You've lost me here Midwest, what's 528 got to do with it?.
Apologies, did misinterpret your post.I completely agree mate. I would bond the internal copper even if it turned into plastic as it exited the building. However, I thought wire puller was getting at the suitability of the main gas bond to carry large fault currents, and presumably because he was stressing TNCS he meant if the neutral (and hence main earth) was lost the pipe route was not reliable, but if it's plastic outside it won't anyway will it?
none required mate. Not sure if this is all worth getting worried about, as others have said. The pipe works all connected at the boiler anyway and any part of it in any installation could easily be disrupted by plumbing activity. How many people have ever seen or heard of a neutral being lost anyway??Apologies, did misinterpret your post.
seems logical to meIn my own house the CU and boiler are in one cupboard, the gas meter in a separate cupboard on opposite side of kitchen and incoming water at other end of the room. On my last Elecsa assessment I asked if i could bond from MET to the gas at boiler and onto water at boiler and confirm continuity to incoming water and gas and the assessor said put note on cert and all would be fine.

I don't have a regs book handy either....but I am certain this applies to supplementary bonding only, not main bonding.
