Passionate about data

Driving improvement, excellence and innovation through data

GeoPlace is a Limited Liability Partnership jointly owned by the Local Government Association (LGA) and Ordnance Survey.  We are a world class expert in address and street information management.

We were set up as a result of a government call for a standard index of addresses to bring together existing creators and suppliers of addressing data to one central place to build a single, definitive address database. The resulting data is made widely available through Ordnance Survey which develops the range of AddressBase® products from the National Address Gazetteer.

Today, GeoPlace maintains a national scale information infrastructure that supports the needs of both the public sector and a wider commercial market.

We were formed in 2011 by joining together an established public sector organisation and a skilled private sector organisation. Our expert team demonstrate excellence in data quality; information standards; technical IT skills and relationship management.

 The work we do includes:

  • creating and maintaining data models
  • data cleansing and validation
  • working with a network of local authority officers to balance different stakeholder needs.

Our work relies heavily on close working relationships with every local authority in England and Wales. This relationship has been developed over more than a decade, to build the National Street Gazetteer and the National Address Gazetteer infrastructure. Both of these underpin efficient and effective services, bringing direct service delivery benefits to users.

Through our sponsorship of the Joint Authorities Committee (JAG(UK)), GeoPlace enables the co-ordination of organisations responsible for the roads and streets of the United Kingdom, including government, the Highway Authorities and Utilities Committees, National Traffic Managers Forum and other related bodies for asset or utility network management and other events taking place on the highway.

Working under the  Data Co-operation Agreement,  we have a relationship with every district, county and unitary council in England and Wales to support the creation and ongoing maintenance of the National Address Gazetteer infrastructure and the National Street Gazetteer.

We operate under direction from our Board. Details of the board and our current workplan can be seen at


GeoPlace LLP is incorporated and registered in England and Wales with company number OC359627. The registered office is Explorer House, Adanac Drive, Southampton, SO16 0AS. Our main office is in London.


About the National Address Gazetteer

The National Address Gazetteer infrastructure is the data storage and set of processes bringing together the existing local authority sourced addressing datasets together with Ordnance Survey, Valuation Office Agency and Royal Mail data.

Through agreement between Ordnance Survey and Scotland's Improvement Service, working on behalf of Scottish Local Government, the National Address Gazetteer includes Scottish address data. The National Address Gazetteer is the single source from which the AddressBase products are developed.


About the National Street Gazetteer

The NSG contains definitive information for streets in England and Wales. Primarily it allows local authorities to manage all streetworks carried out by themselves and by statutory undertakers in an efficient manner on the national road network.

It was created to coordinate the process of streetworks in England and Wales, helping to prevent streets being repeatedly dug up over a period of months by different utility companies and local authorities.  It provides a unique referencing system, is embedded in legislation and is fundamental in the processes of managing all streetworks.
