- Heavy grease build-up inside the duct runs
What we do, step by step
Each visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, tidy up and hand over the paperwork. The visit itself takes a single shift for most kitchens, with long duct runs and tall risers needing more time. A quick note on how to find the site and where to park makes a visit to Knotty Green run smoothly.
- You send pictures or we visit, and the system is surveyed from canopy to discharge.
- Grease thickness is measured and the price is fixed before work starts.
- On the night, the equipment is off and cool and the kitchen is sheeted.
- We work through the system from the canopy to the fan and discharge.
- Readings are repeated, photos taken, and your TR19 certificate and photo report issued.
Preparing for the visit
- Clear loose items from the work area
- Agree a time when the area can be out of use
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Kitchen duct cleaning in Knotty Green
A closed kitchen isn’t earning, so the timing of a clean matters. Cleans are booked for evenings, overnight or weekends, or during holidays where a site closes for them. With the equipment off and cool and the area sheeted, we clean and hand the kitchen back ready for the next service. If you have years of baked-on grease in the ducts and grease drips onto cooking equipment, we can put it right, from canopies and hoods, plenums and filters and vertical risers onwards. Searching for commercial kitchen extraction cleaning in Knotty Green? We’ve been cleaning kitchen extracts across the South East since 2009, as a BESCA Vent Hygiene Elite member.
The fire risk in a kitchen extract sits in the parts nobody sees: the plenum, the duct and the fan, so that is where most of the work in Knotty Green goes.
In a small place like Knotty Green, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Do you need kitchen extract cleaning in Knotty Green?
What’s on the menu matters as much as how much is cooked. Frying, grilling and roasting send far more fat into the canopy than steaming or boiling, which is why grease readings matter more than the calendar.
If you notice any of these, it’s worth a diagnosis:
- An extract that no longer clears the smoke
- Cleaning needed before an insurance renewal or survey
- An overdue clean flagged by an EHO or fire officer
- Heavy grease build-up inside the duct runs
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Amersham Hospital is the nearest hospital to Knotty Green, about 3.2 miles north-east.
Questions to ask before you book
- Whether the whole system is included, or only the parts that are easy to reach
- How they set the interval to the next visit
- What records you’ll receive afterwards
- Which accreditations they hold, and whether you can check them

Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Your questions about kitchen extract cleaning in Knotty Green
Can school kitchens in Knotty Green be cleaned in the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 6 schools, colleges and universities with registered kitchens within about a mile and a half of Knotty Green. Just call 0345 646 2711 or send us an email with your term dates and we will plan around them.
Do you cover smaller places like Knotty Green?
Yes, Knotty Green is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Do insurers need proof of extract cleaning?
Many insurers ask for proof of regular cleaning to TR19, and many policies require it. Without proof, a claim can be refused or reduced, so it’s worth checking your policy wording.
Will the clean disrupt our service?
We clean while the kitchen is closed, working evenings, overnight or at weekends to suit you. Equipment needs to be off and cool before work begins.
How much does kitchen extract cleaning cost?
Every site is different, so each gets its own fixed quote. To get one, call us on 0345 646 2711, or send details by email and tell us about the site and its opening hours.
Are you accredited for kitchen extract cleaning?
We clean to BESA TR19® Grease as a BESCA Vent Hygiene Elite member, with certificates issued through the BESCA portal. Duct Doctor has been trading since 2009.
Can you look after several sites?
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 photos.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
Landlords, agents and facilities managers
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Why deal with it now?
If your kitchen in Knotty Green is past its cleaning date, it’s worth booking now. The job takes as long as the system needs, from a few hours to several planned visits, and we fit around your opening hours. Every extra month adds grease. Out of sight is the usual reason a rural system goes too long without attention.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.

- Blocked drains from a neglected grease trap (a separate service)
If in doubt, give us a ring on 0345 646 2711 or send us an email and we will say what we think before booking.

What affects the cost of kitchen extract cleaning
The survey tells us what the work involves. The main factors are:
- Travel, parking and unloading
- Working hours and out-of-hours timing
- The condition we find in the survey
- How big the system is
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.
Asking for a quote
You do not need the technical terms. It helps if you can send:
- The site address and the type of premises
- A few general shots of the system
- The paperwork from the last visit, if you have it
- Your opening hours and when the area is out of use
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. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
