Kitchen extract cleaning in Cooper's Green
Few kitchens can stop cooking for a day so the extract can be cleaned. We work evenings, overnight and at weekends, or between services where the kitchen has a gap. Equipment is switched off and left to cool, the area is sheeted, and the kitchen is handed back ready to cook. The work covers horizontal duct runs, canopies and hoods and discharge points, and the jobs we see most are extraction mentioned at an environmental health visit and ductwork thick with old, hardened grease. Some call it canopy cleaning, others extract cleaning or duct cleaning, but in Cooper's Green, as everywhere, the insurer wants the full system cleaned, not just the hood.
Before we clean, we look at where the grease is: grease readings at set points tell us where the heaviest deposits are, and the same readings after the clean show the result.
In a small place like Cooper's Green, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before work begins, and floors and nearby surfaces are sheeted. The work itself takes one visit for most kitchens, while large or complex systems may need more than one. Rural roads and tight entrances are worth telling us about before a visit to Cooper's Green.
- First the diagnosis: a survey of the whole system and its access points.
- We record grease levels at set points, then fix the price.
- 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
- Tell us the best time to work, such as after service or at a weekend
- Plan for cooking equipment or plant to be off before we arrive
- Move anything stored near the system
Getting a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

What a clean won’t put right
To be straight with you, there are a few things this work won’t fix:
- A damper that sticks or has a damaged link
- Fat blocking the kitchen drains
- A fan motor or bearings that have failed (that needs a fan repair or replacement)
Not sure which it is? You can call 0345 646 2711, or email photos and we will tell you honestly.
What the work covers
- Discharge points
- Vertical risers
- Plenums and filters
- Extract fans
- Horizontal duct runs

What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Why it’s worth doing now in Cooper's Green
Any food business in Cooper's Green can expect visits from the council’s environmental health officers, and they look at the cleanliness of the premises and equipment, extraction included. A clean extract is one less thing to worry about on the day. Out of sight is the usual reason a rural system goes too long without attention.
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.

Common questions in Cooper's Green
Can you get to a site in Cooper's Green?
Yes. Cooper's Green is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Who enforces fire safety at workplaces in Cooper's Green?
Fire safety enforcement in Cooper's Green is handled by Hertfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Are you a BESCA Vent Hygiene Elite member?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 sit alongside that, and we’re fully insured.
Does the law say I must clean to TR19?
Strictly, the legal duty comes from the Regulatory Reform (Fire Safety) Order 2005, not from TR19. In practice, TR19 is how kitchens show they’re managing grease, and an insurer may refuse or reduce a claim without it.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Can you come out in an emergency?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Will my insurer ask for a TR19 certificate?
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.
Do we have to close the kitchen for the clean?
Cleans are timed to avoid service. Overnight, weekend and between-service cleans are all possible, so you do not lose a service.
When to call us in Cooper's Green
Grease in the extract matters because it burns. A flare-up on the range can be drawn up into the canopy and duct, and once grease in the duct catches, fire can spread through the building’s ductwork. For a kitchen in Cooper's Green, keeping that fuel under control is part of the fire risk assessment.
Common reasons sites call us are:
- Missing paperwork after a change of operator
- An extract that no longer clears the smoke
- Stale cooking odours from the system
- An overdue clean flagged by an EHO or fire officer
Term dates shape school work: for a school like Howe Dell Primary School, an extract clean fits neatly into a half-term or summer break.
Questions to ask before you book
- What insurance they carry
- What’s included in the scope, part by part
- How areas they cannot reach will be recorded
- Whether the price is fixed
Kitchen extracts in Cooper's Green
The Food Standards Agency lists about 5 pubs, bars and clubs as registered food businesses in Cooper's Green and the streets around it, up to about 1.5 miles out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Cooper's Green sits within the area of Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Environmental health officers from Welwyn Hatfield council inspect food businesses in Cooper's Green. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.

Looking after it afterwards
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Book the next clean before the date on the report
- Give the canopy a daily wipe
- Flag any change in how the extract sounds or works
- File each certificate with the fire risk assessment
A TR19 certificate notes the date, the location and the technician. Keep it in the maintenance log with your fire risk assessment so it’s ready when anyone asks to see it.
Report drips, smells or a noisy fan early. 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.
