That doesn't really surprise me, but it does illustrate how crazy this bureaucracy is.My son and I had to complete a job when the builder disappeared. We did it all above board and informed the LABC what we were doing. They wanted an installation certificate and my son said "I will make that out I have my C&G 2391" at which the inspector refused to accept that. He then said "My dad has a degree in Electrical Engineering" at which they said I could do the inspection and testing.
As it happens I also have a C&G 2391 but they did not know that. And I had no insurance but my son did. Since it was my parents house there was not really an issue as far as insurance went we were working like any other DIY would work.
However it seems very strange as when doing my degree we never touched anything to do with BS7671 and the qualification did not really mean I knew what I was doing as far as inspection and testing goes.
Kind Regards, John.
