You're right, outcalls are probably safer what with all the checks. When I do incalls I get some guys booking one week under one name, and the next week under something completely different! (Don't think it's anything sinister, think they're just doing it for their anonymity- but it sure as hell confuses me!!!)
You could try getting someone to work with you, especcailly if you have 2 bedrooms (although I think unfortunately that's still illegal, even if you are not with a client at the same time, or even the same day- it's a shame because legalising 2 or 3 girls working together would be so much safer. It's up to you whether you take that chance, but lots of people have flatmates and if you're discreet no one is likely to notice, but there would be double the 'traffic' to your door!)
You could try getting a friend or hired help to sit in with you, which is legal i think as long as they're not controlling you or working themselves (I sometimes pay a guy a cut of the booking to sit in with me) - obviously not in the same room :)I find it best if the client doesn't know there's another man there though- it makes them nervous and ruins the 'Girlfriend-experience' . Some people may disagree though. Clients are usually ok at outcalls when they know your driver is parked only one street away.
You could always perform the same landline number/ID checks we do for outcalls. I've never heard of these being done for incalls though, but maybe someone else has?
Sorry I can't be of that much help, and I'm not a lawyer, so I'd double check the legal stuff (it's correct to the best of my knowledge though)
Also, I tell the clients to call me when they get to a familiar landmark 5 mins from my incall flat, and only then do i tell them the full address. I make sure I tell them on the phone, NOT in a text message, because they are less likely to remember a conversation whilst possibly nervous, but they could read an old text message on a drunken night out and think it's a good idea to show up at the door
Don't let the neighbours know about your private details (eg name, 'real' job or place of study). Use your escort name and a believable work-from-home job (think this is on another thread) in case they say hello in front of clients or if you are found out and have to move to another lease.
Good Luck x
