What is the National Land and Property Gazetteer?

The National Land and Property Gazetteer (NLPG) covers the whole of England and Wales and contains more than 30 million residential, business and non-mailing addresses. It is a comprehensive and continually updated database, created by those with local knowledge in each local authority, the body with legal responsibility for street naming and numbering of property.

The NLPG uses the rigorous BS7666 standard (Parts 1 and 2) to ensure data format consistency across the country. Each record has a unique property reference number (UPRN) which provides a reference key to join related address records across different datasets.

Because of their legal responsibilities, local authorities are the originators of address data throughout the 'property lifecycle', obtained through their activities such as planning applications, building and environmental control, licensing, the electoral roll, council tax and non-domestic rates. The NLPG thus holds far more than just mailing addresses. It includes separate units of properties in multiple occupation (like flats, retail units or office blocks), land, buildings within complexes (such as hospitals, schools or universities) and other structures (such as churches, scout huts and war memorials) and the history of all changes to those properties. There are more than 4 million such objects in the NLPG.
