Is it just me being unlucky but nearly every property I go to (domestic) does not have a decent incoming earth?

Most of the time its TN-S (obviously TT having a spike) but the last 8 domestic properties (in the space of 2 months - different areas of Johannesburg) I have been to have been to had no, or insufficient, incoming earth.

High loop test readings every time. Have two loop testers so its not the testers (checked them on my own place which I know is earthed)

Is this just going to be the norm now. Works fine but no earth?

The old 'I got a COC when I bought the place'. Most have been bought recently so there must be the usual 'from the bakkie' COC thing going on.

Hate doing domestics but you gotta do what you gotta do when the commercial front is quiet.
