Coverage first
Position alarms so fire is detected and occupants can hear the warning
A single alarm may not protect a multi-storey or extended home. Consider bedrooms, living rooms, open-plan layouts, loft conversions, basements and closed doors as well as halls and landings.
Rented-property regulations set minimum alarm duties, but the suitable provision can be greater depending on the property, licence, risk and relevant housing guidance.
Mounting position
Ceiling position and clear space affect smoke reaching the sensor
GOV.UK general home guidance describes the ideal position as on the ceiling, in the middle of a room, and on hallways and landings. The manufacturer gives exact clearances from walls, lights, beams, vents and other obstructions.
Do not guess a wall position or conceal an alarm above cupboards, curtains or decorative features. Sloping ceilings and unusual layouts need the product’s specific instructions or competent advice.
Avoid nuisance sources
Do not put ordinary smoke alarms where normal steam or fumes will repeatedly reach them
Kitchens and bathrooms can produce cooking aerosol, smoke, steam and condensation. A suitably selected heat alarm may be used in a kitchen as part of a wider alarm arrangement.
Avoid positions affected by strong draughts, extract fans, heating vents, extreme temperature, dust or insects unless the product is designed for the environment.
- Every relevant storey considered
- Hall and landing warning path covered
- Kitchen uses a suitable alarm type
- Bathroom steam kept away from smoke alarms
- Sound can be received in sleeping rooms
- Specialist visual or vibrating warning considered where needed
After fitting
Test audibility, interlinking and future access
Test each alarm using its approved control and confirm linked units and specialist alerts operate. Make sure the device can be safely reached for testing, cleaning and replacement.
Review provision after extensions, loft conversions, room changes, new tenants or occupants with different warning needs. Never relocate an alarm solely to stop nuisance activation without checking the resulting coverage.
