A Landlord's Guide to Lock Changes Between Tenancies
Changing the locks between tenants is one of the simplest ways to protect a property — and often expected by insurers. Here's the practical guide.
Why change locks between tenancies
When a tenant leaves, you can't be sure how many keys exist or who has copies — old tenants, their friends, contractors, or previous letting agents. Changing the locks gives the new tenant (and you) a secure, clean start.
It also protects you: if a property is entered with a copied key, your insurance and liability position is much weaker if the locks were never changed.
You usually only need the cylinders
On UPVC and composite doors, swapping the euro cylinders is quick and cost-effective — you don't need to replace whole mechanisms. On timber doors, the mortice lock can be replaced or re-keyed. A locksmith can do a whole property in a single visit.
It's also a good moment to upgrade to anti-snap, British Standard cylinders so the property meets insurance requirements.
Make it part of your turnover routine
Building a lock change into every tenancy turnover is inexpensive peace of mind, and tenants increasingly expect it. Keep the invoice for your records — it demonstrates a duty of care.

Every visit is handled with a security-first approach. We check the door, frame, keep, cylinder, handle, closer or mechanism before recommending a repair, so customers understand whether the fault is a simple adjustment, a lock replacement, a UPVC gearbox failure, a commercial door alignment issue or urgent make-safe work after damage.
