UK Fire Safety Order Guidance for Commercial Kitchens

A commercial kitchen can move from normal service to a serious fire within seconds. Hot oil, open flame, fat-laden extract, high electrical loads and busy working conditions make it one of the highest-risk areas in most premises. This UK fire safety order guidance explains what dutyholders need to do, where kitchen risks demand extra control, and why a generic approach is rarely enough.

For most businesses in England and Wales, the core legislation is the Regulatory Reform (Fire Safety) Order 2005. It places responsibility on the person who controls the premises or business activity to manage fire safety properly. That responsibility cannot be passed to a contractor, landlord or fire risk assessor simply by appointing them. Professional support is valuable, but the responsible person remains accountable.

What the Fire Safety Order Requires

The Order requires the responsible person to take general fire precautions that are reasonable in the circumstances. In practical terms, this means identifying hazards, assessing who could be harmed, putting suitable measures in place and keeping those measures under review.

The duty usually sits with the employer, building owner, occupier, managing agent or another person with control of the premises. In a restaurant or hospitality venue, there may be more than one responsible person. For example, a landlord may control shared escape routes while the operator controls the kitchen, staff procedures and equipment. Responsibilities should be clear rather than assumed.

A suitable and sufficient fire risk assessment is the starting point. It must consider the premises as they operate in reality, not as they appear on a quiet inspection day. A kitchen running a full Friday-night service presents different risks from one operating only light daytime catering.

Where five or more people are employed, the significant findings of the fire risk assessment and the measures taken must be recorded. Even where formal recording is not required, a written record is sensible. It creates a clear basis for training, maintenance, review and enforcement discussions.

UK Fire Safety Order Guidance for Kitchen Risks

A fire risk assessment should identify ignition sources, fuel sources and people at risk, then examine how a fire could start and spread. Commercial kitchens often bring all three together in a compact space.

Deep-fat fryers, ranges, chargrills, woks and solid-fuel appliances can produce intense heat and cooking oil fires that cannot be safely tackled with water. Grease deposits within extract canopies and ductwork can act as a fuel path, allowing fire to travel beyond the cooking line. Electrical appliances, overloaded circuits, damaged cables and poorly maintained gas equipment add further ignition risks.

The assessment should also account for people who may not know the building well, work alone, have reduced mobility or be exposed to risk while sleeping. In hotels, care settings, venues with staff accommodation and late-night operations, a kitchen fire may affect people far beyond the kitchen team.

The right controls depend on the cooking equipment, the extract arrangement, building layout, occupancy and insurer requirements. However, most commercial kitchens need a combination of effective extraction cleaning, planned equipment maintenance, staff training, suitable portable extinguishers and fire blankets, clear escape routes, detection and alarm arrangements, and a fixed suppression system where the hazard justifies it.

A fixed kitchen fire suppression system is designed to detect fire in the cooking area and discharge a wet chemical agent over the hazard. Correctly designed systems also shut down fuel or electrical supplies and can interface with other fire safety systems. This matters because controlling the source of heat is central to preventing re-ignition after initial knockdown.

Suppression is not a replacement for good housekeeping, extraction cleaning or staff competence. It is a critical additional layer of protection for high-risk cooking equipment, particularly where a fire could develop quickly outside normal hours or where the consequences of closure would be significant.

Treat the extract system as part of the fire risk

The canopy and ductwork are sometimes overlooked because they sit above or beyond the visible cooking line. Yet grease build-up can materially increase fire spread risk. The frequency of specialist extract cleaning should reflect the volume and type of cooking, not a calendar date chosen for convenience.

Cleaning records, access provision and post-clean inspections should all support the risk assessment. If the cooking line is changed, expanded or moved, the extract system and suppression coverage should be reviewed at the same time.

Make sure protection matches the equipment

Adding a new fryer, changing a range for a chargrill or repositioning appliances can leave nozzles, detection components or manual activation points in the wrong place. A system that was suitable at installation can become unsuitable after a kitchen refit.

This is where specialist design matters. The system must be approved for the specific hazard, installed to the manufacturer’s requirements and interfaced correctly with gas, electric and ventilation shut-off arrangements. A certificate alone does not prove ongoing suitability if the kitchen has changed.

From Risk Assessment to Day-to-Day Control

A fire risk assessment only works when its findings become normal operating practice. Managers should be able to show how staff are trained, how faults are reported and how emergency procedures are followed during a live service.

Kitchen staff need practical instruction that reflects the equipment they use. They should know the location of manual suppression activation, the alarm procedure, when it is safe to attempt first-aid firefighting, and when to leave immediately. No member of staff should be expected to tackle a developed oil fire or delay evacuation to protect stock or equipment.

Fire doors must close and latch properly, escape routes must remain clear, and combustible packaging must not accumulate near cooking equipment or electrical panels. These may sound basic, but they are frequent causes of avoidable enforcement action and can undermine otherwise well-managed premises.

Testing and maintenance must also be planned, recorded and completed by competent providers. This covers alarm systems, emergency lighting, extinguishers, fire doors, gas safety arrangements and kitchen suppression equipment. For suppression systems, maintenance intervals and service procedures should follow the system manufacturer’s requirements. A missed service can affect reliability, warranty status and insurer confidence.

Review the Assessment When the Kitchen Changes

Fire risk assessment is not a one-off document. It should be reviewed regularly and whenever there is reason to believe it is no longer valid. In commercial kitchens, that trigger often arrives sooner than expected.

A review is needed after a fire, near miss, significant maintenance issue, equipment change, refurbishment, change in occupancy, alteration to opening hours or shift in the type of cooking undertaken. Changes in staffing can matter too. A smaller late-night team may have different evacuation and emergency response capability from a fully staffed daytime operation.

Insurer surveys should be treated as useful evidence, not as a separate compliance exercise. Insurers may require certified suppression, specific extraction-cleaning frequencies or improvements to shut-off interfaces because they understand the loss potential of kitchen fires. Addressing those requirements promptly protects cover as well as the premises.

The Position Across the UK

The Regulatory Reform (Fire Safety) Order 2005 applies in England and Wales. The underlying principles in this guidance are relevant across Great Britain, but the legal framework differs elsewhere. Scotland operates under separate fire safety legislation, while Northern Ireland has its own fire safety regime.

For organisations operating at multiple sites, a consistent fire safety standard is sensible, but legal references, enforcement arrangements and documentation should be checked for each jurisdiction. A national operator should not assume that one assessment template or policy automatically meets every local requirement.

Practical Questions for Responsible Persons

Before accepting that kitchen fire safety is under control, ask whether the fire risk assessment specifically addresses cooking risks, grease-laden extract and likely fire spread. Check whether the installed suppression system protects every current appliance, isolates fuel or power where required, and has been maintained by a competent specialist.

Also consider the operational test: could a new member of staff explain what to do if a fryer ignites during service? Could the kitchen evacuate without passing through smoke or blocked routes? Are maintenance records available and current? If the answer is uncertain, the control measure is not yet dependable.

Kitchen Fire Suppression Systems Ltd works solely with commercial kitchen suppression, from system design and installation through to interfaces and planned maintenance. That specialist focus helps operators ensure their protection remains aligned with the cooking risk, rather than becoming an overlooked item above the canopy.

The most useful outcome of a fire risk assessment is not a folder on a shelf. It is a kitchen where the hazards are understood, protection works when it is needed, and staff can get out safely while the business has the best possible chance of reopening quickly.
