Smoke alarms will alert you early to a fire, giving you time to escape and call 999. 

Learn how to protect your home with properly installed, working smoke alarms. Check out our tips on choosing, testing, and maintaining the right smoke alarm for your needs. 

Choosing a Smoke Alarm

When it comes to picking a smoke alarm, we always recommend going for a battery powered one. They are available to buy from as little at £10* from most DIY stores and online. 

Ideally, look for an alarm with a 10-year sealed battery, as it takes the hassle out of changing batteries. That said, alarms with replaceable batteries are still a good option, just remember to check and change them regularly. 

Whichever type you choose, make sure it has the British Standards Kitemark or the European CE mark. These show the alarm meets safety standards and has been properly approved

Fitting a Smoke Alarm

Fit a smoke alarm on every level of your home, ideally on the ceiling of a hallway and landing.   

Smoke alarms should always be mounted on the ceiling, near the middle of the room or hall, and at least 30cm away from a wall or light. 

Testing Your Smoke Alarm

To keep your smoke alarms in good working condition:  

  • Test once a month by pressing the button until the alarm sounds 
  • Change the battery once a year (unless it’s a ten- year alarm) 
  • Clean your smoke alarm every three months to remove dust and help prevent false alarms. 

IMPORTANT TIP: Most smoke alarms need to be replaced every 10 years. Is yours due for an upgrade?
