Ragnor: Government financial incentives almost always create unintended perverse incentives, see Australia for an example for fraud and failure associated with their heating and insulation program.
I bet the same thing is already happening here, just won't come out for a few years.
Look here for scams with insulation. the govt funding available installations will always come up about the subsidy amount above the same stuff from a non accredited installer.
Really annoys me the subsidys for improving assets.
govt messing in things is just wrong, so I can see that if they start to require home wiring that there will be all sorts of pointless inspection processes needed to get sign off for a service that will be of little interest to loads of people.
