Typical jobs include a fan shaking on its mounts and a smell of hot grease from the extract, on roof-mounted fans, fan housings and axial fans.

Your questions about extract fan cleaning in Winchmore Hill
Can you work in Winchmore Hill outside opening hours?
Yes, we can come after you close and finish before you open. It means the site in Winchmore Hill keeps running as normal. Your opening times are the first thing we ask for.
Do you clean school canteen extracts around Winchmore Hill out of term?
Yes, out-of-term visits are normal for schools. Around Winchmore Hill, the Food Standards Agency lists about 39 schools and colleges with registered kitchens within a mile and a half or so. Just phone us on 0345 646 2711 or drop us a line with your term dates and we’ll plan around them.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
What’s the cleaning interval for an extract fan?
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.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What paperwork do I get after a fan clean?
A photo report, including the fan’s condition and the next clean date. File it with your other extract records.
How long will it take to clean the fan?
Allow a few hours where there are several fans or heavy deposits. We’ll confirm the time when we quote.
Leave it or put it right?
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 booked night’s work in Winchmore Hill costs you no trading time; an unplanned closure does.

When to call us in Winchmore Hill
Fans that are hard to reach are often the ones that get missed. If it wasn’t included in past cleans, it may hold years of grease, and the report will show it.
Any of these means the system needs a check-up:
- A fan shaking on its mounts
- A fan left out of previous cleans
- A fan motor running hot under a coat of grease
- A smell of hot grease from the extract
A hall kitchen that only cooks for events, whether near Holy Trinity or elsewhere in Winchmore Hill, still needs its extract cleaned, just less often.
What your quote should include
- Whether they recommend a next date
- Which accreditations they hold, and whether you can check them
- What paperwork you get at the end
- What’s included in the scope, part by part
Fixed quotes for extract fan cleaning in Winchmore Hill
The survey tells us what the work involves. We look at:
- The times the site is available
- Where the site is and how we reach it
- The number of sites or systems
- Site rules, permits and inductions
What you pay depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.
What to send for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- When the site is open and when it’s quiet
- The postcode and the type of business
- Detail shots of panels, filters and grilles
- Your last certificate, test record or report
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, before work begins.
What happens on the day
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes a few hours where there are several fans or heavy deposits. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Winchmore Hill.
- Diagnosis first: we look for grease, noise and vibration.
- With the fan isolated, the housing is opened.
- Each blade is cleaned so the impeller runs evenly.
- We clean the casing, the outlet and around the motor.
- We run the fan and note its condition in the photo report.
How to prepare

Advice
Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
When something else is needed
Some problems need a different service or another trade:
- A dirty duct upstream of the fan
- A fan that won’t 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 will give you a straight answer.
Parts of the system we cover

Part by part
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.
Impellers and blades
The impeller is the spinning part that moves the air, and grease builds up on them unevenly. That’s what unbalances the fan, so it’s cleaned carefully blade by blade.
