its your property, do your due diligence. always spot check tenant. simply collect rent, then bark like dog when get penalised.

it is not tnb or any other agency responsibility to bear that cost.

we should follow uk style la

no pay u get switched to prepaid

Bill racked up by tenant from July to Dec same year. Means maybe something like this:

3 month see high usage but meter not matching trigger flag under TNB.
1-2 month finding out which unit under that substation consuming very high electricity.
1-2 month verifying and calculating backpay and billing owner.

Initial bill amount was 1.7mil for July-Dec (283k average per month if 6 month).
Even if they settle and find out within 2 month also you mau pay if kena bill for 500k+?

The loss is not tracked because it bypassed the meter...

TNB can detect, just there is a time delay
Once they calculated the stolen amount then they slap the owners with the bill
