GeoPlace - Bringing Location to Life

Welcome to GeoPlace, view the video below to find out more about us.

We are a joint venture

The decision to create GeoPlace LLP followed the then Secretary of State for Communities and Local Government’s 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.

As a joint venture between the Local Government Association and Ordnance Survey, this involved the acquisition of Intelligent Addressing Limited. Our creation was approved by the Office of Fair Trading, and we started our work in 2011.

Today, working under the Data Co-operation Agreement, we have a strong and productive relationship with every district, county and unitary council in England and Wales.

Our work focusses on data

We collect the data needed to deliver one of the UK’s most valuable resources – a single, definitive address database that holds millions of pieces of information. To do this, we also set the guidance for and maintain the UK’s National Address Gazetteer infrastructure. Our work involves:

  • Creating and maintaining data models
  • Check the quality of vast quantities of data
  • Cleansing data, making sure it meets high standards
  • Working with many organisations, balancing their needs.

We also provide support services and consultancy that helps businesses, local and central government, and organisations of all kinds to improve the collection and use of spatial data.

Our core datasets are the National Street Gazetteer, available to download directly from us and the National Address Gazetteer, available through Ordnance Survey as the AddressBase® range of products.

GeoPlace is the central source for UK addresses and streets

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

GeoPlace is the central source for UK addresses and streets. We work contractually with all 339 councils in England and Wales which have statutory responsibility for approving and creating addresses and 173 local highways authorities. We manage a central hub of 42.8 million addresses and 1.3 million streets, taking feeds of address and street data from local authorities in England and Wales, central government, Ordnance Survey, Royal Mail and data from Scotland, Northern Ireland, Isle of Man and the Channel Islands via the Improvement Service, Land & Property Services, Isle of Man Government and Digimap respectively.

Through a stringent data quality process, we synchronise and match data against records from several authoritative government property and address databases. Through a validation and assurance process we run 364 Address data checks, 550 Street data checks and 1,480 assurance checks on each record before being accepted into the database. Data is enriched and transformed by adding the best attributes from source datasets to enhance overall quality of the product. Around 2 million records are updated monthly.

Working through a governance structure, we agree, monitor and support an annual data improvement process with councils which set levels of data quality, completeness and accuracy.

The result is a single, unified source for all addressing and street data used for streetworks, as mandated by the New Roads and Street Works Act 1991 and distributed by Ordnance Survey through the AddressBase range of products.
