About our extract fan cleaning in South Harefield
Cleaning removes grease, not wear. If we find worn bearings, a struggling motor or damage to the impeller, we will tell you, and we also repair and replace extract fans. You’ll know whether the fan just needed cleaning or something more. We are often asked to deal with grease escaping from the fan outlet and thick grease on the impeller and casing, across roof-mounted fans, centrifugal fans and fan housings.
For a kitchen in or near South Harefield, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Common problems we fix in South Harefield
A fan on a roof or hidden in a ceiling void is easy to forget. A fan that has never been cleaned can be heavily coated, and the report will show it.
Keep an eye out for these warning signs:
- A smell of hot grease from the extract
- A noisy fan that has got louder over time
- A heavily greased fan housing
- A motor area thick with grease
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Ickenham Hall is about 2.7 miles south-east), access may need planning.
Before you book anyone
- What’s included in the scope, part by part
- What insurance they carry
- Whether inaccessible sections are listed on the report
- Whether a written report and photos are included
What we do, step by step
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes a few hours where there are several fans or heavy deposits, and we clear up before we go. If you can send photos, we can arrive in South Harefield knowing what to expect.
- First we locate the fan and agree how it’s safely isolated.
- The fan is isolated so it can’t start while we work.
- We remove the grease from the blades, impeller and casing.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- We reassemble, run the fan and photograph the result.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Clear the space around the work
- Agree a time when the area can be out of use
Get a fixed quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
When something else is needed
Not every problem is solved by extract fan cleaning, and we will tell you before work begins. It doesn’t solve:
- Wiring faults to the fan
- A dirty duct upstream of the fan
- A failed motor or worn bearings (that needs a fan repair or replacement)
Not sure which it is? You can ring 0345 646 2711, or send details by email and we’ll tell you honestly before booking.
What the work covers
- Fan housings
- In-line fans
- Axial fans
- Discharge points
- Centrifugal fans
- Roof-mounted fans
What happens if it’s left?
Grease on the fan is grease in the system. A TR19 clean that left out the fan wouldn’t cover the whole system and many insurers require the full system to be cleaned to TR19. If the system at a site near South Harefield fails, there may be nowhere nearby to move to.
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, phone us on 0345 646 2711 or send us an email, and we will explain what it covers.

Extract fan cleaning in South Harefield: the local picture
There are about 21 cafés, restaurants and staff canteens and about 5 takeaways and sandwich shops across South Harefield and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Each kitchen extract among them ends at a fan, and grease on the impeller strains the motor. Buckinghamshire Fire and Rescue Service covers South Harefield. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. It’s Hillingdon council that sends environmental health officers to food businesses in South Harefield. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready.
For schools such as Harefield Infant School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed. Where a hall near Church of St Mary the Virgin, or anywhere in South Harefield, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Questions from South Harefield
Do you work in villages like South Harefield?
Yes, South Harefield is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Can school kitchens in South Harefield be cleaned in the holidays?
Yes, holiday work suits schools best. There are about 4 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of South Harefield. Tell us your holiday dates and we will book the visit for when the site is empty.
Where does the waste go?
It leaves the site with us at the end of the visit. While we work, it’s kept contained to keep the area clean.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
Which accreditations do you hold?
Duct Doctor is 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.
Is TR19 cleaning required by law?
No. TR19® is BESA’s specification, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
What if the fan needs more than a clean?
A clean won’t mend wear. Where the fan needs repair or replacement, we can do that too, with a fixed quote first.
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. After that, simply ring 0345 646 2711 or use the quote form.
What affects the quote in South Harefield
The survey tells us what the work involves. We look at:
- Whether we need access equipment or extra panels
- Any permits to work or inductions
- The condition we find in the survey
- Working hours and out-of-hours timing
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, call us on 0345 646 2711 or drop us a line for straight advice and a fixed quote.
Asking for a quote
Before you ask for a quote, gather:
- Problems your staff have spotted
- Your last certificate, test record or report
- Wide pictures of the system and the area around it
- Any access panels or hatches you can see
To help us quote: where the site is, what it is and its opening hours, photos of the system and any previous report or certificate. Once you have those, phone us on 0345 646 2711 or drop us a line.
Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
