^{If you run a commercial kitchen, regular extraction cleaning isn’t optional—it’s essential for fire safety, compliance, and business protection.}

^{According to TR19 Grease guidelines, kitchen extract systems must be cleaned at specific intervals based on usage. But how often is your system supposed to be cleaned?}

^{In this guide, we break down the TR19 recommendations and explain exactly what your business needs to stay compliant.}

^{What Is TR19 Extraction Cleaning?}

^{TR19 is the UK’s leading standard for ventilation hygiene, developed to reduce fire risk caused by grease build-up in kitchen extraction systems.}

^{For restaurants, takeaways, pubs, and catering businesses, TR19 compliance helps ensure:}

^{•             Reduced fire risk}

^{•             Safe working conditions}

^{•             Compliance with insurance requirements}

^{•             Protection from enforcement action}

^{Without proper cleaning, grease can accumulate rapidly inside ductwork—creating a serious hazard.}

^{TR19 Cleaning Frequency Guidelines}

^{Cleaning frequency depends on how often your kitchen operates and the type of cooking you do.}

^{Recommended Cleaning Intervals:}

Kitchen Usage    Daily Hours         Cleaning Frequency

^{Heavy Use           12–16 hours       Every 3 months}

^{Moderate Use   6–12 hours          Every 6 months}

^{Light Use             2–6 hours            Every 12 months}

^{These are minimum guidelines—some kitchens may require more frequent cleaning depending on grease levels}

^{What Affects Cleaning Frequency?}

^{Not all kitchens are the same. TR19 emphasises a risk-based approach, meaning your cleaning schedule should reflect your actual usage.}

^{Factors include:}

• ^{Type of cooking (deep frying vs. light cooking)}
• ^{Volume of food production}
• ^{Length of operating hours}
• ^{Condition of ductwork and filters}
• ^{Previous grease build-up levels}

^{For example, a busy takeaway in Derby operating 14 hours a day will need far more frequent cleaning than a small café.}

^{Why Regular Extraction Cleaning Is Critical}

^{Fire Prevention}

^{Grease is highly flammable. Without regular cleaning, it can ignite and spread rapidly through duct systems.}

^{Insurance Compliance}

^{Most insurers require proof of TR19-compliant cleaning. Without certification, your policy could be invalid.}

^{Better Air Quality}

^{A clean system improves airflow, reduces heat, and creates a safer, more comfortable kitchen environment.}

^{System Efficiency}

^{Grease build-up restricts airflow and forces your system to work harder—leading to higher energy costs and potential breakdowns.}

^{Signs Your System Needs Cleaning Now}

^{Even if you’re on schedule, watch for these warning signs:}

• ^{Visible grease inside the canopy or ductwork}
• ^{Strong lingering cooking smells}
• ^{Poor airflow or excessive heat}
• ^{Grease dripping from filters}
• ^{Noisy or struggling extraction fan}

^{If you notice any of these, your system may already be above safe grease levels.}

^{What’s Included in a TR19 Extraction Clean?}

^{A professional TR19 clean goes far beyond surface cleaning. It includes:}

• ^{Canopy and filter degreasing}
• ^{Full ductwork cleaning}
• ^{Fan and motor cleaning}
• ^{Access panel inspection}
• ^{Before-and-after reporting}
• ^{TR19 certification}

^{The goal is to achieve a “bare metal clean”, removing all grease deposits from the system.}
