The short answer
No. There is no law requiring a burglar (intruder) alarm in a rented home or a house in multiple occupation (HMO). It is important not to confuse intruder alarms with fire and smoke alarms, which are a different matter: landlords in England must provide working smoke alarms on each storey and carbon monoxide alarms where there is a fixed combustion appliance, and HMOs face stricter fire safety requirements, often including interlinked fire detection. A burglar alarm, by contrast, is generally optional — driven by the landlord's choice, the tenancy agreement or an insurance condition rather than statute. So the mandatory alarms in rentals are about fire and CO, while intruder alarms remain a security and insurance decision.
The word 'alarm' causes confusion in rented property. Fire and carbon monoxide alarms are tightly regulated; intruder alarms are not legally required at all.

Intruder alarms are not legally mandatory
Across the UK there is no statutory requirement for a landlord to fit a burglar alarm in a rented property or an HMO. Security against intruders is treated as a matter of good locks, sensible measures and individual choice rather than a legal obligation backed by a specific alarm law. A landlord can choose to install one, and a tenancy agreement can address its use, but the law does not compel it.
This is different from the duty to keep a property reasonably secure and in good repair. A landlord is generally expected to provide a property with working external doors and windows and adequate locks, and to maintain the structure. An intruder alarm sits above that baseline as an optional enhancement, not a mandatory fixture.
The alarms that ARE required: fire and carbon monoxide
The confusion usually arises because fire and carbon monoxide alarms genuinely are regulated, and the rules are stricter still in HMOs. In England, landlords must:
- provide a working smoke alarm on every storey of the property used as living accommodation;
- provide a carbon monoxide alarm in any room with a fixed combustion appliance (such as a gas boiler or solid-fuel fire);
- ensure the alarms are working at the start of each new tenancy, with tenants generally responsible for testing during the tenancy.
HMOs carry enhanced fire safety obligations because more households share the building. These commonly include a more comprehensive, often interlinked fire detection system, fire doors and clear escape routes, and may be conditions of an HMO licence. None of this concerns intruder alarms — it is about getting people out safely in a fire — but it is the source of the idea that 'alarms are required' in rentals.
| Alarm / measure | Legally required in rentals? |
|---|---|
| Smoke alarms (per storey, England) | Yes |
| Carbon monoxide alarms (combustion appliance) | Yes |
| HMO interlinked fire detection | Often, via fire safety / licence |
| Burglar / intruder alarm | No |
| Adequate door and window locks | Expected (repair / security duty) |

When a burglar alarm still comes into play
Although not legally required, an intruder alarm can become relevant in a rental for other reasons. A landlord's insurance policy may attach an alarm condition — for a higher-value, higher-risk or HMO property — in which case the landlord must meet that condition to keep the theft cover valid, even though no statute demands the alarm. The tenancy agreement may also deal with an existing alarm: who sets and maintains it, and who holds the codes.
For HMOs in particular, a landlord may choose an alarm as part of a wider security approach, especially where multiple tenants come and go. But this remains a commercial and contractual decision, not a legal mandate. A tenant cannot be prosecuted for the absence of a burglar alarm, and a landlord does not breach housing law simply by not providing one — the legal exposure around alarms in rentals is firmly on the fire and CO side.
What landlords and tenants should check
For landlords, the priorities set by law are clear: install and check the required smoke and CO alarms, meet any HMO fire safety and licensing conditions, and keep the property secure and in repair. Any burglar alarm is then an additional choice, and if the landlord's insurer makes one a condition, the landlord should ensure it is maintained and the conditions met. The tenancy agreement should set out responsibilities for any alarm provided.
For tenants, the right questions are about the safety alarms that must be present and working, and about who is responsible for any burglar alarm in the property — setting it, maintaining it, and what happens if it faults. Because the detailed rules differ across the UK nations and HMO requirements can be set locally, both landlords and tenants should confirm the current position with the relevant local authority or housing guidance rather than rely on a general summary, particularly for HMO licensing and fire safety.
It is also worth being clear about contents insurance in a rental, because that is where an intruder alarm most often becomes relevant for a tenant. A landlord's policy typically covers the building and the landlord's own contents, not the tenant's possessions; a tenant who wants their belongings protected against theft usually needs their own contents policy. If that tenant's insurer attaches an alarm condition — uncommon for an ordinary flat, but possible for high-value belongings — the tenant would then need a working alarm and the landlord's agreement to use it. So while no law compels an alarm in a rental, the practical case for one can come from a tenant's own contents cover just as much as from the landlord's policy.
Frequently asked questions
Is a burglar alarm required by law in a rented home?
No. No UK law requires an intruder alarm in a rented property or HMO. Security is a matter of adequate locks and choice. The alarms that are legally required are smoke and carbon monoxide alarms, and HMO fire detection.
What alarms must a landlord provide?
In England, a working smoke alarm on each storey and a carbon monoxide alarm in any room with a fixed combustion appliance, working at the start of each tenancy. HMOs usually need enhanced, often interlinked fire detection under fire safety rules or licensing.
Why might an HMO still have a burglar alarm?
Usually because the landlord chooses one for security, or an insurer makes it a condition of cover for a higher-risk property. It remains optional and contractual, not a legal requirement, and the tenancy should set out who maintains it.
