The problem is Willie that the registration process does not give any such safety net - not in my experience anyway.
What it does is invalidate my five years apprenticeship and my half century's worth of practical experience on the tools, and replaces them with a certificate for being able to pass exams.
The old apprenticeship scheme guaranteed that any tradesman had undergone at least five years practical experience (which is not the case with registration) and any customer asking for more was fully entitled to demand a City and Guilds or Higher National Certificate, and there are enough voluntary Guilds for a tradesman to register with.
My objection is that towards the end of my working life I was required to go back to school, then pay highly for the privelege of continuing to work at a job I had spent most of my life at - stuff that!
