Just because there's a PME head there it doesn't mean the link is there mate. I though TT because there's no cable going to it

Apart from the grey one I wouldn't have said they were PME heads, the black ones with added earth terminal are normally found on split con TNS supplies around here.

I'm pretty sure the DNO would not have fitted the earth terminal if they weren't providing an earth.

This is how my flat is supplied. Although it is fed the main incomer in the basement which is TP&N, PME.
