What to learn from the Australian EPC?

Here is an Australian Energy Performance Certificate. You can compare the UK version here. Some obvious differences are:

• More, small scale / easy recommendations (good)
• Includes water efficiency (good)
• Linked to a govt loan programme (good in principle)
• Happy-smiley design (bad!)

Oh, and wait a minute - worth mentioning that the Australian government pays ~£120 for each certificate. Sounds good, but in practice it's been a nightmare for everyone involved. The $10,000 loan element has since been withdrawn - too expensive and too complicated, apparently. A lesson for any new UK government thinking of launching a similar scheme.
