I have bonding across all pipework on my combi boiler - the bathroom is just above the kitchen (where the combi is) - do I need to bond the bath, taps and sink taps ? or any other metal parts ie metal towel rail and toilet roll holder.
And do I need to do it with huge great 4mm - or would something smaller do.
Have a ELV fan in Zone 1 only, downlighters are above 2,25mt so not in a zone.
