If it is electronic meter, there is no need of testing it in laboratory. U can also check whether it is OK or not by counting the no. of pulses for one unit.
Actually, the people should be educated about the meters which are correct. It is wrong perception of the people that the meters are recording high consumption.
If earth fault is there in the wiring then also the meter will record. U can get your wiring rectified and then your energy consumption will come down.
