I am fairly certain that there was no segregation of client monies. The conclusion you have reached about 2 Scout Lane is not far from the truth that I witnessed in person.
Furthermore, I also attended the insolvency hearing and witnessed the close relationship between the account handler and Espen Jewhurst. I intend to write to the Ombudsman to let them know that it is not overtly professional or advisable to call the insolvent client "'mate" in front of assembled creditors. The conduct of the appointed Partner, Lane Bednash, was slightly more professional, however I am certain that we can demonstrate that the same firm and potentially the same partner have acted for Jewhurst both in 2010 and 2012. This should surely raise concerns with Wandsworth Trading Standards.
As for Protia Plumbing and Heating, who are still trading I believe, thank you for highlighting this interesting information. I can demonstrate clearly that Protia Plumbing and Heating were operating in compass with Protia Design and Build, as I have electronic copy of quotes for elements of the work which they were quoting to undertake (demolition) whilst Design an Build were slated to complete the main build, something which they never did, nor had the opportunity to do before insolvency.
As for where the money went, well whilst this was all unravelling, we had evidence that Espen Jewhurst was in Abu Dhabi and South Africa whilst we were in misery. My wife has been in contact with at least two other clients who were victims of Jewhurst, whilst I have contact with the other client who was able to attend the insolvency hearing.
