[Closed] Gas plumbing question,

So a customer wants a new gas fire connected to the existing gas pipe which runs on the wall, he wants the gas pipe buried under the plaster and totally hidden, along with no connection showing to the existing pipe, that comes out of the corner of the wall, told him to just box it behind some skirting, so its easily accesable, but he wants it plastered into the wall, and hopefully a tv or phone engineer will never knock a nail into that part of the wall.

Oh and i want be doing any work on the gas pipes.

Can you legally run gas pipes buried in plaster.
