Where do I fit a smoke alarm

Where do I fit a smoke alarm

If you’ve made the correct decision and purchased an alarm the next stage is where in your property do I fit it.


  • Firstly always put the alarms where you will be able to hear them. Most fatal house fires occur during the night when the occupants are asleep. So make sure you site the alarm where you can hear it from the bedrooms and when doors are closed.
  • If your home is single storey i.e. flat or bungalow, then fit the alarm (s) between the living area and the bedrooms.
  • For homes spread over more than one floor i.e with a staircase present, we suggest putting an alarm at the bottom of the staircase and then on each and every landing.
  • The smoke alarms should be fitted as near as possible to the centre of the room/hall/landing. Make sure the alarm is positioned at least 30cm from the nearest light fitting.
  • Follow the manufacturer’s instructions on how to fit and service the alarm- they are normally fixed with screws direct into the ceiling.
  • For hard wired alarms i.e. those that are powered from the mains electricity supply, and are often linked, we suggest using a suitable qualified installer.


Where Do I not fit a smoke alarm or detector

  • Do not fit smoke alarms in or very near to the kitchen as it will likely be set off by cooking fumes. Remember you can purchase specilaist heat sensitive smoke alarms suitable for this position.
  • Similarly do not site one in or near the bathroom as the steam could well accidently set it off.
  • We do not recommend putting smoke alarms in garages as vehicle exhaust fumes will generally trigger these types of alarm.
  • Do not put your alarm inside a cupboard or wardrobe.
  • We do not suggest putting smoke detectors at height less than ceiling heights.
  • Do put put your alarm in the corner of rooms of where the air flow or air circulation is restricted
  • Over the stairwell as you will not be able to reach it to safely test and service it.
  • Don’t paint over your some alarm as it will restrict the passage of particles to the sensors.

Finally once you an alarm please make sure it continues to be working by testing it regularly and replacing the batteries.
