AddressBase Premium is the most comprehensive dataset of streets, properties and their addresses for Great Britain. Updated on a six-weekly cycle, the AddressBase Premium dataset is derived from local government’s NLPG (National Land and Property Gazetteer) as created and maintained by GeoPlace, Ordnance Survey’s OS MasterMap® Address Layer 2 and the Royal Mail’s PAF (Postcode Address File). Adhering to British Standard for addressing BS7666, every property includes its Unique Property Reference Number (UPRN) and for every street its Unique Street Reference Number (USRN). It contains information relating to the full life cycle of a property including its provisional, historic and alternate addresses. Every street has its start and end coordinates as well as regional language description if appropriate, for example Welsh street name. In addition, every property or street is given geographical coordinates, enabling the data to be used within a GIS.
An area of land in uniform property rights or, in the absence of such ownership evidence or where required for administration purposes, inferred from physical features, occupation or use.
BS7666 is a British Standard that sets out the guidelines upon which the Local Land and Property Gazetteers (LLPG) and Local Street Gazetteers (LSG) are built. It sets out the standards on how to record Basic Land and Property Units (BLPUs), using the Unique Property Reference Number (UPRN), grid co-ordinates and one or more Land Property Identifiers (LPIs).

This is the file that contains all changes to streets and properties in AddressBase Premium. This includes new properties and streets, changes to existing properties and streets, plus properties and streets that no longer exist. This is currently released every six weeks.
This is the application of scripts to help correct or improve your streets and property data.
This is the British Standard for transferring street and property data as a text file. This enables data to be passed between systems in a consistent and structured format and underpins the Local Land and Property Gazetteer (LLPG) and Local Street Gazetteer (LSG).
Within the Local Street Gazetteer (LSG) and National Street Gazetteer (NSG), an Elementary Street Unit (ESU) is a record to spatially define a street between nodes and / or junctions.
A gazetteer is a register of geographical information concerning places and locations, often used in conjunction with maps. Modern gazetteers come in a wide variety of formats, covering hugely different subject matters and are used throughout government and industry. Most modern gazetteers will be stored digitally on computers and will often include the ability to see the data spatially via digital mapping technology.
These days, the term gazetteer has become synonymous with the National Land and Property Gazetteer (NLPG) and the National Street Gazetteer (NSG).
We provide software solutions for local government to create and maintain their Local Land and Property Gazetteer and Local Streets Gazetteer. We also enable emergency services, energy and water utilities and other companies to manage and share AddressBase Premium through the gazetteer Bluelight.
A Land and Property Identifier (LPI) is the address of a Basic Land and Property Unit (BLPU) in a standard format that uniquely identifies the BLPU in relation to a street as defined in the National Street Gazetteer (NSG). The principal components of the LPI are the Unique Property Reference Number (UPRN), Unique Street Reference Number (USRN), the building name or number, and potentially floor number.
The Local Land and Property Gazetteer (LLPG) is the collection of address and location data created by a local authority. This conforms to British Standard BS7666, using the UPRN and geo coordinates to provide one true, current address.
We provide local authorities with a software solution to create, maintain and share their LLPG data.
The Local Street Gazetteer (LSG) is a database of all street information. Each LSG is compiled by one of the 172 Highway Authorities in England and Wales, and will feature such information as the USRN, the street name, location, type and length.
We provide local authorities with a software solution to create, maintain and share their LSG data.
The National Land and Property Gazetteer (NLPG) is a database containing over 32 million address records covering the whole of England and Wales. It is the amalgamation of all the BS7666 compliant addresses held by local authorities that have been compiled within their individual Local Land and Property Gazetteers (LLPG). The NLGP is then used by Ordnance Survey to produce AddressBase Premium.
This is the amalgamation of all of the Local Street Gazetteers (LSGs) in England and Wales. As with the National Land and Property Gazetteer (NLPG), Ordnance Survey use this data to produce AddressBase Premium.
This is a twelve digit number assigned to every unit of land and property recorded by local government as required by their statutory obligation to record all changes in property details. Each local council will submit their address register (including the UPRN) to GeoPlace who collate the data into a national dataset referred to as AddressBase.
We provide software solutions for local government to create and maintain their address register and we also provide organisations such as the emergency services and energy and water utility companies, with the necessary software to use AddressBase Premium data.

Similar to the UPRN, the USRN identifies every street recorded by local government. We provide software solutions for local government to create and maintain their street register and we also provide organisations such as the emergency services and energy and water utility companies, with the necessary software to use the national street dataset through AddressBase Premium.
This is the integration of our solutions with other corporate operational systems, such as planning, revenue and benefits or command and control.
A Web map service (WMS) is a standard protocol that describes how to serve any georeferenced map images over the internet, which is usually generated by a map server that uses data from a geographic information system database or gazetteer. The protocol standard was developed by the Open Geospatial Consortium (OGC) and first published in 1999. WMS provides a simple way of requesting geo-registered map images using an HTTP interface.
