Fire and rescue services in England attended 178,003 false alarms caused by fire alarms or firefighting equipment operating in error in the year ending June 2026, up 3.2% on the previous year, according to the government’s false alarm figures.
For housing providers, landlords and installers, reducing unwanted activations starts with suitable detection, correct installation and regular maintenance. This guide outlines the practical checks that can help.
Why reducing false alarms matters
Repeated false alarms disrupt residents, generate maintenance visits and can reduce confidence in fire detection. London Fire Brigade warns that frequent false alarms can lead to complacency, making people less willing to respond quickly when an alarm sounds.
Reducing unwanted activations helps protect that confidence and reduces unnecessary demands on fire service resources.
Choose suitable detection for each location
Cooking fumes, steam and dust can contribute to unwanted activations, so choosing the right alarm type matters. Smoke alarms detect smoke, while heat alarms respond to a rise in temperature.
Use heat alarms rather than smoke alarms in kitchens, where cooking fumes can cause unwanted activations. Heat alarms can also be suitable for garages and unoccupied lofts or attics, subject to the manufacturer’s instructions and the conditions in the space. Avoid installing smoke alarms in bathrooms or close enough to bathroom doors for escaping steam to trigger them.
When selecting and positioning detection, consider how each space is used and follow the manufacturer’s guidance for the intended application.
Where false alarms recur, ask a competent installer or maintenance provider to review the detector type, its position and any nearby sources of fumes, steam or dust. Any changes must maintain the required fire protection and be assessed for the individual property or building.
Follow the alarm’s installation and maintenance instructions
Correct positioning, testing and cleaning all contribute to effective alarm management. Follow the manufacturer’s instructions for the specific model.
As outlined in Hispec’s guide to common fire alarm issues, dust and small insects inside a smoke alarm’s detection chamber can trigger unwanted activations. Follow the product’s cleaning instructions and seek technical support if the issue continues.
Identify the cause of recurring false alarms
Record which device activated, when it happened and any activity taking place nearby. This gives installers and maintenance teams useful information when identifying patterns and investigating the cause.
Once an activation has been confirmed as a false alarm, review what caused it rather than treating it as routine. London Fire Brigade recommends investigating each occurrence and working with alarm maintainers to identify the cause and prevent recurrence.
For housing providers, residents should also have clear instructions on testing, reporting problems and responding to an alarm in line with the building’s fire safety procedures. Previous false alarms should never be a reason to ignore or disconnect an alarm.
