Hi- I'm burying mains cables in a brick wall, before a nice Gas Safe man runs a new gas pipe to a cooker. Am I going to cause problems here, as I believe gas pipes must not be nearer than 25mm to circuits, and the pipe will be running across my vertical cable runs? Is there a way around this for the regs. such as the cable being in plastic tubing in the wall for extra insulation, otherwise I'll have to dig really deep channels? Thanks.
