London Fire Brigade Approach to Automatic Fire Alarms

From 1 October 2024 the London Fire Brigade (LFB) will no longer be attending Automatic Fire Alarms (AFAs) between the hours of 07:00 – 20:30 in commercial properties – unless a call is also received from a person reporting a fire.    

The London Fire Brigade will continue to always respond to all automatic fire alarms in residential buildings and in schools, nurseries, hospitals, care homes, heritage sites, and other exempt premises (a full list of exemptions to this policy is at the end of this page).  LFB will continue to always attend when called to a fire by a member of the public and to AFAs between 20:30-07:00. 

In preparation of the roll out of the policy on 1st October businesses should understand their fire safety responsibilities and make sure they are prepared to take action.

For more information about the policy, including advice for business owners and responsible people, please visit the London Fire Brigade FAQ page 

Why are the London Fire Brigade changing its policy on AFA attendance? 

In 2023/24 automatic Fire alarms made up 40 per cent of all LFB incidents attended – 52,000 calls.  Less than one per cent of calls from non-residential AFAs are ultimately recorded as fires – 99 per cent are false alarms. This is not a good use of resources and by not attending AFAs where there is no sign of a fire, LFB will be able to use this additional time for operational training and to increase fire prevention in local communities. This will include additional fire safety checks in homes and businesses, premises familiarisation visits and understanding, reducing and preparing for specific local risks, such as wildfires or flooding.     

This change in policy is in line with nearly all other Fire and Rescue Services. These changes are being introduced in London following a consultation held last year with members of the public, businesses, partners and LFB staff.  

Over the coming months, in advance of the roll out of the policy, LFB will be sharing key information and reaching out to organisations, businesses and individuals who are responsible for fire safety in buildings to make sure they understand their responsibilities and take action to be prepared for the change in policy.  

LFB will review and monitor the impact of the new policy as it rolls out to ensure it is working as intended, and we will make adjustments if any issues are identified.     

If you have any questions or would like any additional information on the change in policy, please email Dipika Chowdhury, the London Fire Brigade Business Engagement Co-ordinator at
