@4censord electrical engineering != professional electrician, these are different occupations
the former designs your laptop or USB charger or (in comparatively rare cases) grid distribution systems
the latter does the wiring in your house
You don't need to be qualified to work on a car's critical safety features, ie brakes, either. Just follow a youtube video then hurtle down the motorway at 70mph.
But, with electrics, you can't do work that needs certifying without jumping through hoops, getting it inspected by building control.
So new fuseboard, work in areas with extra risk, etc.
And any electrical work done by anyone needs to comply with BS7671:2018 and amendments, a 600+ page large book.
@russss this kinda works out as being regulated in practice though?
Building Control wouldn't sign off on pub rennovation work without an installation certificate from an electrician.
And for the warehouse the fire department required us to show them an EICR (IIRC it was a 5-yearly requirement).

i do know some hackspace and/or heritage railway people who have managed to do work such as adding a new circuit for an IEC 60309 socket, without being a formally-registered electrician ("catgirl/catenby who has studied the relevant regulations and knows how to do paperwork" was competent enough for their insurer)
also known some people in similar situations where the insurer wasn't as chill
