What Happens If I Don't Leave After a Section 21 Notice?
Direct answer
A tenant usually does not have to leave immediately after a Section 21 notice. The landlord normally needs a court order and bailiffs before lawful eviction.
A Section 21 notice is not the eviction itself. It is a formal step that says the landlord wants possession after a stated date.
If the notice expires and the tenant stays, the tenancy does not automatically end. The landlord must decide whether to start a possession claim at the county court.
If the court grants possession and the tenant still does not leave, the landlord must apply for enforcement. A landlord should not personally change locks or remove belongings to force the tenant out.

Common questions
- Do I have to leave after a Section 21 notice?
- Usually, no. A Section 21 notice is not the eviction itself. The landlord normally needs a county court possession order and, if you still do not leave, bailiff enforcement before you can be lawfully removed.
- Can landlord evict me without court?
- No. A landlord cannot lawfully evict a residential occupier by changing locks, removing belongings, cutting off services, or forcing them out without the proper court process. That can be unlawful eviction or harassment.
- What happens if I stay?
- If you stay after the notice expires, the landlord must decide whether to start a possession claim. You should keep paying rent, keep all papers, check whether the notice is valid, and respond quickly if court papers arrive.
- Can landlord change locks?
- No. A landlord should not change the locks to force you out while you are still entitled to occupy. If locks are changed or you are threatened, seek urgent housing advice and contact the council or police if there is immediate risk.
