Smoke Alarms

Smoke alarms could help save your home, and your life. Test them weekly and never remove the batteries.

If you are contacting us concerning the changes in legislation relating to fire and smoke alarms introduced by the Scottish Government, please visit the Scottish Government website where you will find further information and a list of frequently ask questions.


How many smoke alarms does my home need?

In February 2019, the legislation relating to smoke detection in the home changed. This means all domestic properties in Scotland, regardless of tenure, should have the same levels of detection; increasing fire safety - Fire and Smoke Alarms in Scottish Homes  

Your home should have: 

  • One smoke alarm installed in the room most frequently used for general daytime living purposes
  • One smoke alarm in every circulation space on each storey, such as hallways and landings
  • One heat alarm installed in every kitchen

If your home is on one level – a flat or bungalow – you need to fit at least two smoke alarms. If your home has more than one level, you’ll need one on each floor, plus the living room.

All alarms should be ceiling mounted and interlinked.

Where should I fit smoke alarms?

The best place for a smoke alarm is on the ceiling. Try and keep them 30cm (12 inches) away from any walls, lights, doors, heating or air-conditioning vents.

Test the alarm to make sure you can hear it loud and clear from every room in the house – even with the doors closed. If you can’t hear it, move it or fit more alarms. Ideally you want to have an alarm within 7 metres (22 feet) of the living room door and 3 metres (9 feet) of a bedroom door.

In homes with more than one level, fit alarms in the downstairs hallway and on every stair landing.

For extra safety, fit smoke alarms in the bedrooms too – this can help protect you while you sleep.

How do I stop false alarms?

Try not to fit smoke alarms too close to the kitchen door – steam and cooking fumes are the most common cause of false alarms.

You can get some smoke alarms that are specially designed for use close to kitchens. Others have ‘silence’ buttons that will stop the alarm sounding for a short time while the air clears.

You should have a heat alarm in your kitchen.  Heat alarms can be used in places where there might be lots of steam or other fumes.

What tools and other bits will I need?

If fitting an alarm yourself, the alarm will come with screws and rawl plugs (the plastic sleeves needed when putting screws into plasterboard). You’ll need a screwdriver and possibly a drill. Read the instructions that come with the alarm for further information.

Looking after your smoke alarms


  • Take the batteries out, even for a short time
  • Paint over or put stickers on the smoke alarm

Every week

  • Test your smoke alarm by pressing the ‘test’ button. If it doesn’t sound, fit a new battery. If it still doesn’t sound, fit a new alarm

Every year

  • Replace the battery (unless you have a special ‘long-life’ alarm with a built in battery). Choose a date you’ll remember easily to do this, like a birthday or anniversary
  • Keep it clean and dust free. Gently vacuum the inside and outside casing. If you’re decorating or doing something that creates a lot of dust, use an elastic band to secure a plastic bag over the smoke alarm casing – don’t forget to take it off when you’re done

Every ten years

  • Replace each smoke alarm. The material inside smoke alarms that makes them work gets tired as it gets old.


Research has shown that children can remain asleep when smoke alarms are sounding.  If there are children in your home your escape plan should include adults ensuring that any sleeping children have been roused from sleep.


Additional support for you or other people

Do you or someone you know have additional support needs?

There are special alarms for older people, people with disabilities or other special needs. Things like mains-powered smoke alarms with back-up batteries, and even vibrating pads and flashing lights that warn people who can’t hear well.

And, if you think someone would need help to escape a fire it’s important they have a way of calling for help. This could be a phone that’s been set up with a one-touch or automatically dialled emergency number, or it could be a private or local authority assistance alert scheme.
