The nonsense, BAS, as you well know, is the widely-perceived notion, held by time-served electricians, that all the bad work is carried out by people who have done nothing more than taken a five day course and have suddenly started trading as 'electricians'.
The truth is that it only takes a simple qualification to be allowed to apply for registration and that this was introduced because a large proportion of people were already carrying out electrical work in dwellings with little understanding. Some of these people have increased their knowledge, and - to the chagrin of electricians - have legitimised their operations by becoming registered. (Others have actually stopped carrying out electrical work.)
The nonsense is that non-electricians - willing to be trained, willing to be registered and assessed - are incapable of doing a good job, while electricians are always perfect.
I don't dispute your list of quite legitimate assertions. What I do dispute is that there are legions of so-called 5-day wonders suddenly trading as 'electricians' because, as many have discovered recently, there is little financial incentive to trade solely as a domestic electrician.
I concede that it is entirely possible that there
are some people out there who were accountants or IT workers six months ago and are suddenly registered to carry out domestic electrical work and describe themselves as 'electrician', but I don't see much evidence that this is rife. Most of those registered have done so in order to maintain their own, pre-existing trade.
So when it comes to:
"No experience, no idea, no clue"?
that applies as much to some of those who describe themselves as qualified electricians.
The truth is that there is and always will be sub-standard work, carried out willfully or in ignorance by people insufficiently aware of their responsibilities or the dangers, regardless of how they have obtained any qualifications. I genuinely do not accept that this has only happened since January 2005 and to tar those who have voluntarily put themselves up for training and assessment with the same brush as those who routinely carry out appalling work with no regard for the safety of their clients is just a lazy convenience for 'proper' electricians looking for someone to blame.
