My understanding is that you are the authority statutorily responsible for naming and numbering properties and streets within your jurisdiction under the Towns Improvement Clauses Act 1847 and the Public Health Act 1925.

This data forms a critical part of our national infrastructure, enabling economic growth, research, and innovation. Businesses rely on accurate naming and numbering data to serve customers, manage logistics, and make investment decisions. Academic researchers use it to study housing patterns, urban development, and social trends. Local organisations and charities need it to deliver their services to the community. Open access to authoritative naming and numbering data can drive efficiency in the private sector, enable evidence-based policymaking, and foster technological innovation in areas like delivery services and property technology. Given these significant public benefits, there is a clear and strong public interest in ensuring this foundational data is openly available for analysis, verification, and reuse.

Please provide an up-to-date list of all current properties within the Authority’s jurisdiction, in Excel (.xlsx) or CSV (.csv) format. Where the word "assigned" is used, it is referring to what the Authority deems to be the official value for the purposes of administering its naming and numbering duties. Please include the following 9 columns:

1. "Property local authority reference": the reference the Authority uses internally to uniquely identify the property.
2. "Property name": the officially recognised name of the property. Leave blank if no name is assigned.
3. "Property number": the number of the property on its street. For example, "13", "221B" or "18-20". Leave blank if no number is assigned.
4. "Property sub-division name": flat, apartment, unit or suite names/numbers, for example. Leave blank if the property is not a sub-division.
5. "UPRN": the Unique Property Reference Number.
6. "Street local authority reference": the reference the Authority uses internally to uniquely identify the street the property is located on.
7. "Street name": the name of the street the property is located on. For example, "High Street". Leave blank if no name is assigned.
8. "Street number": the number of the street the property is located on, such as "A12" or "B123". Non-standard numbers used internally by the Authority such as "C", "D" and "U" roads are also acceptable, but not required. Leave blank if no number is assigned.
9. "USRN": the Unique Street Reference Number of the street the property is located on.

I am only requesting data assigned as part of the Authority’s statutory naming and numbering duties. I am NOT requesting additional metadata such as property ownership, land use classifications, geographical coordinates, postal addresses or property type.

A number of pieces of this information is already accessible by other means, or exempt as it is commercially sensitive. We have supplied what information we are able to in relation to this request.

The data required to fill columns E,G,H and I of the attached spreadsheet is already freely available as OS Open Data and therefore FOI exempt under Section 21.
OS produce 'OS Open UPRN' which contains UPRNs with their OS NGR co-ordinates.
They also produce 'OS Open USRN' which contains USRNs and their associated geometry.
'OS Open Linked Identifiers' shows which UPRNs are linked to which USRNs.
Also, 'OS Open Roads' shows the name and, if applicable, number of every road.

We do not use property or street "local authority references" other than UPRNs and USRNs so columns A and F are "not held". That only leaves columns B to D. We do not hold records of "uncleansed" address data, therefore we have no way of knowing which property names, numbers and sub-divisions were determined by this council under TICA 1847 and which came from other sources. We have been advised that data contains OS and RM IPRs and is thus exempt under section 43 (and Section 21 where you can go to the OS to obtain).
