*gas cylinders will clash with the fibre coming into the build, as it's most likely going to be in the exact same spot. Does not comply.
This is such a stupid rule, the ENT is in no way an ignition source is it?
EDIT: Regardless this is a rule, and I had to do some very precise measuring to get our gas bottle placements correct, and was forced to move where the services enter the building. But at the end of the day, if your building company is handling everything then it's their problem to figure out and resolve.
