Special Licence

Special Licence (SL) data collections are anonymised but contain more detailed information than End User Licence (EUL) data.

All requests for SL datasets require completion of a set of forms to provide further details regarding your intended use of the data. You will be directed to the relevant forms during the ordering process. The completed forms are sent to the data depositor for approval, and permission has to be received before access to the data can be granted.

Some SL data collections are only available to UK applicants and users are advised to check the access information in the relevant Discover record for details. 

Users who obtain access to SL data are required to read and follow the advice in the document Microdata Handling and Security: Guide to Good Practice, which includes guidance on avoiding inadvertent statistical disclosure, storing and accessing data securely, and how to permanently destroy copies of data files.

If you require access to ONS SL data you must be accredited by the UK Statistics Authority as an Approved Researcher, in accordance with the Statistics and Registration Service Act 2007.

Access to ONS SL data is only available to UK applicants for non-commercial purposes.

Information on how to download/order special licence data is available from Download and order.
