Extract Fan Cleaning in Finchley
Professional extract fan cleaning in and around Finchley, timed so the site keeps working and finished with a written report and pictures.
- A fan coated in grease inside its housing
- Weak extraction at the canopy
- A fan left out of previous cleans
Extract fan cleaning in Finchley, done properly
A fan never collects grease in a neat, even layer. Heavier deposits on some blades throw the impeller off balance, leading to vibration, noise and strain on the motor and bearings. A thorough clean removes the cause. We are often asked to deal with a smell of hot grease from the extract and a fan that no longer moves enough air, on fan housings, axial fans and centrifugal fans.
London kitchens tend to trade late and open early, so work in Finchley 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.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

When to call us in Finchley
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.
Clients usually contact us when they notice something like this:
- An extract fan with no cleaning record
- Grease stains around the discharge
- A motor area thick with grease
- A fan that hums, whines or rumbles
School kitchens, at schools like Manorside Primary School for example, are normally cleaned in the holidays so no lunches are lost.
Questions to ask before you book
- Whether a survey comes first
- How they set the interval to the next visit
- When they can work, and whether that’s outside your opening hours
- What records you’ll receive afterwards

Extract fan cleaning around Finchley
According to Food Standards Agency records, there are about 33 pubs and bars and about 5 hotels and guest houses within about 1.5 miles of central Finchley. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Fire safety in Finchley falls to London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Food hygiene inspections in Finchley are the job of Barnet council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Heath Hall, about 1.8 miles south, is one of the historic houses near Finchley; if you run event catering at a venue like that, cleans can be booked between functions. Healthcare kitchens, like those at hospitals such as Finchley Memorial Hospital (about under half a mile north-east), often cook for long hours, which puts them in BESA’s heavier-use bands.

Fixed quotes for extract fan cleaning in Finchley
The quote reflects the site in front of us. We take into account:
- A single visit or a regular plan
- How many systems or sites are involved
- How easy every part is to reach
- Site requirements such as sign-in and permits
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Helping us quote
What to send for a quote:
- Problems your staff have spotted
- Your opening hours and when the area is out of use
- Where the site is and what kind of site it is
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Honest limits
We’ll always give you a straight diagnosis, so here’s what extract fan cleaning will not do:
- A dirty duct upstream of the fan
- A fan that was never right for the kitchen
- Damaged fan blades
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we’ll tell you honestly.

Part by part
Roof-mounted fans
Many kitchen extracts end at a fan on the roof. They’re cleaned where safe access allows, with any limits noted.
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.
Why act early in Finchley
A fan that fails mid-service can stop a kitchen cooking. Many fan problems start with grease, so keeping it clean is part of keeping it running. If it does fail, our 24/7 emergency line is there. It’s better booked as a planned job in Finchley than handled as an emergency.
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and why the quote is fixed before any work starts.

Common questions in Finchley
Do you work at weekends in Finchley?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Just call 0345 646 2711, or email photos with your opening times and we will plan around them.
Can a school canteen extract in Finchley be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 48 schools, colleges and universities with registered kitchens within about a mile and a half of Finchley. Just ring 0345 646 2711, or email photos with your term dates and we’ll plan around them.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and we’ll quote them together.
Is it safe to clean the fan while the kitchen is open?
The fan is isolated before we open it, so it cannot run during the clean. That means the extract is off, so we clean while the kitchen is closed.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Is there a survey before the work?
Yes. Photos often do the job, and larger or hidden systems get a visit.
How much notice do you need?
Earlier is better, particularly for night and weekend visits. Quotes typically come back within one working day, and there’s a 24/7 line for emergencies.
What about areas you cannot get to?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
What we do, step by step
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes an hour or two for one fan, longer when it’s hard to reach, and the area is cleaned down before we leave. Most London sites cannot stop for the day, so work in Finchley is typically done overnight, early in the morning or at weekends.
- 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.
- We degrease the fan and housing, taking care around the motor.
- It’s closed up, run and checked, and pictures go into your report.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Clear the space around the work
How to get a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
