And it has stopped the man in my village who is a professional electrician (industrial, therefore no Part P) from helping his neighbours (because none of them want to cough up 100+VAT for a BNA). So would they then go and get cowboys in, or start clipping extensions to the skirting? I doubt all of them will go and employ a NICEIC electrician.
I've seen his work in his own house - it is outstanding. Higher quality than usual (for domestic) CU, impeccible cable runs, properly run external supply to garden, etc etc.
