How we handle ductwork cleaning in Aldgate
The ductwork is where an extract clean is won or lost. Sections with no way in can go uncleaned for years. We open up every reachable section and record any we can’t reach, so you know exactly where you stand. The work covers access panels, bends and junctions and vertical risers, and the jobs we see most are grease leaking from duct joints and grease pooling at the foot of the riser.
Kitchens in Aldgate, like many across London, can share a building with flats or offices, with the duct running up through shared risers. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What staff can safely do
Day-to-day cleaning is something your team can do: 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.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Keeping the system healthy
Once we have finished, these simple steps help:
- Book the next clean before the recommended date
- Consider fitting panels where the report shows gaps
- Flag drips from the duct right away
- Do not block access panels with shelving or stock
After the clean, the same points are tested again, so the report shows the before and after figures. Photos of each section go alongside them.
Watch for warning signs between cleans: grease leaking from duct joints, smells, or a fan that sounds rough. A grease thickness test can confirm whether a spot clean is needed.
Ductwork cleaning in Aldgate: the local picture
There are about 2,474 restaurants, cafés and works canteens and about 892 takeaways in Aldgate and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. Behind every canopy among them is a run of ductwork that collects grease out of sight. Most London extract cleaning happens at night, after the last service. Aldgate sits within the area of London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
If you cook for passing trade around London Fenchurch Street station, the extract can be cleaned between your last and first customer. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; London Bridge Hospital is the nearest hospital to Aldgate, about 0.6 miles south-west.

What the work involves, part by part
Multi-storey and shared buildings
A duct that climbs several floors may be cleaned over more than one visit. We agree a sequence that suits the building, out of hours where possible.
Bends and transitions
Wherever the duct turns or changes size, grease builds up. The air slows and drops its load, so we clean these points carefully.
What happens on the day
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a few hours for a short run, longer for long runs and tall risers. Before any visit in Aldgate, we agree where the van can stop and how equipment reaches the system.
- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- The duct is signed off with readings, pictures and a next clean date.
Getting ready for the visit
- Agree a time when the area can be out of use
- Let us know about parking and loading
- Mention any locked doors, roof access or ceiling voids

FAQs for Aldgate
Can you clean school kitchen extracts in Aldgate during the holidays?

Who carries out food hygiene inspections in Aldgate?
Kitchens in Aldgate are inspected by the City of London Corporation’s environmental health officers. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Will I get a report after the ducts are cleaned?
When the duct is cleaned as part of a full TR19 clean, you get a TR19 certificate and a photo report. The report shows readings, photos and any sections we couldn’t reach.
Can you fit access panels in our ductwork?
Yes, extra panels can be fitted. It means more of the duct can be cleaned next time, and the report will show where they’re needed.
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, and the emergency line covers the rest.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Is Aldgate in your area?
Yes. Aldgate is part of the area we cover, within the South East and London area we cover.
When to call us in Aldgate
Air cools as it moves away from the canopy. Cooling air drops its grease onto the inside of the duct, which is why ducts go on gathering grease well beyond the filters.
What we are most often called out for:
- Ductwork that has never been cleaned
- Gaps where access panels were never fitted
- Smells of old cooking grease from the ductwork
- Thick deposits at the bottom of a vertical duct
A hall kitchen that only cooks for events, whether near St James Duke's Place or elsewhere in Aldgate, still needs its extract cleaned, just less often.
What your quote should include
- Whether the quote shows VAT
- Whether the price is fixed
- Whether inaccessible sections are listed on the report
- When the next visit should be, and why
What happens if it’s left?
Grease narrows the duct and slows the air. Less air moves, so heat and smoke stay in the kitchen while the fan strains, and grease may start to leak from joints. A busy site in Aldgate builds up dirt and wear quickly, so putting it off makes the eventual job larger.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

How we price ductwork cleaning
Before we fix a price, we need to know a few things. We look at:
- Access, including roofs, risers and ceiling voids
- Whether several sites go on one quote
- Where the site is and how we reach it
- The size of the system
What you pay depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before any work starts, so you know where you stand.
Helping us quote
When you call or email, it’s useful to have:
- Problems your staff have spotted
- The site address and the type of premises
- 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
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before we start.
