Where Must Smoke Alarms Be Installed?

At Least One Smoke Alarm on Every Storey
A smoke alarm must be installed on every storey of the property that is used as living accommodation.
This includes:
✔ Ground floors
✔ First floors
✔ Loft conversions used as living space
✔ Additional residential levels
The aim is to ensure occupants receive adequate warning regardless of where a fire starts.
What Counts as Living Accommodation?
Living accommodation typically includes areas such as:
- Living rooms
- Bedrooms
- Kitchens
- Dining rooms
- Hallways
- Landings
If a floor is used for residential living purposes, a smoke alarm is generally required.
Do Smoke Alarms Need to Be Installed in Every Room?
Not necessarily.
The legal requirement is generally for at least one smoke alarm per storey used as living accommodation.
However, landlords often choose to install additional alarms in:
- Living rooms
- Hallways
- Landings
- Bedrooms
- Kitchens (using suitable alarm types)
Additional alarms can provide enhanced protection.
Landlord Responsibilities

Landlords should encourage tenants to report any issues immediately.
Hard-Wired vs Battery-Powered Smoke Alarms
Several types of smoke alarms are available.
Battery-Powered Alarms

Sealed Long-Life Battery Alarms
- Batteries typically last up to 10 years
