Can a landlord require tenants to use a burglar alarm?

A landlord's ability to require alarm use comes from the contract, not from a statute. Whether a clause binds the tenant depends on it being reasonable and clearly agreed.

Where the requirement comes from

There is no law that forces a tenant to use a burglar alarm. Any obligation arises from the tenancy agreement. A landlord who wants tenants to set and use an alarm should include a clear, specific term to that effect — for example, requiring the alarm to be set when the property is left unoccupied. Without such a clause, the landlord has little contractual basis to insist.

The most common reason a landlord includes this term is the landlord's own insurance condition. If the buildings or contents policy requires the alarm to be set and maintained for theft cover to apply, the landlord needs the tenant to actually use it. Writing the requirement into the tenancy aligns the tenant's behaviour with the insurer's condition, protecting both parties from a refused theft claim.

What makes the clause enforceable

A tenancy term about alarm use is enforceable if it is reasonable, clearly expressed and properly part of the agreement. Several factors matter:

• the clause should be specific — what the tenant must do (set the alarm when out), not a vague aspiration;
• it must be practical — the tenant must have a working alarm, the codes, and instructions on how to use it;
• it should not unfairly penalise the tenant for matters outside their control, such as a system fault;
• it must respect the tenant's right to quiet enjoyment and not impose disproportionate conditions on ordinary living.

Consumer protection rules on fairness in contracts apply to tenancy terms, so an unreasonable or one-sided clause may not be enforceable. A balanced clause — tenant sets the alarm, landlord keeps it maintained — is far more likely to stand than one that, say, makes the tenant liable for any theft simply because an alarm was involved.

Typical split of alarm responsibilities in a tenancy. The actual division depends on the agreement; confirm in writing.

Maintenance, faults and fairness

Because the alarm is part of the let property, the landlord normally retains responsibility for its maintenance and repair, just as with other fixtures. A tenant can reasonably be asked to set and use the alarm and to report faults promptly, but should not be expected to arrange servicing or be blamed for a fault they did not cause and could not fix. If the alarm breaks, the sensible expectation is that the tenant reports it and the landlord repairs it.

This division also protects the insurance position. The landlord keeps the system maintained (often a policy condition), and the tenant uses it as required. Problems usually arise only when this is unclear — the tenant does not know the codes, the alarm faults and no one fixes it, or the agreement is silent on who does what. A well-drafted clause plus clear handover of codes and instructions avoids most disputes.

Practical advice for both sides

For landlords, the route to requiring alarm use is a clear, fair tenancy clause, backed by a working system, handed-over codes and instructions, and continued maintenance of the alarm. Where the requirement stems from an insurance condition, it helps to explain that to the tenant, so they understand why setting the alarm matters. Keep the maintenance and any service records, as these protect a future theft claim.

For tenants, the key is to read the tenancy and understand any alarm obligation: what you must do, when, and who fixes faults. If a clause looks impractical or unfair — for instance, it makes you responsible for servicing or penalises you for faults — raise it before signing, or seek advice from a service such as Shelter or Citizens Advice. Because tenancy law and contract-fairness rules differ across the UK nations and individual agreements vary, both parties should confirm their position against the specific tenancy and current guidance rather than rely on a general summary.

One scenario deserves particular care: a tenant who wants to fit their own alarm in a property that has none. Because installing a wired system or fixing a bell box to the external wall is an alteration to the landlord's property, the tenancy usually requires the landlord's written consent first, and the tenant may be expected to make good on leaving. A wireless or plug-in system that leaves no permanent marks is less likely to need consent, but checking the tenancy term on alterations avoids a dispute over the deposit later. From the landlord's side, agreeing to a tenant's reasonable request can improve security at no cost, provided responsibility for the equipment, its removal and any redecoration is set out clearly in writing at the time the consent is given.
