Kitchen duct cleaning in Kings Langley
The canopy over the range is only the start of a kitchen extract system. Beyond the filters run the plenum, the ducts and risers, the fan and the point where air leaves the building, and grease settles in every one of them. A TR19® Grease clean deals with the whole route, not only the parts on show. The work covers canopies and hoods, horizontal duct runs and vertical risers, and people most often call us about a smoky, hot kitchen with weak extraction and proof of cleaning requested by an insurer. If you need a kitchen extract clean in Kings Langley, you get one team and one number for every site, wherever you are in Hertfordshire.
Kitchens that fry and grill hardest need the most frequent cleans, so the interval is set by what you cook as well as how long.
For a smaller kitchen near Kings Langley, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. We plan the visit around your hours, with the journey sorted in advance.
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. It shows what was done and what, if anything, couldn’t be reached.

Kitchen extract cleaning in Kings Langley: the local picture
According to Food Standards Agency records, there are about 12 pubs and bars within 1.5 miles or so of the middle of Kings Langley. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Hertfordshire Fire and Rescue Service covers Kings Langley. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. It’s Dacorum council that sends environmental health officers to food businesses in Kings Langley. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after photos from each clean are a simple way to show the extract is in hand.
Where a hall near Church of All Saints, or anywhere in Kings Langley, hosts lunch clubs or events, its extract gathers grease just as a café’s does. A kitchen near Kings Langley station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

Your questions about kitchen extract cleaning in Kings Langley
Can the work in Kings Langley be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Kings Langley needn’t be disturbed. Just call 0345 646 2711, or send details by email with your opening times and we will plan around them.
Who inspects food businesses in Kings Langley?
The local authority for Kings Langley is Dacorum council, and its environmental health team does the inspecting. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. We typically quote within one working day, and emergencies are covered by our 24/7 line.
What does a TR19 kitchen extract clean include?
A TR19 Grease clean covers the full extract route, not just the canopy. Canopy, plenum, filters, ductwork, risers, fan and discharge are all included, reached through access panels where needed.
Is there a survey before the work?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What does TR19 mean?
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 if parts of the system can’t be reached?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
Do I have to clean my extract to TR19 by law?
The legal duty sits in the Fire Safety Order 2005 rather than in TR19 itself. TR19 is the industry benchmark for meeting that duty in a kitchen extract, and many insurers ask for proof of it.
The process
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes anything from a few hours to a full night, depending on the size of the system. Everything the job in Kings Langley needs is worked out beforehand, from the survey.
- We start with a survey, so we know every part of the system before we quote.
- Set points are tested for grease thickness and the quote is fixed before any work starts.
- Once the kitchen has closed and the equipment has cooled, we sheet and protect the area.
- 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
- Clear loose items from the work area
- Name a contact who can let us in at the agreed time
- Let us know about parking and loading
Getting a quote
Quotes are quick. Send a few details and pictures, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

What the work involves, part by part
Schools, hospitals and care homes
Institutional kitchens tend to cook to set hours, so cleans can be booked when the kitchen is closed. The certificate goes straight into the site’s maintenance records.
Extract fan and discharge
Grease that reaches the fan coats the blades and the housing. We isolate it, open it up and degrease it.
Multi-site and managed buildings
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
When to call us in Kings Langley
Cooking fat leaves the pan as a fine vapour. As the air cools on its way through the duct, the fat condenses and sticks, and the layer grows a little with every meal cooked. The grease filters stop some, never all of it.
The symptoms we’re asked about most are:
- An overdue clean flagged by an EHO or fire officer
- Years of baked-on grease in the ducts
- Fat running down the canopy edge
- A new tenancy or takeover with no cleaning history
Healthcare kitchens, like those at hospitals such as Leavesden Hospital (about 1.9 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands.

When it’s something else
A few issues sit outside what this work can do:
- Fat blocking the kitchen drains
- Damaged duct sections that need replacing
- Faulty fire dampers in the duct
If you’re not sure, just call 0345 646 2711, or email photos and we will give you a straight answer before you book.
What we work on in Kings Langley
- Discharge points
- Horizontal duct runs
- Canopies and hoods
- Vertical risers
- Plenums and filters
- Extract fans
Keeping the system healthy
A little care between visits keeps the system in better shape. Our advice:
- Keep the baffle filters clean
- Tell us when the extract starts to drip or smell
- Clean grease off the canopy surfaces regularly
- Run the extract fan throughout cooking
A TR19 certificate notes the date, the location and the technician. File it with the fire risk assessment and the maintenance log, so it’s to hand when an insurer, fire officer or EHO asks.
Stick to the cleaning interval on the certificate. If the kitchen starts cooking longer hours, the interval should be looked at again, and grease readings will show it.
What staff can safely do
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
