LLPG / NLPG

The NLPG is a gazetteer database. This means it is more than just a list of addresses.

It is a structured dataset linking not just the preferred address, but also any aliases, such as property number, house names or other descriptions by which the property might also have been known, coupled with additional information such as postcodes. Every entry has geographic coordinates.

 The content of the gazetteers is "time-stamped" and increasingly follows the full life cycle for properties from initial application for planning consent, through development, occupation until eventual demolition. UPRNs can also be allocated to other parcels of land (such as common land) that do not have a formal building or an address. The NLPG is a hub where all the data is brought together in a consistent format. It enables other users of this key data to obtain the information from one source rather than making separate arrangements with each of the 376 Unitary and District Authorities.

The Mapping Services Agreement (the MSA) In 2004, as the NLPG neared completion of the development stage, its ongoing central management was put out to open competitive tender as part of the wider MSA public procurement. The contracts for NLPG and its related project, the National Street Gazetteer (NSG), were won by Intelligent Addressing Limited. Through the MSA, more than 500 local government organisations have directly or indirectly agreed either to contribute or use relevant NLPG and NSG data supporting government's efforts to modernise and improve the delivery of services to the citizen.
