I live in an over 50s village consisting of around 250 owner occupied homes. Each of these houses had good quality roof insulation installed during construction. That hasn't stopped unscrupulous house insulators flogging ceiling insulation to approx 200 homes in the village.
The way they operate is to convince the home owner that they need additional insulation and that it is free. They come around with vans and pump the insulation through an opening in the roof. The operation takes about an hour. They then get the owner to sign a document to say the work was done, and they claim $1600 from the government.
These houses are all small two bedroomed with a carport which does not have a ceiling. I estimate they could do the job for $400, which means in this place alone they are ripping off $1200 on each house.
The whole stimulus package has been a godsend to dodgy tradesmen, rip-off merchants and bottom feeders.
Still it is achieving what krudd wanted. The money is being spent quickly, even if most of it is being wasted.
