Hi Ian,
Big orgs arn't the only ones at risk from government fickleness. The Home Inspectors are disgruntled as the HCR is now voluntary. The energy assessors are disgruntled when they announced the phased HIPs rollout with 2 and 1 bed properties nowhere in sight and mortgage payments piling up etc.
Yes, it is a volatile market and a big risk for big orgs that have to invest in training and infrastructure etc. Thankfully we're small enough to cope with any (reasonable) legislative changes that may occur. It is a cost in the property chain but its not a new cost - all the HIP docs bar the EPC already exist and have to be paid for, the person paying has just changed. Arguably its swings and roundabouts though as most sellers are also buyers. First time buyers benefit best of course like I said.
Regarding watering down, you can still get all the documents now that you could before. I assume you're referring to the HCR? Its a voluntary document now as I said. I'm sure you know most of this but I'm posting here for the public to read to better understand HIPs - you wouldn't believe some of the calls we get!
Yes its a difficult time for some agents, particularly the ones the FSA get their teeth into for flouting the HIPs rules. Some are being taken to task as we type. Alot of agents are a bit worried now actually - some say the large pack providers will end up dictating how HIPs will work rather than the other way round. Smaller companies like us are attuned to this and so are quite happy to take their business by catering to EA needs :) Interesting times we live in. Should settle down soon enough though.
Happy to help.
