Not too worried about these so much, as the cabling is still exposed and can be visually inspected. Nothing is connected at present. Its very much 1st fix cabling stage.

Why not? You can certify that they were designed and constructed properly, you can carry out continuity tests,IR tests...
Yes, it is. That quote of mine you've produced is over two years old but, although the regulation numbers have changed since then, they still say the same thing.
In theory. However, in practice, one would have to find a way of 'proving' that the 'safe functioning' of the lighting equipment was not impaired by the voltage drop in question, and that might not be straightforward. In that context, 'safe functioning' probably goes beyond electrical safety, since impaired lighting can lead to secondary dangers.
As was discussed in that old thread, if one has a very long feed to an outhouse (it was 350m in that case), it is well worth considering alternative lighting strategies (e.g. ELV lighting with a very supply-voltage-tolerant power supply - or even a battery and charger), so as to avoid the 3% VD limit. However, as we've established, this isn't really an issue in the current thread, given that there is only ~40m of 25mm² cable.

You could, but what you'd end up would not be a fully-completed EIC, or Schedule.
The only really issue is any concealed (hence uninspectable cable), and my understanding is that, in the OP's case, that only applies to the underground feed to the outhouse. In all other cases, there is no sensible reason why a 'new electrician' cannot undertake and 'sign for' all the testing, and also 'sign for' all the design & construction, just as if they had literally done it themselves.

You're not being naive, but you're talking about very sophisticated and expensive equipment (as you imply, probably using RF) that no ordinary electrician would have - and, I would have suspected, no certainty of detecting joins (particularly if they were 'very good'). Then you would need 'ground penetrating radar' or somesuch to confirm that the cable was at a satisfactory depth throughout its length.
However, as I've said, I think that when you start talking to real-world electricians, you will probably find that there is, in practice, far less of an issue than BAS is suggesting.

I was more talking about the fact that the OP seems to have installed a CU and a bunch of final circuits, and is wanting an electrician to come along, connect, test, and say he did the lot.
I realise that. However, as I've just said, even if that were the case (but see below), I really don't see a problem. If, as we've been told, all the cabling is visible and inspectable, the new electrician can effectively approve the design and construction of 'the lot', and test 'the lot' - just as would have been the case if, say, the work had been undertaken by an apprentice under his/her supervision. I would certainly not see any deviation from the spirit, and probably not even the word, of the certification process if this were the case.
However, recent posts from the OP suggest that it may not even be true that "a CU and a bunch of final circuits have been installed". It now sounds to me as if the situation may well even be that a CU and backboxes have been screwed to walls, and (visible) cables run between them, but with nothing yet actually 'connected' (i.e. a classic 'first fix').
As I said, it sounds as if the only real possible issue relates to the underground cable, and I suspect that even a (sensible) BCO would not get too excited about that. By analogy, if a house had an old, now unused (disconnected at both ends) cable which used to feed, say, a cooker or shower, I would think that (provided the cable tested OK) electricians would usually be happy to install a new circuit using that cable, without digging it all out to satisfy themselves about its routing.
Kind Regards, John
BAS. You are jumping to conclusions. The wiring has been carried out, to the CU in the out house, but nothing is connected. I am in first fix stage.
Plasterboard is not going on until next week, which is why I am looking for an electrician now, to complete this element, so that in November they can come back and connect up to the main feed when the energy supplier turns up to turn the power off.
Where does it say that the consumer unit is populated?
