Leave it or put it right?
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. For a site in Westminster, fitting the work in overnight now is far easier than closing at short notice later.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before any work starts.

Extract fan cleaning for kitchens and businesses in Westminster
Duct Doctor has been cleaning kitchen extract fans since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, with CHAS, SafeContractor and ISO 9001 and full insurance. The work covers axial fans, discharge points and in-line fans, and the jobs we see most are a fan that has never been cleaned and burning smells from the fan area.
London kitchens tend to trade late and open early, so work in Westminster is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.
The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What affects the cost of extract fan cleaning
The price is fixed before any work begins. It takes into account:
- Access, including roofs, risers and ceiling voids
- How big the system is
- The number of sites or systems
- The condition of the system
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, give us a ring on 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.
Helping us quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- When the site is open and when it’s quiet
- Any previous report or certificate
- How we’d reach plant on a roof or in a plant room
- Close-ups of filters, grilles, hatches or access panels
If you need extract fan cleaning in Westminster, call 0345 646 2711, or email photos. Let us know the site type and the opening hours, and send pictures or your last report if you can. A fixed quote usually follows within one working day.
Signs you need extract fan cleaning in Westminster
Grease condenses as the air cools, and a fan out on a roof or wall often sits where the air is coolest. So grease often settles heavily there.
It’s time to book a visit if you see:
- Fat spreading onto the roof or wall by the fan
- Rough running from the extract fan
- An extract fan with no cleaning record
- A heavily greased fan housing
Volunteers running a hall kitchen near Christ Church, or anywhere in Westminster, may not know when the extract was last cleaned, and a grease test settles it.

- What paperwork you get at the end
- Whether VAT is included
- Whether the price is fixed
Honest limits
We’d rather tell you now than book work that will not help, so these are the things it will not cover:
- Electrical faults in the fan’s supply or controls (an electrician’s job)
- A fan that will not start
- A cracked or broken impeller (it needs replacing)
If you’re not sure, just ring 0345 646 2711, or send details by email and we’ll give you a straight answer.
What the work covers
- Discharge points
- Fan housings
- Roof-mounted fans
- Centrifugal fans
- In-line fans
- Axial fans
Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Do not turn the fan off mid-service
- Tell us if the extract feels weaker
- Don’t store items in front of the fan’s access point
- Report rattles or humming early
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.
Listen to the fan. New noise or vibration often means grease is building on the impeller and early action can save a repair.
What staff can safely do
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
The process
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, it takes an hour or two for most single fans. Before any visit in Westminster, we agree where the van can stop and how equipment reaches the system.
- First we check the fan’s condition and how it sounds.
- Once isolated, we open the fan up.
- 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.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure equipment near the work can be switched off and left to cool
- Arrange a key holder or contact on site
Getting a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711, or email photos.

Your questions about extract fan cleaning in Westminster
Who enforces fire safety at workplaces in Westminster?
London Fire Brigade is the fire and rescue service for Westminster. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Do you clean school canteen extracts around Westminster out of term?
Yes, out-of-term visits are normal for schools. Around Westminster, the Food Standards Agency lists about 85 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Is the fan isolated during cleaning?
With the fan isolated, the extract isn’t running. We work evenings, overnight or weekends, and the kitchen is ready when we leave.
What do you do with what you remove?
We take it away when we go. While we work, it’s kept contained to keep the area clean.
What’s the cleaning interval for an extract fan?
With the whole system, at intervals set by BESA guidance: every 3, 6 or 12 months. Some fans need attention sooner.
Why is my extract fan noisy?
Often it’s grease on the impeller. Grease collects unevenly and unbalances the impeller, causing vibration and noise. Cleaning may sort it, but worn bearings or a failing motor need a repair.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Extract fan cleaning around Westminster
Food Standards Agency records include about 260 pubs, bars and clubs and about 187 hotels and B&Bs within about 1.5 miles of central Westminster. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Most London extract cleaning happens at night, after the last service. Fire safety in Westminster falls to London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
School kitchens, at schools like Harris Westminster Sixth Form for example, are typically cleaned in the holidays so no lunches are lost. Commuter trade near London Victoria station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.
