Highlights of the OS NGD data enhancements released to customers in Autumn 2025
Address
The OS GB Address Collection and OS Islands Collection now contain a new Royal Mail Address Feature Type, representing a major step forward in address data provision. These feature types combine the full Royal Mail Postcode Address File (PAF) content with Ordnance Survey’s authoritative geospatial attribution for the first time.
Highlights of the new Royal Mail Address Feature Types:
Full PAF content: 100% coverage of Royal Mail’s delivery point addresses, with UDPRN (Unique Delivery Point Reference Number) as the primary key.
Multiple UDPRN to UPRN matches: Identifying where multiple addresses in PAF can be associated to a single UPRN (Unique Property Reference Number).
Enhanced attribution: Additional OS-derived metadata, including geometry, positional accuracy, geometry allocation method, relationships with local authority addresses and standard OS NGD attribution.
Examples of Built Address and Royal Mail Address features and the attribution provided for these features.
Buildings
Enhanced Physical State attribution is now available for Building features. The Physical State attribute classifies buildings as 'Built', 'Under Construction', or 'Derelict' to provide a clear, up-to-date view of their structural condition. Customers can use this attribute to track building construction progress and identify derelict properties; the attribute is also useful to Emergency Services and the planning and insurance sectors as it gives them accurate building lifecycle data.

Land
Intertidal areas obscured by elevated structures, such as piers and jetties, have been added to the Land Feature Type for more complete coverage of the intertidal zone.

Land use
Enhanced Status attribution is now available for Site, Building Part, Land, Rail, Road Track Or Path, Structure and Water features. The Status attribute reflects the state of a feature in relation to either its physical condition or the activity the feature is intended to support. This value is either inherent from the nature of the topographic feature or can be inherited from the Site the feature lies within.
Please note that Status attribute values are only recorded against a subset of over 100 Site types, including Railway Stations, Schools, Sports Grounds, Power Stations and Quarries; the full list of Site types is available in a table on the OS Land Use Features Collection page.
National Land Use Database (NLUD) values are now populated for 'Derelict Land'.

Transport
New Cycle Lane Feature Type added to the OS Transport Network Collection to identify the location of cycle lanes, either segregated by a physical feature or identified by painted or other signage. The new data will support local authorities, regional transport bodies and central government to undertake planning, asset management and road safety analysis, plus understand connectivity and gap analysis for active travel networks.

New attribution supplied against the Path Link Feature Type to indicate the presence of cycle lanes.
New Bus Lane Feature Type added to the OS Transport Network Collection to identify the location of bus lanes that are segregated by a physical feature or painted section of road only for buses or shared usage. The new data will support local authorities, regional transport bodies and central government to plan street works and conduct connectivity and gap analysis for public transport networks.

Water
Continuous tidelines are now available in the OS Water Features Collection through the addition of two new feature types: Tidal Boundary Continuous High and Tidal Boundary Continuous Low. The latest update delivers automated, continuous mean high water and mean low water tidelines by dissolving existing Tidal Boundary features into seamless lines that are topologically coincident with their source water features. The two new feature types will help customers to conduct environmental management and accurately model coastal change and flooding.

New attribution is supplied against Water Link features describing the average width of the watercourse and the width derivation method. Minimum and maximum widths of watercourses are also supplied where a Water Link feature has been captured as a topographic polygon. The new watercourse width attribution will support ecological and flood modelling, infrastructure planning and situational awareness for emergency services.
Examples of the new watercourse width attribution now available for Water Link features. A background map has been included for context.
June 2025 – OS NGD access enhancements in OS Select+Build
Highlights of the OS NGD data enhancements released to customers in March 2025.
Highlights of the OS NGD data enhancements released to customers in March 2025:
Buildings
New Building Access Location Feature Type added to the OS Building Features Collection. Building Access Location features identify access points to key public buildings for vehicles and pedestrians, enhancing urban planning, emergency response, and accessibility.
Roof Shape: Identifies the predominant geometric shape of a building's roof, aiding in visualisation and architectural analysis.
Roof Aspect: Provides information on the orientation of a roof, which is useful for solar energy planning and environmental studies.
Green Roof Presence: Indicates whether a building has a green roof, supporting sustainability and urban greening initiatives.
Solar Panel Presence: Shows if solar panels are installed on a building's roof, helping in renewable energy assessments and planning.
Roof Material: Details the type of predominant material used for a roof, which is important for construction, maintenance, and environmental impact studies.
Building Height: A comprehensive set of five attributes detailing the heights of various parts of a building, including both absolute and relative measurements. This enhancement supports urban planning and Emergency Services.
These buildings enhancements aim to improve visualisation, urban development planning, emergency response, and sustainability initiatives. More information on the March 2025 buildings enhancements is available from the OS NGD Buildings pages in the 'Using OS NGD Data' section.
Examples of building features and attributes provided by the OS NGD Buildings and OS NGD Land Use Themes.

Geographical Names
New Crowd Sourced Name Point Feature Type added to the OS Named Features Collection, which includes names submitted by expert third parties via the Vernacular Names Tool in the OS Data Hub. Where possible, the crowd sourced names are linked to other OS NGD features, allowing the use of both official and colloquial names together.
Example of a Crowd Sourced Name Point feature being matched to existing OS NGD (Building Part and Address) features via its OSID (OS Identifier) and UPRN (Unique Property Reference Number). A background map has been included to provide context.
Land Use
Three new types of site added to Land Use Sites descriptions: Beach, Military Training Area, and Wind Farm. Over 2 600 new sites have been added to the dataset for this enhancement (1 927 beaches, 90 Military Training Areas and 604 Wind Farms). These are sites that may not be spatially coincident with existing topographic areas (i.e. they may not align with topographic features like field boundaries), unlike other types of site. Beaches will include Site Access Locations with attribution that highlights the nearest public Road Node and the direct distance to that node from the access point on the edge of the beach feature. Military Training Areas and Wind Farms will not include Site Access Locations.
Example of a Land Use Site featuring a description of 'Beach' with Pedestrian and Vehicular Access Locations shown. Background maps are included for context.
An Access Purpose attribute has been added to Site Access Location features for key public sites to identify what the Site Access Location is being used for (Primary Public, Public, Private, or Emergency). The new data will enhance and support situational awareness for emergency responses, hazard planning, and policing operations at key public sites; the data will also support travel modelling and make it easier to assess accessibility to services for the public.
Example of the four types of Access Purpose points within a football stadium for purposes of emergency response and evacuations. A background map has been included to provide context.
Structures
The addition of nine different types of tunnel to the Compound Structure Feature Type. These were added to v2 of the schema on 28 March 2025 and v1 on 09 April 2025.
Transport
New Street Light Feature Type added to the OS Transport Features Collection to identify the location of pole-mounted street lights and provide a reference to the nearest Road Link or Path Link. This is the first consistent GB-wide dataset of street lights that is updated monthly and maintained to defined quality levels.
New attribution supplied against the Road Link and Path Link Feature Types to indicate how well-lit they are. The new data will support the identification of safe routes for active travel use cases .

2024 OS NGD enhancements
September 2024 – OS NGD data enhancements
Buildings
New number of floors attribution added to Building features to identify the maximum number of occupiable floors at or above ground level within a residential or office building. Over 23.5 million office or residential buildings in Great Britain now have a number of floors value, and a total of nearly 47 million floors have been added to the OS NGD. Among other uses, the new attribution will provide emergency services with more information when responding to real-time incidents, such as a fire in a high-rise building, and will help support insurers to improve their risk profiling and underwriting.
Land Use – Enhanced land use attribution, increased coverage for Sites, and more Site Access Location points
New land use attribution will be provided for the OS NGD ‘Features’ Collections for Buildings, Land, Land Use, Structures, Transport and Water. The new attribution maps the OS land use classifications to the National Land Use Database (NLUD) schema and the land use information derived from OS Addressing. The new attribution helps to give more detail about what is contained within a Site – for example, the total number of addresses contained within a single Site and what number of those addresses are defined as commercial, residential, or other.
Greater coverage for land use Sites, particularly non-residential sites, with over 1.5 million Sites added to the OS NGD gradually over the last two years. This has brought the total number of Sites contained within the OS NGD to 26 million.
An additional 180 000 Site Access Location points have been added to the OS NGD. These features show where vehicles and / or pedestrians can access Sites and, among other uses, help the emergency services to identify the most efficient routes for reaching an incident.
Structures
Additional bridge interaction attribution added to Compound Structure features to identify the type of network (road, path, railway, canal, water or multiple) passing over and / or under bridges. Over 660 000 bridge interactions have been added to the OS NGD.
Building Age: The age of the main building in a site, created using Verisk data and OS data.
Construction Material: The primary construction material of the building, created using Verisk data and OS data.
Basement Presence: An indicator to show whether a basement or a self-contained basement flat are present at the building, created using Verisk data and OS data.
Building Description: A new description attribute to describe the nature of the building, derived from its use and relation to surrounding buildings, created using OS data.
More information on the buildings enhancements is available from the OS NGD Buildings pages in the 'Using OS NGD Data' section.

Attribution provided on a building's use, how it is connected to other buildings, additional details on addresses contained within a building, and whether a building is considered to be the main one within a site.
Cross references added between the new Building Feature Type and the Building Part, Site, and Built Address Feature Types.
Transport
New rail feature types added to the OS NGD Transport Network Collection, giving information about the topologically connected rail network:
Available rail network attribution now includes track representation (single / multitrack, siding) and use (freight / passenger / mixed).
New Pavement Link Feature Type added to the OS NGD Transport Network Collection, giving information on the presence of pavements on the Road Network. More information on this enhancement is available from the OS NGD Transport pages in the Using OS NGD Data section.
New attribution added to the Road Link Feature Type, giving details about pavement presence: left or right side of road, coverage, and minimum and average width. More information on this enhancement is available from the OS NGD Transport pages in the 'Using OS NGD Data' section.
August 2023 – OS NGD data enhancements
Transport
Path network coverage extended to all of Great Britain (it was previously just available for urban areas). The road and path networks have been topologically structured together, which has increased the number of features present in the Paths feature types (i.e. Path, Path Link, Path Node, Connecting Link, and Connecting Node Feature Types).
Option to select which data schema version you want to access for certain address feature types (see the Addressing 'Versioning information' page and the 'Data schema versioning' page for more information).
New ability to share your created recipes with other organisations so that they can use exactly the same selections as you (see the 'Downloading with OS Select+Build' page for more details).
