AHU cleaning in Stansted
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. If you’re dealing with dirty fans and fan housings and plant that needs cleaning after a refit, we can put it right, from heating and cooling coils, internal panels and dampers and louvres onwards.
Somewhere as small as Stansted, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

How the job changes from site to site
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins aren’t damaged.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
What a clean won’t put right
It’s worth knowing the limits before booking:
- A system that’s undersized for the building
- Breakdowns that need a mechanical engineer
- Coils that are corroded or leaking and need replacing
If in doubt, call us on 0345 646 2711, or send details by email and we will say what we think.
Parts of the system we cover
- Filter sections
- Dampers and louvres

How we price AHU cleaning
Your quote is based on your site. We consider:
- Whether several sites go on one quote
- The scale of the work
- Whether we need access equipment or extra panels
- When the work can happen, such as evenings, overnight or weekends
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
Helping us quote
What to send for a quote:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- When the site is open and when it’s quiet
- The site address and the type of premises
- Close-ups of filters, grilles, hatches or access panels

What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. 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.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Do you need AHU cleaning in Stansted?
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.
Look out for these warning signs:
- Air handling units due a clean after building work
- Blocked condensate drains and slimy trays
- Dirty fans and fan housings
- Intake sections clogged with outdoor debris
Hospitals such as Sevenoaks Hospital (about 5.5 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Stansted are no different.
What to look for in a quote
- Exactly which parts of the system are covered
- Whether a written report and photos are included
- Whether they’re fully insured
- Whether VAT is included

Sevenoaks Hospital is the nearest hospital, about 5.5 miles south-west of Stansted. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Stansted is about 20 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours.
For schools like Wrotham School, the holidays are the usual time to inspect and clean ventilation.

Near you in Stansted
Around Stansted, our work takes us to kitchens and buildings near Trosley Country Park. For rail, the closest station is Borough Green & Wrotham station, roughly 2.9 miles south. A little further out are Sevenoaks Hospital (5.5 miles south-west) and Ightham Court (2.8 miles south).
The process
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before work begins, and floors and nearby surfaces are sheeted. The work itself takes from a few hours for a compact unit to a day or more for a large one. We agree a date with you, plan the drive to Stansted and turn up when the site is quiet.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Tell us the best time to work, such as after service or at a weekend
- Mention any sign-in, permit or induction we need

Related advice
Stansted questions
Can you come to Stansted after we close?
Yes, we can come after you close and finish before you open. It means the site in Stansted keeps running as normal. Just give us a ring on 0345 646 2711 or use the quote form with your opening times and we will plan around them.
Will you come out to Stansted?
Yes. Villages and rural sites across the South East are part of our work, Stansted included. A survey first, from pictures or a visit, means we arrive with the right kit.
How often should an air handling unit be cleaned?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and the report recommends a next date.
Do you work with multi-site operators?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Each site gets its own report and photos.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Will you repair the fan or motor?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded for your maintenance team to follow up.
Will the ventilation be off while you clean?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
Is a quote from pictures possible?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
Looking after it afterwards
So the system stays in good health:
- Stick to the filter change plan
- Look at the condensate drain whenever the unit is serviced
- Make sure the unit’s access doors open easily
- Keep the certificate and photo report with the plant records
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
