Smoke Alarms

Working smoke alarms save lives, make sure you're up to date with the latest smoke alarm safety advice.


  • Install a smoke alarm on every level of your home

  • Test the alarms every week to make sure they are working

  • The best places to fit them are at the bottom of the stairs, with further alarms on each stair landing

  • The ideal position is on the ceiling, as near as possible to the center of the room, hallway or landing

  • Take time to check on elderly relatives and neighbors as they are at greater risk from fire, and test their smoke alarms for them   

Looking after your smoke alarms

  • Once a week – test the batteries

  • Once a year – change the batteries (unless it is a ten-year alarm)

  • Twice a year – gently vacuum to remove

  • Every ten years – replace the entire smoke alarm
