There is no traceable uncertainty associated with each datum in the ERA-Interim reanalysis.
However, in ERA-5 there is an ensemble. This multiplies the data volume, but it means you can use the spread between the ensemble members to get an estimate. See ERA-5 page. ECMWF want us to use ERA-5 now anyway.
