How we handle kitchen extract cleaning in Radwell
The canopy over the range is only the start of a kitchen extract system. Behind it sit the plenum and grease filters, then the ductwork, risers, extract fan and discharge, 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 discharge points, horizontal duct runs and canopies and hoods, and people most often call us about cleaning needed before an insurance renewal or survey and an extract that no longer clears the smoke. Kitchen extract cleaning, TR19 cleaning, extraction cleaning: whatever you call it, in Radwell it means the same thing to us: the whole system, cleaned and certificated.
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 the same readings after the clean show the result.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
A written report with photos follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
What kitchen extract cleaning looks like in Radwell
Food Standards Agency records include about 10 bars, pubs and nightclubs within about 1.5 miles of central Radwell. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Kitchens in Radwell get their food hygiene inspections from North Hertfordshire council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked. Hertfordshire Fire and Rescue Service covers Radwell. 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.
Hinxworth Place, about 2.4 miles north, is one of the historic houses near Radwell; if you run event catering at a venue like that, cleans can be booked between functions. If you run a church or community hall kitchen, near Church of All Saints or elsewhere in Radwell, its extract still collects grease from every lunch and event. If you look after a school kitchen, at a school such as Norton St Nicholas CofE (VA) Primary School or anywhere near Radwell, the holidays are the usual time for a TR19® clean.

What we do, step by step
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a few hours for a small kitchen, longer for a large system. Somewhere like Radwell, lanes, gates and parking are worth mentioning in advance.
- We survey the system, from your pictures or on site, canopy to discharge.
- We take grease readings at set points and send you a fixed quote.
- The kitchen is closed, the equipment cooled and everything nearby protected.
- Filters, canopy and plenum are cleaned, then the ducts, risers, fan and discharge.
- We re-test, photograph and send your certificate and photo report.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Mention any parking or loading restrictions
- Allow time for equipment near the work to be turned off and cool down
Getting a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before we start.
Advice
Fixed quotes for kitchen extract cleaning in Radwell
The survey tells us what the work involves. We look at:
- Any permits to work or inductions
- The number of sites or systems
- The size of the system
- What state the system is in
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.
What to send for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- When the site is open and when it’s quiet
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Close-ups of filters, grilles, hatches or access panels
- Where the site is and what kind of site it is
For kitchen extract cleaning in Radwell, call us on 0345 646 2711 or drop us a line. Let us know the site type and the opening hours, and send pictures or your last report if you can. We typically send a fixed quote within one working day.
What happens if it’s left?
If there’s a fire and the extract hasn’t been cleaned, the paperwork becomes the problem. Many policies require cleaning to TR19, and an insurer can refuse or reduce a claim without proof. A certificate in the file answers that question. Equipment tucked in a roof space or outbuilding near Radwell rarely gets looked at unless someone books it.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, phone us on 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.

What the work involves, part by part
Grease filters
Between TR19 cleans, filters still need regular cleaning and we offer a filter exchange service for that. Clean filters slow the build-up further down the system.
Restaurant and pub kitchens
Restaurants and pubs tend to cook long hours with plenty of frying and grilling, which can put them in BESA’s 3 or 6-monthly bands. Cleans are done after close, overnight or before opening.
Your questions about kitchen extract cleaning in Radwell
Will you come out to Radwell?
Yes. Radwell 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.
Do you clean school canteen extracts around Radwell out of term?
Yes, out-of-term visits are normal for schools. With about 5 schools and colleges on the FSA’s register within roughly a mile and a half of Radwell, it pays to plan holiday dates ahead. Just phone us on 0345 646 2711 or email us with your term dates and we will plan around them.
What does a TR19 kitchen extract clean include?
We clean every part the grease travels through. Canopy, plenum, filters, ductwork, risers, fan and discharge are all included, reached through access panels where needed.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We don’t leave it behind.
Are you a BESCA Vent Hygiene Elite member?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 sit alongside that, and we’re fully insured.
What happens if you can’t reach some of it?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Will my insurer ask for a TR19 certificate?
Many policies require TR19 cleaning, and insurers often ask to see the certificate. An insurer may refuse or reduce a claim if there’s no evidence, so it’s worth checking your policy wording.
How long does a kitchen extract clean take?
That depends on the size of the system, the amount of grease and the number of access points. As a guide, it takes anything from a few hours to a full night, depending on the size of the system.
Honest limits
Some problems need a different service or another trade:
- Ductwork that is corroded, split or leaking (that’s for a ductwork contractor)
- Fat blocking the kitchen drains
- An undersized canopy or fan
Not sure which it is? You can call 0345 646 2711 or email us and we will tell you honestly before booking.

Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Clean grease off the canopy surfaces regularly
- Run the extract fan throughout cooking
- Refit filters properly after cleaning
- Clean the grease filters regularly between TR19 cleans
After cleaning, we re-test the same points we measured at the start, so you can see the difference in numbers as well as pictures. A TR19 certificate follows, issued through the BESCA Vent Hygiene Elite portal.
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.
