That 'interesting discussion' is nothing of the sort. It is a collection of comments from people who have already decided that any form of legislation is wrong and must be removed regardless of whether it is appropriate or not.
Whatever the comments say, the initial description on that discussion page is totally wrong.
Part P was introduced on the pretext that it would save lives
Not true.
it has cost householders lots of extra money to have electrical work done
Plenty of electrical work is not notifiable, so no additional costs there.
If people have notifiable electrical work done in their home and use a scheme member, the additional costs will be tiny or none.
If someone wanted small notifiable works doing, and for some reason chose a person who was not a scheme member, and then paid the LABC notification fee, then there will be an additional cost. However this is a small percentage of works done, and it is likely that such people wouldn't bother or care about notification anyway.
it has driven many one man electricians out of business since they can't afford the charges
Scheme membership fees are less than £500 per year. If a person operating an electrical business can't afford an extra £10 per week, they were already out of business.
has driven electrical work such as the installation of consumer units into the hands of larger companies who can afford the registration fees
All lies. Even if someone was not a scheme member, paying the notification fee for major works such as a new consumer unit or rewire would only be a small percentage of the total price.
Most of the comments there are wrong as well, or have suggestions which are totally ludicrous. On the second comment, someone suggests that 'Most DIY electricians are competent people & do a safe & tidy job'. Clearly they do not - just look at this forum for plenty of examples.
The rest of the comments are mainly people complaining about huge costs and other problems which do not exist, irrelevant complaints about other legislation and a selection of people who want to scrap all building regulations, make them optional, leave the EU and so on.
