The Fitness for Human Habitation (Wales) Act comes into effect on 15 July this year (effective to all landlords, social and private).

The act identifies 29 hazards within the property where landlords need to meet minimum requirements.
The FFHH act requires a smoke alarm, in proper working order, to be present on every storey of a dwelling.

Landlords must ensure that each of these alarms are in proper working order and interlinked with all other smoke alarms connected to the electricity supply.

Landlords may consider it appropriate to install more that one smoke alarm on each store along with a heat alarm in the Kitchen, these additional alarms could be mains or battery powered. Any additional battery-powered alarms do not need to be interconnected (Although, BS 5839-6 recommends interconnecting all alarms within the dwelling).

The act signposts landlords to BS 5839-6 for recommended guidance on the installation of alarms
A Carbon Monoxide alarm should be installed in all rooms containing a fuel-burning appliance (including cookers).

CO alarm can be mains or battery-powered and must comply with BS EN 50291. Siting should be carefully considered noting the expiry date of the alarm.
