Brain fart - bonding gas from cylinders

[littlespark]

Does a copper gas pipe, coming into the house require bonding when the pipe is being supplied by propane cylinders, via rubber hose.
Doesn’t go underground at any point.

The water pipe is bonded, and therefore connected to gas at the boiler, which is at the point of entry of the gas…. Can’t be any more than 1m of copper pipe on the gas system.

Customer is getting a company to fit an EV charger, and I don’t know if they’ll be of the ilk that…. “ if it ain’t bonded, we ain’t fitting it” without actually looking at the situation.

I’m also concerned the EV fitters will just run a rubber flex round the house at low level to the driveway… The outside wall being against someone else driveway… SWA more suitable, or am I just prejudiced against EV engineers like I am with meter monkeys.

It won't be an "engineer"

I wouldn't have thought it would need bonding. I can't see it introducing a potential, with just the bottom of the cylinder resting on the floor outside, though a test could prove either way. Diverted neutral currents shouldn't be an issue either.

I always thought that information such as this, and bonding and earthing locations etc would be useful to have on a label stuck onto a CU, instead of mixed colours labels and the like.

411.3.1.2 (brown) still has the note that says not if a non-conductive entry.
