The NSG is the definitive database of streets in England and Wales. It is principally 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).
The Local Street Gazetteer (LSG) also acts as a Local Authority's definitive dataset of the streets in their administrative areas and contains details on the highway, street or footpath, who is responsible for maintain it, what is it made of and a variety of other information that the Local Authority holds as attribute date. E.g. designations and related legal orders.
Certain other organisation may use NSG data under agreement with a statutory body they are working on behalf of to help deliver their core services. For example contractors to a Highways authority may use NSG data, however the data should be supplied by the eligible organisation. Where these parties require access directly from the NSG certain qualifications must be met and a charge for access would be payable.
Yes. All data entry conventions for the LSG and best practice guidelines are contained in the NSG Data Entry Conventions and Best Practice document. Files submitted to the NSG hub should be generated using the Data Transfer Format 8.1.
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. Subsets of the LLPG are supplied to GeoPlace in the form of authority address updates. GeoPlace compiles these within GeoHub, together with a number of other input data sources, to form the basis of the National Address Gazetteer.
There are a number of outputs from GeoHub including data which forms a core part of the AddressBase® range of products, available from Ordnance Survey.
Access to the search facility
The search facility is available to all participating DCA authorities. This service is not available to members of the public.
All new requests for logins to the site must be made via the DCA Principal Contact or Authority Address or Street Custodian.
An email needs to be sent with the following information to the helpdesk:
There is no charge for this service.
Access to NSG Upload
Only two login's per authority/organisation are permitted for uploading data to the NSG. To find out who has this access in your authority contact the helpdesk.
Access to NSG Download
To request additional access to the NSG download facility an email will need to be sent by the Authority Street Custodian with details of the user requiring this access.
If you are not a local highway authority please go to the Register for Street Services section.
Access to My Annual Improvement Schedule
Access to complete the annual improvement schedule is provided to the Authority Street Custodian only. This is usually available for completion around the end of February each year. Communications are sent out with more details when this is available. You will be able to review what was submitted in the previous years questionnaire through this link.
There are three principal pieces of legislation that apply to the Street Naming and Numbering, which are:
GeoPlace are unable to make changes to any addresses held in the National Address Gazetteer. The Local Land and Property Gazetteer (LLPG) Custodian at your local authority is responsible for creating and maintaining streets and addresses, which are then passed on to GeoPlace in the form of change only updates.
If you are having any problems concerning your address please contact your local authority who will be able to check that the data they hold is correct and reflected in the National Address Gazetteer.
This will only impact any companies using AddressBase products, so if this does not resolve the issues it could be that the person/company/service concerned are not using this data and therefore need to be contacted direct.
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. GeoHub strips away all leading zeros and does not pad UPRNs with zeros when supplying data.
PLEASE NOTE - This is not the same UPRN that is requested on Energy Performance Certificate forms. For this reference please contact your energy supplier.
This isn't something that can be provided by GeoPlace. You will need to contact the Local Land and Property Gazetteer (LLPG) Custodian or Street Naming and Numbering Officer at the local authority that your address falls under.
If you require multiple UPRN's please contact the OrdnanceSurvey to find out what licensing options are available for AddressBase products. You can find out more on the Ordnance Survey website - AddressBase products.
The NLPG (National Land and Property Gazetteer) no longer exists as a product, so if you are a new user of Address Data please contact the Ordnance Survey to inquire about or order AddressBase data. You can find out more information about AddressBase products here.
PSMA members who have been receiving address updates prior to 29th January 2014 now receive NLPG re branded (AddressBase Incremental Change Supply (ABICS)). This data will continue to be supplied in the same frequency and format as it is now, until an acceptable alternative is available.
If you receive an ABICS and require a fresh cut of the same data click here to download the re supply order form.
You can request one refresh of data per financial year at no cost. Otherwise it is £155.00 plus VAT for each subsequent Order made in the same financial year.
It is no longer possible to expand your data coverage, change the frequency of supplies, or place a new order for data, you will need to contact the Ordnance Survey PSMA helpdesk to arrange taking AddressBase data instead.

Under the GeoPlace services pages the FTP link can be found under Address - Our Space.
Please read GeoPlace's FTP Site User Guide which tells you how to access, upload and download files from the FTP server.
There is a separate username and password for the Address FTP site and the Street FTP site. The passwords stored by GeoPlace are encrypted, so if you do not have this information, and cannot find this internally then please contact the helpdesk who will be able to reset the password for you, the username will always remain the same.
Please bear in mind resetting the password will affect anyone, or any systems using this login information.
Please note: the FTP site is a data transfer facility therefore files are deleted after 3 months.
There are 3 methods you can use to gain access to the FTP server:
- Internet Browser (please note that not all browsers support the file transfer protocol)
- Dedicated FTP client
On the FTP site each authority has been assigned its own home area. Contained within this area are 2 directories; IN and OUT. In order to send (upload) files to the Address hub you should place them in the IN directory. Any files supplied to you will be placed in the OUT directory (in a sub-folder) for you to download.
On the right hand side of the page is a searching pane.
- Firstly, choose the layer you wish to carry out a search on from the 'select layer' drop down menu.
- Enter your search criteria which could be a UPRN, postcode, USRN, property name, street name etc and click 'Search'.
- The first 20 results will be shown in a table underneath the map window and those 20 results will be displayed on the map.
- To view information about your selection you can click on the BLPU point or street on the map, and an information pane will appear on the left hand side of the screen with details about that record.
- You can zoom to one of the individual results by clicking the 'zoom to' button on the right hand side of the record in the results table, or view information about that record by clicking the 'show details' button in the results table.
- Previous results will remain in the window in the form of tabs, which can be closed by using the x in the corner of the search table.
The size of the map window can be made smaller by clicking on the five dots that appear either at the bottom or the side of the map window and then dragging them to resize the window. This setting will remain for the remainder of your session and will be reset when you log out.
Are Custodians able to manage access for individuals within their organisation to the GeoPlace services?
Access to the search site, COU report viewer and NSG Download/Upload needs to be requested through [email protected] still. There are plans in the future for this to also be managed by the Custodian via the GeoPlace services pages.

After this, your submission is locked. You will be notified via email once the submission has finished. If unsuccessful, please download the error report, correct the errors and repeat the above process. For more information on the error codes please read the compliance check specifications: DTF 8.1
In order to access the data you must first register as an authorised statutory undertaker or user of the data. This can be done online here: NSG Registration
Alternatively data can be provided on DVD/CD which will incur an administrative charge
The Direct Access service was set up as it is increasing evident that much of the work that Local Authorities and Statutory Undertakers undertake was being carried out by other parties under contract. Although technically the NSG data should be obtained from each individual organisation, it was clear that when an company has multiple contracts and is working with multiple organisations, methods of obtaining data are inconsistent, infrequent and in some cases non-existent. The Utility and Contractor community and the HAUC group therefore requested that a process was developed to allow contractors Direct Access to NSG data.
The key requirements of Direct Access are as follows:
1) Must declare the organisation it is downloading data on behalf of.
2) Must only download data where the appropriate Ordnance Survey licences are in place.
3) Will not be allocated a DfT code to issue street works notices or permit applications in their own right.
When a Contractor downloads data, the transaction will be recorded and reported to the appropriate bodies. At this current time these are:
- the Authority whose data was downloaded,
- the Authority or Organisation that the contractor is working on behalf of GeoPlace LLP
NB that the confirmation of licence agreement is subject to audit by Ordnance Survey.
Once agreement is in place the number of users within a single organisation is currently unlimited. Each person will be allocated their own account and is able to download different data as required.
The current annual cost for this Direct Access service is £3200+VAT.
This service is available to any organisation that is using data for street works, Highways maintenance, and traffic management on behalf of either Statutory Undertakers or Highways Authorities. Please note the service offered is for access to NSG data directly. Use of the data is still governed by individual contracts in place with Local Highways Authorities or Statutory Undertakers.
To request this service please send a purchase order, along with details of the Primary contact for the Contractor organisation. On receiving the purchase order we will set up access immediately.
Once you are logged in to the GeoPlace services page, if you have NSG downloader access you will be able to access Download Data from the Street menu.
The download matrix is displayed for all local and regional (TfL, Highways England, Network Rail and Welsh Government) highway authorities with the options to download Level 3, ASD, OD Files and in some cases where appropriate Lane Rental information (Kent and TfL).
To download you will need to select the relevant file from the authorities listed of which the currency of the data is shown. There are also national compilations available for organisations that require a full national dataset. Please note that for contractor access you will only be able to access data for organisations that you work on behalf of.
If you wish to customise this view to display the organisations you download data for, then use the Manage Your Downloads button on the right hand side of the page and select the organisations you wish to download data for. These will then become the only organisations available on the download matrix.
If at any time you need to reduce or expand the list this can also be done through the Manage Your Downloads button.
During May 2013 OD File Exchange was introduced, this means to download NSG data a user must have a current OD file held on the NSG website. The OD file must have been made in the previous or current month of the requested download.
This will apply to all Utilities and Local Authorities. This has been implemented following a request from the Highway Authority and Utility Committee (HAUC) to ensure that all OD files are kept up to date and stored centrally on the NSG website. For more information on how to upload a file please see the ‘How do I upload NSG/ASD data?'
Details of all compliance tests conducted by the hub are contained in the DTF8.1 Compliance Check Specification document which is available under the login for DCA (Data Cooperation Agreement) Authorities on the services site.
DTF 8.1 Files submitted to the NSG hub are health checked using DTF 8.1 Health Check Specification. This is to assist Custodians in improving the quality of their gazetteers.
NSG data is published on the second working day of each month. The published data will contain data submitted by Local Authorities during the previous month.
Statutory Undertakers and Local Authority street works teams should upload the published data on the second working day to ensure consistency between the two datasets.

"whole or part of a highway, road, lane, footpath, square, court, alley or passage"
There are also a number of other statutory definitions of a street which should be referred to in the context of street works and Street Naming and Numbering legislation. The Utilities use the PUSWA Act 1950 definition:
"A street includes any length of highway (other than a waterway) road, lane, footway, alley or passage, any square or court and any length of land laid out as a way whether it is for the time being formed as a way or not, irrespective of whether the highway, road or other thing is a thoroughfare or not."
The New Roads and Street Works Act 1991 defines it as follows:
For England and Wales:
A "street" means the whole or any part of any of the following, irrespective of whether it is a thoroughfare-:
(a) any highway, road, lane, footway, alley or passage.
(b) any square or court and
(c) any land laid out as a way whether it is for the time being formed as a way or not. Where a street passes over a bridge or through a tunnel, references to the street include the bridge or tunnel
A "road" means any way (other than a substitute road made under section 74 (1) of the Roads (Scotland) Act 1984 or a waterway) whether or not there is over it a public right of passage and whether or not it is for the time being formed as a way and the expression includes a square or court and any part of a road.
The Joint Authorities Group (UK) – (JAG (UK)) - represents the organisations responsible for the roads and streets of the United Kingdom. JAG (UK) focuses on the daily operation, the coordination of works for asset or utility network management and other events taking place on the highway. JAG (UK's) member organisations are primarily local authorities and similar bodies whose principal activities are governed by highways, street, road and traffic management legislation.
Their responsibilities include regulation of streets and roads for any purpose, with a view to maintaining public safety, asset integrity and the movement of people and goods. JAG (UK) Support of the local authority streetworks community parallels the work the NSG does with the street data side. Both JAG (UK) and GeoPlace are keen to ensure LHAs work together in the most efficient way possible.
The Highway Authorities and Utilities Committee (UK) (HAUC) (UK)) was established in 1986 by the constituent bodies of the local highway authorities and the utilities to assist the Secretary of State in arriving at proposals for new street works legislation. HAUC (UK) played a significant role in the drawing up of the New Roads and Street Works Act 1991 (NRSWA), its subsidiary legislation and associated Codes of Practice.
The main aims of HAUC (UK) are:
- To advise the Secretary of State on issues relating to street works legislation
- To provide guidance to practitioners
- To provide a forum for matters of mutual interest in relation to street work
- HAUC (UK) is principally made up of member from JAG (UK) (Joint Authorities Group) and NJUG (National Joint Utilities Group)
The SWA Code or formally known as the Department for Transport (DfT) code, is a 4 digit code that has a 2 character prefix e.g. AB1234.
GeoPlace alongside Highway Authorities and Utilities Committee (UK), (HAUC (UK)) manage the allocation of these codes on behalf of the DfT. The code uniquely identify Street Work Authorities and Statutory undertakers that have a legal right to carry out works in the highway. In order to download National Street Gazetteer (NSG) and/or Associated Street Data (ASD) data from our website you need to have a SWA code assigned to your organisation. These codes are also a key requirement of the EToN noticing process.
Apply for a SWA code Register for an NSG user account or request a SWA code on the NSG Registration.
The Trunk Road Street Gazetteer (TRSG) is the gazetteer that is used by the Highways Agency on all major motorways and trunk roads in the UK. Although built to the same specification and DTF, it is distinctly separate from the NSG. And instead of USRNs is uses a different reference, the TRRN (Trunk Road Referencing Number).
For completeness the NSG still contains the complete network of trunk roads and motorways in the LSG with USRNs, however for noticing purposes Statutory undertakers must use the TRSG where it is available. It is recommend that NSG and TRSG are used in partnership to ensure that all parties understand where their interests start and finish.
Anyone who has interest in a motorway or trunk road and who would like to receive copy notices of any works via EToN, should contact the TRSG Custodian. Details can be obtained via the helpdesk
The system of roads classification is intended to direct motorists towards the most suitable routes for reaching their destination. It does this by identifying roads that are best suited for traffic.
All UK roads (excluding motorways) fall into the following four categories:
- A roads – major roads intended to provide large-scale transport links within or between areas.
- B roads – roads intended to connect different areas, and to feed traffic between A roads and smaller roads on the network.
- Classified unnumbered - smaller roads intended to connect together unclassified roads with A and B roads, and often linking a housing estate or a village to the rest of the network. Similar to ‘minor roads' on an Ordnance Survey map and sometimes known unofficially as C roads.
- Unclassified – local roads intended for local traffic. The vast majority (60%) of roads in the UK fall within this category.
Road classification uses a common system of route numbering, which is centrally administered for England and Wales by the Department for Transport.
The primary route network (PRN) designates roads between places of traffic importance across the UK, with the aim of providing easily identifiable routes to access the whole of the country. Primary routes are marked green on most road maps, as opposed to the more common red of an ordinary A road; and road signs are green with white and yellow text.
From April 2012 Local Authorities are responsible for designating road classifications and the primary route network. GeoPlace are responsible for consolidation of data on behalf of DfT alongside ensuring their inclusion in the NSG
There are four statutory Special Designations that if exist should be created, maintained and submitted to the NSG:
- Protected Street.
- Traffic Sensitive Street.
- Special Engineering Difficulty.
- Lane Rental.
The information on how to collect this data is found in NRSWA under ‘Streets subject to special controls' and is usually subject to criteria and consultation.
There are a further optional special designations which can be found in the Data Entry conventions and our guidance is to collect as many you can to provide tighter controls over your network.
There are both advised and mandatory changes required to an authority's LSG in preparation for a Permit Scheme.
Fundamentally you need to ensure the quality and accuracy of your Additional Street Data (ASD) information.
You need to ensure that Interest records correctly reflect what is publicly maintainable within your authority. An authority cannot receive permits on private streets.
Category 0, 1 and 2 streets should be reviewed as they feed into strategically significant streets and the section 74 overrun process
Special Designation Records
Special designations provide tighter control over your highways. Protected Streets, Traffic Sensitivity and Special Engineering Difficulty also feed into the charge rates and should be reviewed as a matter of priority.
In preparing for a Permit Scheme it is essential initially to ensure that your private streets are have a separate district within your OD file. Upon going live the district function of the district used for publicly maintainable streets should be set to 9 to dictate that the USRNs are now subject to permits.
You can find more detail in the permit scheme preparation document released by GeoPlace.

Why am I unable to specify which email addresses my data linking, priority objects and coordinates notifications go to via my user profile?
Only the reports sent directly from our database are able to accommodate more than one email address at this stage. This means this can only be updated for COU submission notifications, health check notifications and comparison report notifications.
Coordinates and data linking are not included in this as these are sent via a different mechanism, but is something that will be looked into for the future.
With an Effective Date of 1st April 2012, it replaces similar arrangements between all councils and the Local Government Information House (LGIH - a subsidiary of the LGA) which have been in place since 2005 (the Mapping Services Agreement (MSA)) expired on the 31st March 2012.

Through agreement with Scotland's Improvement Service Company, working on behalf of Scottish Government, the National Address Gazetteer includes Scottish address data.
The National Address Gazetteer is the single source from which the AddressBase® products are developed.
Authority updates are supplied from the LLPG by address contributing authorities to GeoPlace on a regular basis. GeoPlace combined this local intelligence with other national data sources to produce the National Address Gazetteer infrastructure which in turn form the AddressBase range of products, made available through Ordnance Survey.
Ordnance Survey AddressBase® FAQs also contain further information.
Once the records are received from local authorities, GeoPlace undertakes a large data validation exercise testing the incoming LLPG and LSG data against the Data Transfer Format (DTF) and the Data Entry Conventions (DEC) specifications. Both NLPG and NSG are then compared against each other to highlight any street record anomalies.
A series of 500 health checks are also carried out on the two datasets. Further checks are carried out on logical data consistency, classification and address mismatches between the NLPG, Ordnance Survey, Valuation Office Agency and Royal Mail's Postcode Address File (PAF) to form the National Address Gazetteer Database based upon the use of the UPRN and USRN.
By taking data from multiple sources; local authorities, Ordnance Survey, Royal Mail and the Valuation Office Agency and validating it against each other, GeoPlace can be confident that change intelligence on the ground is captured.
In addition to the work carried out ensuring data conformance, GeoPlace works to ensure the product is fit for purpose and meets user requirements from both the public and private sector.
GeoPlace has achieved certification to two industry recognised and highly respected international standards, namely ISO9001 for Quality Management, and ISO/IEC27001 for Information Security. Certification to these standards is part of GeoPlace's drive for quality, accuracy, and security for all the work we do.
The PSMA Helpdesk can be contacted with any questions.
For Government organisations the UPRN is an underpinning linking mechanism that removes error in data exchange and communication, supports citizen service improvement and delivers efficiency gains in operational processes.
For commercial organisations AddressBase provides the link between postal addresses and the UPRN as a means to locate and uniquely reference customers and assets to enable business growth, gain competitive advantage and reduce operational costs.

Please note: the passing of any licensed addressing data to a contractor will require the relevant Royal Mail terms being passed on to them. In addition, their use of that data (including the number of users) must also form part of the required annual declaration(s) made for such use. The terms that you need to pass on are available here on the Ordnance Survey website.
1. Passing NLPG data for use by a Contractor: As NLPG usage is licenced to your authority via the PSMA, you will need to agree a PSMA Contractor Licence with your Contractor (advice should be sought from Ordnance Survey if you have any questions). The PSMA Contractor Licence can be found on the Ordnance Survey website.
2. Passing LLPG data for use by a Contractor: The licence for use of any Ordnance Survey/Royal Mail intellectual property contained in your LLPG is provided to your authority through the PSMA as an NLPG Addressing Dataset. Therefore, any onward use by a Contractor of your LLPG, as PSMA NLPG licenced data, will require a PSMA Contractor Licence to be agreed. The PSMA Contractor Licence can be found on the Ordnance Survey website.
3. Outsourcing or sub-contracting the creation, maintenance and provision of Authority Updates to GeoPlace from a Participating Authority:
In the Data Co-operation Agreement (DCA) the licence covering the use of the Supplied Data (defined in the DCA as the: GeoPlace Databases, Ordnance Survey Data, Royal Mail Data and VOA Data) for the creation, maintenance and provision of Authority Updates to GeoPlace is detailed in the main agreement as part of the DCA documentation. This licence is limited to these processes and does not cover any usage of LLPGs and/or LSGs and/or the NLPG and/or the NSG either internally within your Authority or within any sub-contracting arrangement established by your Authority for the use of this data, (see 2) above).
Therefore, in order to licence the Supplied Data as part of the provision of Authority Updates to GeoPlace, to an outsourced LLPG and/or LSG maintenance contractor, you will need to agree the terms (see DCA clauses 2.2, 6.1.4, 21.3 and 21.4) no less onerous than those set out in: a) the Contractor/Agent Licence contained in Schedule 4 of the DCA; and also b) the Royal Mail terms as Appendix 1 to Schedule 4 contained in Schedule 7 of the DCA documentation.
Please note: that if your Authority does enter into a sub-contracting or outsourcing arrangement in order for Authority Updates to be sent to GeoPlace, the name and contact details of the sub-contractor must be sent by email to GeoPlace, to: [email protected] within thirty (30) Working Days of their appointment in accordance with clause 21.4 of the DCA.
4. Passing NSG data for use by a Contractor: Use of NSG data is underpinned by the licence for Ordnance Survey material and intellectual property provided under the PSMA. You will need to agree a PSMA Contractor Licence with your contractor to enable their use of the NSG. The PSMA Contractor Licence can be found on the Ordnance Survey website.
5. Passing LSG data for use by a contractor: Use of LSG data is underpinned by the licence for Ordnance Survey material and intellectual property provided under the PSMA. You will need to agree a PSMA Contractor Licence with your contractor to enable their use of your LSG. The PSMA Contractor Licence can be found on the Ordnance Survey website.
6. Outsourcing or sub-contracting the creation, maintenance and provision of Authority Updates to GeoPlace from a Participating Authority:
In the Data Co-operation Agreement (DCA) the licence covering the use of the Supplied Data (defined in the DCA as the: GeoPlace Databases, Ordnance Survey Data, Royal Mail Data and VOA Data) for the creation, maintenance and provision of Authority Updates to GeoPlace is detailed in the main agreement as part of the DCA documentation. This licence is limited to these processes and does not cover any usage of LLPGs and/or LSGs and/or the NLPG and/or the NSG either internally within your Authority or within any sub-contracting arrangement established by your Authority for the use of this data, (see 5) above). Therefore, in order to licence the Supplied Data as part of the provision of Authority Updates to GeoPlace, to an outsourced LLPG and/or LSG maintenance contractor, you will need to agree the terms (see DCA clauses 2.2, 6.1.4, 21.3 and 21.4) no less onerous than those set out in: a) the Contractor/Agent Licence contained in Schedule 4 of the DCA; and also b) the Royal Mail terms as Appendix 1 to Schedule 4 contained in Schedule 7 of the DCA documentation.
Please note: that if your Authority does enter into a sub-contracting or outsourcing arrangement in order for Authority Updates to be sent to GeoPlace, the name and contact details of the sub-contractor must be sent by email to GeoPlace, to: [email protected]within thirty (30) Working Days of their appointment in accordance with clause 21.4 of the DCA
ESUs should only be split where there is a junction between two or more streets. Where the physical nature of the street does not change, and there is no legal restriction over use of the highway, then all additional information should be dealt with using part street records where possible.
If the physical nature of the street changes, for example, it moves from a carriageway to a pedestrian way, then a split in the ESU can occur.
If there is a specific legal restriction in who can use the street, for example, the highway dedication changes from a Bridleway to a Street Open to all Vehicles, then a split in the ESU can occur.
An obstruction should be reported when something that physically obstructs a street user from traveling along it from one end to the other. Some examples are; bollards (raising or fixed), gates, plant pots, raised bridge etc. Obstructions can occur on any ESU or at the junction with another ESU (where it would need to be added to both ESUs).
ESUs should only be split at an obstruction where without the obstruction it would still be considered a junction. For example, if that obstruction wasn't there, would the ESU be considered to be continuous?
If travel is not possible from one side of the obstruction to the other by any means, for example, if a there is a continuous brick wall between the two ESUs then this should be considered as separate streets.

Capturing the street geometry
Each authority will capture the street using a USRN from their allocated range. As per the Data Entry Conventions both authorities will need to submit the same ESUID for that street. This ensures there is no conflicting geometry when data is compiled nationally. Both authorities must agree which ESUIDs will be used.
Both authorities must submit ASD (type 61 and 62) on the street. The type 61 Interest record is the key to identifying the primary contact for any works on the street.
