Accessing the data

Containing billions of person-based records, SAIL Databank is a rich and trusted population databank. Following application and approval, it provides researchers with secure, fully linkable and anonymised data that can be accessed and analysed from anywhere in the world. SAIL can also anonymously link new data uploaded by users to existing routinely-collected data within SAIL (subject to approvals).

SAIL Databank has established a convenient and effective two stage application process for researchers who would like to access data via the SAIL Databank for high quality research projects.

Costs are dependent on support and infrastructure needs related to your project (such as time for data preparation and use of computing resources). In practice, this means that there is a cost for most projects. This varies based on the complexity of the project, the support you would like from us, and the type of funding. These costs are detailed during the scoping process. Find out more.
