These pages are in public beta. You can complete this short questionnaire to provide feedback.

These pages provide a link to the description of data sets readily available to request through our Data Access Request service (DARS). These data may be provided in the Trusted Research Environment (TRE) or as an extract. For clinical trials you may also want to use the DigiTrials Service which can also provide access to this data.

We do not make all our data sets available for public release.
Some data sets are only available to those organisations which commission and pay for health and care services.
Other data sets may only be available to a listed number of approved users. To enquire about any other data set not listed contact the DARS applications team.
