Inadequate inspections on the safety of wiring in buildings across England are increasing the risk of fires, E&T has found. A flawed regulatory system has sparked a race to the bottom, with some businesses profiting at the expense of the public’s safety.
Please get in touch with any comments/thoughts you may have
Andy and Zoom, It is rather disingenuous to suggest I am a dinosaur because I say fitting a single RCD (not none as you seem to suggest) is an easy and cheap way to significantly improve an installation. All your customers may have a grand or two they don't need and you do, but with the present situation of the economy you are going to have to think again. The regulations say nothing about fitting multiple RCDs except to suggest that inconvenience should be considered. The next inconvenience will be having serious power cuts, or being cut off because you cannot pay the present astronomical charges. If all properties were completely rewired, would there really be a change in the electric shock statistics, I think it would not be statistically significant. You seem to have a serious problem with any risk, life is a risk, and there are many things you can do excepting electrics to reduce those risks. About two-thirds of deaths occur in bed, do you suggest we eliminate beds? It would be much more effective to stop people eating too much, driving, riding motor bikes and cycles, or even the very low risk of traveling by air. You must find life horrific to contemplate. If the lights go off in winter due to an RCD trip, surely one finds out why? If you have a stack of RCBOs you probably don't even notice, which is a snag if it is the freezer or shed. More is rarely better! More circuits is better, probably not.

Are you just considering able bodied active people that may be affected by your one R.C.D. that disconnects everything in a house David? Why are you retrogressing back to the 80s?What about disabled people, elderly people or people with mobility issues, children and house visitors such as baby sitters that may be affected by the blackout. Could they all cope easily without panicking? Would they know what to do to get the mains back on. What if the one and only R.C.D. would not reset?

I don't agree 100 %. It wouldn't be viable, because it's not unusual to see 5-8 mA of protective conductor current "standing" in the installation, which increases in winter when cold concentric mineral-insulated heating elements switch on (ovens, grills, washing machine, some tumble dryers), and not considering "surge protective conductor currents" ... and when more lamps are placed with LED, etc., things will only get worse.
Making something "pass" is one thing, but making a usable installation is another thing entirely.
I think there will be a lot of people in the industry who think a minimum of 2 no. RCDs would be required to prevent unwanted tripping in modern houses (one RCD for some flats, on the other hand, might get away with one as you say).
