hi all , went to a property today to install a garage supply carried out zs at nearest socket 208 ohms !,checked service head , just two very old what look like 16 mm cables poking through a wooden board one to a neutral block, one to a service fuse, 2.5 earth cable coming up through floor to MET ..... now before you all scream tt i have never come across tt in my town (fleetwood,lancs ) ever, the service cable must come through the wall from next door (who wasnt in !) terraced housing in my area all have tncs or tns, the property has no rcd protection so have suggested the contact dno to request engineer ( no rcd unit in van and wholesalers shut )last one like this neighbour had new board fitted by friend and had snipped the looped earth from their MET.

I'd go for TNS on a looped service and as you've already said missing from next door

Might be an old water pipe earth below the floor connected to the bare copperconductor.

If memory serves me correct several years ago I had faults presenting themselves in house 1 traced back to faults at house 2 with a looped main. Took me a while of head scratching.
