the property is working correctly at the beginning of each new tenancy.


BRITISH STANDARDS For fire alarm installation, it is recom- mended to follow the British Standard BS 5839-6:2019+A1:2020. The standard lists three categories of a system to describe the level of protection the systems provide – generally the higher the category of system the higher the level of protection. For CO alarms, it is recommended to follow BS EN 50292 for installation. The standard states that CO alarms should be installed in any room that has any fuel burning appliances, rooms where people spend the most time – such as a living room; rooms where people sleep, and any room that has a flue running through it. This means that a CO leak can be detected from all the potential sources and heard throughout the property. There is not yet a confirmed date


when this new legislation will come into force in England, but it is expected to be around late 2022. It could, however, be earlier or later, so the most appropriate advice is to install the alarms at the earliest


opportunity, as it is expected that there will be no grace period for compliance.

ANY CO ALARM INSTALLED MUST COMPLY WITH BS EN 50291-1; THIS STANDARD SHOWS THAT THE ALARMS HAVE BEEN EXTENSIVELY TESTED TO ENSURE THEIR QUALITY INCLUDING SENSOR REACTION TIMES, MINIMUM ALARM SOUND LEVELS AND TEMPERATURE RESISTANCE
