Extract fan cleaning for kitchens and businesses in Isleworth
A fan never collects grease in a neat, even layer. Uneven build-up unbalances the impeller, which brings vibration, noise and extra wear on the bearings and motor. A thorough clean removes the cause. Typical jobs include burning smells from the fan area and grease around the motor and its mounts, across in-line fans, fan housings and discharge points.
Kitchens in Isleworth, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Between visits
Here’s the after-treatment advice, in brief:
- Leave a clear route to the fan
- Make sure the fan is included each time
- Run the extract throughout cooking
- Notice when the fan starts to sound different
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. A fan-only clean is recorded in the photo report.
The fan stays cleaner when less grease gets past the canopy. Keep the grease filters clean, fitted and in place, and replace any that are damaged.

Common questions in Isleworth
Can a school canteen extract in Isleworth be done out of term time?
Yes. The holidays are the usual time for school work. There are about 32 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Isleworth. Booking early in the term gives the best choice of holiday dates.
Can the work in Isleworth be done at night or at weekends?
Yes, we can come after you close and finish before you open. The work in Isleworth can fit around your hours. Just phone us on 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
Do you look at the system first?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where necessary. Then you get a fixed quote.
What happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
Does a TR19 kitchen extract clean cover the fan?
Yes, the fan is cleaned as part of TR19. If a fan can’t be reached, the report says so, so the record is accurate.
What should I send you?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then ring 0345 646 2711 or email us.
What’s the cleaning interval for an extract fan?
It’s cleaned with the whole extract, from every 3 months for 12 to 16 hours of cooking a day to every 12 months for 2 to 6 hours. Readings may show it needs cleaning more often.
Are you insured?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
Managing agents and facilities teams in Isleworth
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
Extract fan cleaning in Isleworth: the local picture
Food Standards Agency records include about 65 pubs, bars and clubs and about 13 hotels and B&Bs within about 1.5 miles of central Isleworth. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. In London, kitchens are normally cleaned overnight, when the kitchen is closed and loading is easier. Fire safety in Isleworth falls to London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
For kitchens close to Isleworth station, where the day often starts early and ends late, the extract can be cleaned overnight. If you run a church or community hall kitchen, near Church of All Saints or elsewhere in Isleworth, its extract still collects grease from every lunch and event. For schools such as St Mary's Catholic Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.

Why it’s worth doing now in Isleworth
Vibration from an unbalanced impeller does not stay small. It can wear the bearings and lead to failure and a kitchen can’t cook safely without extraction. A planned clean beats an emergency. Choosing the date yourself beats having a fault choose it for you.
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.

What happens on the day
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a couple of hours per fan, depending on its size and the build-up. Before any visit in Isleworth, we agree where the van can stop and how equipment reaches the system.
- Diagnosis first: we look for grease, noise and vibration.
- With the fan isolated, the housing is opened.
- Each blade is cleaned so the impeller runs evenly.
- Housing, outlet and the area around the motor are cleaned.
- The fan goes back into service with a report on its condition.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any parking or loading restrictions

What affects the cost of extract fan cleaning
There’s no set price list, because sites vary so much. What we look at:
- A single visit or a regular plan
- Any permits to work or inductions
- Parking and loading at the site
- The condition we find in the survey
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You will have a fixed price before any work starts.
Helping us quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Your opening hours and when the area is out of use
- Wide pictures of the system and the area around it
- Close-ups of filters, grilles, hatches or access panels
- How we’d reach plant on a roof or in a plant room
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and any previous report or certificate. Once you have those, give us a ring on 0345 646 2711, or email photos.
What staff can safely do
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
