The NT listed waste schedule reaches further than most people expect. It covers clinical and related wastes, grease trap waste, septic tank sludge, waste pharmaceuticals, waste mineral oils, asbestos and tyres, so a licence is needed to cart any of them for fee or reward.

Changing the layout of a wet area inside an NT building control area needs a building permit. Putting a shower where a bath was, moving or removing a partition, cutting new pipework into a wall or floor, enlarging a window, or installing a fixture where none existed all cross that line. Like for like swaps, unblocking, leak repairs and retiling do not.

Thermostatic mixing valve work in the NT can only be done by a licensed advanced tradesman who holds the thermostatic mixing valve endorsement. Ask for the endorsement, not just the licence.
