Well let the facts speak for themselves then:
1. Average time to exchange of contracts from acceptance of offer has reduced from 82 days to 52 days since HIPs were introduced.
2. Transaction failure (between acceptance of offer and exchange of contract) has reduced from 28% to 9%
3. Consumers are being saved an annualised £150 million in aborted transaction costs (I concede the figure I gave previously was too high)
4. In addition to this the inclusion of searches in HIPs has resulted in an annualised saving of over £25 million for consumers (and this takes account of ‘double searching’ in a minority 25% of purchase conveyancing cases).
5. ‘Exchange ready’ packs of which over 30,000 have been issued have resulted in average time to exchange of 35 days.
6. EPCs in HIPs have resulted in real carbon emission reductions according to the NES report issued in late 2009. If there is no formal framework for the EPC (such as the HIP) evidence suggests non-compliance will soar and carbon emission reductions will be lost.
In which case, if they are that beneficial, the market will keep them without legislation. If they vanish, then they are not as useful to most as you are pretending...
