Running commercial concern in a domestic dwelling.

Very hard to prove, because I'm not.

In actual fact, all sorts of working from home is perfectly legal - and
indeed actively encouraged - so called tele-working for instance or IT
jobs. Very large varieties of work could be conducted at home and the list
is growing. Government and local authorities encourage this for all sorts
of sound reasons - from being better for "the family", for carers, for
disabled people for parents of the very young, for part timers - as well as
being often much more socially, ecologically and environmentally sound.

It's not that long ago historically when everyone effectively worked at
home or from home.

In general (aside from restrictive covenants and ground leases etc) the
only problems you are likely to face working from home as far as government
and the law are concerend is where you will have major noise or traffic or
other impact on your neighbours: Things like running a large commercial car
repair shop in the street, 24 hour light engineering, a knocking shop or a
retailers. But "quiet" or "indoors" type work with no local traffic impact
is all perfectly legal.

There is of course CGT to consider, but that's another matter.
