Extract Fan Cleaning in Broadfields Estate

Extract fan cleaning in Broadfields Estate, done properly
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. Cleaning the impeller and housing puts that right. We are often asked to deal with a fan motor running hot under a coat of grease and grease escaping from the fan outlet, across centrifugal fans, in-line fans and axial fans.
London kitchens tend to trade late and open early, so work in Broadfields Estate is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
The paperwork matters as much as the work. You get a written report with pictures after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

What happens if it’s left?
Grease on a roof fan can also escape outside. It marks the area around the outlet and leaves more fuel outside, which is one more reason to keep it clean. Planning ahead in Broadfields Estate lets you pick a quiet night rather than lose a busy one.
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and why the quote is fixed before work begins.

How the visit works
Each visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the extract fan cleaning, tidy up and leave you the report. On site, the work takes a few hours where there are several fans or heavy deposits. Getting kit into a London building takes planning, so let us know where we can load and park in Broadfields Estate.
- We start by checking where the fan sits and how to isolate it.
- Power to the fan is isolated before anyone touches it.
- Grease is scraped from the impeller blades and the inside of the housing.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- It’s closed up, run and checked, and pictures go into your report.
Before we arrive
- Tell us where we can park and unload
- Clear loose items from the work area
- Make sure equipment near the work can be switched off and left to cool

Advice
Questions from Broadfields Estate
Do you clean school canteen extracts around Broadfields Estate out of term?
Yes. The holidays are the usual time for school work. There are about 21 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Broadfields Estate. Just phone us on 0345 646 2711 or use the quote form with your term dates and we will plan around them.
What do you need to know about parking in Broadfields Estate?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Night visits tend to make loading easier on London streets.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
Can you look after several sites?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
Is it safe to clean the fan while the kitchen is open?
With the fan isolated, the extract isn’t running. That is why fan cleans are done out of hours, and the kitchen is ready when we leave.
What does extract fan cleaning cost?
It depends on the site, so we quote each one individually. For a quote, ring 0345 646 2711 or email us with the site type, opening hours and a few photos.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Can the work be done while we are closed?
Yes, and that is how we prefer to work. We book the visit for when the area is out of use, such as late evening, overnight or a weekend.
When to call us in Broadfields Estate
A fan collects more grease when the filters let more through. Missing, damaged or badly fitted filters let grease travel the whole system, so the fan takes far more than it should.
It’s time to book a visit if you see:
- A fan left out of previous cleans
- A fan that no longer moves enough air
- A heavily greased fan housing
- A noisy fan that has got louder over time
Historic houses near Broadfields Estate, such as Headstone Manor about 4.1 miles south-west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
Before booking anyone
- Whether inaccessible sections are listed on the report
- When they can work, and whether that is outside your opening hours
- Whether a survey comes first
- Which accreditations they hold, and whether you can check them
Looking after it afterwards
Once we’ve finished, these simple steps help:
- Note any drop in extraction at the canopy
- File the fan’s report with your other records
- Keep access to the fan clear
- Notice when the fan starts to sound different
Keep the report with the maintenance log and fire risk assessment. It gives a dated record of the fan’s condition, which helps if anything changes later.
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.
What a clean will not put right
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- Grease in the canopy and ductwork
- A failed motor or worn bearings (that needs a fan repair or replacement)
- A fan that was never right for the kitchen
Not sure which it is? You can phone us on 0345 646 2711 or use the quote form and we will tell you honestly before you book.

How the job changes from site to site
Fan housings and motors
Inside the casing, grease is thrown onto the walls. It’s scraped and degreased with the impeller.
Roof-mounted fans
A roof fan sits in cooler air, so grease can settle heavily. We scrape and degrease the blades and casing.
What extract fan cleaning looks like in Broadfields Estate
The Food Standards Agency lists about 7 pubs and bars and about 3 hotels, B&Bs and guest houses as registered food businesses within roughly a mile and a half of the centre of Broadfields Estate. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Night work suits London kitchens, and roads and loading bays tend to be quieter too. Kitchens in Broadfields Estate get their food hygiene inspections from Barnet council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.
If you run a church or community hall kitchen, near St Andrew or elsewhere in Broadfields Estate, its extract still collects grease from every lunch and event. Bursars and site managers at schools such as Rosh Pinah Primary School tend to book extract cleaning for when the kitchen is empty.
