Kitchen extract cleaning in Barwick, Hertfordshire
Kitchen extract cleaning for commercial sites in Barwick and across Hertfordshire. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Grease dripping from the canopy or filters
- An extract that no longer clears the smoke
- A system with no record of a TR19 clean
For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare in Barwick and across Hertfordshire. Larger estates can be phased building by building around the people who use them.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
About our kitchen extract cleaning in Barwick
Any kitchen we clean in Barwick gets exactly the same specification as everywhere else we work. We survey first and take grease readings, then clean the canopy, plenum, filters, ducts, fan and discharge. At the finish there’s a TR19 certificate and a before and after photo report. We are often asked to deal with a kitchen taken over without any extract records and stale cooking odours from the system, on horizontal duct runs, discharge points and extract fans. Kitchens in Barwick book us for TR19 cleaning for three reasons: the insurer asked, the EHO asked, or the canopy is dripping. Either way, the answer is the same: a proper clean and the paperwork to match.
Before we clean, we look at where the grease is: wet film or deposit thickness readings show which parts of the duct need the most attention, and readings afterwards go into your report.
For a kitchen in or near Barwick, the visit is planned around opening hours and the journey, 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.
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’re fully insured.

How it works
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes as long as the system needs, from a few hours to several planned visits. If the van will struggle with a lane or gateway near Barwick, let us know and we’ll plan around it.
- First the diagnosis: a survey of the whole system and its access points.
- Grease readings set the baseline, and a fixed quote follows.
- We arrive after close, protect the area and contain the waste.
- Heavy deposits are scraped by hand and the system degreased to TR19® Grease.
- The sign-off: post-clean readings, a TR19 certificate and a photo report with the next clean date.
How to prepare
- Arrange a key holder or contact on site
- Move anything stored near the system
- Tell us about site rules, permits or sign-in
Ask for a quote
To get a fixed quote, ring 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. You will usually have a quote within one working day.
Advice
Your questions about kitchen extract cleaning in Barwick
Do you cover smaller places like Barwick?
Yes. Barwick is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Who inspects food businesses in Barwick?
In Barwick, it’s East 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.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
Do insurers need proof of extract cleaning?
Many insurers ask for proof of regular cleaning to TR19, and many policies require it. An insurer may refuse or reduce a claim if there’s no evidence, so it’s worth checking your policy wording.
What’s the right cleaning interval for a kitchen extract?
Under BESA guidance, the minimum depends on how long you cook each day: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Measured grease levels set the real interval.
Is TR19 a legal requirement?
No law names TR19 directly, but the Fire Safety Order 2005 does require the responsible person to manage fire risk. Insurers, fire officers and EHOs look to TR19 as the standard, and many policies require it.
What does a TR19 kitchen extract clean include?
Everything from canopy to discharge: canopy inside and out, plenum, grease filters, ductwork, risers, extract fan and discharge, plus attenuators where fitted. Any part without access is noted.
Do we have to close the kitchen for the clean?
The clean is done when the kitchen isn’t cooking, working evenings, overnight or at weekends to suit you. We need the equipment switched off and cooled first.
What kitchen extract cleaning can’t fix
Some problems need a different service or another trade:
- A duct that’s holed or coming apart
- A grease trap that needs emptying
- An undersized canopy or fan
If you are not sure, just give us a ring on 0345 646 2711 or send us an email and we’ll give you a straight answer.
What the work covers
- Horizontal duct runs
- Plenums and filters
- Vertical risers
- Discharge points
- Extract fans
- Canopies and hoods
Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Give the canopy a daily wipe
- Clean the grease filters regularly between TR19 cleans
- Book the next clean before the date on the report
- Run the extract fan throughout cooking
Any section without access is marked on the report. That’s part of an honest TR19 clean, not a failing, and we can fit access panels so it’s reached next time.
Clean the grease filters often, not just on clean day. A filter that is clean and seated properly stops more grease getting into the plenum, so the ductwork stays cleaner for longer.
What kitchen extract cleaning looks like in Barwick
Food hygiene inspections in Barwick are the job of East Hertfordshire council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready. Hertfordshire Fire and Rescue Service covers Barwick. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Where a hall near St Mary's, or anywhere in Barwick, hosts lunch clubs or events, its extract gathers grease just as a café’s does. If you run catering at a historic house or estate in the area (Much Hadham Palace is about 2.9 miles east), event kitchens in older buildings often have awkward duct runs that need planning.

Around Barwick

What the work involves, part by part
Extract fan and discharge
The discharge is where air leaves the building, which can collect grease and stain the surface around it. It’s cleaned as far as safe access allows, and any limits are recorded.
Canopy and plenum
The plenum is out of sight behind the filters, so it’s easy to forget. With the filters out, the plenum is scraped and degreased.
Also in Barwick
Do you need kitchen extract cleaning in Barwick?
How fast grease builds up depends mostly on how long the kitchen cooks each day. BESA guidance sets minimum cleaning intervals of every 3 months for 12 to 16 hours a day, 6 months for 6 to 12 hours, and 12 months for 2 to 6 hours. They are minimums: measured grease levels set the real interval.
Any of these means the system needs a check-up:
- Cleaning needed before an insurance renewal or survey
- A system with no record of a TR19 clean
- Missing paperwork after a change of operator
- Poor airflow at the canopy
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Barwick is Hertford County Hospital, about 5.8 miles south-west.

- Whether the quote is based on a survey or photos
- How areas they can’t reach will be recorded
- Whether the figure could change on the day
Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
