Ventilation duct cleaning in Greenhill
Ventilation duct cleaning is something we carry out for buildings in Greenhill and right across Greater London, from offices and schools to hospitals, care homes and shops. Every job begins with a survey and a fixed quote. Common call-outs are for poor airflow from the vents and duct runs that can’t be reached for cleaning, across toilet extract systems, general extract ductwork and hospitals and care homes.
Many London buildings have had their ventilation extended and altered through several fit-outs, leaving sections that are hard to reach and seldom cleaned. In Greenhill, as elsewhere, cleaning starts with an inspection of what’s there.
The sign-off is always in writing: a dated report with pictures of the work, 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.

What we do, step by step
The first job on site is protection: 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 a shift or two for a small system, longer for a whole building, and we clear up before we go. Night and weekend working is normal for us in London, and a site in Greenhill is no exception.
- First the system is surveyed, on site or from photos and drawings.
- Ducts are inspected at access points and the condition recorded.
- Floors and furniture are covered and the ventilation turned off.
- Debris is cleared from the duct runs, then grilles and diffusers are cleaned.
- A certificate and before and after photos follow, with anything not reached recorded.
Before we arrive
- Move anything stored near the system
- Make sure someone can let us in and lock up afterwards
- Let us know about parking and loading
How to get a quote
We do not publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then give you a fixed quote. To start, phone us on 0345 646 2711 or drop us a line.
Advice
What staff can safely do
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, alongside 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. The inside of ducts and units needs a specialist.
Ventilation duct cleaning around Greenhill
Food Standards Agency data includes about 12 schools, colleges and universities, about 58 hospitals, care homes and childcare premises and about 3 hotels and guest houses within 1.5 miles or so of the middle of Greenhill. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Getting kit to a London plant room usually means lifts, stairs and an agreed loading slot. Northwick Park Hospital is the nearest hospital, about 0.7 miles south-east of Greenhill. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Healthcare ventilation, from large hospitals like Northwick Park Hospital (about 0.7 miles south-east) to small clinics, depends on clean filters, coils and ducts. Workplaces around Harrow-on-the-Hill station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
Greenhill is about 1 mile north-east of Harrow, in Greater London. Whether your site is in the middle of Greenhill or further out, we cover ventilation duct cleaning for every kind of premises, from a single unit to a large public building. Our Greater London coverage runs to 764 places, Greenhill among them. London is in our area too, about 12 miles from Greenhill.

What’s near Greenhill
We work in commercial kitchens and buildings around Royal Oak pub, Northwick Park and Harrow High School, among other places. Greenhill has its own railway station: Harrow-on-the-Hill station. Other landmarks nearby include St. Anns (less than half a mile south-west) and Hilfield Castle (4.8 miles north). Open spaces near Greenhill include Masons Field and Northala Fields.
Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Larger estates can be phased building by building to keep disruption down.
Why deal with it now?
Smells, dust around grilles and stuffy rooms are signs the system needs attention. Acting early keeps the clean simpler. For a site in Greenhill, fitting the work in overnight now is far easier than closing at short notice later.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.

Common questions in Greenhill
Does London parking affect a job in Greenhill?
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, typically makes it simpler.
Can you come to Greenhill after we close?
Yes. We work evenings, overnight and at weekends. The work in Greenhill can fit around your hours. Tell us your opening hours when you ask for a quote.
Does the law say we must follow TR19?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and without records, many insurers may refuse or reduce a claim.
Can you set up regular visits?
Yes, of course. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.
Where does the waste go?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we are fully insured.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.
What should I send you?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
Different parts, different methods
Schools and colleges
We plan the work around the school calendar, with access agreed with the caretaker or site manager.
Hospitals and care homes
Hospitals and care homes are occupied day and night. The work is sequenced with staff to keep disruption down.
Common problems we fix in Greenhill
Even good filters let some dust through, and that fine dust settles along the supply ducts. Extract ducts collect whatever the rooms give off: dust, fibres and lint.
If you notice any of these, it’s worth a diagnosis:
- Odours carried round the building by the ducts
- Supply ducts with years of dust inside
- Extract ducts clogged with lint and dust
- Construction dust left in ducts after a refit
If you manage a school such as Saint Jerome Church of England Bilingual School, ventilation cleaning is best booked for the holidays.
Questions to ask before booking
- Whether a written report and pictures are included
- Whether the work can be done while the site is closed
- What happens if part of the system cannot be accessed
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor

Aftercare tips
After the visit, a few habits help the work last:
- Keep to the inspection interval in your report
- Flag any dust coming out of the vents
- Log every filter change
- Report leaks or damp near ceilings and risers
Share the report with whoever looks after the building’s maintenance, so the history stays together. Year on year, it shows how fast dust builds up.
Protect the system during building work by switching it off or covering the grilles.
