How Often Should Extraction Systems Be Cleaned?
5 min read
What is TR19?
TR19 is the industry standard for the cleanliness of ventilation systems published by the Building Engineering Services Association (BESA). It sets out the requirements for the inspection, testing, and cleaning of grease extract systems in commercial kitchens.
Why Does TR19 Matter?
Insurance companies increasingly require TR19 compliance as a condition of cover. If a fire breaks out in your kitchen extraction system and you can't provide evidence of regular cleaning to TR19 standards, your insurer may refuse your claim.
Local authorities and fire safety officers also reference TR19 during inspections. Non-compliance can result in enforcement notices, fines, or even closure orders.
How Often Should Systems Be Cleaned?
TR19 recommends cleaning frequencies based on usage:
- Heavy use (24-hour operations, fast food): Every 3 months
- Moderate use (restaurants, hotels): Every 6 months
- Light use (cafes, care homes): Every 12 months
Your cleaning provider should assess your system and recommend an appropriate schedule.
What Should a TR19 Clean Include?
A compliant TR19 clean covers the entire extraction system from the canopy filters through the ductwork to the fan on the roof. The process includes pre-clean inspection, removal and cleaning of grease filters, internal duct cleaning using specialist equipment, fan cleaning and inspection, and a post-clean report with photographic evidence.
Choosing a TR19 Certified Cleaner
Always use a cleaner who is TR19 certified and can provide proper documentation. CKC Approved cleaners are all verified for TR19 compliance and will provide you with the certificates and reports you need for your insurance and fire safety records.
