AHU cleaning for kitchens and businesses in Cookham
We clean air handling units for buildings in Cookham and across Windsor and Maidenhead, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you are dealing with air handling units never cleaned inside and drain trays holding standing water, we can help, from supply and extract fans, filter sections and drain trays onwards.
In a place like Cookham, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What staff can safely do
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
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.
Fixed quotes for AHU cleaning in Cookham
The survey tells us what the work involves. The main factors are:
- Whether we need access equipment or extra panels
- One-off work versus a regular cycle
- Parking and loading at the site
- Working hours and out-of-hours timing
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before we start.
Asking for a quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Where the site is and what kind of site it is
- How we’d reach plant on a roof or in a plant room
- A few general shots of the system
- Any previous report or certificate
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Common problems we fix in Cookham
Whatever surrounds a building in Cookham, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
Signs it’s time to call us include:
- Condensate trays that won’t empty
- Intake sections clogged with outdoor debris
- Fan sections that haven’t been cleaned in years
- Plant that needs cleaning after a refit
If you manage a school such as Cookham Rise Primary School, ventilation cleaning is best booked for the holidays.

Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time.

What happens on the day
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes from a few hours for a compact unit to a day or more for a large one. In a smaller place like Cookham, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Agree a time when the area can be out of use
