How we price AHU cleaning
The quote reflects the site in front of us. We consider:
- Site requirements such as sign-in and permits
- How easy every part is to reach
- The number of sites or systems
- The times the site is available
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before any work starts, so there are no surprises.
What to send for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- The postcode and the type of business
- Detail shots of panels, filters and grilles
- Your opening hours and when the area is out of use
- Any symptoms, from odd noises to smells or leaks
The quickest way to a quote is to send photos: 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 we can price many jobs without a visit.
AHU cleaning in Owlsmoor, done properly
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. The work covers supply and extract fans, filter sections and internal panels, and common reasons people get in touch are blocked condensate drains and slimy trays and dirty fans and fan housings.
In a place like Owlsmoor, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.
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. It shows what was done and what, if anything, couldn’t be reached.

Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare in Owlsmoor and across Bracknell Forest. Work can be phased by floor, building or site to keep disruption down.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
What the work involves, part by part
Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so you can decide on any repairs.
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.

Ventilation in Owlsmoor buildings
Going by the FSA’s register, there are about 7 schools, colleges and universities and about 16 hospitals, care homes and childcare premises serving food across Owlsmoor and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. At about 31 miles from central London, Owlsmoor sits well inside the area we cover. Visits are booked around your hours, evenings and weekends included. About 2 miles north of Owlsmoor is Pinewood Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
School buildings such as Owlsmoor Primary School are typically done in the holidays, so classrooms aren’t disturbed.

What we do, step by step
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. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes anything from half a day for one small unit to several shifts for a plant room full of them. Evenings, weekends or a closed day all work for a site in a place like Owlsmoor.
- We agree a shutdown window that suits the building.
- We take before photos 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.
- We take after photos and issue the certificate and report.
Getting ready for the visit
- Tell us where we can park and unload
- Have your last certificate or report to hand
- Plan for cooking equipment or plant to be off before we arrive

Your questions about AHU cleaning in Owlsmoor
Can the work in Owlsmoor be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Owlsmoor keeps running as normal. Tell us your opening hours when you ask for a quote.
Do you cover smaller places like Owlsmoor?
Yes. Owlsmoor is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Which sectors do you work in?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
Do you do ventilation duct cleaning too?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can survey both on the same visit.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What does AHU cleaning cost?
We do not publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before we start.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
Can you price the work without visiting?
Normally, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. If photos are not enough, we will survey first.
Why it’s worth doing now in Owlsmoor
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. When a site near Owlsmoor shuts unexpectedly, the people who rely on it notice at once.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, call 0345 646 2711, or email photos for straight advice and a fixed quote.

Between visits
To keep the system working properly between visits:
- Flag stale or damp smells in the supply air
- Plan the next inspection before the last report gets filed away
- Keep filter changes on time and recorded
- Report water on the plant room floor
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Common problems we fix in Owlsmoor
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.
Keep an eye out for these warning signs:
- Odours coming through the supply air
- Intake sections clogged with outdoor debris
- Plant that has been serviced but not cleaned
- Condensate trays that will not empty
If you run a surgery, dental practice or care home near Owlsmoor, clean ventilation matters as much to you as to a hospital like Pinewood Hospital (about 2 miles north).
What your quote should include
- Whether they’re fully insured
- Whether they recommend a next date
- How areas they can’t reach will be recorded
- When they can work, and whether that is outside your opening hours
