How we handle AHU cleaning in Cookley Green
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. Typical jobs include filters that are clogged or overdue and rooms that smell stuffy when the system runs, on internal panels, filter sections and drain trays.
For a building in or near Cookley Green, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Managing agents and facilities teams in Cookley Green
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 on a regular cycle.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.

What we work on in Cookley Green
- Supply and extract fans
- Heating and cooling coils
- Filter sections
- Drain trays
- Dampers and louvres
- Internal panels
Different parts, different methods
Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
Aftercare tips
Looking after the system between visits is straightforward, and it helps at the next visit:
- Note any water around the unit or leaks below it
- Look at the condensate drain whenever the unit is serviced
- Do not store bins or materials near the intake
- Make sure the unit’s access doors open easily
Restart the unit with your site team or maintenance contractor once we’ve finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
How the visit works
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes a single shift for a typical unit, longer for large or heavily soiled ones, and the area is cleaned down before we leave. Somewhere as small as Cookley Green, the date and timings are agreed with you well before the day.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Mention any sign-in, permit or induction we need
- Tell us the best time to work, such as after service or at a weekend

Advice
Cookley Green: your questions answered
Can you work in Cookley Green outside opening hours?
Yes, nights and weekends are routine for us. That way a site in Cookley Green doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Will you come out to Cookley Green?
Yes. Cookley Green is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you offer maintenance contracts?
Yes, of course. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Will you repair the fan or motor?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report for your maintenance team to follow up.
Do you have insurance?
Yes, we are fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
What happens if you cannot reach some of it?
They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We don’t leave it behind.

What else we do in Cookley Green
Staff cleaning versus specialist work
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. Reaching it takes a specialist with the right equipment.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Signs you need AHU cleaning in Cookley Green
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that’s where slime and odours start.
Any of these means the system needs a check-up:
- Condensate trays that won’t empty
- Units needing a clean before a new tenant or handover
- Intake sections clogged with outdoor debris
- Odours coming through the supply air
An inspection comes first for any ventilation job around Cookley Green, so the cleaning matches what’s there.
