Bob H:
Hi I rent a bungalow and have a contractor appointed by my M A classing my 30 year old installation with a split board with a C3 for not having any SPD, I understand why. They have to test against the 18th Edition. And C2s for having no RCD protection on 3 lighting circuits, even though the place is bristling with main and supplementary bonding. I’ve tasked the contractor to come back and test properly to confirm the earthing is fit for purpose, having quoted £400 plus vat to rectify C 2s and C 3. Daylight robbery in my view. Am I wrong..
Bob H, welcome to the forum and no, you have every justification for being concerned.
C3s do not have to be rectified.
Until the 18th Edn, lighting circuits did not have to have RCD protection. That's a C3, not a C2, assuming that they have a circuit protective conductor. (That's an earth to lay folk - they didn't always have one, but they would have done 30 years ago.)
