you got it.

no.
The other problem in the UK is there is no formal registry for a "builder" as opposed to plumbers, electricians and even window fitters that have to be registered.
There is definitely a need for good people skills (passive aggressive doesn't work on the building site) and being clear up-front. You also need to try and avoid over-reliance on one person/company, you don't want everything stopping because the electrician cancelled on you.
You don't even need good people skills, just being aggressive works, but you do have to be clear up-front: "stop right now, I am sure you fucked up this part: either prove to me I am wrong or redo it ASAP or I am not paying you for this" works much better than rolling out a list of complaints when they present the final bill.
In the UK, electricians do not have to be registered.
But I don’t know for sure.
Even that has been outlawed sadly. You can't fit your own fuse board and get an electrician to just sign off on it anymore - there might be people who still do it and give you a document saying they've done the installation, but in general it's not a thing anymore.
Of course absolutely nothing stops you from doing it anyway, then having a general electrical inspection done. If anyone asks just say it was like that when you bought the house already.
It is quite a racket in some towns, as some electricians will have an “expedited” relationship with the town’s inspectors, so you basically have to hire certain electricians if you want your project to move along smoothly. The electrician will come by and walk through for 5 min glancing here and there and sign the paper for $10k or $20k or $30k depending on size of the project.
Where I live, a homeowner is allowed to do their own electrical work. Must be permitted and inspected, though. When I've done big projects in the past, I've asked the inspector out at the start to ask for their advice -- gotten really good info that way.
There's a separate exam for solar installs. I took and passed that, but given that it is open book (you get the NEC book) and covers "only 3 sections of the NEC"), it was suprisingly hard.
That way, if an issue turned up later, he could prove by showing the pics that they forgot to do something or did it in the wrong way.
Contractors try to look after each other. Most know enough about other trades to stop and say "this isn't right, are you sure you want me to continue" if someone else did something wrong. But everyone once in a while this fails.
Of course they say that. What would you think if they said the opposite?
Not the same guy, but I might start to trust them more
Going every day is how you check the GCs work. A good GC should probably tell you the days where it's more important for you to come and check and what you should be looking for, but being there to notice things and ask questions helps keep things on track.
I remember when this became popular and also remember plenty of articles deriding the fact by architects and engineers both agreeing this was an incredibly poor idea for a number of reasons.
You'd be a thousand times better off just hiring an architect and doing a prefab or modular home.
I have a friend who plans on building a container house, and who is convinced that it will be much cheaper than a traditional house. Note that we live in Europe, where homes are build from stone and concrete, not wood and cardboard.
I've no idea what permissions you'd need for a container house.
EDIT: There's a caveat here. Because containers are trivially transportable, you have lots of options when it comes to assembling off-site that could be kind of nice. For instance, if you were a carpenter with a nice workshop, and wanted to fit out your house in your shop instead of in a muddy building site, it's kind of cool that you can do all the fitting, then put the parts on a truck. This would also be cheaper. If I was self-building, this would be a big consideration for me, because it's not actually very nice working in a building site, and it's not particularly efficient either.
As I recall, the biggest challenge was cutting out the sides while maintaining structural integrity. They ended up having to do a lot of complicated stuff to make it structurally sound, nearly negating the benefits of using containers in the first place.
But it looks great. I think the episode is on Netflix. Here [1] is an article with photos and a ten-minute clip from the episode.

I have heard many horror stories of people who had houses built and the builders made terrible mistakes. The person having the house built had to micromanage them and kept finding bad mistakes, like "forgetting" to put insulation in walls before the drywall, putting a window in the wrong spot, or putting crawlspace pillar supports in the wrong area.
I feel like right now the most reliable way to make sure my house gets built right is live nearby and check on it every day. Is there a better way?
