Kitchen extract cleaning for kitchens and businesses in St Johns
The ducts are where most of the grease hides. We reach horizontal runs and vertical risers through access panels, scraping heavy deposits by hand before degreasing. Any section we cannot reach is recorded on the report and extra access panels can be added. The work covers vertical risers, horizontal duct runs and extract fans, and the jobs we see most are grease dripping from the canopy or filters and a new tenancy or takeover with no cleaning history. People looking for “duct cleaning near me” in St Johns usually mean the kitchen extract, and that’s our main job: the whole run from hood to roof, cleaned to TR19® Grease.
BESA sets minimum intervals by hours of cooking a day: 3-monthly for heavy use, 6-monthly for moderate use and yearly for light use, with grease readings setting the real interval.
Kitchens in St Johns, 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.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

FAQs for St Johns
Is parking a problem for work in St Johns?
Tell us where a van can stop near your site in St Johns, and about any building rules on loading. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Do you work overnight in St Johns?
Yes, evening, overnight and weekend work is normal for us. That way a site in St Johns does not have to lose a day’s trading. Let us know the hours you’re closed and we’ll book within them.
How do you protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
Which parts of the extract do you clean?
Every part the air passes through, as far as access allows. Where there are not enough access panels to reach a section, it’s recorded, and we can fit new ones.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What paperwork comes with a kitchen extract clean?
You get both a certificate and a photo report. They belong in the maintenance log, ready for your insurer or an inspection.
Which kinds of sites do you work on?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
How often should a kitchen extract be cleaned?
BESA guidance gives minimum intervals of 3, 6 or 12 months, depending on daily cooking hours. Kitchens that fry or grill a lot may need cleaning sooner, which grease thickness testing will show.

What we do, step by step
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Before any visit in St Johns, we agree where the van can stop and how equipment reaches the system.
- We start with a survey, so we know every part of the system before we quote.
- We measure the grease at set points along the system, then give you a fixed price.
- With the kitchen closed and equipment off and cool, the area is sheeted.
- Canopy, plenum, filters, duct runs, risers, fan and discharge are all cleaned to TR19® Grease.
- Finally the system is re-tested and photographed, and the certificate and report follow.
Before we arrive
- Clear the space around the work
- Tell us the best time to work, such as after service or at a weekend
- Make sure equipment near the work can be switched off and left to cool
Getting a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
Advice
What happens if it’s left?
Grease that’s left only gets thicker. BESA guidance says the mean should not go above 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Heavy build-up takes longer to remove than regular cleans. Choosing the date yourself beats having a fault choose it for you.
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and why the quote is fixed before any work starts.

Staff cleaning versus specialist work
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Book the next clean before the date on the report
- Keep the baffle filters clean
- Run the extract fan throughout cooking
- Keep the cleaning records where you can find them
The kitchen is left clean and ready for the next service. Grease and dirty water are collected and taken off site, and equipment can be switched back on once we’ve gone.
Tell whoever looks after the system when something changes. Drips, odours and fan noise often mean grease is building, and a grease thickness test can confirm it.

Do you need kitchen extract cleaning in St Johns?
What’s on the menu matters as much as how much is cooked. Fryers, grills and open flames throw much more fat into the extract than gentler cooking, which is why grease readings matter more than the calendar.
What we’re most often called out for:
- Stale cooking odours from the system
- Heavy grease build-up inside the duct runs
- Grease drips onto cooking equipment
- Extraction mentioned at an environmental health visit
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Miller General Hospital is the nearest hospital to St Johns, about less than half a mile north.
Questions to ask before booking
- How VAT is shown on the quote

- What records you will receive afterwards
- How they set the interval to the next visit
What the work involves, part by part
Ductwork and risers
Vertical risers carry the air up through the building, and grease runs down their walls and pools at the base. They’re cleaned through access points along their height.
Schools, hospitals and care homes
Some healthcare kitchens never fully close. Cleans are planned between meals or overnight with as little disruption as possible.
Honest limits
Some problems need a different service or another trade:
- Ductwork that is corroded, split or leaking (that is for a ductwork contractor)
- An undersized canopy or fan
- A grease trap that needs emptying
Not sure which it is? You can call 0345 646 2711 or send us an email and we’ll tell you honestly.
