At that monthly cost I would suggest buying an energy monitor for each of the three CUs.. they only about £30 each. And you /client can use them afterwards too.
I assume RCDs are fitted to each CU? This would trip if any earth leakage. If fitted, I would suspect faulty meter. Get elec company involved..
