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, cafĂ©, 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 CafĂ©s 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.

We work with restaurants, cafĂ©s, hotels, healthcare facilities, schools, industrial kitchens and food production businesses, delivering flexible maintenance programmes designed around your operational requirements. 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 cafĂ© 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.

7 Signs You Need Professional Air Duct Cleaning

Your building’s ventilation system works quietly in the background every day, circulating fresh air throughout offices, hospitals, retail premises, schools and industrial facilities. Because most of the ductwork is hidden above ceilings or behind walls, it’s easy to forget it even exists. Unfortunately, dust, dirt, construction debris, pollen and other contaminants gradually build up inside air ducts. Over time this can restrict airflow, reduce energy efficiency and negatively affect indoor air quality. Professional air duct cleaning helps restore your ventilation system to peak performance while supporting healthier, safer workplaces. At VSS Ireland, our experienced technicians carry out ductwork cleaning using specialist equipment and provide detailed reports with photographic evidence and certification on completion. 1. Your Energy Bills Keep Increasing One of the earliest warning signs is an unexplained increase in electricity costs. When ductwork becomes contaminated, fans and air handling units must work harder to move air around the building. This increased workload means: Higher electricity consumption Reduced system efficiency Increased wear on equipment Regular duct cleaning helps maintain efficient airflow and reduces unnecessary strain on your HVAC system. 2. Poor Airflow Around the Building If some rooms always feel stuffy while others seem over-ventilated, restricted ductwork could be the cause. Signs include: Weak airflow from vents Hot and cold spots Meeting rooms feeling uncomfortable Staff constantly adjusting thermostats These symptoms often indicate it’s time for a professional inspection. 3. Dust Quickly Returns After Cleaning If your cleaning team regularly dusts surfaces but they become dusty again within days, your ventilation system could be redistributing contaminants throughout the building. Dirty ductwork may circulate: Dust Fibres Construction debris General airborne particles Professional cleaning removes these contaminants at their source. 4. Unpleasant Smells Coming from Air Vents Persistent musty or stale odours are another common warning sign. Possible causes include: Dust build-up Damp areas within ductwork Organic contamination Poor ventilation Cleaning and sanitising the ductwork can help eliminate these odours and improve indoor air quality. 5. Staff Complaints About Air Quality Facility managers often hear comments such as: “The office feels stuffy.” “The air feels dusty.” “The meeting rooms get uncomfortable.” While there can be several causes, contaminated ventilation systems are frequently part of the problem. Improving ventilation hygiene contributes to a healthier, more comfortable working environment. 6. Your Building Has Recently Been Renovated Construction projects generate huge amounts of fine dust. Even with protective measures, debris often finds its way into ventilation systems. If your premises has recently undergone: Office refurbishment Shop fit-out Building extension Mechanical upgrades it’s worth arranging a duct inspection before returning the system to normal operation. 7. It’s Been Years Since Your Last Inspection Many commercial buildings simply don’t have a maintenance history for their ductwork. If you don’t know when your ducts were last inspected or cleaned, it’s probably time to arrange a professional survey.

What is Preferred Vacuum Testing (PVT)?

The industry standard approach is to assess air quality through measuring various parameters, including: particulate matter chemical pollutants microbial contaminants. Preferred Vacuum testing or negative pressure testing, may be used in certain situations to evaluate the performance of ventilation systems and the overall air hygiene. Here are some reasons why vacuum testing is important for air hygiene reporting: Ductwork Integrity: Vacuum testing can be used to assess the integrity of ductwork in ventilation systems. It helps identify leaks, gaps, or other issues that could compromise the efficiency of the system and contribute to the spread of contaminants. Airflow Measurement: Vacuum testing allows for the measurement of airflow rates within a ventilation system. Proper airflow is crucial for maintaining air quality and ensuring that contaminants are effectively removed. Containment Assessment: In environments where airborne contaminants need to be controlled (such as in laboratories, cleanrooms, or healthcare facilities), vacuum testing helps evaluate the effectiveness of containment systems, such as fume hoods or isolation rooms. Pressure Differentials: Maintaining appropriate pressure differentials between different zones is critical for preventing the spread of contaminants. Vacuum testing can be used to measure and ensure proper pressure differentials are maintained. Regulatory Compliance: Many industries and facilities are subject to regulations and standards related to air quality. Vacuum testing may be preferred to ensure compliance with specific air hygiene standards and guidelines. Health and Safety: Assessing air quality through vacuum testing contributes to creating a healthier and safer indoor environment. It helps identify potential issues that could affect the well-being of occupants. Performance Verification: Vacuum testing serves as a method for verifying the performance of ventilation systems, ensuring that they meet the designed specifications and effectively control indoor air quality. It is a legal requirement for the building owner or occupier to ensure air handling units are kept clean and contaminant-free, and in many cases, Air Hygiene tests have uncovered serious potential hazards which our clients were then able to address on their premises. Using Preferred Vacuum Tests (PVT)  or Microbiological Swab Tests we can assess the air quality passing through the ventilation system. Tests are taken on-site by appointment and sent to our laboratory for testing. A detailed report is provided to measure the Air Quality against 3 different SQC Ratings: Hospitals Labs Schools Restaurants Warehouses Depending on the levels of contamination found, the ventilation system is given a pass or fail rating. The results of this testing are then issued in a report to the client with our recommendations for the next steps if required. All VSS Ireland site works are overseen by our experienced contract management team and service delivery department.
