Do landlords have to provide carbon monoxide alarms?
By the VoxaMTD team. Last verified 31 October 2026
Yes, in England. Since 1 October 2022 a landlord must equip any room used as living accommodation that contains a fixed combustion appliance, other than a gas cooker, with a carbon monoxide alarm. A smoke alarm is also needed on every storey that has a room used as living accommodation.
Before 1 October 2022 the carbon monoxide duty covered only rooms with a solid fuel burning appliance. The amended regulations replaced that wording with fixed combustion appliance, which is broader. Check each room that has a fixed appliance, such as a boiler, a gas fire or a wood burner, and fit an alarm where the rule applies.
Alarms must be kept working. Where a tenant or their nominated representative reports that an alarm is not in proper working order, the regulations require the landlord to repair or replace it, and to determine and fix the fault as soon as reasonably practicable. Keep a dated record of when you fitted each alarm, when you tested it and any fault reports, because that is the evidence a council would ask for.
