There is no single law forcing a lock change between every tenancy, but a landlord has a duty to provide a secure home and to protect a tenant’s right to quiet enjoyment. In practice that means the outgoing tenant must not retain access, so changing the cylinders between tenancies is the safe, expected standard and protects you if anything goes wrong.
Short answer: There is no single law forcing a lock change between every tenancy, but a landlord has a duty to provide a secure home and to protect a tenant's right to quiet enjoyment. In practice that means the outgoing tenant must not retain access, so changing the cylinders between tenancies is the safe, expected standard and protects you if anything goes wrong.
Between tenancies, landlords often ask whether they are legally required to change the locks. The honest answer is that it is less about one specific rule and more about two duties that together make a lock change the sensible default. If you manage property in Stourbridge or the surrounding area and want a reliable locksmith to turn the job around between tenants, this guide covers exactly what is involved and what to watch out for.
The two duties that matter
- Providing a secure home.A landlord must let a property that is reasonably secure. If a previous tenant or their associates still hold working keys, that standard is hard to argue you have met.
- Quiet enjoyment.A new tenant has the right to occupy the home without others being able to enter. An old key in the wrong hands undermines exactly that.
You also cannot be sure how many keys the outgoing tenant cut over the course of the tenancy. As with a house move, the only way to guarantee the new tenant controls access is to change what the keys fit.
Why it protects you, not just the tenant
If a new tenant suffers a break-in or theft with no sign of forced entry, and the locks were never changed, you are in a very weak position. A documented lock change between tenancies is cheap insurance against that scenario and against a dispute over deposits or liability.
Treat a between-tenancy lock change the same way you treat a gas safety check: a routine, low-cost step that protects everyone and removes an argument before it can start.
What the job actually involves on the doorstep
Landlords sometimes picture a lock change as a lengthy job that eats into the void period. In most cases it is not. The vast majority of rental properties in Stourbridge and across the West Midlands have either a uPVC door with a Euro cylinder, a wooden door with a Yale-type nightlatch and a mortice deadlock, or a combination of both. Swapping a Euro cylinder takes a few minutes once you have the right replacement in hand. A nightlatch cylinder is similarly straightforward. A five-lever mortice deadlock takes a little longer because the lock body sits within the door, but it is still a contained task.
Where jobs take longer is when the existing hardware is worn or non-standard. I regularly arrive at rental properties and find cylinders that have been forced at some point and bodged back in, handles so loose the mechanism barely engages, or multipoint locking systems on uPVC doors where the gearbox is on its way out and would fail during the tenancy anyway. Catching those things between tenancies, rather than at midnight when a tenant is locked out, saves everyone significant hassle. If you find a uPVC door mechanism that needs attention, it is far better to address it during the void than to hand a new tenant a door that is already struggling.
What landlords get wrong when they skip the change
The most common mistake is assuming that because the outgoing tenant returned all the keys they were given, access is controlled. It is not. Keys can be cut at supermarket kiosks and hardware shops for a small amount. A tenant who had the property for two or three years had plenty of opportunity to have copies made, whether for convenience, for a family member or simply because they lost a key and had a spare cut rather than telling you. You have no way of knowing how many copies exist, and neither does the tenant if they are being straightforward with you.
The second mistake is changing the lock on the front door but overlooking secondary access points. Back doors, side gates with key-operated locks and outbuildings that connect to the main property all deserve the same attention. A thorough between-tenancy visit should cover every keyed entry point, not just the obvious one.
The third is leaving it until the new tenant has already moved in. At that point you need to arrange access around their schedule, and if anything feels uncomfortable about the situation for the new tenant, that is not a good start to the relationship. The change should happen after the outgoing tenant has left and before the new one takes possession.
How to tell one situation from another
Not every tenancy change is the same, and it is worth thinking about the level of risk in each case before deciding on approach.
- Routine end of tenancy, no disputes.A standard cylinder swap is sufficient. The outgoing tenant had no reason to be awkward, the relationship ended normally, and you are simply applying good practice.
- Tenancy ended in dispute or acrimony.This warrants a closer look at the whole property, not just the cylinders. Consider whether the existing lock grade is adequate and whether an upgrade to a higher-security cylinder makes sense while you are at it. A snap-resistant cylinder costs little more than a standard replacement and adds meaningful protection. See our anti-snap lock upgrade service for detail on what that involves.
- Property has been vacant for a longer period.If the property has sat empty for some time, check the overall condition of the hardware rather than assuming it is fine because nobody has been there. Cylinders can corrode, uPVC mechanisms can seize, and a lock that is stiff or difficult to operate is not one you want a new tenant relying on.
- Tenant abandoned the property.In any situation where a tenancy ended without a clean handover, treat access as unknown and change everything that matters.
Doing it efficiently across a portfolio
For landlords and agents with several properties, a few practical tips:
- Change cylinders, not whole locks,to keep cost and time down between tenancies.
- Keep a recordof the date and property, so you can evidence it if ever questioned.
- Consider keyed-alike sets per propertyso each home has one simple key, while keeping different properties on different keys.
- Build a relationship with one local locksmithwho can turn jobs around quickly between tenancies rather than calling a stranger each time.

FAQ
Are landlords legally required to change locks between tenancies?
There is no single law mandating it for every tenancy, but landlords must provide a secure home and protect the new tenant's quiet enjoyment. Changing the cylinders is the practical way to meet both duties and limit your liability.
Can I just change the cylinders rather than whole locks?
Yes, and for most doors that is the efficient choice. Swapping the cylinder makes every previous key useless without the cost of replacing entire lock assemblies. On a uPVC door the cylinder is usually the only part that needs changing unless the mechanism itself has a fault.
What if the outgoing tenant handed all keys back - is a lock change still necessary?
Yes. You have no reliable way of knowing whether copies were made during the tenancy. Returned keys only account for the ones you issued. A cylinder change is the only way to be certain that every key cut from the previous tenancy, whether you know about it or not, no longer works.
Do you cover Stourbridge for between-tenancy lock changes?
Yes. We carry out between-tenancy lock changes for landlords and letting agents across the West Midlands including Stourbridge. We can usually attend promptly to keep void periods short.
Should I upgrade the lock at the same time as changing it?
It depends on what is already fitted. If the property has a standard cylinder with no snap resistance, a between-tenancy change is a sensible moment to fit a higher-security replacement at minimal extra effort. If the hardware is already of a good standard and in good condition, a like-for-like cylinder swap is fine. A locksmith visiting the property can give you a straightforward view on what is there and whether it is adequate.
