My landlord/housemates say I can’t live in my house as I need to self isolate.

If you have a contract and are paying rent, your landlord or housemates can’t tell you that you are not allowed to live in the property. You can self-isolate within the house, maybe ask your housemates to prepare food for you that you can take into your room. If you have any concerns about how you are being treated or demands from your landlord please get in touch with LUU Advice.
