Why Does Your Commercial Extractor Fan Need Cleaning?
Commercial kitchen extractor fans draw grease-laden air away from cooking equipment. Over time, grease can build up on fan blades, housings and surrounding extraction surfaces, restricting airflow, increasing strain on the fan and adding to the fire load within the system.
Grease Gone provides commercial extractor fan cleaning across London and the UK for restaurants, takeaways, hotels, canteens and other catering premises. Our extractor fan cleaners remove grease and carbon deposits from accessible fan components and can coordinate the work with kitchen duct cleaning where the wider extraction system also requires attention. Commercial kitchen grease-extract cleaning is carried out with reference to BESA TR19® Grease guidance.

Why Is Commercial Kitchen Extractor Fan Cleaning Important?
Grease build-up on extractor fan blades and housings can affect airflow, increase mechanical strain and contribute to fire risk within a commercial kitchen extraction system. Professional cleaning gives the fan and surrounding components dedicated attention that routine canopy and filter cleaning cannot provide.
What Is Included in Commercial Extractor Fan Cleaning?
The agreed scope depends on the fan type, access and condition of the wider extraction system. Services can include:
- Degreasing accessible extractor fan blades, impellers and housings
- Cleaning accessible fan casings, guards and surrounding extract surfaces
- Before-and-after inspection of the areas included in the agreed scope
- Coordination with canopy and ductwork cleaning where a full system clean is required
- Access-panel requirements identified where internal sections cannot otherwise be reached
Extractor Fan Cleaning vs Full Kitchen Extraction Cleaning
An extractor fan clean focuses on the fan assembly and accessible surrounding components. A full commercial kitchen extraction clean can extend from the canopy and filters through the ductwork to the fan and discharge point.
Where grease is present beyond the fan, we can coordinate the service with kitchen duct cleaning and canopy cleaning so the relevant extraction route is addressed. This distinction is important because cleaning only the visible fan does not remove deposits elsewhere in the grease-extract system.
Insurance reminder: Kitchen extract cleaning requirements can form part of an insurer’s fire-risk conditions. Check your policy and retain suitable cleaning records and reports.
How Often Should a Commercial Kitchen
Extractor Fan Be Cleaned?
Cleaning frequency should reflect kitchen operating hours, cooking methods, grease accumulation and the condition of the full extract system. BESA TR19® Grease guidance uses kitchen usage levels to establish minimum cleaning frequencies, with more frequent attention potentially required where grease loading is higher.
The table below provides a useful starting point for planning inspection and cleaning intervals. The fan should be considered as part of the wider grease-extract route rather than assessed in isolation.

J&I Grease Gone’s
Approach
Our commercial extractor fan cleaning service is planned around the type of system, access requirements and your kitchen operating hours. Before work begins, we agree the areas to be cleaned and whether the booking covers the fan only or a wider kitchen grease-extract clean. We can schedule work around food preparation and service times to help minimise disruption.

Grease Gone’s Cleaning Process
Our technicians first assess safe access to the extractor fan and the areas included in the agreed scope. Suitable components are degreased using specialist cleaning products and manual or mechanical methods appropriate to the system. The aim is to remove accessible grease and carbon deposits without presenting routine cleaning as mechanical repair or electrical servicing. If worn, damaged or inaccessible components are identified, these can be noted for follow-up.

Grease Gone post clean report
Following the clean, Grease Gone provides post-clean documentation for the work completed, including photographic evidence where applicable. For wider kitchen grease-extract cleaning, reporting can identify relevant system components and areas that were accessible during the service.
Where sections cannot be adequately reached, the report can highlight access limitations or recommendations for future cleaning. Any additional access work should be agreed separately before it is carried out.
How Our Extractor Fan Cleaning Service Works
We keep the booking process straightforward. Tell us about your kitchen, extractor fan and any wider extraction areas that may need attention, and we will agree the appropriate scope before the clean is scheduled.

Certification
On completion, Grease Gone provides documentation confirming the scope of the cleaning carried out. Where the service is completed as a TR19® Grease kitchen-extract clean, the reporting can be used as evidence of the work undertaken for your maintenance, fire-risk and insurance records. The exact documentation supplied depends on the agreed service scope.

Preparing for Commercial Extractor Fan Cleaning
Before the clean, we will confirm any access, shutdown or preparation requirements for your extractor fan and the wider extraction system. This may include making the relevant kitchen area accessible, protecting or removing food items and allowing equipment to cool where required.

Commercial Extractor Fan Cleaning FAQs
What is included in commercial extractor fan cleaning?
The scope depends on the fan type, access and condition of the system. Cleaning can include accessible fan blades or impellers, housings, casings, guards and surrounding extract surfaces. Where grease extends into the wider system, canopy and ductwork cleaning can be included as a separate or combined scope.
How often should a commercial kitchen extractor fan be cleaned?
Cleaning frequency depends on kitchen operating hours, cooking methods, grease loading and the condition of the extraction system. Higher-use kitchens may require more frequent inspection and cleaning, with TR19 Grease guidance used to help plan suitable intervals for the wider grease-extract system.
Is extractor fan cleaning the same as full kitchen extraction cleaning?
No. Extractor fan cleaning focuses on the fan assembly and accessible surrounding components. A full kitchen extraction clean can also cover the canopy, filters and ductwork through to the fan and discharge point. We can agree the correct scope before work begins.
Can extractor fan cleaning be completed outside kitchen operating hours?
Yes, subject to access and the requirements of the system. Grease Gone can arrange commercial extractor fan cleaning around food preparation and service times to help minimise disruption to your operation.
What documentation is provided after extractor fan cleaning?
Post-clean documentation is provided according to the agreed scope and can include photographic evidence and notes on accessible areas, limitations or recommendations. Where the work forms part of a TR19 Grease kitchen-extract clean, the reporting can support maintenance, fire-risk and insurance records.
