Smoke And Carbon Monoxide Alarms: The Small Compliance Item That Creates Big Disputes

The issue: GOV.UK's landlord guidance for the Smoke and Carbon Monoxide Alarm Regulations explains the expectations around smoke alarms and carbon monoxide alarms in rented homes. The equipment is simple. The failure mode is usually operational: nobody can prove what was checked, when, and what happened when a tenant reported a fault.

Every managed property should have a clear alarm record. At minimum, log the alarm locations, device type, installation or replacement date, test date, battery or sealed-unit status, and any tenant fault report. If a contractor attends for other works, adding an alarm check can prevent a separate visit and a later argument.

Carbon monoxide risk deserves particular care around fixed combustion appliances. Boiler cupboards, rooms with solid fuel appliances and other relevant spaces should not be treated as generic tick boxes. If an alarm is damaged, missing or expired, replacement should be immediate and documented.

The handover process matters too. At the start of a tenancy, testing alarms is useful only if the result is recorded. During occupation, tenants should know how to report a fault and property managers should have a route to replace defective alarms without drama.

The commercial point is blunt: alarms are cheap, disputes are not. A missed alarm record can become a complaint, an enforcement issue or a reputational problem that should never have reached the expensive stage.

GEM's operator view: smoke and CO alarms belong in planned maintenance calendars and visit checklists. The best system is boring: check, photograph where useful, record, replace when needed, and close the evidence loop.
