Are office building allowed to Charge over government rate for electric

[MaiLou]

I am currently looking to rent an office here in Pattaya, the landlord wants to charge 7 baht per unit, is this normal?

 

I know that a law was passed to prevent this on residential buildings, but i am not sure how it stands with commercial rental locations. 

 

I also know that the landlord lives in the building, so is the building residential or commerical, does the deed state that its residential or commercial?

 

Could someone let me know what i should do / ask to get the right rates?
