We didn't accept your idea of "the truth" the first time you wrote it - merely repeating it ad nauseum doesn't make it any truer now than it wasn't before.I know that if someone decides, in advance, that their whole design philosophy is to take an existing installation and deliberately make it more dangerous than it already is then they cannot possibly have been reasonable in your provision for safety.
If you think that the law does not agree with that truth then your reading of the law is flawed.
If you think that the Secretary of State's advice does not agree with that truth then your reading of the advice is flawed.
And you are approaching the whole topic with a belief that the current technical and legal framework in place is unsafe - whereas it seems everyone else believes that it is reasonably safe. There is a saying that if all the other soldiers on the parade ground are out of step with you, it just might be you that's out of step Once you reach a level of reasonably safe, then it's fairly moot whether one option is very slightly more or less safe than another if they are both reasonably safe. If you don't believe the current technical and legal framework is reasonably safe, then take it up with those who put that framework in place - I'd love to be a fly on the wall with that conversationYou are approaching this whole topic with a belief that it is reasonable to unreasonably choose to deliberately make an installation more dangerous than it already is.
So far as I recall (and I'm not going back through 5 pages to double check), in this thread you have not answered the question of whether you believe an installation/work done on it is reasonably safe if it is done in accordance with the technical and legal framework in place (ie BS7671, Part P, et al). It's a simple yes/no answer which you seem reluctant to answer.
