Did you notice how gas installations are often done?

Service pipe comes out of ground at front boundary, goes across front
garden at about 2m above the ground unsupported. Meter is hanging in
mid air.

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

It is, but when the horizontal length is about 6m, and the meter is
dangling about half way along this over the front lawn with a noticable
sag....
