It is quite common in recent big installations to have metering for all sub-boards so the building consumption can be better understood, but that is separate from billing metering (though I guess some companies use it for internal overhead allocation).
All of the main suppliers of industrial style boards offer metering kits, and also remote access options so they can be centrally monitored (if no one willing to wander round and check from time to time).
Beyond the moitoring of electricity costs, they are useful to understand demands as most of the board meters (not the cheaper dedicated billing sort) support measuring min/max demand, per phase, etc, so if new equipment or building reuse is planned you have a good idea of what impact it might have on the existing boards/sub-mains/etc.
