  The large and growing library of measurements from the Large Hadron Collider
has significant power to constrain extensions of the Standard Model. We
consider such constraints on a well-motivated model involving a gauged and
spontaneously-broken $B-L$ symmetry, within the Contur framework. The model
contains an extra Higgs boson, a gauge boson, and right-handed neutrinos with
Majorana masses. This new particle content implies a varied phenomenology
highly dependent on the parameters of the model, very well-suited to a general
study of this kind. We find that existing LHC measurements significantly
constrain the model in interesting regions of parameter space. Other regions
remain open, some of which are within reach of future LHC data.
