Greater London · Extract fan cleaning
Bell Green extract fan cleaning
Extract fan cleaning in Bell Green from ventilation hygiene specialists trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- A motor area thick with grease
- A fan coated in grease inside its housing
- Rough running from the extract fan
Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
How we handle extract fan cleaning in Bell Green
The fan is cleaned as part of every full TR19® Grease clean, but a fan can also need attention on its own, especially when it has started to vibrate or sound rough. Where only the fan is cleaned, the report says so. The work covers centrifugal fans, roof-mounted fans and discharge points, and people most often call us about less air being pulled from the kitchen and fat spreading onto the roof or wall by the fan.
In a London area like Bell Green, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Signs you need extract fan cleaning in Bell Green
Each blade collects a slightly different amount. Over time, that imbalance shakes the fan, wearing bearings and mounts. What starts as a grease problem can become a mechanical one.
If you notice any of these, it’s worth a diagnosis:
- Burning smells from the fan area
- A fan left out of previous cleans
- A fan coated in grease inside its housing
- Fat spreading onto the roof or wall by the fan
A hospital like St Christopher's Hospice, about 1.2 miles south-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Why act early in Bell Green
For a kitchen in Bell Green, a noisy, greasy fan is often the first sign the whole system is overdue. If the fan is coated, the duct before it normally is too, so it’s worth checking the whole system. London sites work long hours, and the longer a job is left, the bigger it gets.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.

How it works
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, 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. Most London sites cannot stop for the day, so work in Bell Green is usually done overnight, early in the morning or at weekends.
- 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
- Clear loose items from the work area
- Have your last certificate or report to hand
- Let us know about parking and loading
Getting a quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and the last certificate or report, if there is one. Once you have those, call us on 0345 646 2711 or email us.

FAQs for Bell Green
Who is the fire and rescue service for Bell Green?
Fire safety enforcement in Bell Green is handled by London Fire Brigade. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Can school kitchens in Bell Green be cleaned in the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 44 schools, colleges and universities with registered kitchens within about a mile and a half of Bell Green. Booking early in the term gives the best choice of holiday dates.
Which sectors do you work in?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
Is it safe to clean the fan while the kitchen is open?
We always isolate the fan first, so it can’t start while we work. That means the extract is off, so we clean while the kitchen is closed.
Is TR19 cleaning required by law?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
What do you need from me for a quote?
Some pictures and a quick description of the system plus the address and your hours. We’ll ask for anything else we need.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.
When something else is needed
We will always give you a straight diagnosis, so here’s what extract fan cleaning will not do:
- An impeller that’s bent or split
- Grease in the canopy and ductwork
- A faulty speed controller or isolator
Not sure which it is? You can phone us on 0345 646 2711 or email us and we will tell you honestly before booking.

What affects the cost of extract fan cleaning
A fixed price needs a few facts first. We check:
- One-off work versus a regular cycle
- How easy every part is to reach
- What state the system is in
- When the work can happen, such as evenings, overnight or weekends
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’ll have a fixed price before we start.
Asking for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any previous report or certificate
- The times we could work without disrupting the site
- Wide photos of the system and the area around it
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before any work starts.

Wall fans
Grease can mark the outside wall around the fan. We clean the fan and check the outlet.
Impellers and blades
Coated blades move less air. Scraping and degreasing them restores their shape, so the fan can run as intended.
