That's why I said: compulsory or not. Especially on systems without a rcd, I find it really reassuring to know that whatever happens, any metal part is guaranteed not to be carrying any voltage. What does it take? 15 minutes and a couple of quid in materials.Bonding of kitchen sinks and taps used to be in the 15th,and was removed from the 16th(first one being yellow edition if my memory serves) onwards

No your memory does not serve it was red
has anyone mentioned that some boilers incorporate earth bonding into the jig/standoff bracket?
Jig of WB for instance connects the pipes by means of the metal bracket used for pre-piping if you want to call it that. 0 Ohms if you measure between any of them. The cpc of the mains connection is also linked to the boiler casing.has anyone mentioned that some boilers incorporate earth bonding into the jig/standoff bracket?
No, didn`t know that, how does that work then?
Main or as it is now 'protective equipotential bonding' is required to be connected to central heating and air conditioning systems (and others) as well as the gas and water pipes. reg 411.3.1.2

Would have done little good, you need a multifunction meter for that as you have to measure to 10 mOhms accurate. And technically speaking, impedance at 50Hz rather than resistance; not that that would make a lot of difference on thick, straight single-core cables or a jig.Jig of WB for instance connects the pipes by means of the metal bracket used for pre-piping if you want to call it that. 0 Ohms if you measure between any of them.

Wow, that`s super, all them damn boilers I have installed without testing the jig with my multimeter, Damn it!
