Air handling unit cleaning in Headstone, Greater London
AHU cleaning in Headstone from ventilation hygiene specialists trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Dirty filters cutting the airflow
- Debris and leaves in the fresh air intake
- Drain trays holding standing water
Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
AHU cleaning for kitchens and businesses in Headstone
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. If you have plant that needs cleaning after a refit and odours coming through the supply air, we can put it right, from drain trays, supply and extract fans and dampers and louvres onwards.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Headstone is usually planned out of hours. Parking and loading are agreed with the building in advance.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Common problems we fix in Headstone
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and the finer material travels on.
Most sites get in touch when they notice something like this:
- Blocked condensate drains and slimy trays
- Air handling units with blocked filters
- Dirty coils holding back the airflow
- Odours coming through the supply air
Workplaces around Headstone Lane station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

Why it’s worth doing now in Headstone
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before we start.

Part by part
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that won’t bend or flatten the fins.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.

Going by the FSA’s register, there are about 5 schools, colleges and universities and about 35 caring premises (care homes, nurseries and hospitals) serving food in and around Headstone, up to about a mile and a half out. Busy, occupied buildings like these are where clean supply air matters most. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first.

Aftercare tips
Here’s the after-treatment advice, short and simple:
- Change filters on schedule and log each change
- Make sure condensate is draining away
- Plan the next inspection before the last report gets filed away
- Make sure the unit’s access doors open easily
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
What happens on the day
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, while signing off means the written report and photos. The middle part takes longest, which takes half a day to a full day per unit, with large plant planned over several shifts. In Headstone, as across London, we normally work overnight or at weekends and hand the site back ready to open.
- 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.
- We take after pictures and issue the certificate and report.
Before we arrive
- Agree a time when the area can be out of use
- Mention any sign-in, permit or induction we need
- Let us know about parking and loading
Getting a quote
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. Add the site type and your opening hours, and we can price many jobs without a visit.
