Staff cleaning versus specialist work
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Ductwork cleaning in Harrow, done properly
Ductwork in Harrow is cleaned the same thorough way as everywhere else we work: we test the grease first, remove thick deposits by hand and degrease what’s left. Post-clean readings and pictures complete the record. Typical jobs include heavy grease at the base of a riser and hardened, baked-on grease in long horizontal runs, across access panels, attenuators and horizontal duct runs.
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 Harrow, that typically means a longer system to clean and more access panels to plan around.
Good records are part of the job. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

What happens if it’s left?
There’s no law that names TR19. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and grease in the duct is part of that. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
The cost depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before any work starts, so there are no surprises.

The process
Your staff do not need to do much 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. Security desks and permits-to-work are routine in London, so let us know what your building in Harrow needs from us.
- We map the duct route and check where the access panels are.
- Grease readings are taken at set points along the duct.
- Access panels are opened and heavy deposits scraped out by hand.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- We test again, take pictures and note any part that couldn’t be reached.
Getting ready for the visit
- Let us know when the site is closed or quiet
- Clear loose items from the work area
- Mention any sign-in, permit or induction we need

Signs you need ductwork cleaning in Harrow
Damaged or poorly fitted filters let more grease into the duct. The duct then takes grease that the filters should have stopped, and build-up speeds up.
Most sites get in touch after spotting something like this:
- Proof of duct cleaning for the insurer
- A rancid smell from the extract duct
- Hardened, baked-on grease in long horizontal runs
- Thick deposits at the bottom of a vertical duct
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Harrow is Clementine Churchill Hospital, about 1 mile south-east.
Questions to ask before booking
- Whether they recommend a next date
- Whether the work can be done while the site is closed
- Whether VAT is included
- Whether the figure could change on the day
What affects the quote in Harrow
A fixed price needs a few facts first. We check:
- How easy every part is to reach
- Where the site is and how we reach it
- The size of the system
- How many systems or sites are involved
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 give you a fixed price before we start.
What to send for a quote
To help us quote quickly, please include:
- The postcode and the type of business
- The times we could work without disrupting the site
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Once you have those, call us on 0345 646 2711 or email us.
Your questions about ductwork cleaning in Harrow
Can parking be tricky for a job in Harrow?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, usually makes it simpler.
Who enforces fire safety at workplaces in Harrow?
That is 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.
Will the duct clean disrupt the kitchen?
The duct is cleaned out of hours, evenings, overnight or at weekends. The extract and cooking equipment need to be off.
Can we book visits on a schedule?
Yes, of course. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
Do you survey before quoting?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. A fixed quote follows.
Do you install duct access panels?
Yes, we fit access panels where the duct needs them. It means more of the duct can be cleaned next time, and the report will show where they’re needed.
Is a quote from photos possible?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
Are you fully insured?
Yes, we are fully insured. We also hold CHAS and SafeContractor, for sites that check contractor safety.
When something else is needed
A few issues sit outside what this work can do:
- Parts of the duct with no way in
- A duct that’s too small or badly routed for the kitchen (a design issue)
- Fire dampers that don’t close (they need testing and remedials)
If in doubt, phone us on 0345 646 2711 or drop us a line and we will say what we think.

Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
We also work for facilities teams across offices, schools and healthcare across Greater London. Larger estates can be phased building by building around the people who use them.
Grease, kitchens and Harrow
There are about 280 restaurants, cafés and works canteens and about 127 sandwich bars and takeaways in and around Harrow, up to about a mile and a half out, according to the Food Standards Agency’s register. Where they cook under a canopy, grease does not stop at the filters: it settles along the duct and up the riser. Kitchens in Harrow get their food hygiene inspections from Harrow council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Most London extract cleaning happens at night, after the last service.
Term dates shape school work: for a school like Whitmore High School, an extract clean fits neatly into a half-term or summer break. A hall kitchen that only cooks for events, whether near Church of St Peter or elsewhere in Harrow, still needs its extract cleaned, just less often.
