Obviously you consider RCD protection (additional protection) to socket circuits the most important possible difficulty with an installation, therefore a C1. That line in the regs. does not quite mean that which you suggest. There is a limit to how much stupidity can be avoided unless you change all supplies to SELV, preferably 12V. Most people today are aware of RCDs (trip switches and many other names may be used by clients) and many people have extension cables with RCDs built into the plug. Imagine for a moment we were making regulations about car sales. I suggest that all cars should be limited to 70MPH and when it rains only 40 MPH, by their built in computer, and just for fun 50 MPH at night.. This might appear "safer" but would be ignored as unworkable. Where you are going is not much "safer" at all, and cars cause many times as many deaths as electricity. A reasonableness test must be applied, and finding every installation in the country does not meet the current book is not reasonable. How many deaths have ever happened from cooker sockets without RCD being used outdoors, and even more important without the user being negligent in some way, eliminating cutting the lawnmower cable or dropping the hedgecutter in the pond and not switching off before rescuing it? It would need serious research but I suggest that the number may well be none. I tested a cordless kettle a couple of weeks ago and found the socket in the base and the kettle failed to connect the Earth to the all metal kettle. I suggest this in reality this is many times more dangerous than the cooker socket. Should cordless kettles be banned? Should they all be class 2 (difficult)? Probably not but risk is part of life. No one has managed to eliminate it yet, unless keeping everyone in bed and then there could be an Earthquake or Virus. Fire in the home is many times more dangerous than electricity, why not condemn all homes which are in any way flammable, including contents. Life would be simply terrible in a cave without a fire.
