AHU cleaning for kitchens and businesses in North Sheen
Where a building in North Sheen has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. If you’re dealing with debris and leaves in the fresh air intake and air handling units never cleaned inside, we can put it right, from heating and cooling coils, supply and extract fans and filter sections onwards.
London buildings tend to keep their plant on the roof or below ground, so work in North Sheen is often done in the evening or at weekends. Loading and parking are planned with the building first.
The sign-off is always in writing: 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.

Keeping the system healthy
To keep the system working properly between visits:
- Report water on the plant room floor
- Keep inspection doors on the unit in good order
- Make sure condensate is draining away
- Report musty smells from the vents straight away
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.

What staff can safely do
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
AHU cleaning in North Sheen: local notes
The FSA’s food hygiene register lists about 29 schools, colleges and universities, about 43 caring premises (care homes, nurseries and hospitals) and about 13 hotels and B&Bs with registered kitchens or food service in North Sheen and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. In London, ventilation plant is often on the roof or below ground, so the work is usually done out of hours. Barnes Hospital is the nearest hospital, about 1.1 miles south-east of North Sheen. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
If you run an office near Kew Gardens station, its supply ductwork can gather dust for years before anyone looks inside. Hospitals such as Barnes Hospital (about 1.1 miles south-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near North Sheen are no different. Classrooms and halls at schools such as Kew Riverside Primary School are easiest to work in when pupils are away.

Common questions in North Sheen
Can you clean school ventilation in North Sheen during the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 29 schools, colleges and universities with registered kitchens within about a mile and a half of North Sheen. Just ring 0345 646 2711 or send us an email with your term dates and we will plan around them.
Can you come to North Sheen after we close?
Yes, evening, overnight and weekend work is normal for us. That way a site in North Sheen doesn’t have to lose a day’s trading. When you give us a ring on 0345 646 2711 or send us an email, mention when the site is quiet.
Is there a survey before the work?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Do you have insurance?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with pictures where it helps.
How long will the unit be out of action?
Expect it to take half a day to a full day per unit, with large plant planned over several shifts. The unit’s size and condition make the biggest difference, and we will confirm the time when we quote.
What’s included in an AHU clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
What do you need from me for a quote?
Some pictures and a quick description of the system, with the address and opening hours. We’ll ask for anything else we need.
What affects the quote in North Sheen
The diagnosis comes before the price. We look at:
- The number of sites or systems
- Whether we need access equipment or extra panels
- The condition of the system
- 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 give you a fixed price before any work starts.
What we need to know
To help us quote quickly, please include:
- Detail shots of panels, filters and grilles
- Problems your staff have spotted
- Wide pictures of the system and the area around it
- The site address and the type of premises
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
Why deal with it now?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, particularly where damp has made it stick. Planning ahead in North Sheen lets you pick a quiet night rather than lose a busy one.
You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, call us on 0345 646 2711 or email us, and we’ll explain what it covers.

What AHU cleaning can’t fix
We will not sell you work that does not address the problem, so these are the things it won’t cover:
- Mechanical faults with motors, belts or bearings
- Problems with the unit’s controls or sensors
- Ventilation that was badly designed in the first place
If you’re not sure, just call us on 0345 646 2711 or send us an email and we’ll give you a straight answer before you book.
Parts of the system we cover
- Filter sections
- Dampers and louvres
- Supply and extract fans
- Internal panels
- Heating and cooling coils
- Drain trays
Part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
How it works
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes half a day to a full day per unit, with large plant planned over several shifts. In North Sheen, as across London, we usually work overnight or at weekends and hand the site back ready to open.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Agree a time when the area can be out of use
- Tell us where we can park and unload
Ask for a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.
