After a Fire: Lessons From Recent UK Incidents Every Building Owner Should Learn

After a Fire: Lessons From Recent UK Incidents Every Building Owner Should Learn

Every serious fire in the UK triggers an investigation. Fire investigators, coroners, and sometimes public inquiries piece together what happened, why it happened, and what could have prevented it. These findings are not academic exercises. They are lessons written in the aftermath of real harm, injuries, displacement, and loss of life.

For building owners and managers, these lessons are invaluable. The same failures appear again and again across different building types, different locations, and different decades. Understanding these patterns and acting on them is one of the most effective things you can do to protect the people in your building.

This article draws on common themes from publicly available fire investigation reports, inquests, and official reviews. The focus is not on sensationalising individual incidents, but on extracting the practical lessons that every responsible person should learn.

Lesson 1: Disabled or Silenced Fire Alarms Cost Lives

What Goes Wrong

One of the most frequently cited factors in serious UK fire incidents is a fire detection system that was not functioning at the time of the fire. Sometimes the system had been deliberately disabled, often because of persistent false alarms that annoyed occupants or staff. Sometimes it had developed a fault that had not been reported or repaired. Sometimes it had simply never been maintained.

In care home fires, there are documented cases where staff silenced alarms and failed to investigate, assuming a false alarm. In residential buildings, individual flats have been found with detectors removed or with dead batteries. In commercial premises, alarm systems have been found isolated during building works and never reconnected.

What the Regulation Requires

The Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to ensure that fire detection and alarm systems are maintained in working order. British Standard BS 5839 sets out the requirements for the design, installation, commissioning, and maintenance of fire detection and alarm systems. This includes regular testing (weekly for alarm sounders, six-monthly for the full system by a competent person) and prompt repair of faults.

Deliberately disabling a fire alarm, for any reason, is a breach of the Fire Safety Order and potentially a criminal offence.

What You Should Do

Ensure your fire alarm system is regularly tested and maintained in accordance with BS 5839. If false alarms are a problem, investigate the root cause, dirty detectors, detectors sited too close to kitchens or bathrooms, or inappropriate detector types for the environment. Replace or relocate detectors rather than disabling them. Keep a log book of all tests, faults, and maintenance visits. Never allow an alarm system to remain in fault condition without immediate investigation and repair.

Lesson 2: Propped-Open Fire Doors Enable Fire Spread

What Goes Wrong

Fire doors are designed to contain fire and smoke within a compartment, protecting escape routes and giving occupants time to evacuate. They only work when they are closed. Yet fire investigation after fire investigation reveals doors that were wedged or propped open at the time of the fire.

In residential buildings, communal fire doors in corridors and stairwells are propped open for convenience, to improve ventilation, to make it easier to carry shopping, or simply because residents find them heavy. In commercial buildings, fire doors are propped open to ease the movement of goods or to improve airflow. In care homes, doors are held open to allow staff to observe residents.

When a fire starts, an open fire door allows smoke and flames to spread rapidly into areas that should have been protected. Escape routes fill with smoke. Compartmentation fails. What should have been a contained incident becomes a building-wide emergency.

What the Regulation Requires

The Fire Safety Order requires that fire doors are maintained and kept in good working order. Fire doors must be self-closing and must not be held open unless by an approved automatic release mechanism linked to the fire alarm system. Such hold-open devices close the door automatically when the alarm activates.

What You Should Do

Conduct regular checks of all fire doors in your building. Ensure self-closing devices are functioning correctly. Remove any wedges, door stops, or improvised hold-open devices immediately. Where there is a genuine operational need to keep fire doors open, such as in care homes, install approved electromagnetic hold-open devices connected to the fire detection system. Educate occupants about why fire doors must remain closed and the consequences of propping them open. Consider installing signage on fire doors reminding people not to prop them open.

Lesson 3: Missing or Inadequate Fire Risk Assessments

What Goes Wrong

The fire risk assessment is the foundation of fire safety management. It identifies the hazards, evaluates the risks, and sets out the measures needed to protect people. When a building does not have a fire risk assessment, or has one that is out of date, superficial, or carried out by someone without the necessary competence, the responsible person is effectively flying blind.

Inquests and investigations repeatedly find that buildings involved in serious fires either had no fire risk assessment at all, had one that was years out of date, or had one that failed to identify the very hazards that caused the fire. In some cases, the fire risk assessment existed on paper but its recommendations had never been actioned.

What the Regulation Requires

Article 9 of the Fire Safety Order requires the responsible person to carry out a suitable and sufficient fire risk assessment. It must be reviewed regularly and updated whenever there is a significant change to the building, its use, or its occupants. The assessment must be carried out by a competent person, someone with sufficient training, experience, and knowledge.

What You Should Do

Ensure your fire risk assessment is current, comprehensive, and carried out by a competent assessor. Review it at least annually, and after any significant change, building works, a change of use, a change in occupant profile, or a fire-related incident. Most importantly, act on the findings. A fire risk assessment that identifies significant risks but gathers dust in a filing cabinet provides no protection whatsoever.

Lesson 4: Inadequate Means of Escape

What Goes Wrong

When a fire starts, the ability to escape quickly and safely is the single most important factor in survival. Fire investigations regularly identify failures in escape provision: routes that were blocked by storage or rubbish, exit doors that were locked or obstructed, stairwells that were used for storage, external escape routes that were inaccessible, and buildings where the number or width of escape routes was insufficient for the number of occupants.

In commercial premises, fire exits are sometimes locked to prevent theft or unauthorised access. In residential buildings, communal corridors and stairwells become informal storage areas. In buildings with complex layouts, occupants may not know where the escape routes are because signage is missing or inadequate.

What the Regulation Requires

The Fire Safety Order requires the responsible person to ensure that routes to emergency exits and the exits themselves are kept clear at all times. Emergency doors must open in the direction of escape and must not be locked or fastened in a way that prevents them being easily and immediately opened by any person who may need to use them in an emergency.

What You Should Do

Inspect all escape routes regularly. Remove any storage, obstructions, or combustible materials from corridors, stairwells, and exit paths. Ensure all fire exit doors open freely, are not locked against escape, and have appropriate emergency hardware (push bars or panic bolts). Check that escape route signage and emergency lighting are in place and functioning. If your building has a complex layout, ensure occupants are familiar with escape routes through induction and regular drills.

Lesson 5: No Evacuation Plans for Disabled Residents

What Goes Wrong

This is one of the most troubling recurring themes in fire investigation findings. Buildings with disabled occupants, whether residential, commercial, or care settings, frequently lack adequate plans for evacuating people who cannot use stairs unaided. The default assumption that everyone will simply walk down the stairs is not just inadequate; it is discriminatory and dangerous.

Inquests have heard evidence of disabled residents who were unable to evacuate because there was no plan in place for their escape, no evacuation equipment available, no staff trained in assisted evacuation, and no communication with the fire service about their location within the building.

What the Regulation Requires

The Fire Safety Order requires the responsible person to consider the needs of all occupants, including those with disabilities, when planning emergency procedures. Personal Emergency Evacuation Plans (PEEPs) should be prepared for any individual who would have difficulty evacuating without assistance. The plan must identify what assistance they need, who will provide it, what equipment is required, and what the escape route will be.

For residential buildings, the Fire Safety (England) Regulations 2022 introduced specific requirements for responsible persons to provide information about evacuation to residents who may need assistance.

What You Should Do

Identify all occupants who may need assistance in an evacuation. Prepare a PEEP for each one, in consultation with the individual. Ensure appropriate evacuation equipment, such as evacuation chairs or refuge areas with communication systems, is available. Train designated staff or volunteers in assisted evacuation procedures. Share relevant information with the fire and rescue service so they know where vulnerable occupants are located. Review PEEPs regularly and whenever an individual's circumstances change.

Lesson 6: Outdated Fire Detection and Warning Systems

What Goes Wrong

Fire detection technology has advanced considerably over recent decades, yet many buildings still rely on systems that were installed years ago and have not been upgraded to reflect changes in the building, its use, or current standards. Common findings in fire investigations include detection systems that provided coverage to communal areas but not to individual flats, systems designed to a lower category than the building's current risk profile requires, and systems that had been extended or modified without proper design or commissioning.

In some cases, buildings that were originally low-rise have had additional floors added, or have changed use from commercial to residential, without corresponding upgrades to the fire detection system.

What the Regulation Requires

The fire detection system must be appropriate for the building and its use. BS 5839 sets out categories of system (from basic manual call point systems to full automatic detection in all areas) and provides guidance on which category is appropriate for different building types and risk profiles. The system must be maintained and upgraded when the building or its use changes.

What You Should Do

Have your fire detection system reviewed by a competent fire alarm engineer. Check whether the system category is appropriate for your building's current use and risk profile. If the building has been altered, extended, or changed in use since the system was installed, a design review is almost certainly needed. Plan and budget for upgrades where necessary. A system that met the standard when it was installed in 2005 may not meet the standard required for the building as it exists today.

The Common Thread

Across all of these lessons, a common thread emerges. The failures that lead to serious fires are rarely exotic or unforeseeable. They are ordinary, everyday lapses in maintenance, management, and vigilance. A fire door propped open. An alarm silenced. A risk assessment not reviewed. An escape route blocked. An evacuation plan never written.

These are not failures of engineering or technology. They are failures of management, of the responsible person not meeting the duties that the law places upon them. And they are preventable.

The human cost of these failures is real and devastating. People lose their homes, their possessions, their sense of security, and in the worst cases, their lives. Behind every fire safety statistic is a person who trusted that the building they lived or worked in was safe.

Taking Action

If you recognise any of these failures in your own building, the time to act is now, not after an incident, not after an enforcement notice, not after it is too late. Commission a thorough fire risk assessment. Fix the deficiencies it identifies. Maintain your fire safety systems. Train your people. Plan for the evacuation of everyone, including those who need assistance.

Fire safety is not a one-time exercise. It is an ongoing commitment to the people who occupy your building. The lessons from recent UK fires are there for anyone willing to learn them. The question is whether you will act on them before they become relevant to your building.
