Household fires pose a heightened threat, as per the largest fire service in the United Kingdom.

Modern Houses: An Unforeseen Fire Danger

The number of house fires in the UK is decreasing, yet a worrisome pattern is emerging – modern materials and home contents are causing faster, more destructive blazes. This alarming shift, evidenced by incidents like Grenfell and alarms raised by the fire service, necessitates a pressing review of fire safety building regulations for contemporary residential construction. Homeowners and renovators must now be informed of these emerging risks to secure the safest possible homes.

The Menacing Faces of Modern House Fires

Recent data reveals a drop in dwelling fires by 20% when compared to a decade ago, with 25,591 incidents recorded as of the year ending March 2024 in England alone.

However, fire-related fatalities within dwellings persist at an alarming rate. In the same aforementioned period, there were 180 fire-related casualties in England [source]. This disturbing disparity implies that while fires may be happening less frequently, they can be increasingly devastating when they do occur.

The Sinister Role of Modern Materials

The quest for energy efficiency, rapid construction, and innovative designs has fueled the adoption of materials that offer advantages in those areas but also hasten fire spread. These unsuspecting culprits can make ample fuel for a blaze.

The London Fire Brigade has published an assessment of fire risks, which unearths several culprits, including:

Timber Frame Construction: While promising speed and environmental benefits, modern timber structures, particularly cross-laminated timber buildings, pose a substantial fuel load. The open nature of timber stud walls allows fire to race through cavities rapidly [source].
Synthetic Cladding: The tragic Grenfell Tower fire brought into sharp focus the dangers of specific types of synthetic cladding, particularly Aluminum Composite Material (ACM) with a polyethylene core. The rapid spread of the fire was attributed to this combustible cladding by the Grenfell Inquiry Report [source].
Structural Insulated Panels (SIPs) and other composite materials: These modern construction staples, consisting of an insulating foam core sandwiched between structural facings, while boasting excellent insulation, can be combustible. This refers to the foam core and oriented strand board (OSB) used in their manufacture [source].
Lithium-ion batteries: With the rise of electric vehicles and solar panels, the lithium batteries they use pose a more significant threat to households. The Fire Protection Association expressed concern over the lack of safe disposal systems for lithium-ion batteries and the increasing number of electric vehicle fires [source].

The Fire Protection Association also warns that common household items made from "plastics and rubber" can burn relatively easily, serving as abundant sources of fuel [source].

This underscores the ominous prevalence of combustible synthetic materials in modern homes, which can contribute to the ferocity of a fire once it begins, no matter the building's design or construction.

The Clarion Call for a Broader Combustible Materials Ban

The horrifying fire at Grenfell Tower in 2017 starkly revealed flaws in the UK's building safety regulations. A critical issue was the use of highly combustible ACM cladding on the 24-story building.

As a response, a ban on the use of combustible materials in the external walls of buildings over 18 meters in height was introduced.

Led by Dame Judith Hackitt, the independent review emphasized the urgency of a "whole system change" in building regulations, rather than focusing solely on cladding issues. The Grenfell Inquiry's final report echoes this sentiment, advocating for a comprehensive fire safety approach that examines risks in all residential buildings, not just high-rise structures [source].

The Building Safety Levy aims to fund the remediation of unsafe cladding on higher-risk buildings, but homeowners and the renovating sector must heed the critical message: future regulations may impose restrictions on combustible materials across all residential properties, regardless of height.

Although not yet law, it's advised that homeowners consider materials with higher fire resistance ratings when building or renovating and remain mindful of other materials within their homes that may make fires spread more rapidly.

The decrease in house fires does not necessarily equate to safety, as modern materials in homes and their contents can accelerate fire spread, making blazes more destructive.
The transition toward energy-efficient and innovative designs has led to the increased use of materials like timber frame construction, synthetic cladding, and structural insulated panels in contemporary homes.
Such modern materials, while offering benefits, can serve as abundant fuel for fires, contributing to their rapid spread.
To mitigate this risk, a broader ban on combustible materials could be implemented in future building regulations, extending beyond high-rise structures.
Homeowners and renovators should prioritize materials with higher fire resistance ratings when building or renovating, to ensure the safest possible homes and adhere to future regulations.
A forward-thinking lifestyle and responsible approach to home-and-garden planning should include being informed about potential fire hazards posed by common household materials, such as plastics and rubber, to maintain a secure home environment.
