I only just found this question so I hope you havent signed up for training by now.
I qualified as a Home Inspector in the same time as the Government did their u-turn on Home Condition Reports and as yet have not been asked to produce one report. I am getting by doing energy reports but despite reading countless articles about being able to earn �80K am lucky to get �45 for an EPC. I am a qualified estate agent and so have plenty of contacts for work but there are loads of people out there providing the same service. It will be a long time until I recoup the �10000 it cost to train.
In short, dont waste your money on the training.
Also many clients are reluctant to give work to people who have changed careers from say a butcher to an energy assessor because they feel that they do not have enough technical and industry knowledge and I have to admit many of the people I met whilst training were complete muppets that had been seduced by the thought of huge salaries.
Im not usually such a negative kind of person!
