Individual Appliance Monitors (IAMs):
The IAMs do not have to be professionally installed. Simply plug them in and away you go.
Although the Senseable transmitter and CT clamps are not intrusive (this means that no electrical connection is made), due to liability reasons we insist that a professional electrician must perform the installation.
In the UK, non-professionals install the transmitter, but we are afraid this cannot be permitted in Australia.
In NZ, non-professionals can in some circumstances install the transmitter. This link should help out with that.
