Ductwork cleaning around Bentley Heath
Look up Bentley Heath on the FSA’s food hygiene register and you’ll find about 44 restaurants, cafés and canteens and about 26 sandwich bars and takeaways across Bentley Heath and its immediate surroundings (about a mile and a half). The duct above a busy canopy coats itself in grease long before anyone sees it. Food hygiene inspections in Bentley Heath are the job of Hertsmere council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected.
For schools such as Pope Paul Catholic Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. Where a hall near Church of King Charles and the Martyr, or anywhere in Bentley Heath, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Ductwork cleaning for kitchens and businesses in Bentley Heath
Once air leaves the canopy, it travels through ductwork that most people never see. Grease settles along every metre of it, and that is where a kitchen fire can travel. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. We’re often asked to deal with years of grease along the duct floor and high readings at a recent grease test, on multi-storey ducts, vertical risers and attenuators.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, and the duct may run up through several floors before it discharges at the roof. For a kitchen in Bentley Heath, that usually means a longer system to clean and more access panels to plan around.
Good records are part of the job. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Your questions about ductwork cleaning in Bentley Heath
Which fire and rescue service is responsible for Bentley Heath?
Bentley Heath is in the area of London Fire Brigade. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
How do you handle parking and loading in Bentley Heath?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Working overnight, as we often do in London, normally makes it simpler.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
What’s the cleaning interval for extract ductwork?
It follows the same interval as the whole extract, ranging from 3-monthly to 12-monthly. Readings tell you if it needs to be more often.
How long does it take to clean extract ducts?
Duct length, access and grease levels all affect it. Typically it takes from a few hours to more than one visit, depending on duct length and access.
How do you clean inside the ductwork?
We survey the route, test the grease, then open the access panels. Each run and riser is scraped and degreased, then the readings are repeated.
Common problems we fix in Bentley Heath
Ducts in Bentley Heath gather grease for the same reasons as ducts anywhere: daily cooking hours, the menu and the state of the filters. BESA guidance sets minimum intervals of 3, 6 or 12 months depending on daily use.
Common reasons sites call us are:
- Duct runs that cannot be reached
- Smells of old cooking grease from the ductwork
- Grease seeping out of the duct seams
- Ductwork that has never been cleaned
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Barnet General Hospital is the nearest hospital to Bentley Heath, about 2.4 miles south.
Questions to ask before booking
- How they set the interval to the next visit
- Whether the quote is based on a survey or photos
- Whether a written report and pictures are included
- Exactly which parts of the system are covered
The process
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. We fit London jobs around the building rather than the other way round, so a visit in Bentley Heath is typically out of hours.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- Panels are closed, readings and pictures repeated, and unreachable sections recorded.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Move anything stored near the system
- Name a contact who can let us in at the agreed time
Ask for a quote
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To get going, phone us on 0345 646 2711 or email us.
Advice
For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Facilities teams in offices, schools and healthcare sites book us too in Bentley Heath and across Greater London. Larger estates can be phased building by building around the people who use them.
What the work involves, part by part
Attenuators and discharge
Near the discharge, the air has cooled the most, which can mean heavier deposits. We include it in the clean and the readings.
Access panels
Panels have to seal properly once they’re closed, so grease and air stay inside the duct. We will tell you if any panel needs replacing.
Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Run the extract fan throughout service
- Consider fitting panels where the report shows gaps
- Diarise the next duct clean
- Have the grease measured if cooking hours go up
You’ll have a recommended date for the next clean, based on the readings and your daily cooking hours, in line with BESA guidance.
Extra access panels mean more of the duct gets cleaned each time. It does not stop grease forming, but it stops it building unseen.

How we price ductwork cleaning
We do not publish a price list, because sites vary so much. The quote depends on:
- Site requirements such as sign-in and permits
- The number of sites or systems
- When the work can happen, such as evenings, overnight or weekends
- The scale of the work
The cost depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- The times we could work without disrupting the site
- Your last certificate, test record or report
- The site address and the type of premises
- Problems your staff have spotted
The quickest way to a quote is to send photos: 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.
In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
