Commercial kitchen extraction cleaning in Flamstead
Think of it as a health check for the kitchen’s airways: diagnose with a survey, treat with a thorough clean, then sign it off. The sign-off is a TR19 certificate with a photo report, issued through the BESCA Vent Hygiene Elite portal. The work covers canopies and hoods, extract fans and horizontal duct runs, and people most often call us about fat running down the canopy edge and a kitchen taken over without any extract records. Kitchen extract cleaning, TR19 cleaning, extraction cleaning: whatever you call it, it’s the job we do every week across Hertfordshire.
Most kitchens in Flamstead fall into one of BESA’s three bands: 3-monthly for heavy use, 6-monthly for moderate use and yearly for light use, adjusted by what the grease readings show.
In a small place like Flamstead, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What staff can safely do
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.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.

Questions from Flamstead
Which fire and rescue service is responsible for Flamstead?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Flamstead. 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.
Will you come out to Flamstead?
Yes, we work in villages as well as towns, and Flamstead is covered. The journey is planned ahead, so a few details about the route help.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it does not spread.
Which parts of the extract do you clean?
Everything from canopy to discharge: the canopy, the plenum behind the filters, the filters, horizontal ducts, vertical risers, the fan and the discharge, plus attenuators where fitted. Any part without access is noted.
Why do insurers care about extract cleaning?
Extract grease is fuel for a kitchen fire, which is why many insurers require TR19 cleaning. Our certificate and photo report give you that evidence.
Will the clean disrupt our service?
The clean is done when the kitchen isn’t cooking, so evenings, overnight, early mornings and weekends are all options. We need the equipment switched off and cooled first.
What a clean won’t put right
We will always give you a straight diagnosis, so here’s what kitchen extract cleaning won’t do:
- A duct that’s holed or coming apart
- A broken extract fan that will not run
- Fat blocking the kitchen drains
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we’ll say what we think before you book.
What the work covers
- Vertical risers
- Plenums and filters
- Extract fans
- Horizontal duct runs
- Canopies and hoods
- Discharge points
What we do, step by step
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes a few hours for a small kitchen, longer for a large system. Pictures of the system and its access let us plan the work in Flamstead before we set off.
- We survey the system first, from your photos and details or on a site visit.
- 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.
- We clean the canopy, plenum, filters, ducts, risers, fan and discharge.
- Finally the system is re-tested and photographed, and the certificate and report follow.
Before we arrive
- Arrange a key holder or contact on site
- Plan for cooking equipment or plant to be off before we arrive
- Agree a time when the area can be out of use
How to get a quote
For a fixed quote, phone us on 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. We typically come back within one working day.

When to call us in Flamstead
Grease in an extract starts as 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.
What we are most often called out for:
- Poor airflow at the canopy
- Cleaning needed before an insurance renewal or survey
- A system with no record of a TR19 clean
- Grease drips onto cooking equipment
If you run a church or community hall kitchen, near Church of St Leonard or elsewhere in Flamstead, its extract still collects grease from every lunch and event.
Questions to ask before you book
- How areas they cannot reach will be recorded
- Whether the work can be done while the site is closed
- When the next visit should be, and why
- Whether a survey comes first
How we price kitchen extract cleaning
We quote each job individually. These are the things that affect it:
- The scale of the work
- How many systems or sites are involved
- Any permits to work or inductions
- A single visit or a regular plan
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
Asking for a quote
There’s no need for technical detail. Just send:
- The paperwork from the last visit, if you have it
- Any access panels or hatches you can see
- How we’d reach plant on a roof or in a plant room
- The site address and the type of premises
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, phone us on 0345 646 2711, or email photos.
What the work involves, part by part
Ductwork and risers
Horizontal runs collect grease as the air slows and cools. We open access panels along the route and clean each section, recording any that can’t be reached.
Extract fan and discharge
The fan pulls the air through the whole system, and grease that gets past everything else ends up on its blades. We isolate it, open it up and degrease it.
Kitchen extract cleaning around Flamstead
The Food Standards Agency lists about 4 pubs and bars as registered food businesses within about 1.5 miles of central Flamstead. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Flamstead is covered by Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Kitchens in Flamstead get their food hygiene inspections from Dacorum council. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready.
Healthcare kitchens, like those at hospitals such as Hemel Hempstead Hospital (about 5 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands. If your kitchen is in a listed or historic building, like the houses around Flamstead (Childwickbury Manor is about 4.6 miles south-east), fitting access panels needs care.

Why it’s worth doing now in Flamstead
Putting it off simply moves the grease further down the duct. Over time, soft grease bakes into a harder, thicker crust, which is slower to clean. Regular cleans keep each visit shorter. If the system at a site near Flamstead fails, there may be nowhere nearby to move to.
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before any work starts.
