Air handling unit cleaning in Marlow Common, Buckinghamshire

How we handle AHU cleaning in Marlow Common
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after pictures in a report. The work covers drain trays, internal panels and dampers and louvres, and common reasons people get in touch are coils clogged with dust and debris and plant that needs cleaning after a refit.
Work in a small place like Marlow Common starts with agreeing access and timings.
Good records are part of the job. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

AHU cleaning in Marlow Common: local notes
Food Standards Agency data includes about 6 schools, colleges and universities and about 6 care, childcare and hospital premises within roughly a mile and a half of the centre of Marlow Common. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. We cover Marlow Common, about 31 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours. Marlow Community Hospital is the nearest hospital, about 1.7 miles east of Marlow Common. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
If you run a surgery, dental practice or care home near Marlow Common, clean ventilation matters as much to you as to a hospital like Marlow Community Hospital (about 1.7 miles east). For schools like Spinfield School, the holidays are the usual time to inspect and clean ventilation.

What happens on the day
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. From there, it takes from a few hours for a compact unit to a day or more for a large one. Photos of the system and how to reach it help us plan a visit to Marlow Common.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Let us know about parking and loading
- Let us know how we reach the system, including roofs, risers and plant rooms
- Clear loose items from the work area

Honest limits
We will not sell you work that does not address the problem, so here are the limits:
- Dirty ducts beyond the unit itself
- Controls and BMS settings that run the unit
- A system that is undersized for the building
If you are not sure, just call us on 0345 646 2711 or email us and we’ll give you a straight answer before booking.
Where we work
- Internal panels
- Dampers and louvres
- Heating and cooling coils
- Supply and extract fans
- Drain trays
- Filter sections
What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Between visits
So the system stays in good health:
- Keep filter changes on time and recorded
- Diary the inspection date recommended in the report
- Flag stale or damp smells in the supply air
- Report water on the plant room floor
The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
Questions from Marlow Common
Do you do school ventilation cleaning in Marlow Common in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Marlow Common, the Food Standards Agency lists about 6 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you work in Marlow Common outside opening hours?
Yes, evening, overnight and weekend work is normal for us. It means the site in Marlow Common keeps running as normal. Tell us your opening hours when you ask for a quote.
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.
Can you price the work without visiting?
Typically, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote typically follows within one working day. If photos are not enough, we will survey first.
Can you look after several sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
Do you offer emergency callouts?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
How long will the unit be out of action?
It takes from a few hours for a compact unit to a day or more for a large one. The unit’s size and condition make the biggest difference, and we’ll confirm the time when we quote.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Why act early in Marlow Common
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. In a small place like Marlow Common, a system that fails can take a site out of use.
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before we start.
Why us?
- Every visit written up, with pictures
- In business since 2009
- Accredited under CHAS and SafeContractor, with ISO 9001
- Fully insured

Different parts, different methods
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe with your site team.

What else we do in Marlow Common
What affects the cost of AHU cleaning
The diagnosis comes before the price. We look at:
- How easy every part is to reach
- The number of sites or systems
- Travel, parking and unloading
- Whether it’s a one-off visit or part of a schedule
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, ring 0345 646 2711 or drop us a line for straight advice and a fixed quote.
What we need to know
Many jobs can be priced from photos and some basics. Send what you can of the following:
- A few general shots of the system
- The paperwork from the last visit, if you have it
- Detail shots of panels, filters and grilles
- When the site is open and when it’s quiet
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
