Government Property tools – InSite

InSite Service

The InSite Government Property Portal is now available. It is the central database of Central Government Civil Estate properties and land. It is also used to record the estates of the Devolved Administrations and increasingly by other wider public sector bodies. Download the accompanying user manual.

Inputting new information

Local Authority users should note that existing local authority data from the e-PIMS system has not been migrated into the new system and as a result your property data will therefore not be visible in the new system. The e-PIMS / InSite team will retain a copy of the data from a fixed point of 31st March 2025. If you would like to request a copy you can do this by emailing the InSite™ team at [email protected]

Local Authorities can input new information anytime from the 1 April 2025. You will have full access to do this, including the ability to advertise surplus properties. 

You may wish to wait until the further release is live, which will enable a bulk upload tool for Local Authority users. This should enable you to upload the up-to-date data from your own asset management system, which will significantly reduce the time required to update and/or clean the existing data sets.  Your new data will of course need to be in the right format and more details are available from the InSite team. 

Access to other data

You can still access property data related to central government and its agencies through the InSite™ system, including access to surplus properties. As with e-PIMS, this will exclude sensitive or commercial information. Likewise, once uploaded to InSite any information Councils mark as sensitive will not be visible to others. 

Transparency Data: 

Local Authority Transparency Data will no longer be updated on data.gov.uk. 

The snapshot of Local Authority data taken on 31st March 2025 will remain visible until 1st June 2025, after which you will need to ensure you have uploaded your current data, or have alternative means of publishing your data to comply with data transparency regulations (which you probably already do, as part of your current asset management data systems). 

One Public Estate partnership requirement 

Although not mandatory for all local authorities, those joining the One Public Estate programme consent to share, and update council property asset data with central government annually, now through the InSite™ platform, subject to the availability of a bulk upload to the system. 

Following initial (bulk) upload, the annual updating requirement will apply to all OPE partnership councils (and will be subject to audit sampling).

InSite™ features

InSite™ records the precise location of property, along with information such as landlord details, lease data and usage. Users are able to find properties on an electronic map, amend their own property details, and use the system to search for vacant space.

The benefits of using InSite include, but are not limited to:

• access to data on central government land and buildings creating collaboration between central and wider public sector
• advance information of surplus land before it is disposed of outside of government
• detailed property searching and mapping, including land registry titles of all land packages and vacant land and property
• free access for all users - local authorities will not have to establish their own systems at their own cost
• standardised and consistent data capture, which allows for better estate planning and management between public sector bodies
• benchmarking capability
• further improvements and technical additions to the InSite service to support and provide a wider functionality for local authorities
• support from Cabinet Office.
