This release note provides information about the May 2024 release of the AddressBase products. These products were released to customers on 16 May 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 110:
Affected output formats: CSV and GML
There are 5 420 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 240 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 110 are detailed as follows based on Valuation Office Agency (VOA) records up to 08 April 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 38 568 more tertiary classifications present in Epoch 110 compared to Epoch 109. Indeed, 88.75% 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:
The next release of AddressBase products, Epoch 111, is scheduled for 27th June 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.
