When Landlords Must Replace Smoke Alarms in Scotland

Health, Safety & Fire Regulations Scotland 3 min read · published March 09, 2026 Flag of Scotland

Tenants often rely on landlords to provide working alarms that protect lives and property. In Scotland, landlords have specific legal duties to install and maintain smoke, heat and carbon monoxide alarms so homes meet basic safety standards. This guide explains when a landlord must replace an alarm, who pays, what to do if alarms fail, and practical steps tenants can take to report problems or seek enforcement. It uses plain language for renters and shows the official routes — including local authority reporting and applying to the First-tier Tribunal — so you can act confidently if an alarm is missing, non-functional, or past its recommended life. Keep clear records and follow the steps here to protect your safety.

What landlords must provide

Landlords in Scotland must ensure at least one working smoke alarm on each storey, keep alarms in working order and provide a carbon monoxide alarm where there is a fixed combustion appliance. Official guidance and the relevant housing law set out these duties and practical expectations for landlords and tenants.[1][2]

Keep a dated photo of any non-working alarm and the message you sent your landlord.

When replacement is required

Typical situations when a landlord must repair or replace an alarm include:

  • Non-working alarms that cannot be fixed by a simple battery change should be repaired or replaced promptly.
  • Missing alarms where a required device was never installed must be provided by the landlord.
  • Alarms that are visibly damaged or past the manufacturerxpected life should be replaced to meet safety standards.
Do not tamper with alarms; altering devices can create a safety risk and affect legal remedies.

Official forms and routes

If a landlord does not replace or repair life-safety alarms, tenants can use official enforcement routes.

  • Online application to the First-tier Tribunal for Scotland (Housing and Property Chamber): use the tribunalmake-an-application pages to submit an application seeking enforcement or an order when a landlord fails to act. Attach photos, written requests to the landlord, and any inspection reports.[3]
  • Report to your local authority(housing standards or environmental health): councils can inspect and require landlords to fix or replace alarms that breach safety standards; use your councilonline reporting form or phone line to start this process.
Early, written notice and clear evidence increases the chance of a fast resolution.

FAQ

When must a landlord replace a smoke, heat or carbon monoxide alarm?
Landlords must provide working alarms in the required locations and replace or repair faulty devices so homes meet safety standards; check official guidance and the Private Housing (Tenancies) (Scotland) Act for details.[1][2]
What if my landlord does not replace a faulty alarm?
If your landlord does not act after you report the problem in writing, you can report the hazard to your local authority and, if needed, apply to the First-tier Tribunal (Housing and Property Chamber) for an enforcement remedy. Keep copies of all communication and evidence.[3]
Can I replace an alarm myself and deduct the cost from my rent?
You should not unilaterally deduct costs from rent. Ask the landlord in writing for permission; if they refuse or ignore you, use the council reporting route or the tribunal to seek repayment or an order rather than deducting rent yourself.

How-To

  1. Tell your landlord in writing: explain the fault, request a repair or replacement, state a clear deadline, and keep a copy of the message as evidence.
  2. Keep records and evidence: keep dated photos, messages, receipts and any inspection notes to show the problem and your attempts to resolve it.
  3. Report to the local authority if the landlord does not act: use your councilhousing standards or environmental health reporting process so the authority can inspect and order repairs.
  4. Apply to the First-tier Tribunal (Housing and Property Chamber) if enforcement is still needed: submit the tribunal application with evidence and follow guidance on the tribunal website for supporting documents.
