How to check whether there are tenants stealing electricity from the property?

Although what you said is incredible at first glance, it is not impossible to think about it carefully. The property is a public place, so if the electricity consumption is too large, there must be a problem, so you must find the cause of the problem. If you want to find the electricity stolen from the property, you can ask the electric power bureau when the electricity consumption is relatively large. Is there any difference between the working hours of your property during this period? If it's really different, you can be sure that someone connected the line privately. If so, you should check the circuit carefully.
