Commercial Kitchen Fire Suppression Systems

Commercial kitchens present a high fire risk due to cooking oils, fats, open flames, high temperatures and grease-laden extract systems. A properly designed kitchen fire suppression system helps protect cooking equipment, extract canopies, ductwork and staff by responding rapidly to fire in critical kitchen areas. In the UK, fire safety duties for workplaces are governed by the Regulatory Reform (Fire Safety) Order 2005, and BAFE recommends using appropriately third-party certificated providers for kitchen fire protection systems. We work with the Defender kitchen fire suppression system by Finder, a specialist system developed for the protection of commercial catering equipment. 

 

What is a kitchen fire suppression system?

A kitchen fire suppression system is a fixed fire protection system designed for commercial cooking equipment where cooking oils or fats are present. FIA guidance describes kitchen fire extinguishing systems as fixed systems intended to protect catering equipment and related extract systems and filters. These systems are used in commercial kitchens where rapid suppression and shutdown of hazards are critical. A properly designed system can help protect hazardous cooking appliances, canopies, plenum areas, extract duct connections and associated cooking risks.

Why commercial kitchens need specialist fire protection

Commercial kitchens are exposed to elevated fire risk because of naked flames, hot oils, grease build-up and continuous cooking operations. London Fire Brigade states that businesses have a legal duty under the Fire Safety Order to safeguard staff, customers and the public, and gives specific fire safety advice for takeaways, cafés and restaurants. FIA guidance also highlights the importance of managing Class F fires, which involve cooking oils and fats and require specialised handling.

A kitchen fire suppression system is especially important where:

  • deep fat frying is present

  • high-output cooking equipment is used

  • extract systems carry grease-laden vapours

  • the kitchen operates for long hours

  • business continuity is important

  • insurers, landlords or fire risk assessors require enhanced protection

Our Services

Design and system selection

We assess the kitchen layout, protected appliances and operational risks to determine the appropriate suppression arrangement and system for the site.

Installation

We install the system in line with the equipment layout and project requirements, coordinating with kitchen operators and other trades where needed.

Commissioning

Once installed, the system is commissioned and checked to confirm correct operation and interface performance.

Servicing and maintenance

BAFE notes that once a kitchen fire protection system is installed, it is a legal requirement to ensure it is maintained appropriately so it remains ready to activate in the event of a fire.

System upgrades and replacements

We can also review older kitchen fire suppression systems and advise on upgrades, replacement or reconfiguration where kitchen equipment has changed.

System interfacing and shutdowns

Kitchen fire suppression systems often need to interface with other building and kitchen services. FIA guidance notes that commercial kitchen fire protection may need to integrate with systems such as extract fans, building management systems and fuel supplies, which often need to be shut off in the event of a fire.

Depending on project requirements, this may include:

  • gas shut-off

  • electrical isolation

  • extract or supply fan interface

  • local alarm or control integration

Maintenance matters

A suppression system is only valuable if it is ready to operate when needed. BAFE states that installed kitchen fire suppression systems must be maintained appropriately. That makes routine servicing an essential part of compliance and risk control, not an optional extra.

Regular maintenance helps support:

  • operational readiness

  • continued compliance

  • insurer confidence

  • reduced downtime risk

  • protection of staff and premises

  • suitable system selection
  • clear scope of protection
  • proper installation
  • coordinated shutdown interfaces
  • reliable servicing support

Frequently asked question

Do commercial kitchens need a fire suppression system?

The exact requirement depends on the premises, equipment, fire risk assessment, insurer expectations and local enforcement context. Under the Fire Safety Order, the responsible person must assess fire risks and provide suitable fire precautions. London Fire Brigade and BAFE both emphasise the importance of proper kitchen fire protection in commercial settings.

What does a kitchen suppression system protect?

FIA guidance says kitchen fire extinguishing systems are designed to protect catering equipment where cooking oils or fats are present, along with related extract systems and filters.

Do these systems need servicing?

Yes. BAFE states that once installed, the system must be maintained appropriately so it remains ready to activate.

Can the system shut down gas or fans?

It can be designed to interface with fuel supplies, fans and other systems where required. FIA specifically notes that these interfaces are often part of commercial kitchen fire protection.
