Why records matter
GOV.UK guidance for England says relevant landlords must equip CO alarms in rooms used as living accommodation that contain fixed combustion appliances, except gas cookers. A clear record helps show what was checked, when access was provided and what remedial action was recommended.
CO alarm rules and practical evidence
For rented homes in England, official guidance explains that relevant landlords must ensure carbon monoxide alarms are equipped in rooms used as living accommodation that contain a fixed combustion appliance, excluding gas cookers. It also says faulty prescribed alarms must be repaired or replaced once the landlord is informed and the fault is found.
GOV.UK guidance says the regulations do not stipulate the alarm type, but landlords should choose suitable alarms and consider BS 50291. Placement should follow manufacturer instructions; the guidance says CO alarms are generally positioned at head height, around 1 to 3 metres from a possible source of carbon monoxide.
