Will I need to pay for storage of multiple copies of the data?

The master copy of data is held by UK Biobank at no cost to researchers. You only pay for storage of data that you create or upload into the platform. 

Please note that storage charges apply to any copies or derivates of the master dataset including filtered cohorts, subsets, and extracts. Projects can be shared between multiple researchers on the same application, so multiple copies of derived data are not necessary. 

Please see the costs for compute and storage here.
