Kitchen duct cleaning in Willian
Duct Doctor has been cleaning kitchen extract systems since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001 and are fully insured. The work covers canopies and hoods, horizontal duct runs and plenums and filters, and common reasons people get in touch are an extract that no longer clears the smoke and rancid smells from grease in the duct. Canopy cleaning, extract cleaning and duct cleaning are often used to mean the same thing, but a proper TR19® clean in Willian covers all of it, from the hood to the fan.
Access decides how thorough a clean can be. Sections without access panels are recorded on the report, and new panels can be fitted so they’re cleaned next time.
Work in a small place like Willian starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What kitchen extract cleaning looks like in Willian
There are about 49 restaurants, cafés and works canteens and about 25 takeaways and sandwich shops in and around Willian, up to about a mile and a half out, according to the Food Standards Agency’s register. Any of them cooking under a canopy is sending grease into its ductwork every service. Willian sits within the area of Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Willian, food businesses are inspected by environmental health officers from North Hertfordshire council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. 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 Willian is Lister Hospital, about 2.5 miles south. Where a hall near Church of All Saints, or anywhere in Willian, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
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.
Between visits
Results last longer with the right care. We suggest:
- Empty any grease troughs or cups on the canopy
- Keep the TR19 certificate and photo report in the maintenance log
- Keep the baffle filters clean
- Flag any change in how the extract sounds or works
If we couldn’t get into part of the duct, the report says so plainly. A TR19 report should record what wasn’t cleaned as well as what was, and we can fit access panels so it’s reached next time.
Tell whoever looks after the system when something changes. Grease dripping from the canopy, a burning smell or a fan that sounds rough are all signs of build-up, and a grease thickness test can confirm it.
What affects the cost of kitchen extract cleaning
A fixed price needs a few facts first. We look at:
- Travel, parking and unloading
- Site rules, permits and inductions
- Whether it’s a one-off visit or part of a schedule
- How big the system is
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before work begins.
Helping us quote
We can often survey from pictures. Try to include:
- The postcode and the type of business
- Detail shots of panels, filters and grilles
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide photos of the system and the area around it
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

Common questions in Willian
Who enforces fire safety at workplaces in Willian?
It’s Hertfordshire Fire and Rescue Service, which covers Willian. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Who would carry out a food hygiene inspection at a kitchen in Willian?
In Willian, it’s North Hertfordshire council that carries out food hygiene inspections. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Where does the waste go?
We take it away when we go. While we work, it’s kept contained to keep the area clean.
Do you clean the whole extract system or just the canopy?
All of it, from the canopy through to the discharge. Where there are not enough access panels to reach a section, it’s recorded, and we can fit new ones.
What does kitchen extract cleaning cost?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before work begins.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
How long does it take to clean a kitchen extract system?
Short systems are done in a few hours, but large systems may be spread over more than one visit. Your quote says how long to expect.
What accreditations do you hold?
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.
What happens if it’s left?
Environmental health officers inspect food businesses, in Willian as everywhere else, and a greasy canopy or dripping filters won’t go unnoticed. A clean extract is one less thing to worry about on the day. In a place like Willian, ductwork and fans are easy to forget until something goes wrong.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before any work starts.

Signs you need kitchen extract cleaning in Willian
A kitchen in Willian builds up grease in the same places as any other: long horizontal runs, bends, the base of risers and around the fan. The cooler the duct, the more grease drops out of the air.
What we’re most often called out for:
- Years of baked-on grease in the ducts
- A kitchen with no current TR19 certificate
- An inspection that picked up a dirty extract
- Grease drips onto cooking equipment
School kitchens, at schools like Lordship Farm Primary School for example, are typically cleaned in the holidays so no lunches are lost.
What your quote should include
- Whether the quote is based on a survey or photos
- Whether they recommend a next date
- What paperwork you get at the end
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
What we do, step by step
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a single shift for most kitchens, with long duct runs and tall risers needing more time. If you can send photos, we can arrive in Willian knowing what to expect.
- 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.
- On the day, cooking equipment is switched off and left to cool, and everything nearby is sheeted.
- The whole route is cleaned, from the canopy through the ductwork to the fan and the discharge.
- Readings and photos are taken again, and you receive a TR19 certificate and photo report.
Before we arrive
- Arrange a key holder or contact on site
- Move anything stored near the system
- Mention any sign-in, permit or induction we need
Get a fixed quote
Photos are the quickest way to a quote: 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 many jobs can be priced from that alone.

When it’s something else
We will not sell you work that does not address the problem, so here are the limits:
- A damper that sticks or has a damaged link
- A canopy that is too small or a system that was badly designed
- A duct that’s holed or coming apart
Not sure which it is? You can phone us on 0345 646 2711, or send details by email and we will tell you honestly.
