  We study a class of non-exotic minimal $U(1) '$ extensions of the Standard
Model, which includes all scenarios that are anomaly-free with the ordinary
fermion content augmented by one Right-Handed neutrino per generation, wherein
the new Abelian gauge group is spontaneously broken by the non-zero Vacuum
Expectation Value of an additional Higgs singlet field, in turn providing mass
to a $Z'$ state. By adopting the $B-L$ example, whose results can be recast
into those pertaining to the whole aforementioned class, and allowing for both
scalar and gauge mixing, we first extract the surviving parameter space in
presence of up-to-date theoretical and experimental constraints. Over the
corresponding parameter configurations, we then delineate the high energy
behaviour of such constructs in terms of their stability and perturbativity.
Finally, we highlight key production and decay channels of the new states
entering the spectra of this class of models, i.e., heavy neutrinos, a second
Higgs state and the $Z'$, which are amenable to experimental investigation at
the Large Hadron Collider. We therefore set the stage to establish a direct
link between measurements obtainable at the Electro-Weak scale and the dynamics
of the underlying model up to those where a Grand Unification Theory embedding
a $U(1)'$ can be realised.
