Managing agents and facilities teams in Marley
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
About our AHU cleaning in Marley
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. The work covers internal panels, dampers and louvres and supply and extract fans, and people most often call us about air handling units with blocked filters and stale or musty smells from the ventilation.
Somewhere as small as Marley, 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.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Between visits
Simple habits between visits make a real difference. Our advice:
- Keep inspection doors on the unit in good order
- Plan the next inspection before the last report gets filed away
- Clear leaves and litter away from the intake
- Store the TR19 paperwork where auditors can find it
Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
AHU cleaning in Marley: local notes

Busy, occupied buildings like these are where clean supply air matters most. Marley, about 57 miles from central London, is within our usual area. Evening, overnight and weekend visits are all possible. About 4.3 miles north-west of Marley is Kent and Canterbury Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Healthcare ventilation, from large hospitals like Kent and Canterbury Hospital (about 4.3 miles north-west) to small clinics, depends on clean filters, coils and ducts.

What we’re called out for in Marley
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Marley, that is air they breathe for hours at a time.
These are the problems we see most often:
- Dirty filters cutting the airflow
- Air handling units never cleaned inside
- Plant that needs cleaning after a refit
- Rooms that smell stuffy when the system runs
Classrooms and halls at schools such as Barham Church of England Primary School are easiest to work in when pupils are away.
Before booking anyone
- Whether the figure could change on the day
- What paperwork you get at the end
- Proof of accreditation you can verify
- Whether they’re fully insured
Fixed quotes for AHU cleaning in Marley
Before we fix a price, we need to know a few things. We look at:
- One-off work versus a regular cycle
- The condition of the system
- Access, including roofs, risers and ceiling voids
- Travel, parking and unloading
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- Any previous report or certificate
- Any symptoms, from odd noises to smells or leaks
- Photos showing the whole system and its surroundings
- Any access panels or hatches you can see
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before work begins.
Part by part
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that will not bend or flatten the fins.
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with photos so you can decide on any repairs.
How the visit works
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, which takes one overnight shift for many single units, with bigger plant phased. Seeing the system in photos first means the trip to Marley can be planned properly.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
How to prepare
- Let us know about parking and loading
- Move anything stored near the system
- Tell us about site rules, permits or sign-in
Get a fixed quote
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

Marley: your questions answered
Do you cover smaller places like Marley?
Yes. Villages and rural sites across the South East are part of our work, Marley included. A survey first, from pictures or a visit, means we arrive with the right kit.
Can ventilation in schools around Marley be cleaned out of term?
Yes, holiday work suits schools best. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Marley. Send us your term dates when you ring 0345 646 2711 or drop us a line, and we’ll fit the work in.
How much does AHU cleaning cost?
We do not publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before we start.
What do you need from me for a quote?
A short description and a few photos, with the address and opening hours. If we need more, we will ask.
Where does the waste go?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.

How long will the unit be out of action?
Cleaning takes anything from half a day for one small unit to several shifts for a plant room full of them. Large plant can be split over several shifts, so phone us on 0345 646 2711 or send us an email to talk it through.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
