This guide examines the latest commercial kitchen fire statistics UK restaurant operators need to understand, including the leading causes, legal responsibilities and financial consequences of serious fires.
What the Latest Fire Data Reveals About UK Commercial Kitchens
Commercial kitchens are among the highest-risk fire environments in the hospitality sector. High-temperature cooking, hot fats and oils, electrical equipment and grease accumulation within extraction systems all create opportunities for ignition.
Once a fire enters grease-contaminated canopies, fans or ductwork, it can become extremely difficult to locate and control. In many UK buildings, extraction ductwork extends through several storeys, passing close to offices, flats and other occupied areas before reaching the roof. This creates the potential for serious structural damage and danger to life, particularly in older buildings with complex layouts and limited access.
Real incidents at well-known venues, including Lore of the Land, TGI Fridays in Edinburgh and Rodizio Rico at The O2 Arena, demonstrate how devastating commercial kitchen fires can be. You can read more about these real incidents on our website here.
This guide brings together the latest available official data and industry evidence on restaurant and kitchen fires, including their frequency, leading causes, legal responsibilities, arson risk and recent enforcement activity. Where figures relate specifically to England rather than the whole of the UK, this is clearly stated.

Restaurant and Kitchen Fires Remain a Persistent Commercial Risk
Fire and rescue services in England attended 1,275 fires in food and drink premises during 2024/25. The sector accounts for approximately 19% of workplace fires and ranks as the second-highest-risk workplace category, behind industrial premises.
This elevated risk reflects the conditions found in commercial kitchens. Restaurants, takeaways and catering premises combine sustained high temperatures with hot cooking oils and fats, powerful electrical and gas appliances, and grease accumulation inside canopies, filters, fans and extract ductwork.
Busy service periods can increase the danger further. Under pressure, routine cleaning, equipment checks and safe working procedures may be delayed or overlooked, allowing combustible grease and other hazards to build up.
Although workplace fires have fallen by approximately 29% over the past decade, commercial kitchens remain a consistently high-risk environment. The combination of frequent ignition sources, flammable materials and concealed grease deposits means that a small cooking fire can quickly develop into a serious incident affecting the entire premises.
Commercial Kitchen Fire Causes
Cooking is the leading cause of restaurant fires, accounting for approximately 25% of incidents. It is also a major ignition source in care homes, where cooking is linked to around 41% of fires.
Commercial kitchens contain several overlapping fire hazards. High temperatures, flammable oils, grease deposits, extraction ductwork and heavily used electrical equipment can allow a small incident to escalate quickly.
Cooking Fat and Oil Fires
Hot cooking fats and oils can ignite when they reach their ignition temperature. These fires require a suitable Class F extinguisher. Water and unsuitable extinguishers should never be used because they can spread burning oil and cause a violent flare-up.
Grill and Fryer Fires
Fryers and grills operate at consistently high temperatures and generate significant amounts of grease. Effective temperature control is essential because overheated oil can self-ignite, particularly where thermostats, safety cut-outs or equipment are poorly maintained.
Oven and Range Fires
Food debris, grease and fat can accumulate around burners, heating elements and inside ovens or ranges. These deposits provide a ready source of fuel and can ignite when exposed to sustained heat or open flames.
Grease-Contaminated Extraction Systems
Airborne grease can collect inside filters, canopies, fans and extract ductwork. If flames enter the system, these deposits can ignite and create a concealed route for fire to spread beyond the kitchen.
Professional inspection and cleaning are commonly required by insurance every three to twelve months, depending on the type of cooking, hours of operation and level of grease production.
Electrical Faults
Commercial kitchens rely on heavily used electrical appliances, often in hot and humid conditions. Damaged wiring, overloaded circuits, faulty equipment and inadequate maintenance can all create ignition sources.
Regular inspection, servicing and prompt repair by competent professionals are essential for reducing electrical fire risk.
Legal Requirements for Restaurant Fire Safety
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person for a restaurant, takeaway or catering premises must manage fire safety through a clear and documented process.
Core legal duties include:
- Completing and regularly reviewing a suitable and sufficient fire risk assessment.
- Installing, testing and maintaining appropriate fire detection and warning systems.
- Arranging professional inspection and cleaning of kitchen extraction systems and ductwork at suitable intervals.
- Providing staff with fire safety training, including guidance on evacuation procedures and the correct use of fire extinguishers.
- Appointing enough trained fire marshals or fire wardens to support fire prevention and assist with evacuation.
Fire safety audit results show why these duties matter. In England, approximately 58% of fire safety audits carried out during 2024/25 were judged satisfactory. This means a substantial proportion of audited premises did not fully meet the required standard.
The Cost of Non-Compliance
The financial consequences of a serious fire can be substantial. UK business fire insurance claims total approximately £940 million each year, while the average cost of a major business fire is estimated at around £657,074.
For restaurants and catering businesses, the cost of a suitable fire risk assessment, regular maintenance and properly trained fire wardens is small when compared with the potential losses caused by fire, business interruption, enforcement action and reputational damage.
Ecofleece Filters: Smarter Grease Control at Source
Commercial kitchen fire safety depends on more than responding to grease after it has accumulated. A preventative approach starts by capturing airborne grease at canopy level, before it can travel into concealed ductwork, extract fans and rooftop components.
Ecofleece Filters® uses a three-part commercial kitchen filtration system consisting of a frame, a metal baffle filter and a disposable 100% wool filter pad. Together, these components capture significantly more grease-laden vapour than a conventional metal baffle filter alone.
Ecofleece wool filter pads capture up to 98% of airborne grease* at source under tested conditions, significantly reducing the amount of combustible grease entering the extraction system. This can help lower grease-related fire exposure, protect fans, fire suppression and downstream equipment and support a cleaner, more manageable kitchen extract system.
Each replaceable Ecofleece wool filter pad is made from 100% natural wool. Wool has fibre properties that help capture and retain grease, while also providing a renewable alternative to synthetic filtration materials. The wool itself is natural and biodegradable, although used pads must be handled and disposed of appropriately because they contain captured fats, oils and grease.
Reactive Cleaning Vs Preventative Management
The image (above) highlights the clear difference between a reactive and preventative approach to commercial kitchen grease management. Without Ecofleece, grease can enter the extraction system, leading to repeated contamination, frequent cleaning, and an ongoing cycle of increasing fire risk. By capturing grease at the canopy, Ecofleece helps reduce contamination in the ductwork, lower the residual fuel load, and make maintenance more controlled. This preventative approach supports a consistently lower fire risk throughout the year, helping commercial kitchens improve safety, reduce disruption and protect both staff and premises.
Protecting the places you cannot easily reach IN COMMERCIAL KITCHENS
"Many of our venues are in Victorian buildings, with extraction systems hidden in basements, on rooftops or up to six storeys high, making them difficult to access and maintain. For us, Ecofleece Filters are about safety, helping to protect cleaned and TR19-certified systems by minimising grease build-up and safeguarding both new and ageing ventilation equipment."
Graeme Windsor, Kitchens Operations Manager, Signature Group

A Safer and More Sustainable Approach to Grease Management
Traditional metal baffle filters allow a significant proportion (up to 85%) of smaller grease particles to travel deeper into the kitchen extract system. Ecofleece adds a high-performance wool filtration layer that captures substantially more grease at canopy level.
By preventing more grease from reaching concealed areas, Ecofleece can help operators:
- Reduce grease accumulation inside ductwork.
- Lower grease-related fire exposure.
- Protect extract fans and downstream components.
- Maintain cleaner extraction systems.
- Reduce the frequency and intensity of grease-related cleaning.
- Support fire-risk, maintenance and ESG reporting objectives.
