Hi,
I have read the building regs and various forum posts on this topic but remain confused. Please could someone confirm if I have reached the right conclusion about supplementary bonding in this scenario:
All pipework in the bathroom is plastic (bath, shower, sink, toilet), except for a towel radiator, which is supplied with copper pipe with plastic push-fit joints.
Electrics are a pull switch to downlights (outside of zones) and an extractor fan (outside of zones) with its own triple pole isolating pull switch (outside of zones).
Am I correct in thinking that no supplementary bonding is required as there are no electrics within zones 1-3?
Thanks very much in advance for help on this confusing topic.
