yes you can take supplimentry bonding from the bathroom light cpc or light switch providing it has a cpc to pipe work etc allthough accoring to the 17th edition if everything in a bathroom is on a rcd and all pipe work in the room has good conterniety between them you do not need to supplementry bond if you need to supplementry bond you should use 4mm cable. what job are you doing in the house because if you havent done anything to do with the bathroom you dont need to worry about it

There is no dual RCD board, only a Main switch side and rcd side. so no rcd protection in the bathroom. Customer is worried it wont pass a test/inspection.

Supplementary bonding and RCD protection on bathroom lighting is not a failure on a PIR.

However, if there is a spare way on the RCD side of the CU then move the upstairs lighting circuit (or whichever circuit bathroom lighting is on) to that .

This then sorts out both probs.

hi there

check weather you water pipe coming into the proerty is plastic if it it there is no need to bond the bathroom RCD protct needed etc all other metal services need to be bonded see 701.415 in the regs book

supplementry bonding is for additional protection provide you have ads automatic disconnection of supply
