AddressBase Plus is part of the AddressBase Product range​
It has approximately 37 million address records covering England, Wales and Scotland
AddressBase Plus is available in CSV or GML data formats​
It has more properties than AddressBase Core as it includes objects without postal addresses and live records captured by Local Authorities but not matched to Royal Mail PAF data​
Local Land and Property Gazetteer (LLPG) is a database created and managed by Local Authorities where the Unique Property Reference Number (UPRN) is created and assigned to land and property within their district​
​UPRNs can be assigned a hierarchical Parent or Child status if there are multiple UPRNs that share a relationship with each other (E.g. The whole block of flats (Parent UPRN), each flat within the block (Child UPRN) ​
​Each UPRN is linked to a Unique Street Reference Number (USRN) which is held in a different database called the Local Street Gazetteer (LSG)​
​The LSG is managed by the Highway Authority for that area, and they create the USRN ​
​AddressBase Plus includes all Postcode Address File (PAF) addresses matched to a UPRN, additional UPRNs unmatched to a PAF, and non-postal objects, with their tertiary/quaternary level classification type​​
The Postcode Address File (PAF) database is managed by Royal Mail​
​A Unique Delivery Point Reference Number (UDPRN) is created for each PAF and references a specific delivery point​
The PAF has its own Delivery Point Address which may differ from the address held in the LLPG, because it specifically identifies the location in where the property will receive mail ​
AddressBase Plus includes additional UPRN records that share a UDPRN ​
The Valuation Office Agency (VOA) data is for properties that are non-domestic, and pay business rates​
When a business reports to the VOA it gives details such as name of the business, the nature of the business, floorspace of the premises etc.. From these details the ‘Organisation’ data is collected​
The VOA will assign the property on the non-domestic rating list a Special Category code (SCat code) which is a code used by the VOA to classify a property’s business use. There are over 350 SCat codes in use each reference a Sector, and a Sub-sector use classification​
AddressBase Plus has additional data from OS MasterMap Topography layer in it​
E.g. Ponds, Electrical Sub Stations, Post Boxes, Public Telephones​
And OS MasterMap Highways Network, identifying additionally footpaths, and roads to those recorded in the LSG
UPRNs can be created for lots of different reasons. There is no one set trigger, other than there is a need to reference the pin-pointed location. However, the UPRN is a critical component to the planning process, and are most commonly created for this purpose​ during the Outline Planning stage of the image above.
There can be varying data quality across UPRN data because their level of management is dependent on their Local Authority. GeoPlace set certain standards for Local Authorities to follow to ensure a good level of data management, and to achieve consistency​.
A UPRN will be made historic when the building no longer exists. For example if two flats are made in to one. The two existing UPRNs of the flats will be made historic, and a new UPRN given to the new merged property. The historic UPRNs still exist in the dataset as archived records​.
However, in the OS NGD data it is being published at the original, more granular level
