Address data

Local authorities deliver over 700 different services. It is estimated that 85% of authority services have a location element.  Having an unambiguous location reference point shared throughout the local authority saves time and money. 

Location information links services to people through place. This is key to delivering joined-up services.  Whether it relates to providing services to vulnerable people; managing school admissions; planning street works; or mobilising a fire crew to a block of flats.  There is no room for error – completeness, accuracy and timeliness of information is of the essence. 

Local planning authorities (districts; unitaries; metropolitan districts; London boroughs) have a statutory duty to name and number streets and properties.  Following an initiative led by the Local Government Association, over the past 14 years, local authorities have worked collaboratively to develop single address and street data sources demonstrating one of the most successful shared services across England and Wales.

Local authorities gain benefit through efficiencies; savings; and a platform for transformation through this joint work.  The central collation of data by us adds value through standardisation and quality assurance.  The wider public sector benefits as a result and this opens the door for service transformation and efficiency between councils and other bodies they work with.


Addresses play a vital role in communities, allowing us to locate one another and enable a whole range of services to be delivered from the cradle to the grave. 

Most transactions, provided by thousands of different organisations, include an address – from registering to vote, collection of waste, delivery of social care, payment of taxes, connection of utility services, quotation for insurance, delivery of packages, allocation of school places and most crucially responding to emergency situations where time really can be a matter of life or death.

Many of these transactions are underpinned by the address information produced by local authorities and contained within the National Address Gazetteer infrastucture

The National Address Gazetteer infrastructure is the single source from which the AddressBase products are developed and made available free at the point of use by Ordnance Survey for the entire public sector including organisations working on behalf of the public sector, under the Public Sector Geospatial Agreement (PSGA) and One Scotland Mapping Agreement (OSMA).

Being able to access a definitive address list from one central place allows organisations to readily exchange information with each other, streamline services, reduce duplication and facilitate partnership working.



Decommission of OS Address Infrastructure

Since the formation of GeoPlace in 2010, we have been continually working to evolve and improve. We are proud of the work we do and the way that we do it and last week we gained further accreditation of this.   
Up until recently, Ordnance Survey actively captured and maintained its own address data content store – used to create products such as ADDRESS-POINT and Code-Point.  Last week, Ordnance Survey confirmed to us that they have ceased the wholesale capture and maintenance processes they previously carried out, with the primary content now fulfilled from NAG Hub. 
Ordnance Survey continue to work collaboratively with GeoPlace and Local Authorities to ensure the ongoing accuracy of the NAG Hub, however this is now on a more targeted basis. This is a significant step for all of us, local authorities included.
