Government data shows widespread failures in home smoke alarms
Over 12,000 residential fires occur each year in the UK in homes without smoke alarms, according to Safety Group.
The organisation cited government data indicating that more than 470 people have died since 2019 in house fires where no alarm was present or the alarm failed to function.
According to the same data, smoke alarms only activated in 36 per cent of house fires, with many failing to sound due to battery or maintenance issues.
Safety Group said the findings reveal a gap between reported alarm ownership and actual alarm functionality.
The data show that while around 90 per cent of homes report having smoke alarms, only 70 to 75 per cent of these are working.
Alarms fail due to age, poor maintenance or incorrect placement
Safety Group UK reported that many UK homes are equipped with outdated or poorly maintained smoke alarms.
The organisation explained that smoke alarms generally have a lifespan of about 10 years, after which their effectiveness declines.
It recommended checking the manufacture date and replacing alarms that are close to or past their expected lifespan.
Safety Group added that devices may also fail to work due to dust or insect obstruction, flat smoke alarm batteries, or incorrect installation location.
It recommended placing alarms on ceilings away from fixtures and testing units monthly.
Interconnected alarms can provide early alerts across properties
Safety Group UK advised upgrading to interconnected smoke alarm systems.
These systems are designed to trigger all alarms in the home simultaneously when one detects smoke.
The company stated that this can provide additional seconds for safe evacuation, particularly in multi-level homes.
According to the organisation, both wired and wireless models are available, with wireless systems offering easier retrofitting for existing homes.
Some newer systems can also alert residents through mobile phone notifications.
Fire services advise regular testing and evacuation planning
Fire England recommends testing all smoke alarms every month by pressing the test button for a few seconds.
Safety Group UK supported this advice and suggested making testing a regular household activity.
The organisation also stressed the importance of replacing batteries annually and keeping spare batteries dedicated to alarms only.
In addition, it encouraged households to develop clear escape plans, including two exits per room and support roles for residents with additional needs.
