What we’re called out for in Berrylands
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that’s the air they breathe for hours on end.
Common reasons sites call us are:
- Dirty filters cutting the airflow
- Intake sections clogged with outdoor debris
- Drain trays holding standing water
- Units needing a clean before a new tenant or handover
Wherever a school like Christ Church CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

How we handle AHU cleaning in Berrylands
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. If you are dealing with stale or musty smells from the ventilation and dirty fans and fan housings, we can help, from drain trays, dampers and louvres and internal panels onwards.
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. In a building in Berrylands, dust and debris build up in the units and ductwork over time.
Think of the report as the system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Around Berrylands
Around Berrylands, our work takes us to kitchens and buildings near Beverley Park, Coronation Hall pub and Kingston School of Art. Berrylands has its own railway station: Berrylands station. A little further out are Tolworth Hospital (1.1 miles south) and Bentall Centre (1.5 miles north-west). For a walk, there’s Kingston Hill Road area and The Lake.
Multi-site and managed buildings
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. 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.
In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
What a clean won’t put right
In fairness, some problems need a different fix:
- Problems with the unit’s controls or sensors
- Breakdowns that need a mechanical engineer
- The supply and extract ducts, quoted separately
Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we’ll tell you honestly.

Questions from Berrylands
Can you work in Berrylands outside opening hours?
Yes, we can come after you close and finish before you open. That way a site in Berrylands doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Can a school’s ventilation in Berrylands be done out of term time?
Yes, holiday work suits schools best. Food Standards Agency records list about 45 schools, colleges and universities with registered kitchens within about a mile and a half of Berrylands. Just call us on 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
What happens if you cannot reach some of it?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
Which kinds of sites do you work on?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Do you repair air handling units?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
Can you price the work without visiting?
Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.
Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Change filters on schedule and log each change
- Do not store bins or materials near the intake
- Report water on the plant room floor
- Store the TR19 paperwork where auditors can find it
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. They belong in the plant or maintenance log.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
What we do, step by step
Each visit runs to the same pattern: protect the area, make the system safe, do the work, tidy up and hand over the paperwork. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Security desks and permits-to-work are routine in London, so let us know what your building in Berrylands needs from us.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about permits to work or site inductions
- Arrange a key holder or contact on site

Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
