I'm planning on getting the old fuseboard in my house (late 1960s semi) replaced with a consumer unit.
I've noticed that the lighting circuit in the house doesn't have an earth (it's red and black wires in grey sheathed cable).
Assuming the wiring is fundamentally sound, would the new regs require the lighting circuit to be replaced in order for it to be earthed?
If it is the case, is there anything I can do to prevent a moderate job becoming an eye-wateringly expensive one?
