Sharing account details as UK customer

I've just gotten the Virgin 360 box. I have a friend who is homeless (lives in a van at the moment), and I was wondering if I can share my app password with him so he can use Virgin on his phone and cast to his TV in the van? I know it would make a big difference for him but I am scared of my account being blocked. If it helps, he uses my address for important mail and is registered to vote etc here. He stays in my spare room when the weather gets too cold for his van but he doesn't live here and he is not family. His van is usually parked in the same place so I wonder if the location data would make it sus for Virgin. I also use the app on my phone and iPad.
