If the new regs really do mean that you have to use 'qualified' tradesmen for even comparatively simple tasks like the original post. why can I walk into B&Q, FOCUS, HOMEBASE, and even the local hardware shop in my village, and buy 15amp t&e cable, switched and unswitched outlets, and replacement 13amp outlets ? Surely they should only be available to people with 'proof of qualification' to handle and install them, or at least come with a 'health warning' about meeting these regulations ?
