Can someone advise on earthing type for the following:-
1950s house, supplier cable (old lead/paper) type - incoming earth to consumer unit attached to sheath on that cable. A second incoming earth to the gas pipe. Other earth bonds made on the other side of consumer unit to various pipes around the house.
Is this TN-S ?
