AHU cleaning in Cowden
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, once the unit has been shut down and isolated. If you are dealing with plant that has been serviced but not cleaned and blocked condensate drains and slimy trays, we can put it right, from supply and extract fans, dampers and louvres and heating and cooling coils onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

What happens on the day
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes one overnight shift for many single units, with bigger plant phased. If you can send photos, we can arrive in Cowden knowing what to expect.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- 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.
Preparing for the visit
- Have your last certificate or report to hand
- Let us know about parking and loading
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Advice
Other services in Cowden
Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
What affects the cost of AHU cleaning
Sites vary more than people expect. The main factors:
- One-off work versus a regular cycle
- The condition of the system
- Site rules, permits and inductions
- The scale of the work
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before we start.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- Your opening hours and when the area is out of use
- Any access panels or hatches you can see
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The site address and the type of premises

Your questions about AHU cleaning in Cowden
Will you come out to Cowden?
Yes. Villages and rural sites across the South East are part of our work, Cowden included. Let us know about access, parking and anything unusual about getting there when you book.
Can you come to Cowden after we close?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
What about areas you can’t get to?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
Will you repair the fan or motor?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
How often do AHUs need cleaning?
That is set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Aftercare tips
So the system stays in good health:
- Stick to the filter change plan
- Make sure condensate is draining away
- Make sure the unit’s access doors open easily
- File each AHU report in the maintenance log
The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
Why act early in Cowden
Tenants, auditors and owners may want proof that the air handling plant is kept clean. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. With notice, the visit to Cowden can be fitted around your bookings and events.
What you pay depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.

What the work involves, part by part

Before the fan is touched, the unit is shut down and made safe in agreement with the site.
