Kitchen extract cleaning in Denham, done properly
Few kitchens can stop cooking for a day so the extract can be cleaned. Cleans are booked for evenings, overnight or weekends, or between services where the kitchen has a gap. Equipment is switched off and left to cool, the area is sheeted, and the kitchen is handed back ready to cook. The work covers plenums and filters, extract fans and canopies and hoods, and the jobs we see most are an extract that has never been cleaned to TR19 and a smoky, hot kitchen with weak extraction. When a restaurant in Denham asks for duct cleaning, it’s nearly always the kitchen extract they mean, and that is our main job: canopy to fan, to TR19® Grease.
Grease that collects out of sight, behind the filters and along the duct, is what insurers and fire officers worry about, so that is where most of the work in Denham goes.
For a kitchen in or near Denham, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
A written report with pictures follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How the visit works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes one visit for most kitchens, while large or complex systems may need more than one. A few pictures of the system help us make the most of a visit to a place like Denham.
- We survey the system first, from your photos and details or on a site visit.
- We measure the grease at set points along the system, then give you a fixed price.
- On the day, cooking equipment is switched off and left to cool, and everything nearby is sheeted.
- We clean the canopy, plenum, filters, ducts, risers, fan and discharge.
- Readings and photos are taken again, and you receive a TR19 certificate and photo report.
Getting ready for the visit
- Move anything stored near the system
- Find the previous report, if there is one
- Let us know when the site is closed or quiet

Advice
Why act early in Denham
Leaving the clean until the next refit doesn’t make the grease go away. Fat that was soft and easy to remove hardens with heat and time, which is slower to clean. Staying on a regular cycle keeps each clean manageable. In a place like Denham, ductwork and fans are easy to forget until something goes wrong.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.

What kitchen extract cleaning looks like in Denham
Food Standards Agency data counts about 78 restaurants, cafés and canteens and about 11 sandwich bars and takeaways within roughly a mile and a half of the centre of Denham. Wherever food is cooked under a canopy, the extract above it gathers grease and needs cleaning on a schedule. The fire and rescue service for Denham is Buckinghamshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Food hygiene inspections in Denham are the job of Buckinghamshire council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Denham is Harefield Hospital, about 2.8 miles north. For schools such as Denham Village School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
What we are called out for in Denham
The reason for all this is fire. Flames from a pan or grill can be pulled into the canopy by the fan, and once grease in the duct catches, fire can spread through the building’s ductwork. For a kitchen in Denham, keeping that fuel under control is part of the fire risk assessment.
Signs it’s time to call us include:
- A kitchen with no current TR19 certificate
- Grease drips onto cooking equipment
- A new tenancy or takeover with no cleaning history
- An inspection that picked up a dirty extract
If you run a café or takeaway near Denham station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

What kitchen extract cleaning cannot fix
In fairness, there are a few things this work won’t fix:
- A canopy that’s too small or a system that was badly designed
- A fan motor or bearings that have failed (that needs a fan repair or replacement)
- A damper that sticks or has a damaged link
If in doubt, ring 0345 646 2711 or email us and we’ll say what we think before booking.

Different parts, different methods
Extract fan and discharge
The fan pulls the air through the whole system, and grease that gets past everything else ends up on its blades. It’s isolated, opened and cleaned as part of the TR19 clean.
Canopy and plenum
Whether it’s one hood or a long island canopy, every section is cleaned and recorded in the photo report before and after.
Your questions about kitchen extract cleaning in Denham
Who would carry out a food hygiene inspection at a kitchen in Denham?
The local authority for Denham is Buckinghamshire council, and its environmental health team does the inspecting. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Will you come out to Denham?
Yes. Denham is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Do I have to clean my extract to TR19 by law?
TR19 isn’t written into law, but the responsible person still has a legal duty under the Fire Safety Order 2005. TR19 is the standard insurers and fire officers expect, and many policies require it.
What information do you need?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
What’s the right cleaning interval for a kitchen extract?
The minimum is set by BESA guidance on daily use, from 3-monthly to 12-monthly. Heavy frying and grilling can mean shorter intervals, and readings will tell you.
Can you come out in an emergency?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
Which parts of the extract do you clean?
The whole system: canopy inside and out, plenum, grease filters, ductwork, risers, extract fan and discharge, plus attenuators where fitted. Anything we can’t reach is recorded on the report.
Why do insurers care about extract cleaning?
Grease in an extract is a known fire risk, which is why many insurers require TR19 cleaning. Our certificate and photo report give you that evidence.
Landlords, agents and facilities managers
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
