A list of central and local government land in England, which may not be registered with HM Land Registry (HMLR).

HMLR has created this dataset for the Ministry for Housing, Communities and Local Government (MHCLG) by combining HMLR freehold polygon data with the public sector ownership data currently openly available from the Office of Government Property.

The dataset is not definitive or complete as not all central and local government data is captured, and/or available, and the two datasets are not held in the same format. The list is therefore indicative rather than definitive.

The dataset includes address data processed against Ordnance Survey’s AddressBase Premium product and incorporates Royal Mail’s PAF® database (Address Data). Royal Mail and Ordnance Survey permit your use of Address Data:

• for personal and/or non-commercial use
• in relation to the analysis of public sector land and property.

If you want to use the Address Data in any other way, you must contact Royal Mail. Email

Address data

The following fields comprise the address data included in the dataset

• Property Name
• Street No
• Road

The official plan produced by Land Registry mapped against the Ordnance Survey map showing the extent of land in an individual registered title including any references to additional detail further described in the register. The Title Plan is a record of the registration at the time of registration and is not maintained or changed over time unless there is a specific change in the extent or references of the registration.

Otherwise known as Land Registry Index polygons, these polygons are shapes that show the position and indicative extent of a registered property.

This dataset is refreshed on a weekly basis from the datasets the team works on daily.Last update date: 05 September 2025.National Highways Operational Highway Boundary (RedLine) maps out the land belonging to the highway for the whole Strategic Road Network (SRN). It comprises two layers; one being the an outline and another showing the registration status / category of land of land that makes up the boundary. Due to the process involved in creating junctions with local highway authority (LHA) roads, land in this dataset may represent LHA highway (owned by National Highways but the responsibility of the LHA to maintain). Surplus land or land held for future projects does not form part of this dataset.The highway boundary is derived from:Ordnance Survey Mastermap Topography,HM Land Registry National Polygon Service (National Highway titles only), andplots researched and digitised during the course of the RedLine Boundary Project.The boundary is split into categories describing the decisions made for particular plots of land. These categories are as follows:Auto-RedLine category is for plots created from an automated process using Ordnance Survey MasterMap Topography as a base. Land is not registered under National Highways' name. For example, but not limited to, unregistered ‘ancient’ highway vested in Highways England, or bridge carrying highways over a rail line.NH Title within RedLine category is for plots created from Land Registry Cadastral parcels whose proprietor is National Highways or a predecessor. Land in this category is within the highway boundary (audited) or meets a certain threshold by the algorithm.NH Title outside RedLine category is for plots created in the same way as above but these areas are thought to be outside the highway boundary. Where the Confidence is Low, land in this category is yet to be audited. Where the Confidence is High, land in this category has been reviewed and audited as outside our operational boundary.National Highways (Technician) Data category is for plots created by National Highways, digitised land parcels relating to highway land that is not registered, not yet registered or un-registerable.Road in Tunnel category, created using tunnel outlines from Ordnance Survey MasterMap Topography data. These represent tunnels on Highways England’s network. Land is not registered under National Highways' name, but land above the tunnel may be in National Highways’ title. Please refer to the definitive land ownership records held at HM Land Registry.The process attribute details how the decision was made for the particular plot of land. These are as follows:Automated category denotes data produced by an automated process. These areas are yet to be audited by the company.Audited category denotes data that has been audited by the company.Technician Data (Awaiting Audit) category denotes data that was created by National Highways but is yet to be audited and confirmed as final.The confidence attribute details how confident you can be in the decision. This attribute is derived from both the decisions made during the building of the underlying automated dataset as well as whether the section has been researched and/or audited by National Highways staff. These are as follows:High category denotes land that has a high probability of being within the RedLine boundary. These areas typically are audited or are features that are close to or on the highway.Moderate category denotes land that is likely to be within the highway boundary but is subject to change once the area has been audited.Low category denotes land that is less likely to be within the highway boundary. These plots typically represent Highways England registered land that the automated process has marked as outside the highway boundary.Please note that this dataset is indicative only. For queries about this dataset please contact the GIS and Research Team.

Integrated Site Assessments are carried out by Natural England staff to assess the condition of notified features on Sites of Special Scientific Interest, and Indicators of Success on Higher Level Stewardship agri-environment schemes. The ISA process integrates surveys for both purposes, so where they co-occur they are usually recorded together. Individual surveys include the recording of a variety of species within SSSI Units and/or Rural Land Register Parcels, as well as other non-biotic measurements such as vegetation structure, which together are used in the assessment of SSSI feature condition, Indicators of Success, or both. Species records are associated with the SSSI units and/or RLR Parcels containing the list of features which are the subject of each part of the ISA survey, so survey 'feature lists' are used to define discrete geographic areas within which the species were recorded. Precise BNG grid references, or eastings and northings, are not recorded for individual species, and the precise extent of the features (usually semi-natual habitats) within the SSSI units and/or RLR parcels is unknown. Each species record is provided with additional attribute information including the list of features assessed, the variable and summary value. Species recorded are mostly vascular plants, often because they are used within ISAs to indicate good or poor habitat condition. Only species that were actually seen are included - there are no 'absence' records. Attribution statement: © Natural England copyright.

This layer identifies all the land owned and managed by the County Council forming the Councils County Farms Estate. Further details about the Estate can be found on the Council’s website as a link under Environment. The layer provides field numbers and the area of each polygon.The layer is linked to a confidential comprehensive property database which records the data essential for the effective management of the Estate including tenants contractual details, term dates, rents, review dates.The areas forming the County farms estate are identified by polygons and the field number and area is provided for each. The field number is an identifier unique to the Estate which has been generated by the Council and is not an Ordnance Survey or Rural Payments Agency identifier.The data is normally updated each year following any tenancy changes in October, but may be updated at other times if land or properties are sold or acquired.The Title to the land within the County Farms Estate has been registered with the Land Registry and the process of checking registered Title as recorded by the Land Registry against Title according to County Farm records is ongoing and errors rectified. The data on the database and the data on the mapping layers are checked at least once a year after any changes in areas in October each year.

Brownfield lands are areas of previously developed land available for residential and mixed-use developments. All local planning authorities are required to publish a Brownfield Land Register to encourage delivery of housing and investment in the area. Brownfield sites that are below 0.25 hectares may not be shown on the map. The GIS files show the indicative boundaries, please contact the relevant London Borough to confirm accuracy. NOTE: The boundaries are based on Ordnance Survey mapping and the data is published under Ordnance Survey's 'presumption to publish'.Contains OS data © Crown copyright and database rights 2019.
