How do I order NLPG data?

If you wish to order NLPG data, please use PSMA Ordering.

If you have previous NLPG data supply and wish to change the frequency of updates or require a fresh cut of the same area please click here.

How can I use my internal commercial premises data to validate the content of my LLPG?

Most councils will maintain a list of business occupiers within their environmental health and licensing departments. For some councils this information has already been matched to their LLPG either as part of a snapshot data match or as part of a regularly maintained link.

Extracting this business name data with the associated address and unique id can be useful in assisting the verification exercise of the unsynchronised AL2 commercial address records. GeoPlace have helped a number of councils using this data and removed the burden of manually reviewing the data internally.

If you require more information on how this can be achieved please contact the Data Management Data Match or Gazetteers Support at GeoPlace.

What is the Local Land and Property Gazetteer (LLPG)?

It is a BS7666 compliant address database maintained and used by a relevant local authority. As the database is maintained centrally and to a common standard it delivers real efficiencies and improvements in service delivery and interoperability when implemented throughout all parts of an organization. Each LLPG is compiled into the National Land and Property Gazetteer (NLPG).

What is the National Street Gazetteer (NSG)?

It is the definitive list of streets in England and Wales and is used by Local Authorities streetworks departments to coordinate the work that is being performed on the highway within their administrative area. It aims to minimise disruption and ensure public safety and forms part of the statutory duty of the local authority as defined in the New Roads and Streetworks Act (1991) .

Who is Local Government Improvement and Development?

It is a wholly owned subsidiary of the Local Government Association, created by and for local government in England and Wales. They are accountable to local government through a board of directors half of whom are local government councillors. They work in partnership with all councils to enhance the performance of the best, accelerate the speed of improvement of the rest and develop the sector as a whole.

What is a UPRN?

A Unique Property Reference Number (UPRN) is an attribute of a Basic Land and Property Unit (BLPU). It is a unique reference number that links together information and is used to cross-reference associated data to.

UPRNs are integers (numbers) that can be up to 12 digits in length; they can therefore be less than 12 digits long and do not require leading zeros. However some gazetteer database applications will pad UPRNs that are less than 12 digits with zeros. The NLPG Hub strips away all leading zeros and does not pad UPRNs with zeros when supplying data.
