Smoke alarm ownership statistics: reported household coverage

Surveys use different questions to describe smoke alarm coverage. A household reporting an alarm, a person reporting that their household has a working detector, and a tested device are distinct measures. The CPSC survey’s weighted U.S. household responses found 44.2% reported smoke alarms only, 54.4% reported both smoke and carbon monoxide (CO) alarms, and 98.6% reported smoke alarms in total. Fieldwork covered January 1–May 30, 2019 and March 23, 2021–February 16, 2024. Source: CPSC SCOA Use and Functionality in U.S. Households Survey

In the UK public preparedness survey, 78% of respondents in 2026 reported having a smoke detector at home, compared with 77% in 2025. All-respondent bases were 10,791 in 2026 and 10,536 in 2025. This is a respondent report, not an inspection of dwellings, and its question differs from CPSC’s household alarm-type measure.

Statistics Canada found that 98% of Canadians overall lived in a household with a working smoke detector in 2014. Selected provincial figures were 95% in British Columbia and 99% in Newfoundland and Labrador and Ontario. The measure is people reporting a working detector in their household.

Smoke alarm ownership statistics by housing tenure and household groups

Statistics Canada’s 2014 results show 99% of people in owner households and 97% in renter households reported a working detector in their household. By respondent age, the reported values were 97% for ages 15–24, 98% for ages 25–54, 98% for ages 55–64, and 97% for ages 65 and older. Age refers to the respondent, not necessarily the household reference person. Source: Statistics Canada, Emergency preparedness in Canada, 2014

The same survey reported 95% for household income under $20,000, including income loss, and 98% for $20,000 to under $40,000. Each listed band from $40,000 upward was 99%: $40,000 to under $60,000, $60,000 to under $80,000, $80,000 to under $100,000, $100,000 to under $150,000, and $150,000 or more. These are reported category values for people whose household had a working detector. Source: Statistics Canada, Emergency preparedness in Canada, 2014

Historical English Housing Survey results use an all-household base and report at least 1 working smoke alarm. In 2013–14, coverage was 94% for housing-association households, 91% for local-authority tenants, 88% for owner occupiers, and 82% for private renters. It was 91% for couples with dependent children and 83% for single households under age 60. Source: English Housing Survey: Fire and fire safety, 2013–14

Other 2013–14 English household comparisons: 85% of households with a household reference person (HRP) younger than 35 had at least 1 working alarm. The figure was 89% for households with a white HRP and 82% with an ethnic-minority HRP. By HRP employment status, it was 80% for unemployed, 87% for part-time employed, 88% for full-time employed, and 89% for retired. By dwelling type, it was 89% in houses and 84% in flats. These are historical survey reports, not later-year estimates or direct device inspections. Source: English Housing Survey: Fire and fire safety, 2013–14

Smoke alarm ownership statistics: working alarms and household confidence

In England, 93% of households reported at least 1 working smoke alarm in 2024–25, compared with 92% in 2023–24. For 2024–25, the reported shares were 97% among social renters, 93% among private renters, and 92% among owner occupiers. These are self-reports of working-alarm presence, not physical functionality tests. Source: English Housing Survey 2024 to 2025: Chapter 1, Housing quality

The CPSC survey’s weighted U.S. estimate was that 84% of households had at least 1 fully functional smoke or CO alarm, with a reported margin of error of ±3 percentage points. This combines smoke, CO and combination systems. A household-level proportional allocation estimated that 15% had alarms present but none tested working, while 1% had no alarms in the house. Source: CPSC SCOA Use and Functionality in U.S. Households Survey

Perceptions and test results were not identical. Among U.S. households with smoke alarms, 89% believed most or all were working, 8% believed not all were working, and 4% did not know. Among households that believed all tested alarms worked, 16% nevertheless had at least 1 alarm problem during testing. Source: CPSC SCOA Use and Functionality in U.S. Households Survey

In England in 2014–15, among households with smoke alarms, 93.8% reported all alarms working, 3.4% reported some not working, and 2.8% reported none working. Within alarm-owning households, 6% of private renters had non-working alarms, compared with between 2% and 3% in other tenure groups.

Scottish figures describe broader fire-detection and warning equipment criteria. In 2024, 76% of the 702,000 dwellings below the Tolerable Standard lacked satisfactory equipment, around 532,000 dwellings. Separately, a 2022 FOI response reported around 1.91 million homes, or 75%, with fully compliant interlinked fire alarms; 25%, around 638,000 homes, lacked satisfactory fire-warning equipment. These are distinct periods and composite compliance measures, not simple ownership rates. Sources: Scottish House Condition Survey 2024; Scottish Government FOI release, 2022

Smoke alarm ownership statistics: alarm counts, power and placement

In England in 2014–15, 6.7% of households had no smoke alarms, 27.0% had 1, 45.0% had 2, and 21.3% had 3 or more. A separate English measure found that among households with a working alarm, 70% had 2 or more alarms installed in 2013–14, up from 56% in 2003–04. The latter denominator is households with a working alarm. Sources: English Housing Survey, Smoke Alarms in English Homes, 2014–15; English Housing Survey: Fire and fire safety, 2013–14

CPSC’s weighted composition of tested devices was 73% smoke-only and 17% smoke/CO combination alarms. Location and level results were unweighted and based on 1,314 tested alarms: 31% were in hallways outside bedrooms, 19% in other hallways, 17% in living or family rooms, 12% inside bedrooms, and 11% in kitchens. By level, 84% were on the first floor, 11% on the second floor, and 4% in basements. These device shares do not describe the percentage of households with alarms in those locations.

The connection classification is qualified: the report says interconnected status was likely because exact wiring was not checked. In England in 2014–15, among households with smoke alarms, ordinary batteries were reported by 41%, mains power by 21%, 10-year batteries by 13%, and battery-and-mains combinations by around 12%. These household categories may overlap where different alarms in one home use different power. For 2013–14, working alarms were reported as 67% battery-only, 21% mains-only, 11% battery and mains, and 2% part of a mains-powered security system; multiple responses were possible.

Among 703 smoke alarms closest to kitchens in the CPSC device test, 53% were within 10 feet of the stovetop, including 13% less than 6 feet away. This is a device-level distance measure for tested U.S. homes. Source: CPSC SCOA Use and Functionality in U.S. Households Survey

Smoke alarm ownership: testing and maintenance patterns

Among U.S. households with smoke alarms, CPSC respondents said 33% never used the test button, 20% tested yearly, and 18% tested every 6 months. More frequent reported intervals were every 3 months for 9%, monthly for 6%, and weekly for 1%. These are self-reported habits. Among households that never tested, 36% said they did not know how to test the alarms. Source: CPSC SCOA Use and Functionality in U.S. Households Survey

In England in 2014–15, 28% of households with alarms reported testing them at least monthly: 8% weekly and 20% less often than weekly but still at least monthly. Overall, 22% said they never tested. That share was 33% among private renters, 18% among owner occupiers, and 27% among social renters. Source: English Housing Survey: Smoke Alarms in English Homes, 2014–15

In the 2024–25 English Housing Survey, 24% reported never testing their smoke alarm, similar to 2023–24. By tenure in 2024–25, never testing was reported by 29% of private renters, 29% of social renters, and 22% of owner occupiers. The survey reports behavior but does not establish why households did or did not test. Source: English Housing Survey 2024 to 2025: Chapter 1, Housing quality

CPSC also found that 42% of U.S. households with smoke alarms reported a nuisance alarm in the prior 12 months. Among those reporting one, 77% cited cooking and 13% cited low battery as possible causes; respondents could select more than 1 cause. These are reports of experiences and possible causes. Source: CPSC SCOA Use and Functionality in U.S. Households Survey

Among U.S. smoke-alarm households, 79% considered their home very or mostly safe with current smoke alarms, including 51% who said very safe. SCOA Use and Functionality in U.S. Households Survey

English Housing Survey comparisons show increased reported working-alarm coverage between 2003–04 and 2013–14. The share of all households with at least 1 working alarm rose from 80% to 88%. Among private renters it rose from 70% to 82%, and among local-authority tenants from 77% to 91%. By property type, coverage increased from 71% to 84% for flats and from 81% to 89% for houses. Source: English Housing Survey: Fire and fire safety, 2013–14

Over the same English survey periods, coverage among households with an HRP aged 16–24 rose from 72% to 85%. For households with an ethnic-minority HRP, it increased from 67% to 82%; for white-HRP households, it rose from 81% to 89%. These are comparisons between the named survey periods, not a continuous annual series. Source: English Housing Survey: Fire and fire safety, 2013–14

The English survey found that households without a smoke alarm declined from 11% in 2008–09 to 7% in 2014–15. Data were not collected in 2009–10, so the endpoints do not form an uninterrupted annual series. Households with alarms present but none working declined from 4% to 3% over those endpoints. Among local-authority renters, that measure fell from 6% to 3%; among housing-association renters, it fell from 4% to 2%. Source: English Housing Survey: Smoke Alarms in English Homes, 2014–15

The CPSC comparison labels smoke alarms as present in 88% of households in the 1994 study and 99% in the 2024 study. Its report identifies the earlier figure as the 1992 Smoke Detector Operability Study, so the comparison label and earlier study reference use different year descriptions. These are study comparisons, not annual measurements. Source: CPSC SCOA Use and Functionality in U.S. Households Survey

Scotland’s 2024 estimate concerns satisfactory fire-detection and warning equipment among dwellings below the Tolerable Standard; its 2022 figure concerns fully compliant interlinked alarms across homes. Neither measure is equivalent to simple smoke alarm presence. Sources: Scottish House Condition Survey 2024; Scottish Government FOI release, 2022
