How we price extract fan cleaning
The survey tells us what the work involves. We look at:
- A single visit or a regular plan
- Access, including roofs, risers and ceiling voids
- What state the system is in
- The times the site is available
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
What we need to know
Before you ask for a quote, gather:
- Detail shots of panels, filters and grilles
- The paperwork from the last visit, if you have it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- When the site is open and when it’s quiet
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Then phone us on 0345 646 2711 or drop us a line.
How we handle extract fan cleaning in Merton Park
Every TR19® Grease clean includes the extract fan, but some fans need cleaning between full cleans, for example when it’s noisy or vibrating. Where only the fan is cleaned, the report says so. Common call-outs are for a noisy fan that has got louder over time and a fan coated in grease inside its housing, across discharge points, roof-mounted fans and centrifugal fans.
In a London area like Merton Park, 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.

What we’re called out for in Merton Park
Each blade collects a slightly different amount. Over time, that imbalance shakes the fan and puts strain on the bearings. What starts as a grease problem can become a mechanical one.
Signs it’s time to call us include:
- Burning smells from the fan area
- Thick grease on the impeller and casing
- Grease around the motor and its mounts
- Grease stains around the discharge
For schools such as Merton Park Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.
What your quote should include
- If the quote is a fixed price or an estimate
- Proof of accreditation you can verify
- Whether the quote is based on a survey or pictures
- Exactly which parts of the system are covered
What happens if it’s left?
A greasy fan at the discharge can spread grease onto the roof or wall around it. It marks the area around the outlet and leaves more fuel outside, which is one more reason to keep it clean. A busy site in Merton Park builds up dirt and wear quickly, so putting it off makes the eventual job larger.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

How the visit works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes an hour or two for most single fans. Security desks and permits-to-work are routine in London, so let us know what your building in Merton Park needs from us.
- We find the fan and check how it’s reached and how it’s isolated.
- The fan is isolated so it can’t start while we work.
- 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.
- The fan is put back into service, checked and photographed.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Arrange a key holder or contact on site
- Tell us where we can park and unload

Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Watch for grease marks around the outlet
- Keep the fan on whenever the range is lit
- File the fan’s report with your other records
- Notice when the fan starts to sound different
Once it’s clean, the fan is closed up and run to check it’s working smoothly. Anything we notice, like noise, vibration or a worn part, goes on the report, so you can plan any repair.
Listen to the fan. Rattles, hums or shaking can be early signs of build-up or wear and early action can save a repair.

Grease, kitchens and Merton Park
The FSA’s food hygiene register shows about 306 restaurants, cafés and works canteens and about 56 sandwich bars and takeaways in and around Merton Park, up to about a mile and a half out. Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. Food hygiene inspections in Merton Park are the job of Merton council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after photos from each clean are a simple way to show the extract is in hand. London Fire Brigade covers Merton Park. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
If you cook for passing trade around South Merton station, the extract can be cleaned between your last and first customer. If you run a church or community hall kitchen, near St Mary's Church or elsewhere in Merton Park, its extract still collects grease from every lunch and event.

Staff cleaning versus specialist work
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Merton Park: your questions answered
Do you work at weekends in Merton Park?
Yes, we can come after you close and finish before you open. The work in Merton Park can fit around your hours. When you phone us on 0345 646 2711, or email photos, mention when the site is quiet.
Do you clean school canteen extracts around Merton Park out of term?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 36 schools, colleges and universities with registered kitchens within about a mile and a half of Merton Park. Tell us your holiday dates and we’ll book the visit for when the site is empty.
How long does extract fan cleaning take?
That depends on the fan’s size, its position and how much grease there is. As a guide, it takes a couple of hours per fan, depending on its size and the build-up.
Will I get photos of the cleaned fan?
You get a photo report with before and after photos of the fan. If it’s part of a full TR19 clean, a TR19 certificate is issued too.
What information do you need?
The site address, the type of premises and your opening hours, plus pictures of the system and your last certificate or report if you have one.
How often does the fan need cleaning?
It depends on how many hours the kitchen cooks in BESA guidance. At the extremes, that is 3-monthly for heavy use and 12-monthly for light use, fan included.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. At the end, the area is cleaned down.
What if parts of the system can’t be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
