This release note provides information about the April 2024 release of the AddressBase products. These products were released to customers on 05 April 2024.
| Product | Full Supply Record Count[1] | Change-Only Update Record Count[2] |
|---|---|---|
There is a difference in product counts between taking a national Managed Great Britain Set (MGBS) and a national Area of Interest (AOI). This is because the two supplies use different selection criteria. The differences are shown in the following table, allowing for you to validate your data holdings once you have loaded the latest release of AddressBase data.
The national AOI refers to the pre-selection GB polygon from our download store. Therefore, if you have drawn your own AOI, the count will vary.
If you are unsure of your supply type, please check this with your OS Relationship Manager.
If you receive a Change-Only Update (COU) supply for your AddressBase product, you will receive Insert, Update and Delete records within the supplied file. The following tables detail the numbers of these records which can be expected in an MGBS supply,and also how many tiles are affected if you take your supply as Changed Chunks.
The following information relates to the currency of the source data used in the creation of Epoch 109:
Affected output formats: CSV and GML
There are 5 021 Unique Property Reference Numbers (UPRNs) which reference a Parent UPRN which cannot be found in the product. This is because the Parent UPRN is either provisional or historic and is not matched to the Royal Mail Postcode Address File (PAF) or Valuation Office Agency (VOA) record, meaning that it is not included in the AddressBase Plus product as per the existing background logic rules.
There are 254 records with a sao_start_no or sao_text that have no Parent UPRN in the product. This is because the Parent UPRN is a historical record which is included as part of the logic for record inclusion in the AddressBase Plus product.
The match rates for Council Tax and Non-Domestic Rates for Epoch 109 are detailed as follows based on Valuation Office Agency (VOA) records up to 26 February 2024. The match rate is applicable to the AddressBase Premium product.
Work is being undertaken to improve the classifications of records within the AddressBase products. This work has resulted in 47 161 more tertiary classifications present in Epoch 109 compared to Epoch 108. Indeed, 88.77% of these tertiary classification improvements are against residential codes.
The following graph shows the number of Postcode Address File (PAF) matched records in AddressBase by epoch:
Notification of Epoch 109’s Improvement in Historic BLPU State Code Completeness and Large Release Size
This release includes an enhancement in the clarity and consistency of life cycle representation within product.
A conformance improvement has been delivered for BLPU State attribute for records where the BLPU Logical Status was 8 (historic) and BLPU State was null, for increased completeness BLPU State Code has been populated with value 4 (no longer existing) and date stamped for the change applied.
The BLPU state identifies the current life cycle stage of a property (or object) and is additional to the mandatory LOGICAL_ STATUS field.
The BLPU code is an optional attribute for Local Authority Custodians to complete and therefore this attribute may be NULL in product.
An improvement to the completeness of the BLPU State Code was identified as a quality enhancement for life cycle information as values for BLPU state code 4 can be accurately inferred from a Logical Status of 8. This enhancement allows the data to be interpreted more easily by removing conflict between addresses with a historic logical status and no BLPU state.
All nations within GB and the Islands product regions will benefit from this improvement, as such it impacts approximately 1.2 million records for a full supply.
This quality improvement means a larger than usual supply of COUs.
The next release of AddressBase products, Epoch 110, is scheduled for 16th May 2024.
These counts are based on a Managed Great Britain Set (MGBS). If you have ordered your national coverage via the online ordering system using a polygon outline, then your counts may differ.
Change-Only Updates are not available for the OS Open UPRN product.

It is important that COUs are processed with Deletes first, then Inserts and Updates; this is to ensure that updates are applied in the correct order. Guidance on this can be found in the Working with COU data page in the Getting Started Guides for AddressBase, AddressBase Plus and AddressBase Plus Islands.
