DETAILED ANSWER · HOME SECURITY AND STANDARDS
How can renters ask about lock security responsibly?
Read security advice and understand what product standards do and do not mean.
Check your tenancy agreement and speak with your landlord or managing agent before changing a lock when it is safe to do so. Shelter England notes that a tenant who feels unsafe may be able to change a lock, while advising them to keep the original lock to put back at the end of the tenancy. Circumstances and agreements differ, particularly in shared housing.
If you are unsure or feel at risk, get housing advice before acting.
