Smoke and Carbon Monoxide Alarms: NI Landlord Duties

Living in a rented home means relying on your landlord to make sure basic safety measures are in place. In Northern Ireland, tenants should know what landlords are expected to install and maintain when it comes to smoke and carbon monoxide alarms, how to check that devices are working, and what to do if alarms are missing or faulty. This guide explains the landlord duties under current law, gives practical examples of when to report problems, shows how to use official forms and where to apply to the tribunal if needed, and outlines simple steps tenants can take to stay safe while seeking a resolution.

What landlords must do

Under the Private Tenancies Act (Northern Ireland) 2022 landlords have duties to keep rented homes safe and in repair. Landlords should follow local fire safety guidance on smoke and carbon monoxide alarms and act promptly when tenants report faults.[1][2]

  • Install and maintain working smoke alarms on every storey of the rented property.
  • Provide a carbon monoxide alarm where there is a fixed solid-fuel burning appliance or other relevant device.
  • Repair or replace faulty alarms promptly after a tenant reports the issue.
  • Keep written records of safety checks, alarm tests, and any repairs carried out.
  • Respond to tenant reports within a reasonable time and provide clear timescales for inspection or repair.
Keep a dated photo of any faulty alarm when you report it.

When landlords must act and examples

If an alarm is missing on a floor used regularly by tenants, ask the landlord in writing to replace it. If a carbon monoxide alarm sounds or reports a fault, the landlord should arrange inspection and repair without delay. If the landlord does not act, tenants can follow formal complaint steps and, if necessary, make an application to the relevant tribunal for Northern Ireland.[3]

Official forms and when to use them

There are a few official actions tenants and landlords may use:

  • Notice to Quit / written notice: used by a landlord or tenant to formally notify an intention to end a tenancy; tenants sometimes use written notice to record requests for repairs in line with tenancy terms.
  • Application to the Residential Property Tribunal: use this when a landlord fails to make required safety repairs and informal complaints have not resolved the issue; the tribunal can order repairs or other remedies.[3]
  • Formal disrepair report: submit a clear written report with dates, photos and any correspondence to request prompt action; keep copies for your records.

Practical example: if a carbon monoxide alarm is missing and your landlord does not respond within seven days of a written report, send a dated written reminder, keep a copy, and consider applying to the tribunal if there is still no action.
