I did look on the UK .gov site when I first saw this thread, iirc when
you get into the real info self employed are not required to have the
same safety equipment as an employer would.
The front page I saw was mostly planning and rates and blanked health
and safety, says me hiding from .gov types in the UK too :)
Hence my collection site only mentions donations and even if I get
asked up front before I scan something I just say donation, and just
do the scan, provide the url, and hope for the best.
Doing the occasional job for a few notes is also within planning I
believe if its not the main job and also not more than x times a year,
I remember reading something about the frequency test of amateur car
car sales in that regard.
Also working from hope planning has been relaxed a bit for teleworking
etc. but the official line often shows the onerous catch all wording.
