Ductwork cleaning for kitchens and businesses in Harlington
The ductwork is where an extract clean is won or lost. Without enough access panels, long stretches can go years without being touched. Each section we can reach is cleaned, and any we cannot is written down, so you know exactly where you stand. We are often asked to deal with fat dripping from the ductwork and gaps where access panels were never fitted, across bends and junctions, vertical risers and horizontal duct runs.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in Harlington, that typically means a longer system to clean and more access panels to plan around.
Every visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Fixed quotes for ductwork cleaning in Harlington
Your quote is based on your site. We consider:
- Whether it’s a one-off visit or part of a schedule
- The size of the system
- Site rules, permits and inductions
- Parking and loading at the site
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before any work starts.
What to send for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your last certificate, test record or report
- The postcode and the type of business
- Photos showing the whole system and its surroundings
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
What happens on the day
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before any work starts, and floors and nearby surfaces are sheeted. On site, it takes from a few hours to more than one visit, depending on duct length and access. Most London sites can’t stop for the day, so work in Harlington is normally done overnight, early in the morning or at weekends.
- We map the duct route and check where the access panels are.
- We measure grease thickness at set points before cleaning.
- We open the panels and scrape out the heaviest grease.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- Post-clean readings and pictures go into the report, with any unreachable section listed.
How to prepare
- Let us know about permits to work or site inductions
- Tell us the best time to work, such as after service or at a weekend
- Have your last certificate or report to hand

Advice
Staff cleaning versus specialist work
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Harlington: your questions answered
Can you come to Harlington after we close?
Yes, evening, overnight and weekend work is normal for us. The work in Harlington can fit around your hours. Tell us your opening hours when you ask for a quote.
How do you handle parking and loading in Harlington?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Night visits tend to make loading easier on London streets.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
What paperwork do you give after a duct clean?
Every clean comes with a photo report, and a full TR19 clean also comes with a certificate issued through the BESCA Vent Hygiene Elite portal. File them with the fire risk assessment.
What does ductwork cleaning cost?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before work begins.
Is there a survey before the work?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. Then you get a fixed quote.
Is TR19 cleaning required by law?
Not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurers ask for proof of cleaning to it. The law behind it is the Fire Safety Order 2005, which applies in England and Wales.
Do you need ductwork cleaning in Harlington?
Grease settles fastest where the air slows down. Long horizontal runs, bends, changes in size and the foot of a riser all collect more, and those are the points we pay most attention to.
These are the problems we see most often:
- Grease leaking from duct joints
- Smells of old cooking grease from the ductwork
- An insurer asking for TR19 evidence
- A grease test showing the duct is overdue
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Osterley House is about 3.6 miles east), access may need planning.

Part by part
Horizontal duct runs
Flat runs of duct link the canopy to the riser or the outside wall. They collect grease as the air cools and slows, and we clean them section by section through access panels.
Multi-storey and shared buildings
A duct that climbs several floors may be cleaned over more than one visit. Visits are planned around the building’s hours, out of hours where possible.
When something else is needed
We’d rather tell you now than book work that won’t help, so here are the limits:
- A damper stuck open in the duct
- A failed fan motor at the end of the duct (a fan repair job)
- Duct sections that need replacing
If you are not sure, just give us a ring on 0345 646 2711, or send details by email and we will give you a straight answer before you book.

Grease, kitchens and Harlington
Food Standards Agency data counts about 66 restaurants, cafés and canteens and about 23 sandwich bars and takeaways within 1.5 miles or so of the middle of Harlington. The duct above a busy canopy coats itself in grease long before anyone sees it. Environmental health officers from Hillingdon council inspect food businesses in Harlington. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. Fire safety in Harlington falls to London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Volunteers running a hall kitchen near Church of St Peter and St Paul, or anywhere in Harlington, may not know when the extract was last cleaned, and a grease test settles it. For schools such as William Byrd Primary Academy, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.
