Extract fan cleaning for kitchens and businesses in Bushey
A fan never collects grease in a neat, even layer. Heavier deposits on some blades throw the impeller off balance, which brings vibration, noise and extra wear on the bearings and motor. A thorough clean removes the cause. Typical jobs include a fan that hums, whines or rumbles and vibration from an unbalanced impeller, across in-line fans, axial fans and fan housings.
In a town like Bushey, most of the kitchen extracts we are asked about belong to restaurants, cafés, pubs, takeaways and school or care home kitchens. Each has a canopy, filters, ductwork and a fan to keep clear of grease.
Each visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Report grease escaping from the fan
- Note any drop in extraction at the canopy
- Listen for new noises or vibration from the fan
- Keep access to the fan clear
The photo report shows the fan before and after cleaning. It notes what was done and anything that couldn’t be reached, along with the recommended next clean date.
Stick to the interval for the full extract. A fan cleaned with the rest of the system on time rarely gets badly coated, in line with BESA guidance.
Honest limits
We won’t sell you work that does not address the problem, so here are the limits:
- A fan that will not start
- An impeller that is bent or split
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
Not sure which it is? You can give us a ring on 0345 646 2711 or use the quote form and we’ll tell you honestly before booking.

The process
A visit follows the same order every time: protect the area, make the system safe, do the work, tidy up and leave you the report. The visit itself takes a couple of hours per fan, depending on its size and the build-up. A few photos of the system and its access points help us plan a visit in Bushey.
- First we check the fan’s condition and how it sounds.
- With the fan isolated, the housing is opened.
- The impeller is cleaned blade by blade so it runs balanced.
- We clean the casing, the outlet and around the motor.
- We run the fan and note its condition in the photo report.
Getting ready for the visit
- Arrange a key holder or contact on site
- Move anything stored near the system
- Have your last certificate or report to hand
Getting a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before work begins.

How the job changes from site to site
Kitchens with long cooking hours
When a busy kitchen’s fan fails, cooking stops. A clean fan is less likely to strain, and our 24/7 emergency callout is there if it happens anyway.
Inline duct fans
An inline fan can be easy to forget because it’s out of sight. We find it during the survey and include it in the clean.
Bushey questions
Do you clean school canteen extracts around Bushey out of term?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 18 schools, colleges and universities with registered kitchens within about a mile and a half of Bushey. Send us your term dates when you phone us on 0345 646 2711 or email us, and we’ll fit the work in.
Which environmental health team covers Bushey?
The local authority for Bushey is Hertsmere council, and its environmental health team does the inspecting. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
How much does extract fan cleaning cost?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before work begins.
What makes a kitchen extract fan vibrate?
Uneven grease on the impeller often causes it. We clean the fan and tell you if anything else, like worn bearings, is to blame.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
Can you come out in an emergency?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
Can the work be done while we’re closed?
Yes. Evenings, nights and weekends are normal working hours for us, so the site doesn’t lose a service.
Is TR19 cleaning required by law?
Not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005, which applies in England and Wales.
Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Bushey kitchens: local notes
The FSA’s data shows about 9 pubs and bars registered across Bushey and its immediate surroundings (about a mile and a half). Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Kitchens in Bushey get their food hygiene inspections from Hertsmere council. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Fire safety in Bushey falls to Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
School kitchens, at schools like Little Reddings Primary School for example, are normally cleaned in the holidays so no lunches are lost. If you run catering at a healthcare site, such as a hospital like Watford General Hospital about 2.1 miles west, the extract may need cleaning more often than a part-time kitchen.

Why act early in Bushey
Grease on the fan is grease in the system. A TR19 clean that left out the fan wouldn’t cover the whole system, and insurers asking for TR19 cleaning expect the full system. Whatever the system, dirt and wear only get worse.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before we start.

What we are called out for in Bushey
A fan collects more grease when the filters let more through. When filters don’t seal, grease goes straight through to the fan, so the fan takes far more than it should.
Look out for any of the following:
- Hot, greasy smells near the fan
- Fat spreading onto the roof or wall by the fan
- A fan that no longer moves enough air
- A fan that hums, whines or rumbles
A hall kitchen that only cooks for events, whether near Congregational Church or elsewhere in Bushey, still needs its extract cleaned, just less often.
