Why Insurance Companies Require Kitchen Extract Cleaning
Commercial kitchens work hard every day, producing heat, smoke, grease and cooking vapours that are safely removed through the kitchen extraction system. While most operators understand the importance of cleaning visible surfaces, it’s easy to overlook what happens inside the canopy, ductwork and extraction fan. Over time, grease accumulates throughout the entire extraction system. This build-up is one of the most common fire hazards in commercial kitchens, which is why many insurers expect businesses to maintain their extraction systems and keep records of professional cleaning. Whether you operate a restaurant, hotel, café, pub, school kitchen or healthcare facility, regular kitchen extract cleaning is an essential part of protecting your staff, customers and business. Why Is Grease Such a Fire Risk? Every time food is cooked, tiny grease particles become airborne. As they pass through the extraction system, they stick to: Kitchen canopies Grease filters Horizontal ductwork Vertical ductwork Extraction fans Ventilation components Over weeks and months, these deposits become thicker and increasingly flammable. If a cooking flare-up reaches contaminated ductwork, the fire can spread rapidly through the extraction system, potentially affecting other parts of the building. Professional cleaning removes this hidden fuel before it becomes a serious risk. Why Do Insurance Companies Care? From an insurer’s perspective, commercial kitchen fires can result in: Significant property damage Business interruption Lost revenue Damage to neighbouring properties Expensive claims Regular maintenance helps reduce these risks. Insurers may ask for evidence that extraction systems have been professionally cleaned and maintained as part of a sensible fire prevention programme. Keeping accurate maintenance records demonstrates that you’ve taken reasonable steps to manage a known risk. The Parts You Can’t See Matter Most Many kitchens clean the visible canopy every day, but the hidden parts of the system often receive far less attention. Professional extraction cleaning covers much more than the canopy itself, including: Internal ductwork Vertical risers Roof-mounted fans Grease collection points Access panels Filters and associated components The greatest fire risk is often found inside these hidden areas rather than on the visible stainless-steel surfaces. How Often Should Kitchen Extraction Systems Be Cleaned? The ideal cleaning frequency depends on how heavily the kitchen is used. Kitchen Usage Typical Cleaning Frequency Heavy use (12–16 hours/day) Every 3 months Moderate use (6–12 hours/day) Every 6 months Light use (2–6 hours/day) Every 12 months Examples include: Restaurants Hotels Pubs Cafés Schools Hospitals Nursing homes Food production facilities A professional inspection can help determine the most appropriate maintenance schedule for your premises. More Than Fire Protection Regular kitchen extract cleaning also delivers a number of operational benefits. Improved Ventilation Grease restricts airflow, making extraction systems less effective. Cleaning restores airflow and helps remove: Heat Smoke Steam Cooking odours This creates a more comfortable working environment for kitchen staff. Improved Energy Efficiency Blocked ductwork forces extraction fans to work harder. A clean system typically: Uses less energy Places less strain on motors Reduces wear on equipment Helps extend system life Reduced Equipment Downtime Grease contamination contributes to mechanical wear and unexpected breakdowns. Preventative maintenance helps identify issues before they become expensive repairs. Documentation Matters Professional contractors don’t simply clean the system—they provide evidence that the work has been completed. This often includes: Before-and-after photographs Cleaning reports Maintenance certificates Recommendations for future cleaning Details of any areas requiring attention These records can be valuable for insurance purposes, fire safety management and planned maintenance programmes. Choosing a Professional Kitchen Extract Cleaning Company When selecting a contractor, look for a company that can: Clean the complete extraction system—not just the canopy Access difficult ductwork safely Provide detailed photographic reports Work around your operating hours Deliver clear maintenance documentation Recommend an ongoing cleaning schedule A thorough service should leave the entire extraction system cleaner, safer and operating more efficiently.

Frequently Asked Questions Does cleaning the canopy alone reduce the fire risk? No. While daily canopy cleaning is important, grease also accumulates inside the ductwork and extraction fan. These hidden areas should be professionally cleaned as part of a complete system. Can dirty extraction systems affect ventilation? Yes. Grease build-up restricts airflow, making extraction systems less effective at removing heat, smoke and cooking vapours. How long does professional kitchen extract cleaning take? The duration depends on the size and condition of the system. Smaller café systems may take a few hours, while larger commercial kitchens or hotels may require a full day or more. Will the kitchen need to close? Most professional cleaning can be scheduled outside normal operating hours to minimise disruption.
