I thought the definition of a brothel was 2 or more WGs working from a single premises at the same time. Its why technically any girl offering a "MFF" with one of her WG friends is walking a dangerous line.
In this case you are only renting to a single WG. So i don't think that constitutes a brothel.
If you quoted (or read) my full post you would see the answer.
They don’t have to be working at the property at the same time, different days is classed as a brothel.
It’s not against the law for a single SP provider to work from a property.
However landlords have to be careful that they are not living off the earnings of prostitution (example of putting rent up was given but also could be taking an entrance fee per punter, or perhaps getting paid to change sheets, provide clean towels etc).
It is however a brothel if he rents it out to different SP or the SP let’s another SP use the room. Doesn’t matter if they work together doing duos etc or work on the same or different days.
I don’t think the law is that interested or doesn’t have the resources to follow up but reviewers are signposting when they make comments like “she uses the same flat as...” or I could hear a women in the room next door, or the maid/pimp let me in. If neighbours complain they could be investigated, prosecuted and premises boarded up.
OP can Work from a prison cell if his employer doesn’t sack him following the trial.
