A new study has revealed a worrying gap between fire safety advice and real-world behaviour in UK homes – and the consequences could be fatal.
Research from Electrical Safety First has found that around four million adults in the UK admit to never testing their smoke alarms.
Despite expert recommendations that alarms should be checked every month, only 22% of people do so.
Almost one in ten test theirs just once a year or less.
These are not just statistics.
They represent millions of households where a working smoke alarm – one of the simplest and most effective life-saving tools available – may fail at the moment it is needed most.
The Numbers Behind the Risk
Government fire data analysed as part of the research makes the stakes clear.
Nearly 20% of accidental electrical dwelling fires occurred in homes without a working smoke alarm.
An electrical fault in the middle of the night, in a home where the smoke alarm hasn’t been tested in years, gives occupants little to no warning and dramatically reduces the time available to escape safely.
Guiseppe Capanna, product safety engineer at Electrical Safety First, put it simply: fires don’t discriminate.
Many people affected by fire say they never thought it would happen to them – which is precisely why regular testing matters.
Taking a few seconds each month to press the test button on your alarm could be the difference between a safe escape and a tragedy.
A Family’s Lucky Escape
The importance of working alarms was brought into sharp focus by a recent incident in Derbyshire in late 2025, where a family narrowly escaped a house fire believed to have been started by an e-bike battery.
The fire broke out in the middle of the night, but working smoke alarms triggered in time for the family to escape – forced to climb from a first-floor window to safety.
Without those alarms, the outcome could have been very different.
Where Are People Least Likely to Test?
The research also identified the UK cities where residents are least likely to test their smoke alarms regularly.
Sheffield came out worst, with around 14% of residents testing regularly, followed by Liverpool at around 11%, London at 9%, and Bristol and Cardiff both around 8%.
If you live in one of these cities, the message is especially pertinent – but complacency is a risk everywhere.
How Many Alarms Do You Actually Need?
One of the most important points raised by Electrical Safety First is that having a smoke alarm isn’t enough on its own. Alarms need to be positioned in the right places.
There should be at least one on every floor of the property, and ideally placed in areas where a fire is most likely to start.
The more alarms fitted, the earlier the warning — regardless of where in the home a fire begins.
What You Should Do Right Now
The advice from fire safety experts is straightforward.
Test your smoke alarms monthly — it takes seconds.
Make sure you have at least one alarm on every floor of your home.
Never ignore a low-battery beep; a chirping alarm is telling you something needs attention, not to be dismissed.
And ensure your alarms are maintained correctly — if you’re unsure whether your system is functioning as it should, have it checked by a qualified professional.
Simple, preventative actions like these cost very little time and nothing in terms of expense. The cost of not taking them can be immeasurable.
