If i was asked to test some buildings to determin whether the Ze was to comply (dependent on the type of supply) and that i new there was no main bonding in the buildings (due to no water/gas services)would it be possible to take a Ze reading at a socket to see if the supply had a sufficent main earth.

i know the buildings installation should have already have been tested for this before they where energised!!!!!!!
also im not looking for exact figure just need to determine if they comply.
