Fire Safety Trends Report 2025: Emerging Risks Reshaping UK Business Protection
A Changing Risk Landscape
The traditional fire triangle (heat, fuel, and oxygen) remains unchanged. What is transforming is the nature of each element in modern buildings. Today's workplaces contain energy-dense battery storage, sophisticated electrical systems, and new construction materials that behave differently in fire conditions than their predecessors.
Meanwhile, regulatory enforcement has intensified following high-profile incidents, with authorities wielding stronger powers and showing increased willingness to use them. The result? Businesses that once considered themselves compliant are discovering dangerous gaps in their fire safety strategies.
Trend 1: The Lithium-Ion Battery Challenge
The Hidden Hazard in Every Building
Lithium-ion batteries have quietly become one of the most significant fire risks in UK businesses. From laptops and phones to e-bikes and power tools, these energy-dense devices are everywhere, and they are causing fires at an alarming rate.
Key Statistics:
Battery fires are increasing significantly across all sectors
Thermal runaway can reach extreme temperatures within seconds
Traditional extinguishers are often ineffective against battery fires
According to BRE data, DC isolators are involved in 49% of PV system fire incidents
What Makes Battery Fires Different
Unlike traditional fires, lithium-ion battery incidents involve:
Thermal runaway: Self-sustaining heat generation that's difficult to stop
Toxic gas release: Including hydrogen fluoride and other corrosive gases
Re-ignition risk: Batteries can reignite hours or days after initial suppression
Stranded energy: Damaged batteries retain dangerous charge levels
Risk Mitigation Strategies
Immediate Actions:
Audit all battery charging locations in your premises
Implement dedicated charging stations away from escape routes
Install smoke and CO detection in all charging areas
Never leave batteries charging in unoccupied buildings
Store batteries at less than 60% charge when not in use (as recommended in RISCAuthority guidance)
Long-term Considerations:
Invest in specialist suppression systems for high-risk areas
Create battery storage protocols with proper containment
Train staff on battery fire response (evacuation, not firefighting)
Consider Aqueous Vermiculite Dispersion (AVD) extinguishers for first-response capability
Trend 2: EV Charging Infrastructure Risks
The Parking Revolution's Fire Safety Impact
As businesses install EV charging points to meet sustainability goals and employee demands, they are inadvertently creating new fire risks that existing safety systems weren't designed to handle.
The Challenge:
EV fires burn significantly hotter and longer than petrol vehicle fires
Require substantially more water to extinguish
Underground and multi-storey car parks can trap heat and smoke
Thermal runaway can potentially spread to adjacent vehicles
Critical Considerations for EV Charging Areas
Infrastructure Requirements:
Enhanced ventilation systems for enclosed charging areas
Increased water supply for firefighting operations
Thermal barriers between charging bays
Specialist detection systems for early warning
Policy Adaptations:
Updated evacuation procedures accounting for intense smoke
Clear marking of EV locations for emergency responders
Restricted charging in high-risk locations
Regular inspection of charging equipment
Trend 3: Solar Panel Fire Risks
When Green Energy Creates Red Alerts
With solar installations now common across UK buildings, PV system fires represent an emerging risk that many businesses haven't properly assessed.
Risk Factors (from BRE study data):
DC isolators involved in 49% of incidents
Inverter failures account for 19% of incidents
Hot spots from dirt/bird droppings causing panel degradation
Structural loading issues with ballasted systems
The Firefighting Dilemma
Solar panels create unique challenges:
Continue generating power even when grid is isolated
DC voltage present during firefighting operations
Difficult access for fire suppression
Risk of roof collapse from water loading
Essential Controls:
Annual infrared thermography inspections
Implement cleaning schedules (bird droppings are critical)
Install DC isolation switches accessible to firefighters
Maintain 2.5m separation at compartment walls (as per RISCAuthority guidance)
Ensure adequate structural assessments for ballasted systems
Trend 4: Regulatory Evolution Post-Grenfell
The New Enforcement Reality
The Fire Safety Act 2021 and Building Safety Act 2022 have fundamentally changed the compliance landscape, with ripple effects still being felt across all sectors.
What's Changed:
External walls and balconies now included in risk assessments
Responsible Person definition expanded and clarified
Information sharing requirements between building owners
Personal liability for company directors increased
Fire door compliance under intense scrutiny
The 75% Failure Rate Crisis
According to the Fire Door Inspection Scheme (FDIS), 75% of fire doors fail to meet UK standards, with common failures including:
Excessive gaps (77% of failures)
Maintenance issues (54%)
Smoke seal problems (37%)
Improper installation (31%)
Compliance Actions Required:
Implement quarterly fire door checks for high-traffic doors
Maintain photographic records of all fire doors
Document all maintenance and repairs
Ensure certification for all new installations
Create remediation plans for identified issues
Trend 5: The Insurance Industry Response
When Compliance Isn't Enough
Insurance companies are increasingly implementing their own fire safety requirements that often exceed legal minimums, driven by rising claim costs and frequency.
Emerging Insurance Trends:
More frequent inspection requirements
Demands for photographic evidence of compliance
Third-party verification of systems becoming standard
Specific requirements for battery storage areas
Enhanced business continuity planning expectations
The Coverage Gap Risk: Businesses are discovering post-incident that their insurance may be compromised due to:
Unreported modifications to buildings
Failure to maintain systems to insurer standards
Inadequate documentation of compliance activities
Changes in building use not communicated
Trend 6: Smart Building Integration Challenges
When Innovation Increases Risk
Modern building management systems offer efficiency but create new vulnerabilities:
Integration Risks:
Cyber attacks potentially disabling fire systems
Over-reliance on automated systems
Complex interactions between building systems
Single points of failure in networked systems
Mitigation Strategies:
Maintain manual override capabilities
Regular cyber security assessments
Isolated networks for critical safety systems
Comprehensive staff training on system failures
Trend 7: Climate Change Impact
Extreme Weather's Fire Safety Implications
Climate change is creating conditions that challenge traditional fire safety approaches:
Emerging Challenges:
Increased lightning strikes requiring enhanced protection
Flooding damaging fire safety systems
Heat waves stressing electrical systems
Storm damage compromising compartmentation
Adaptive Measures:
Enhanced lightning protection systems
Flood-resilient equipment positioning
Increased maintenance during extreme weather
Emergency plan updates for compound events
