Her rental contract should state specifically that they require no rights and it’s important that there is rent paid.
If your friend is living in the property, even better. It becomes problematical, provided she lives in the property and provided some facilities are shared such as a bathroom et cetera, then the person is no more than a lodger and if rent is paid weekly, then your friend only needs to give one week’s notice and if the person doesn’t leave she can actually unlock them out provided she gives them their belongings back.
When you say a lodger, I assume that you live in the same property. If that’s the case, then you need to give him one month notice which does not necessarily have to be in writing but it’s better if it is.
Provided he shares some facilities, kitchen, bathroom, lounge, whatever, and his accommodation is not self-contained, then you do not need a court order to get him out and when the notice has expired, you can simply lock him out provided you give him his belongings back.
Here it is from the government website.
It can be more problematical if she doesn’t live in the property and they don’t move out. It does happen.
