The expected sensitivity, using statistical errors only, to the branching fraction of Higgs to invisible is given for the ZH process at the Future Circular Collider running at sqrts=240 GeV with a total integrated luminosity of 10 ab-1. The decay of the Z to electrons, muons, b-quarks, c-quarks and lighter quarks was investigated. It is found that a 35% measurement is possible if a Standard Model branching fraction of 0.106% is assumed. The Z -> qq channel has the best sensitivity. Additional new physics Higgs to invisible decays could be observed with a sensitivity of greater than 5 sigma if the branching fraction exceeds 0.18% or could be excluded at 0.07% at the 95% confidence level.
