Having trawlled through old DIY posts I can't seem to get a definitive answer on whether it is acceptable or not.
Basically gas meter outside in plastic box, pipe enters inside under kitchen sink, goes left about 50cm then goes directly upstairs against the wall next to the hot and cold pipes. Can I box all three together. If so can I use plaster board and skim, or is it better to use mdf and screw and paint, incase access is needed in the future.
TIA
