Is insulating material an alternative to bonding in any other situation?

Potentially in very situation I would have thought - if it's insulated or otherwise out of reach it can not longer introduce a potential (at least at that point) so it's no longer an extraneous-conductive-part so no longer needs bonding.

Do the gas people know about electricity, well that is for you to decide?

They might equally ask the electrical industry really think it's a good idea to implement PME where diverted N and open PEN currents are shoved down pipework carrying flammable and potentially explosive gas, and whose continuity necessarily has to be broken on occasions during maintenance.
