in a 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 describe a new open address dataset released by Warwick District 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 Warwick District Council
The latest council to release its Council Tax address list is Warwick District Council in the West Midlands region of England. The Council disclosed all of the requested information without difficulties and granted permission for re-use under the terms of the Open Government Licence.
You can download my correspondence with the Council: CT_address_list_Warwick_24297_[NO_DATA_correspondence_only].zip (0.51 MB).
Thanks to Council staff for facilitating the disclosure and open licensing of this data.
Why you can't have the dataset – or maybe you can?
I am not publishing Warwick District Council's address dataset here, due to the non-specific but lingering risk of further unsubstantiated claims of infringement from Ordnance Survey and GeoPlace LLP. You can read more about that issue in my recent blog post.
However, there is nothing to stop you asking the Council directly for a copy of the data file. For tips on submitting access to information and re-use requests see this other blog post. My requests to Warwick District Council were submitted on 1 May 2026 and the Council's reference is 24297.
More about Warwick District Council's address dataset
Warwick District Council has disclosed its Council Tax address dataset to me in the form of an Excel workbook 'CTax Forecast Recovery Detail 2026 07-05-2026 20-00-12.xlsx' that contains 71,395 records. Each record includes the full address (split into five fields), postcode, local property reference, Unique Property Reference Number (UPRN), and Council Tax valuation band, for a domestic property in the Warwick District Council area.
The dataset is tidy and appears to be well-maintained. Based on the file name the data was produced from Council systems on 7 May 2026.
UPRNs are missing for 62 of the 71,395 records in the list. UPRN values in two records are obviously wrong but the likely correct UPRNs can be inferred from UPRNs given for neighbouring properties. Following those corrections, all UPRNs match to records in the May 2026 release of Ordnance Survey's Ordnance Survey's OS Open UPRN product. This means that almost all of the property records in the dataset can be geocoded for mapping and geographic analysis of domestic properties in the Warwick District Council area.
