Data access

Researchers in the UK and around the world can access data from our cohort studies free of charge. We have described the CLS data access strategy in our CLS Data Access Framework.

Access to research data varies depending on how we have de-identified and classified the data (CLS Data Classification Policy).

Most CLS research data are publicly available through public repositories, primarily the UK Data Service. There are a few specialised data available in other public data repositories.

Data not publicly available via these public routes, and proposals for novel data linkages and data enhancements, can be requested directly from CLS.
