Keeping your commercial kitchen ducts and extractor fans cleaned isn’t just about hygiene — it’s about fire safety, legal compliance, efficiency, and protecting your business.
Here’s why it’s so important:
🔥 Fire Prevention (Biggest Reason)
◉ Cooking produces grease vapours that travel into the duct system. Over time, that grease:
◉ Sticks to duct walls
◉ Builds up inside fans
◉ Becomes highly flammable
If a flame or spark reaches that grease, it can spread rapidly through the ductwork and into the building structure.
⚠️ Many restaurant fires start in extraction systems.
◉ Regular cleaning removes this fuel source.
📜 Legal & Insurance Compliance
◉ Most countries require kitchen ventilation systems to be maintained under:
◉ Fire safety laws
◉ Health & safety regulations
◉ Insurance policy conditions
In the UK, systems are typically cleaned in line with TR19® guidelines (ventilation hygiene standards).
🦠 Hygiene & Pest Prevention
◉ Grease accumulation:
◉ Drips back onto cooking areas
◉ Creates odours
◉ Attracts pests
◉ Harbours bacteria
⏳ How Often Should It Be Done?
Depends on usage:
◉ Heavy use (fried food, 12+ hours daily): every 3 months
◉ Moderate use: every 6 months
◉ Light use: annually
