Greater London · Ventilation duct cleaning
Ventilation duct cleaning in Keston, Greater London
Ventilation duct cleaning across Keston and nearby, timed so the site keeps working and signed off in writing with pictures.

- Dusty supply ductwork that hasn’t been cleaned in years
- Blocked general extract ductwork
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
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.
Ventilation duct cleaning in Keston, done properly
Toilet, washroom and general extract ducts gather dust, fluff and debris. Supply ducts carry anything the filters miss. We clean both, keeping the work tidy and the building protected. We’re often asked to deal with rooms that feel airless when the system runs and ductwork never cleaned since it was installed, across toilet extract systems, offices and schools and general extract ductwork.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. For a building in Keston, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Leave it or put it right?
Dust in ducts does not go away on its own. The longer it’s left, the more there is to remove, and the more gets blown back into the rooms. Leaving it on a busy London site only adds to the work.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.

Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Ventilation duct cleaning around Keston
The FSA’s food hygiene register lists about 5 hospitals, care homes and childcare premises with registered kitchens or food service across Keston and its immediate surroundings (about a mile and a half). Busy, occupied buildings like these are where clean supply air matters most. Princess Royal University Hospital is the nearest hospital, about 1.1 miles east of Keston. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Getting kit to a London plant room normally means lifts, stairs and an agreed loading slot.
If you manage a school such as Keston Church of England Primary School, ventilation cleaning is best booked for the holidays.

The process
There’s very little for your team to do 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. Before any visit in Keston, we agree where the van can stop and how equipment reaches the system.
- First we check the layout and any past paperwork.
- Inspection points are chosen and the ducts examined.
- The work area is protected and the system switched off.
- Ducts, grilles and diffusers are cleaned and the debris taken away.
- We report on the work, listing any inaccessible sections and the next inspection date.
Preparing for the visit
- Move anything stored near the system
- Mention any locked doors, roof access or ceiling voids
- Find the previous report, if there is one

Advice
What the work involves, part by part
Hospitals and care homes
In care settings, keeping dust contained is a priority. We protect the work area and take everything away.
Grilles and diffusers
Dark streaks round a ceiling diffuser can be a sign of dirty supply air. The grilles are cleaned and the ducts behind inspected.
Signs you need ventilation duct cleaning in Keston
Ductwork is hidden above ceilings and in risers, so dust collects unseen. The grilles get a wipe, but what’s behind them doesn’t.
Any of these means the system needs a check-up:
- Ventilation that needs a TR19® Air inspection
- Poor airflow from the vents
- Grilles and diffusers streaked with dirt
- Supply ducts with years of dust inside
If you run a surgery, dental practice or care home near Keston, clean ventilation matters as much to you as to a hospital like Princess Royal University Hospital (about 1.1 miles east).

Questions from Keston
Can the work in Keston be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The work in Keston can fit around your hours. Just ring 0345 646 2711 or email us with your opening times and we will plan around them.
Does London parking affect a job in Keston?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Working overnight, as we often do in London, usually makes it simpler.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Do we get a certificate after the clean?
Yes. The certificate records the date and location of the work and the technician, along with pictures before and after.
Will we have to shut during the visit?
Not normally. We need the work area to ourselves while we are on site, so the visit goes in a quiet slot.
What does TR19 Air cover?
The two cover different systems: general ventilation for TR19® Air and kitchen extract for TR19® Grease. Under TR19® Air, inspection decides when cleaning is needed.
What about areas you can’t get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Who is the responsible person?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
