I am ina 200 year old building split into 4 flats. The mains services come in through the communal cellar. The incoming electric supply has a large cable split into 4 fuses which then feed the four flats individually.
Qestion 1 - The earth from this area goes into a large henley block. Is it within regs to bond the gas and water supplies to this earth rather than trace it up through the buidling and into the CU?
Question 2 - The meter for the flat is in the flat its-self. The old fuse board at the moment doesn't seem to have an earth connection but there is evidence of a sheath clamp just below the meter. Should I try to run a 16mm earth cable back to the Henley block in the basement or call in the supplier?
