Fire Safety Requirements for Restaurant Kitchens

Every Six Days, a UK Restaurant Burns

That's the sobering statistic from the Home Office fire data: commercial kitchens account for hundreds of fires annually in England alone. Curry restaurants face particular risks — tandoor ovens reaching 480°C, deep fat fryers bubbling with oil, open gas flames, and extraction systems clogged with grease all create a perfect storm of fire hazards. Yet when we visit restaurants across the country, fire safety is consistently the area where compliance falls shortest. It's not glamorous, it's not exciting, and it doesn't make anyone money — but it keeps people alive and your business open.

Under the Regulatory Reform (Fire Safety) Order 2005, every business premises in England and Wales must have a fire risk assessment carried out by a "responsible person" — that's you, the business owner, or a competent person you designate. This isn't a suggestion; it's a legal requirement, and failure to comply can result in unlimited fines or imprisonment in the most serious cases.

The Fire Risk Assessment

Your fire risk assessment must identify potential fire hazards, determine who's at risk, evaluate the risks and decide on precautions, record your findings and implement them, and review the assessment regularly. For a curry restaurant kitchen, the key hazards include:

• Cooking oils and fats — The number one cause of kitchen fires. Oil can auto-ignite at around 340°C, and a deep fat fryer or karahi of hot oil that's left unattended or overheated can go from cooking to conflagration in minutes.
• Tandoor ovens — These operate at extreme temperatures and radiate intense heat. Combustible materials stored too close to a tandoor are a common finding in fire inspections.
• Gas appliances — Gas leaks, faulty connections, and improper installations cause a significant proportion of restaurant fires. Annual gas safety checks by a Gas Safe registered engineer are a legal requirement.
• Extraction and ventilation systems — Grease builds up in extraction hoods and ductwork over time. This grease is highly flammable, and a fire that reaches the extraction system can spread rapidly through the entire building.
• Electrical equipment — Overloaded sockets, damaged cables, and appliances used beyond their service life are common electrical fire risks in busy kitchens.

You can carry out a fire risk assessment yourself using the government's free guides, but for a restaurant kitchen with its specific hazards, we'd strongly recommend engaging a professional fire risk assessor. Expect to pay £200-500 for a thorough assessment of a typical restaurant premises.

Fire Extinguishers: Getting the Right Ones

Not all fire extinguishers are created equal, and using the wrong type on a kitchen fire can make things dramatically worse. Here's what you need:

1. Wet chemical extinguisher (yellow band) — Essential for cooking oil and fat fires. This is the only extinguisher type rated for Class F fires (cooking oils). Every commercial kitchen must have at least one, positioned near the cooking area but not so close that a fire would prevent you reaching it. Two to three metres away from the main cooking station is ideal.
2. CO2 extinguisher (black band) — For electrical fires. Keep one near your electrical distribution board and any areas with significant electrical equipment.
3. Water or foam extinguisher (red or cream band) — For general combustibles like paper, wood, and textiles. Useful for dining areas, storage rooms, and offices.

All extinguishers must be serviced annually by a competent person and inspected monthly by a member of staff (simply checking the pressure gauge and that the pin is intact). Keep records of all inspections.

Fire Blankets and Suppression Systems

Fire blankets should be positioned within easy reach of every cooking station. They're invaluable for smothering small pan fires before they escalate. Ensure every member of kitchen staff knows where the blankets are and how to deploy them correctly — pulled outward, not upward, and placed gently over the fire rather than thrown.

For tandoors and deep fat fryers, consider installing an automatic fire suppression system (such as Ansul or Amerex). These systems detect heat above a threshold and automatically discharge wet chemical agent directly onto the fire source. They're not cheap — £2,000-5,000 installed — but they're extraordinarily effective and may reduce your insurance premiums significantly. Some insurers now mandate them for restaurants with deep fat fryers.

Staff Training and Fire Drills

Every member of staff should receive fire safety training that covers: how to raise the alarm, evacuation procedures and assembly points, location and use of fire extinguishers and blankets, how to call the fire service, and specific kitchen fire procedures (never move a burning pan, never throw water on an oil fire). Train new staff on their first day, and run refresher training at least annually. Conduct fire drills twice a year and document them.

Fire Exits, Doors, and Maintenance

Fire exits must be clearly signed, illuminated, and unobstructed at all times. We see restaurants using fire exits as extra storage space disturbingly often — this is an immediate enforcement notice waiting to happen. Fire doors must be self-closing and never propped open during service (use magnetic hold-open devices connected to the fire alarm if you need them open routinely).

Ensure your fire alarm system is tested weekly (press a different call point each week) and professionally serviced every six months. Emergency lighting must be tested monthly and receive a full discharge test annually.

Insurance Implications

Your insurance policy will almost certainly have fire safety conditions. Failing to meet them could void your cover entirely — meaning if you do have a fire, you'll receive nothing. Common conditions include maintaining extinguishers, cleaning extraction systems quarterly, holding a valid fire risk assessment, and having gas appliances checked annually. Check your policy and comply meticulously.
