Commercial kitchen extraction cleaning in Whetstone
The part of the system nobody sees is often the dirtiest. Access panels let us into the duct runs and risers, scraping heavy deposits by hand before degreasing. Any section we can’t reach is recorded on the report and extra access panels can be added. If you’re dealing with grease drips onto cooking equipment and stale cooking odours from the system, we can help, from vertical risers, horizontal duct runs and plenums and filters onwards. Extraction cleaning, hood cleaning and TR19 duct cleaning all end up in the same place: a system that is clean inside, not just on the surface, and a certificate that proves it.
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 Whetstone goes.
Kitchens in Whetstone, 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, which is why keeping it clean to TR19® matters.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

How the job changes from site to site
Canopy and plenum
Whether it’s one hood or a long island canopy, each section is cleaned and photographed before and after.
Grease filters
A filter that’s missing or bent lets grease straight past. We check they fit as they should when we refit them, and flag any that don’t.
What happens on the day
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes a single shift for most kitchens, with long duct runs and tall risers needing more time, and the area is cleaned down before we leave. Getting kit into a London building takes planning, so let us know where we can load and park in Whetstone.
- First the diagnosis: a survey of the whole system and its access points.
- We record grease levels at set points, then fix the price.
- We arrive after close, protect the area and contain the waste.
- Heavy deposits are scraped by hand and the system degreased to TR19® Grease.
- The sign-off: post-clean readings, a TR19 certificate and a photo report with the next clean date.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Dig out any earlier paperwork for the system
- Mention any locked doors, roof access or ceiling voids

Advice
Kitchen extracts in Whetstone
The FSA’s data shows about 31 bars, pubs and nightclubs registered across Whetstone and its immediate surroundings (about a mile and a half). Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. In London, kitchens are usually cleaned overnight, when the kitchen is closed and loading is easier. London Fire Brigade covers Whetstone. 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 cook for passing trade around Oakleigh Park station, the extract can be cleaned between your last and first customer. Volunteers running a hall kitchen near Church of St John, or anywhere in Whetstone, may not know when the extract was last cleaned, and a grease test settles it.

Signs you need kitchen extract cleaning in Whetstone
Grease in the extract matters because it burns. A flare-up on the range can be drawn up into the canopy and duct, where burning grease can carry a fire along the ducts and into other parts of the building. That’s why controlling extract grease belongs in the fire risk assessment.
Any of these means the system needs a check-up:
- Rancid smells from grease in the duct
- Years of baked-on grease in the ducts
- Proof of cleaning requested by an insurer
- An extract that has never been cleaned to TR19
If you look after a school kitchen, at a school such as Queenswell Infant & Nursery School or anywhere near Whetstone, the holidays are the usual time for a TR19® clean.

Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.

How we price kitchen extract cleaning
You’ll get a fixed price before work begins. It’s based on:
- Whether we need access equipment or extra panels
- Site rules, permits and inductions
- The number of sites or systems
- The scale of the work
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
Asking for a quote
Before you ask for a quote, gather:
- Any access panels or hatches you can see
- Wide photos of the system and the area around it
- Any symptoms, from odd noises to smells or leaks
- Where the site is and what kind of site it is
We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, phone us on 0345 646 2711 or send us an email.
Whetstone: your questions answered
Do you clean school canteen extracts around Whetstone out of term?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 47 schools, colleges and universities with registered kitchens within about a mile and a half of Whetstone. Just phone us on 0345 646 2711, or email photos with your term dates and we will plan around them.
Do you work overnight in Whetstone?
Yes, out-of-hours work is a big part of what we do. The work in Whetstone can fit around your hours. Let us know the hours you’re closed and we’ll book within them.
What’s the right cleaning interval for a kitchen extract?
That comes down mainly to daily cooking hours. Heavy use of 12 to 16 hours a day calls for a clean at least every 3 months under BESA guidance, and lighter use less often. Your report gives a recommended next clean date.
Why do insurers care about extract cleaning?
Many policies require TR19 cleaning, and insurers often ask to see the certificate. Without proof, a claim can be refused or reduced, so it’s worth checking your policy wording.
What about areas you cannot get to?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
How long does it take to clean a kitchen extract system?
It takes a single shift for most kitchens, with long duct runs and tall risers needing more time. We will confirm the time when we quote.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Each site gets its own report and pictures.
Honest limits
It’s worth knowing the limits before booking:
- Fire dampers that will not close (that needs damper testing and remedials)
- Blocked drains from a neglected grease trap (a separate service)
- Ductwork that is corroded, split or leaking (that is for a ductwork contractor)
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we will say what we think.
Parts of the system we cover
- Discharge points
- Vertical risers
- Canopies and hoods
- Horizontal duct runs
- Extract fans
- Plenums and filters
Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is 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, next to our reports.
