Up in smoke: 3.6 million Brits living without smoke alarms

• 3.6 million adults say their home doesn’t have a smoke alarm fitted
• Less than one in four (24%) test their smoke alarms monthly, as recommended 
• 41% of parents haven’t educated their children on what to do in a fire 
• A quarter of Brits (27%) admit they have disconnected their smoke alarms from the mains or removed the batteries and 14% have covered them with a bag or other material.

New research from Direct Line home insurance¹ reveals a worrying gap in home fire safety, as millions of Brits admit their home doesn’t have smoke alarms, and others don’t know if their smoke alarms are in working order. Whilst the majority (92%) of people say that their home does have smoke alarms, that leaves 3.6 million² adults living in homes without them.

Of those with smoke alarms, just a quarter (24%) test them monthly as recommended by fire safety experts³. A further 3 million (6%) aren’t sure whether their smoke alarms work⁴, and 15.1 million (27%) only have them in one room.⁵

Worryingly, more than two fifths (41%) of parents say they haven’t educated their children on what to do in the event of a fire at home.  

Direct Line’s analysis of 2024/25 government fire data⁶ reveals the main reasons smoke alarms failed to operate in home fires that caused casualties. In 5% of cases, the smoke alarm had no battery or a defective battery. In a further 15% of cases, the fire was in part of the home not covered by smoke alarms or the fire did not reach the alarm (48%), showing the importance of having them in all rooms. In 3% of cases, the smoke alarms had been incorrectly installed, and in a further 4% they had been prevented from operating correctly.

Worryingly, more than a quarter of Brits (27%) admit that they have disconnected their smoke alarms from the mains or removed the batteries, nearly one fifth (18%) have ignored the alarm while it was going off, and 14% have covered their smoke alarm with a bag or other material.

Beyond smoke alarms, the research reveals a lack of broader fire safety measures in British homes. Only a quarter of people (26%) have easy access to a fire extinguisher at home, one in five (20%) have a fire blanket in their kitchen, and just 1 in 17 (6%) have an escape ladder, which are all critical safety tools that could prove lifesaving in an emergency.

Dan Simson, Head of Direct Line Home Insurance, said: "Smoke alarms are your first line of defence in a fire, and it is crucial that they are in working order at all times. Many Brits do not have smoke alarms installed, and too many are failing to test them regularly, with nearly a fifth of people who have a smoke alarm not testing it in over six months. 

“With recent Aviva research⁷ finding that candle fires peak during the festive period, we urge all households to check their smoke alarms and to replace flat batteries promptly. Fire safety isn't just about having the equipment; it's about maintaining it to ensure the safety of people and property."
