AHU cleaning for kitchens and businesses in Kenton
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so the report shows exactly what was done. If you have filters that are clogged or overdue and units that have only ever had filter changes, we can help, from internal panels, supply and extract fans and dampers and louvres 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. For a building in Kenton, dust settles in the units and ducts year after year.
The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What the work involves, part by part
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Why act early in Kenton
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Every month a London system goes without attention adds to what has to be done later.
The cost depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before any work starts, so there are no surprises.

Your questions about AHU cleaning in Kenton
Do you clean school ventilation in Kenton in the holidays?
Yes, holiday work suits schools best. There are about 17 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Kenton. Send us your term dates when you ring 0345 646 2711 or send us an email, and we will fit the work in.
Do you work at weekends in Kenton?
Yes, evening, overnight and weekend work is normal for us. The work in Kenton can fit around your hours. Let us know the hours you are closed and we’ll book within them.
What do you do with what you remove?
It leaves the site with us at the end of the visit. While we work, it’s kept contained to keep the area clean.
Can you price the work without visiting?
Typically, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote normally follows within one working day. If pictures are not enough, we will survey first.
How much does AHU cleaning cost in Kenton?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before any work starts.
Is Kenton in your area?
Yes. Kenton is part of the area we cover, within the South East and London area we cover.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. We’ll tell you after the survey whether the ducts need it.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
How it works
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, and that takes half a day to a full day per unit, with large plant planned over several shifts. Most London sites can’t stop for the day, so work in Kenton is typically done overnight, early in the morning or at weekends.
- We survey the unit from photos or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Make sure someone can let us in and lock up afterwards
- Move anything stored near the system
- Make sure equipment near the work can be switched off and left to cool

Advice
What staff can safely do
Staff cleaning does not 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.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

Keeping the system healthy
Aftercare is simple, and it helps at the next visit:
- Do not store bins or materials near the intake
- Store the TR19 paperwork where auditors can find it
- Note any water around the unit or leaks below it
- Plan the next inspection before the last report gets filed away
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
Common problems we fix in Kenton
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Signs it’s time to call us include:
- Dust-coated heating and cooling coils
- Blocked condensate drains and slimy trays
- Fan sections that haven’t been cleaned in years
- Plant that needs cleaning after a refit
If you manage shops or offices close to Kenton station, a TR19® Air inspection shows whether the ductwork needs cleaning.

Honest limits
A few issues sit outside what this work can do:
- Damaged coils beyond cleaning
- Ductwork downstream of the unit, which is a separate clean
- Ventilation that was badly designed in the first place
