We address the phenomenological impact of a well-motivated class of scotogenic models regarding flavour and electroweak precision observables. For the case of a ``T1-2-A'' variant, we carry out a full computation of the next-to-leading order corrections to leptonic Higgs and $Z$-boson decays. We revisit previously drawn conclusions on operator dominance and constraints on the parameter space in view of the evolution regarding $\Delta a_\mu$. Finally, we consider the role of $H \to \mu\mu$ decays (and other flavour conserving Higgs decays), as well as precision observables in probing this class of models at future colliders.
