Extract fan cleaning in Cheam
The extract fan is the heart of the system: it draws the air through the canopy and ductwork and pushes it outside. Grease that gets past everything else ends up on its blades and housing, and that is what we clean. We are often asked to deal with an extract fan with no cleaning record and fat spreading onto the roof or wall by the fan, across discharge points, in-line fans and roof-mounted fans.
Kitchens in Cheam, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
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 grease that has passed the filters is out of reach. That part needs specialist access and equipment.
What we are called out for in Cheam
Each blade collects a slightly different amount. The difference throws the impeller off balance, wearing bearings and mounts. Left too long, grease turns into wear.
These are the problems we see most often:
- A fan that hums, whines or rumbles
- Hot, greasy smells near the fan
- Fat spreading onto the roof or wall by the fan
- Less air being pulled from the kitchen
A hall kitchen that only cooks for events, whether near Church of St Andrew or elsewhere in Cheam, still needs its extract cleaned, just less often.

What affects the quote in Cheam
Sites vary more than people expect. The main factors:
- The number of sites or systems
- Access, including roofs, risers and ceiling voids
- What state the system is in
- A single visit or a regular plan
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and the price is agreed before we start.
Helping us quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Your last certificate, test record or report
- Your opening hours and when the area is out of use
- Detail shots of panels, filters and grilles
- The roof, plant room or outside wall the system runs to
Quoting starts with a diagnosis, either from photos 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.
FAQs for Cheam
How do you handle parking and loading in Cheam?
London parking can be tight, so details of loading bays and permits help. Night visits tend to make loading easier on London streets.
Do you clean school canteen extracts around Cheam out of term?
Yes. Half-terms and the summer break are the natural time for school work. Around Cheam, the Food Standards Agency lists about 15 schools and colleges with registered kitchens within a mile and a half or so. Just ring 0345 646 2711 or email us with your term dates and we’ll plan around them.
Is Cheam in your area?
Yes. Our technicians work in Cheam, as part of our area across London and the South East.
Do you offer extract fan cleaning separately?
Yes, if the fan needs it. We’ll often suggest checking the duct too, as a greasy fan normally means a greasy duct, but the choice is yours.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
What’s the cleaning interval for an extract fan?
The fan follows the full system’s interval at BESA’s minimum intervals for your cooking hours. Readings may show it needs cleaning more often.
Why has my extract fan got louder?
Grease on the blades and housing is one of the usual causes, because it unbalances the fan. It can also be wear in the bearings or motor, which our report will flag.
Is it safe to clean the fan while the kitchen is open?
The fan is isolated before we open it, so it can’t run during the clean. That means the extract is off, so we clean while the kitchen is closed.
Why it’s worth doing now in Cheam
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. It’s better booked as a planned job in Cheam than handled as an emergency.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, ring 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.

What the work involves, part by part
Impellers and blades
Coated blades move less air. Scraping and degreasing them restores their shape, so the fan can run as intended.
Inline duct fans
Hidden in a ceiling void, an inline fan is easily missed. The survey makes sure it’s part of the clean.

Kitchen extracts in Cheam
Food Standards Agency records list about 109 restaurants, cafés and canteens and about 33 takeaways and sandwich shops within about 1.5 miles of central Cheam. Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. Night work suits London kitchens, and roads and loading bays tend to be quieter too. Cheam is covered by 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.
If you look after a school kitchen, at a school such as Glaisdale School or anywhere near Cheam, the holidays are the usual time for a TR19® clean. If you run a café or takeaway near Cheam station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.
