Carbon monoxide alarms
Carbon monoxide is invisible and has no smell. In England, landlords must fit a CO alarm in any room used as living accommodation that has a fixed combustion appliance (excluding gas cookers). CO alarms can be mains or sealed-battery, and some can interlink with smoke alarms.
