similar thing on a job a few years ago, A N other ran 2x pipes over the top of my box that had been 1st fixed (removing my box and leaving it hanging on the cable)... cut the pipes top and bottom and reattached box... on the next visit a few days later the pipes have been taken a different route...
old victorian house, CU in smallest understairs cupboard, open door and there's a gas pipe right across front of cupboard. Similar scenarrio, lift access hatch to get under floorboards ( small and tightish) firkiin gas pipe across that space :facepalm:
