    Ide say the installation is PME you can clearly see the house green/yellow going into the neutral block.



    It looks to me that the block with the G/Y wires isn't a N block, but a simple PE block - there are three incoming cables, two go to the cutout- the third to this extra block  I agree with Mike, it looks like TN-S to me. I have seen similar (although single phase) in a very quiet backwater of West Wales some time ago where the main run of overheads had three conductors - the bottom two only joined at the transformer.
