Grease builds up inside every commercial kitchen extract system, and once it lines the canopy, ductwork and fan it becomes a serious fire and hygiene risk. We deep clean and maintain kitchen extraction ducts, canopies and ventilation systems to the BESA TR19 Grease standard, and document every job so you and your insurer can see the system is compliant.
Kitchen extractors draw grease, hot air and odours away from cooking areas. With use, layers of fat and oil build up on the inside of the metalwork. When exposed to high temperatures and naked flames, those deposits can ignite, and a fire spreads quickly. The same build-up also causes unpleasant smells, contaminated air flowing back into the kitchen, and pest infestation.
Regular assessment and thorough cleaning reduce these risks and keep your ductwork compliant with the BESA TR19 Grease specification. As a BESCA Vent Hygiene Associate member, we clean back to the bare metal and certify the result, so your kitchen extract system meets current fire-safety expectations.
Failure to keep the system clean can invalidate your insurance policy in the event of a fire, which is why every clean we carry out is fully documented and certified.
Our service focuses on cleaning and maintaining the whole kitchen extract ventilation system. That includes:
- Hood and canopy cleaning — removing grease, grime and flammable residues that accumulate during cooking.
- Ductwork cleaning — clearing grease build-up along the full extract ductwork to reduce fire risk and restore airflow.
- Fan cleaning — cleaning and degreasing extract fans for efficient, safe operation.
- Access panel installation — fitting access panels so ductwork can be inspected and cleaned in future.
- Grease filter replacement — cleaning or replacing grease filters to maintain effective filtration.
- TR19 Grease compliance — cleaning to BESA’s TR19 Grease standard for kitchen extract systems.
- Certification and documentation — a full written report with before-and-after photos after every visit.
- Access cleaning — cleaning and sanitising hard-to-reach areas within the system for a comprehensive result.
- Frequency planning — a cleaning schedule matched to how hard your kitchen is used.
- Risk assessment — identifying fire hazards and areas of concern across the extract system.
Recommended cleaning frequency
TR19 Grease sets cleaning frequency by how many hours the kitchen runs each day. As a guide:
| Usage | Daily use | Cleaning frequency |
|---|
| Light | 2–6 hours per day | 12-monthly |
| Moderate | 6–12 hours per day | 6-monthly |
| Heavy | 12–16 hours per day | 3-monthly |
We confirm the right interval for your kitchen at the survey stage.
- Fire prevention — regular cleaning reduces the risk of kitchen fires caused by grease build-up in the extract system.
- Health, safety and insurance compliance — meets the standards expected of commercial kitchens and keeps your fire-insurance cover valid.
- Improved air quality — removes grease, odours and contaminants from the ventilation system.
- Energy efficiency — a clean, well-maintained system runs more efficiently.
- Extended equipment life — regular cleaning helps extend the lifespan of extract components and reduces replacements.
- Enhanced kitchen hygiene — prevents the growth of bacteria and mould inside the extract system.
- Reduced operational risk — minimises breakdowns and costly disruption from a neglected system.
- Lower maintenance costs — prevents excessive wear and tear, cutting the frequency of repairs.
- Odour control — clears the grease and debris that cause unpleasant smells in kitchen and dining areas.
What we do
- Inspect and risk assess the kitchen extraction system.
- Deep clean and remove all grease, right back to the metal on canopies and ductwork.
- Use only environmentally friendly chemicals that are safe on metalwork and fire-safety coatings.
- Produce TR19 Grease certification of compliance, required for insurance validity, on completion.
- Consult with you to create an ongoing cleaning and maintenance plan.
- Provide out-of-hours cleaning so we can work around your service times.
Book a TR19 Grease survey of your kitchen extract system and we will assess the grease build-up, agree the right cleaning frequency, and certify the work once it is done.
