I would never let an unknown person in to my house on his own; I
cannot imagine that any sensible person would do so either.

Are your electricity and gas meters outside?

Metermen (without a court order) do not let themselves into your home
when you are out. Or do you know some the rest of us do not? :-)

Judith said "letting an unknown person in", not "letting an unknown
person let themselves in".

Yes, I can see you might read it that way without the context of the
thread topic but by "on their own" she means with her not there.

Fair enough. I read the "on his own" as meaning "just one person, and
not with a second one to act as a witness".
