This release note provides information about the November 2023 (Epoch 106) release of the AddressBase products. These products were released to customers on 23 November 2023.

| Product | Full Supply Record Count[1] | Change-Only Update Record Count[2] |
|---|---|---|
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.
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 106:
Affected output formats: CSV and GML
There are 7 419 Unique Property Reference Numbers (UPRNs) which reference a Parent UPRN that 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 268 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 products.
The match rates for Council Tax and Non-Domestic Rates for Epoch 106 are detailed as follows based on Valuation Office Agency (VOA) records up to 16 October 2023. 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 55 276 more tertiary classifications present in Epoch 106 compared to Epoch 105. Indeed, 88.8% 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:
We have introduced new tertiary and quaternary classification codes to the AddressBase classification scheme. The new tertiary classification for pharmacies and a number of additional quaternary classifications provides a more granular view for pubs, supermarkets, convenience stores and electric vehicle charging points. This makes these classes easier to filter in AddressBase.
We have also introduced additional classifications for bridges within AddressBase to represent the type of feature the bridge spans over. This helps to facilitate effective decision making for customers who use bridge features.
This change to the classification schema was implemented in Epoch 100, which was published on 30 March 2023. From this date, these new tertiary and quaternary classification codes have been included in AddressBase products.
In our addressing products, we provide information detailing which local authority an address is within. From 01 April 2023, several local authorities reorganised to form new authorities. This means that the local authority code for all addresses within the affected authorities changed from the old authority to the new one, resulting in approximately 1.3 million records being updated. These changes will be seen in product from Epoch 101 onwards. The table below maps the changes:
The next release of AddressBase products, Epoch 107, is scheduled for Friday 05 January 2024.
