We just had something similar done in Adelaide. First, someone comes over does a free energy audit, replace shower heads, install power boards that automatically turn off equipment on standby, block off unused fireplace chimney, replace light globes with fluoros. With our 27 down lights, a sparky came back later, replaced globes with 6watt LEDs for $5 each, replaced 4 transformers for $10 each. They seem brighter than the old halogens, very happy with the service, even better if it was totally free though!
