AHU cleaning in Hackbridge, done properly
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. The work covers supply and extract fans, heating and cooling coils and drain trays, and people most often call us about dust-coated heating and cooling coils and condensate trays that won’t empty.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in Hackbridge is often done in the evening or at weekends. Loading and parking are planned with the building first.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Common problems we fix in Hackbridge
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Most sites get in touch when they notice something like this:
- Air handling units due a clean after building work
- Plant that has been serviced but not cleaned
- Blocked condensate drains and slimy trays
- Dirty filters cutting the airflow
Healthcare ventilation, from large hospitals like Wilson Hospital (about 0.5 miles south-west) to small clinics, depends on clean filters, coils and ducts.
What your quote should include

- When they can work, and whether that is outside your opening hours
What the work involves, part by part
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with photos so repairs can be planned.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Your questions about AHU cleaning in Hackbridge
Can you work in Hackbridge outside opening hours?
Yes, we can come after you close and finish before you open. The work in Hackbridge can fit around your hours. When you ring 0345 646 2711, or send details by email, mention when the site is quiet.
Can ventilation in schools around Hackbridge be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 30 schools and colleges with food registrations within roughly a mile and a half of Hackbridge. Send us your term dates when you phone us on 0345 646 2711, or email photos, and we will fit the work in.
How much does AHU cleaning cost?
It depends on the site, so we quote each one individually. For a quote, ring 0345 646 2711, or email photos with the site type, opening hours and a few pictures.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Do you repair air handling units?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
What happens if you cannot reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
What should I send you?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
Are you accredited?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
Multi-site and managed buildings
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, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
When it’s something else
Before you book, it helps to know what’s not included:
- Coils that are corroded or leaking and need replacing
- Airflow problems caused by the system’s design
- The supply and extract ducts, quoted separately
If you’re not sure, just call us on 0345 646 2711, or email photos and we’ll give you a straight answer.
Parts of the system we cover
- Heating and cooling coils
- Supply and extract fans
- Drain trays
- Dampers and louvres
- Internal panels
- Filter sections
What affects the cost of AHU cleaning
We quote each job individually. This is what makes a difference:
- Whether we need access equipment or extra panels
- Any permits to work or inductions
- When the work can happen, such as evenings, overnight or weekends
- Whether several sites go on one quote
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.
Helping us quote
We can often survey from pictures. Try to include:
- Photos showing the whole system and its surroundings
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- How we’d reach plant on a roof or in a plant room
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
What AHU cleaning looks like in Hackbridge
The FSA’s food hygiene register lists about 30 schools, colleges and universities and about 41 hospitals, care homes and childcare premises with registered kitchens or food service within 1.5 miles or so of the middle of Hackbridge. Busy, occupied buildings like these are where clean supply air matters most. Wilson Hospital is the nearest hospital, about 0.5 miles south-west of Hackbridge. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. Getting kit to a London plant room usually means lifts, stairs and an agreed loading slot.
Classrooms and halls at schools such as St Thomas of Canterbury Catholic Primary School are easiest to work in when pupils are away. If you run an office near Mitcham Eastfields station, its supply ductwork can gather dust for years before anyone looks inside.

What happens on the day
A visit follows the same order every time: protect the area, isolate whatever needs isolating, do the work, clear away and leave you the report. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. In Hackbridge, as across London, we typically work overnight or at weekends and hand the site back ready to open.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Clear the space around the work
- Make sure someone can let us in and lock up afterwards
