Ductwork cleaning for kitchens and businesses in Bell Green
The ductwork is where an extract clean is won or lost. Without enough access panels, long stretches can go years without being touched. We open up every reachable section and record any we cannot reach, so you know exactly where you stand. If you’re dealing with a duct clean needed for an insurer and stale grease odours from the duct, we can put it right, from multi-storey ducts, vertical risers and horizontal duct runs onwards.
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 Bell Green, that typically means a longer system to clean and more access panels to plan around.
The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Your questions about ductwork cleaning in Bell Green
Which fire service covers Bell Green?
Fire safety enforcement in Bell Green is handled by London Fire Brigade. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
What do you need to know about parking in Bell Green?
Tell us where a van can stop near your site in Bell Green, and about any building rules on loading. If the building has a loading slot system, we’ll book into it.
Do you offer emergency callouts?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
Is a quote from photos possible?
Typically, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. If pictures are not enough, we’ll survey first.
Are you fully insured?
Yes. Full insurance covers our work, and we have been trading since 2009.
How far ahead should we book?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
What shows that the ducts need a clean?
A grease thickness test gives the answer. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). A mean above 200 microns, or 500 microns at any point, means it’s due.
Common problems we fix in Bell Green
Ducts in Bell Green gather grease for the same reasons as ducts anywhere: daily cooking hours, the menu and the state of the filters. Under BESA guidance, the minimum interval is 3, 6 or 12 months, by daily cooking hours.
What we’re most often called out for:
- Grease leaking from duct joints
- A duct clean needed for an insurer
- Heavy grease at the base of a riser
- Ductwork that has never been cleaned
Bursars and site managers at schools such as Haseltine Primary School tend to book extract cleaning for when the kitchen is empty.
Before you book anyone
- Whether the whole system is included, or only the parts that are easy to reach
- What happens if part of the system cannot be accessed
- How VAT is shown on the quote
- Proof of accreditation you can verify
What happens if it’s left?
There’s no law that names TR19. The Fire Safety Order 2005 makes the responsible person assess and reduce fire risk, including the grease inside the extract ductwork. Choosing the date yourself beats having a fault choose it for you.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

What the work involves, part by part
Bends and transitions
The join where the canopy meets the duct is a common hotspot. We clean it from the canopy side or through a nearby panel.
Vertical risers
Risers carry the extract up through the building to the roof. Grease collects on the walls and at the foot of the riser, which is one of the points we test.
Staff cleaning versus specialist work
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, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Kitchen extracts in Bell Green
Food Standards Agency records include about 38 pubs, bars and clubs and about 4 hotels and guest houses across Bell Green and its immediate surroundings (about a mile and a half). Any of them serving cooked food has an extract to keep clean, from canopy to discharge. London Fire Brigade covers Bell Green. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Night work suits London kitchens, and roads and loading bays tend to be quieter too.
Healthcare kitchens, like those at hospitals such as St Christopher's Hospice (about 1.2 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands. Where a hall near St Michael's and All Angels, or anywhere in Bell Green, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

What happens on the day
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes anything from a few hours to several visits, depending on the length of duct, and we clear up before we go. Before any visit in Bell Green, we agree where the van can stop and how equipment reaches the system.
- We start by working out how the duct runs and where it can be opened.
- We measure grease thickness at set points before cleaning.
- Through the access panels, thick grease is removed by hand first.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- Readings and pictures are repeated and any section we couldn’t reach is recorded.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Allow time for equipment near the work to be turned off and cool down
- Find the previous report, if there is one
How to get a quote
Quotes are quick. Call or email with a few details and you will usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
