Linkages permitted for each LPS#
Last modified: 19 Oct 2026
The table below summarises the linkages that are permitted for each LPS. Please note that not all of these linkages are available yet because LPS, linked data owners and UK LLC need time to complete the necessary governance and data pipelines to enable data to flow into the UK LLC Trusted Research Environment (TRE). The Available linkages guide provides researchers with a list of the LPS that are already linked to their participants’ NHS England health records and geographic datasets and can therefore be included in an application to UK LLC.
See the NHS England dataset restrictions guide for a full list of research restrictions.
