gas pipe running underground , what are the regs?

[mike-]

I have no intention on doing this myself as i am a joiner,
i would like to know any cons to putting a propane bottle to cooker gas pipe underground appose to having it running around my house wall, ?
just some advice on the regulatons and the extra cost on materials would be much appreciated?
i would assume it would have to go in a protective sleeve?
does the cold effect gas like it does water?

thanks
Mike

Fine if done right I would say get a lpg gas engineer out to price for the works

No reason why it cant be done but you will need to employ a a GSRI who does lpg cheers kop

Yes it can be done, needs to be a min depth and other rules to apply depending on distance may be a idea to use TracPipe (S/Steel) flexible and would be NO joints under ground
