UK LLC’s unique attributes#
Last modified: 24 Jun 2026
Linkages are dynamic: linkages to NHS England datasets are refreshed every 12 months, and we can provide researchers with access to new or updated LPS datasets as they become available, ensuring the temporal alignment of LPS and linked data
The nature of linkages is consistent: all linkages, data extracts and post-processing are done in the same way, at the same time, across all LPS. This facilitates cross-study analysis as data are directly comparable
The breadth of data types: UK LLC already contains data collected by LPS from across the four UK nations, data from NHS England and place-based data. In 2026, data from NHS Wales, NHS Scotland, the Department for Work and Pensions (DWP), and HM Revenue and Customs (HMRC) will be uploaded into the TRE
The range of linked health records: UK LLC has the maximum number of variables permitted by NHS England, across a wide set of linked health records, covering primary, secondary and community-based care
A dynamic library of research products: reusable syntax and derived variables are developed by UK LLC researchers and made available to all TRE users
Harmonised variables: sex, gender, ethnicity, year of birth and education have been harmonised across all partner LPS, so researchers can quickly understand the socio-demographic makeup of their study population
The simplicity of the application process: researchers complete just one form to apply for data. Researchers already working in the UK LLC TRE add additional datasets as they become available, via UK LLC’s amendment process.
