3 things;
1 some people wish to attempt jobs that no diy person should
I maintain that within the context of a domestic installation, there are no jobs that are
per se ones that a DIY-er should not do. Yes there are some that require more knowledge than many DIY-ers have, and there are some DIY-ers who are so clueless that they'd never be able to acquire the knowledge and skills needed, in the same way that I expect some people drop out of 2360 courses because they can't hack it. But I can't think of any domestic stuff that is necessarily outside the scope of any DIY-er.
2 some people should not do any diy
You're not wrong there.
3 some people take on jobs above their ability
Or there. And what're worse are the people who, having asked, won't accept being advised that a particular job is above their ability.

Point 1. DIY is a noble hobby and most DIYers take pleasure from learning how to undertake a particular task and then completing it in a methodical way with skill and attention to detail that would outclass any professional job.
Undeniably true - looking beyond electrics for example, if you think about the time it takes to
properly prepare an old painted surface for repainting, particularly if it has awkward contours, like windows, to pay someone a going rate to do that would make it ruinously expensive. I DIY for a number of reasons; interest, satisfaction, convenience, cost and yes, in some cases, quality of results.
Point 2. Unfortunately, there are those that see DIY as a way to save money. Often they don't want to purchase expensive equipment, don't want to do a job the proper way or don't want to take time to understand the details of the task - they simply want to complete the task as quickly and cheaply as possible, even if that means dangerous, potentially dangerous or sub-standard work. Perhaps these people don't deserve the title DIYer or perhaps they give the hobby a bad name. Either way, to these people we all have a responsibility to point out the error of their ways - the Electricans on this board more than most. To urge caution, to attempt to educate, to refer them to the appropriate literature and to hope they take our advice. I agree that sometimes advice can be perceived as discouragement but I don't believe this is intentional.
I agree entirely. As I said above, I don't think that there are any jobs that are flat-out unsuitable for DIY-ing, but as a DIY-er myself I know full well that there are many jobs that require more knowledge than some of the posters patently have. It is difficult sometimes to get across the point that yes, you can rewire your house, but you can't do it this weekend, or even next month, or possibly even this year, because of all of the things that you don't yet know, and more importantly, all of the things that you don't even
realise you don't know. It often comes appears condescending, and I admit that I sometimes (often?

) don't try hard enough to stress that I'm not being condescending.
Point 3. Similarly, most DIYers either already have all the knowledge, skills and tools required to add a socket to a ring final - or could be taught with ease. However, it is my firm belief that there are a minority of DIYers who will never meet any particular competency level and certainly not with the limited communication possible in a forum such as this. What is within ability for one individual may not be for another.
I'm sure that a lot of the horror stories of bodged DIY work arise not because the perpetrator didn't care, or was intrinsically incompetent, but simply because they just didn't know that you shouldn't put all those sockets on a spur, or borrow a neutral for a light or whatever. In many ways the clueless who come here end up safer then the class of person you mention - someone who already has the knowledge, skills and tools required to add a socket to a ring final, and thinks that therefore they have the knowledge, skills and tools required to rewire a house, run a cable out to their shed and install a new CU.

How does one make a judgement as to what a DIYer is capable of?
The $64,000 question. It isn't easy, and I, and I'm sure the others, get it wrong both ways sometimes.
Some words in a post? A lack of knowledge or poor english does not necessarily imply a lack of capability - if posters had the knowlege, they wouldn't post. To critisize harshly on this basis is uncalled for.
I don't always succeed, but I do try not to criticise people on the basis of the words they use, however I think it is reasonable to take the gross misuse of technical terms as a good indication of people's knowledge. Not their
potential ability, but where they are right now. For example people who worry that a 3kW oven on a 40A circuit might somehow be damaged by being given too much electricity. In the recent brouhaha with Roman, it was obvious that English was not his native tongue (but he's far better at it than I am at any foreign language) - what got me going was his refusal to accept that there were things he needed to learn, and that you could not rewire a house on the basis of "insert knob A into hole B" type instructions.
However I think it is fine to advise that xyz job is best left to a pro.
Which jobs, and how and when do
you think that should be the advice?
In my profession we also have to be aware of the possibilities of litigation, harm, consequential loss etc. steming from advice and all documents have a disclaimer.
It'll be interesting to see what happens next year...

Surely electric work requires a lot of knowledge but the ability to strip the insulation and secure a wire is easily learned. The important bit is what size wire and where it should go etc.
There are other very important things. What do you about a DIY-er who can strip wires, and even knows that the capacity of 6mm² cable is 47A, but has never heard of installation methods, voltage drop, grouping factors etc, and thinks that therefore it must always be OK for a 10.5kW shower. Or who has never heard of TT, TN-S etc, and therefore has absolutely no idea how that affects a choice of CU.
I think diy electricians may actually take more care because they are not doing it 40 hours per week. They know their work will come under greater scrutiny because they are not real sparkies.
Those who care will care. Those who know that their work will never be scrutinised, as there is no framework for doing so, will carry on in blissful ignorance of all their mistakes.
I've always thought that the government missed a trick with Part P. I really do believe that the vast majority of poor DIY electrical work arises out of well-meaning ignorance, and this state will hardly, if at all, be remedied by telling people that they are no longer allowed to do it. It is fascinating to see the emergence of some fairly short training courses aimed at getting kitchen fitters and pl**bers up to spec for domestic installation work, and there was, and still is, no reason why this scheme could not be extended to householders. Indeed, if it wasn't for the fact that NICEIC would require me to offer a guarantee to myself, and to have liability insurance for risks to myself, and to buy all the bl**dy books again from them, I'd seriously consider it.

I've just recently posted a question about isolating my CU unit and it turns out that the earthing is suspect and as a result I've decided to call in a professional. While one of the posts in my thread was one of discouragement it turned out to be correct I think, but I believe if someone actively discourages someone asking for advice they should also tell them why a professional should be called out rather than just stating it as a fact.
True.
My thread is a case in point because the experts who contributed were very polite and effectively pushed me to the right conclusion with their recommendations. Having said that, I believe a DIYer can, with care and attention, work to a high standard.
I'd have to agree with that, wouldn't I!
However, perhaps it is best to leave the safety critical sections to the professionals such as, coincidentally, earthing at the meter and fitting isolation units to the incoming mains, plus with the professional there, I get to extract as much info about how to do the rest of the work myself
Smart move. You probably could have done it all yourself, but given the state it was in, I think you were wise to go for the faster option of getting in a pro. Was he happy to give you advice on other matters, or was it like pulling teeth?
