It is with much sadness and with absolutely no desire to see a tragedy, I await the first multiple fatality from these converts to electrical installation work, gas explosions by their nature are seen to more news worthy as happened recently 3 or 4 houses gone, luckily I believe no deaths, the problem is that they may be competent at point of exam and annual inspection, but they have bigger fish to fry ie fitting kitchens and bathrooms etc, and I don't believe that a lot of them can give an electrical installation and the responsibility that goes with it, all the time such a potentially invisible deadly killer deserves, I hope I eat my words and no one dies...but I suspect I wont..
