We investigate the prospects for discovering the Flavour Changing Neutral Current (FCNC) tqh couplings via the process 
at the proposed High Energy Large Hadron Collider (HE-LHC) and Future Circular Collider in hadron-hadron mode (FCC-hh) including the realistic detector effects. The relevant SM backgrounds are considered in the cut based analysis to obtain the limits on the the branching ratios of 
, followed by the leptonic decay channel of the top quark and diphoton decay channel of the Higgs boson. The upper limits on the FCNC branching ratios at 95% confidence level (CL) and the 
discovery reach for the different integrated luminosities are obtained. It is shown that at the 27 TeV HE-LHC with an integrated luminosity of 15 ab
and at the 100 TeV FCC-hh with an integrated luminosity of 30 ab, the BR(
) (BR(
)) can be probed, respectively, to 
and 
at the 95% CL.
