The LHeC and the FCC-he offer unique prospects for the measurement of top properties in energy frontier, luminous $ep$ scattering. An update of the 2012 Conceptual Design Report was produced last year . In this talk we will revisit the determination of the top mass through inclusive measurements. In addition, we will address the possibilities for precise measurements of $Wtq$ and $\gamma tq$ couplings, and competitive searches for FCNC top couplings.
