I've tried to research and form a plan without asking on here, but I'm just going around in circles.
Just completed an EICR. The wiring ranges from new metric colours to old imperial cable.
There are 2 lighting circuits, both containing class 1 fittings. Most of the fittings have a CPC, but there is no continuity to the MET in the consumer unit.
The CU is extremely cluttered and I simply can't be sure if there is actually a CPC leaving the CU with the lighting circuits. I cannot gain access to the beginning of the conductors where they leave the sheath. One of the lighting circuits has imperial cable in the circuit breaker, the other has metric (tinned copper). Meaning the cable is 51+ years old assuming no imperial was used after 1972 and tinned copper being replaced by untinned from 1967-1970
I realise this is clearly a C2, but is the only solution to rewire?
If the wiring system is pre 1966 and no CPC was required, I don't believe there is any requirement in BS7671 to automatically have it upgraded to current wiring standards. Of course there are now class1 fittings. Will removing these class 1 fittings then bring the code to a C3? Again, there are CPC's to most lights, my worry would be that a DIYer would simply put up a class1 light again, even with a danger note on the CU.
I really can't see this being an option, but I just wanted to be sure before I tell the customer they need a partial rewire.
Cheers all.
