Only the CPC of the socket circuit on that floor (since this feeds the boiler, which has its pipes supp. bonded, and I have linked the tap pipes to the same block).
You're right, I haven't bothered doing the lighting circuit of that floor as I would have done in a bathroom
There would have been some risk of PEPs anyway since the gas and cold water pipes are main bonded (though they are included in my Supp bonding as well)
I am worried poor Nigella may need resuscitating after I get her wet and naked (if only).
