Safety Check Weirdness

[John D v2.0]

Earth. This runs to ground outside of the kitchen. He tells me that although this is only NCS for a gas check, he is a qualified electrician. He then tells me that the hob should have a 3 amp fuse on it, and to install the fuse, he will have to re-route the gas earth.

The earth is an NCS. No work required.

His problem with the earth made no sense in the first place. Presumably the bit outside the kitchen is the earth rod and it's a TT system, but that's none of his concern.
He may be concerned about bonding of the incoming gas supply, but all he can do is advise you to contact an electrician who can then test if the internal gas pipe is extraneous or not, and bond if so.
If on the other hand he is saying that the gas bond happens outside rather than inside, this is ok as long as the connection and cable is suitable for the environment. It should be at the point of entry whatever that means, but that contradicts the gas regs which say within a certain distance of the meter.
Either way it doesn't seem clear what he means.

I have sent three emails to Vaillant with pics asking them whether the flue is legit or not but not yet received a reply. It has been installed horizontally as per the manual and has never failed a check so I am assuming it is ok. Sent the same pics to Gas Safe. They aren't interested

you'll be lucky if they say its legit
