Default boiler earthing?

Where is the boiler? Where was it in the last place?

Generally speaking you would expect to see supplementary equipotential
bonding in places that pose an special risk (bath / shower rooms, pool /
saunas etc). There is no harm in have supplementary bonding between its
connections, however there is in many cases no absolute requirement for
it. Note that supplementary bonds do not need to be either earthed, or
connected back to the main CU earth terminal.


It is in the kitchen, exactly where the old one was. Thinking about it
it's all copper pipe around the boiler but after 2 metres it turns
plastic, so I'm not sure that bonding would do much, except in the
immediate area of the boiler.

Is supplemental bonding supposed to be 10mm^2 too? I am not going to
do it (unless you tell me otherwise) but I ask out of curiosity.

Thanks.
