Hi
We have advice on the http://property.laystar.co.uk web site on HIP issues.
I understand the resentment of a home efficiency report, it seems nonsense. Originally the Home Condition Report (mid-way survey) was to be compulsary, which of course would have been more use to your average buyer. Seems the gov got scared off on this issue and settled for something which would be more useful to gov stats than a buyer.
Anyway, the HIP official website has now been enhanced, thankfully, and it explains what is meant by 'on the market'. And yes, being on the market is about being to prove just that, but i think it has to be continuous. A one-off paper ad is not really continuous marketing.
By the way though, you could market continuously with LayStar right now for free. We're filling the books so get in quick ;-)
Best wishes
