DNO requirement for protective bonding

It is very common in NI for NIE to refuse connection to a domestic installation unless main protective bonding is in place to the water service pipe, even when it is the blue plastic type. Sparkies have to fit a copper insert in the plastic pipe to install the bonding clamp. 
I cannot imagine why they insist on this, but insist they do! I was wondering if anyone has similar experience in other regions.

  • That said, what about the argument that to leave the internal metallic pipework unearthed

    In the vast majority of cases the internal gas pipework will still be earthed via the boiler or hob (igniter) c.p.c. - so omitting main bonding usually makes no difference on that score.

  • In which case Andy, it begs the question as to why hundreds of metres of 10mm singles are thrown into installations across the land with each rewire carried out. Why bother when you can just utilise the 1.0mm/1.5mm cpc from an appliance metallic pipework to the incoming gas & water supplies!

    With the extensive use of plastic pipes internally these days for hot/cold water, and central heating systems, it's a wonder that there is still a requirement to bond at all these days.
