"You are likely to be an excluded occupier if you share living accommodation with your landlord. If you are an excluded occupier your landlord can evict you without having to go to court. This section explains how landlords can evict excluded occupiers."
If you have a written agreement with your landlord it may state how much notice the landlord has to give you. If that is the case then this is the minimum notice required. If you have lived in your home for a long time it may be possible to argue that it would be reasonable to give a longer period of notice.
If you don't have a written agreement with the landlord you may still have agreed with your landlord about the length of notice before you leave. If not the landlord has to give reasonable notice.
There are no set rules about what is reasonable. It depends on:
the length of time you have been living there
the length of time between rent payments
whether you have been getting on with your landlord
how quickly the landlord needs someone else to move in.
