Notes

  • Applies to England only and to landlords of specified tenancies. It is not read here as a rule for owner-occupied homes. Wales and Northern Ireland are not covered.
  • The landlord must check each alarm works on the day a new tenancy starts, and repair or replace an alarm found faulty after a tenant's report, as soon as reasonably practicable. Carbon monoxide alarms are also required in rooms with a fixed combustion appliance other than a gas cooker.
  • Smoke alarms in the private rented sector since 1 October 2015. Carbon monoxide alarms in the private rented sector, and smoke and carbon monoxide alarms in the social rented sector, since 1 October 2022.
  • Scottish Government factsheet. A carbon monoxide detector is also required in the same room as any carbon-fuelled appliance.
  • The factsheet consulted does not say who must keep the alarms working, and does not mention rented homes.
  • The factsheet records an update on 15 February 2022 on timescales but the date for compliance was not stated on the page read.
