✅ Increased fire risk due to grease accumulation
✅ Failed hygiene inspections that could shut down your business
✅ Poor kitchen air quality leading to uncomfortable conditions
✅ Higher energy costs due to inefficient ventilation

1. The Dangers of a Dirty Kitchen Extraction System
If you don’t clean your kitchen extraction system regularly, grease, dust, and carbon deposits will build up in the ductwork, fans, and filters. This can lead to severe risks:
🔥 Fire Hazards
Grease buildup is highly flammable. If high heat or an electrical fault ignites the grease, it can spread fire rapidly through the duct system. According to UK fire safety reports:
🚨 Over 70% of restaurant fires are caused by grease and fat buildup in extraction systems.
🚨 Fire spreads 6x faster in grease-coated ducts.
🚨 Non-compliance with cleaning regulations can void insurance claims in the event of a fire.
💡 Preventative Action:
✔ Schedule TR19-compliant deep cleans at least every 3-12 months.
✔ Regularly change grease filters to prevent buildup.
🦠 Health & Hygiene Risks
A dirty extraction system traps bacteria, mould, and airborne contaminants, which can lead to:
- Poor air quality in the kitchen
- Increased risk of food contamination
- Staff exposure to toxic airborne particles
- Unpleasant odours spreading into dining areas
📌 Health & Safety Compliance:
✔ Under COSHH regulations, businesses must control airborne contaminants in workplaces.
✔ TR19 standards ensure safe ventilation in commercial kitchens.
⚠️ Legal Consequences & Fines
In the UK, failure to comply with TR19 grease cleaning regulations can lead to:
- Hygiene inspection failures
- Fines & legal action under the Fire Safety Order 2005
- Temporary or permanent closure of the business

2. TR19 Grease Cleaning Guidelines: How Often Should You Clean?
The TR19 standard, set by the Building Engineering Services Association (BESA), outlines how frequently kitchen extraction systems must be cleaned based on kitchen usage:
| Kitchen Usage (Hours per Day) | Cleaning Frequency Required |
|---|---|
| 12+ hours per day | Every 3 months |
| 6-12 hours per day | Every 6 months |
| 2-6 hours per day | Every 12 months |
📌 Important: If you don’t follow these frequencies, you risk failing inspections and voiding insurance policies.

3. The Benefits of Regular Kitchen Extraction Cleaning
Investing in professional extraction cleaning protects your business, staff, and customers. Here’s how:
✅ Fire Safety Compliance
Regular cleaning removes flammable grease, drastically reducing the risk of a catastrophic kitchen fire.
✅ Legal & Insurance Compliance
Keeping your kitchen extraction system TR19-compliant ensures your insurance remains valid and prevents legal fines.
✅ Better Air Quality & Kitchen Conditions
A clean extraction system:
✔ Prevents unpleasant odours from grease buildup
✔ Reduces moisture & bacteria growth
✔ Improves ventilation & airflow
✅ Energy Efficiency & Lower Costs
Blocked filters and ducts make extraction fans work harder, increasing energy consumption. Keeping them clean improves efficiency and lowers electricity costs.
