Testing block of flats

[s6stu]

Hello,

Couple of questions, firstly does each flat require it's own dedicated earth to the main incoming on the ground floor of the property, zs readings are fine with the 10mm 3 core SWA that has been used. (never certed a block of flats before, jus wanted to be 100%)

And, there is a heater in the bathroom that only has it's own pullcord isolator, does this require an FCU outside of the zones?

Thanks in advance

I would assume,that one of the cores in the SWA is being used as an earth/bonding conductor?
If so, a separate earth is not required.
How is the heater fed, is it spured off of a circuit, or is it on it's own circuit?
If it's on it's own circuit, then an FCU is not strictly neccessary.
