Did you notice how gas installations are often done?

Service pipe comes out of ground at front boundary, goes across front

Although AIUI all installation pipework has to be in screwed steel, rather
than soft-soldered copper as here.

yes that does seem to be the case, screwed steel for gas. they do
suffer earthquakes quite a lot and maybe this is to reduce the danger
of pipe fractures.
