AHU cleaning for kitchens and businesses in Littleton Common
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. We are often asked to deal with units that have only ever had filter changes and drain trays holding standing water, across heating and cooling coils, dampers and louvres and filter sections.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

What a clean won’t put right
A few issues sit outside what this work can do:
- Dirty ducts beyond the unit itself
- Airflow problems caused by the system’s design
- Faulty motors, drives or bearings
If you are not sure, just phone us on 0345 646 2711, or email photos and we’ll give you a straight answer before booking.
What the work covers
- Dampers and louvres
- Heating and cooling coils
- Drain trays
- Internal panels
- Supply and extract fans
- Filter sections
Keeping the system healthy
How long the results last depends on use and care. We suggest:
- Note any water around the unit or leaks below it
- Plan the next inspection before the last report gets filed away
- Store the TR19 paperwork where auditors can find it
- Keep filter changes on time and recorded
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes from a few hours for a compact unit to a day or more for a large one, and the area is cleaned down before we leave. Seeing the system in photos first means the trip to Littleton Common can be planned properly.
- We look at the unit and the plant area during the survey.
- 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
- Tell us the best time to work, such as after service or at a weekend
- Dig out any earlier paperwork for the system
- Plan for cooking equipment or plant to be off before we arrive

Different parts, different methods
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with pictures so repairs can be planned.
What your team can do, and what needs us
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
What we are called out for in Littleton Common
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
If you notice any of these, it’s worth a diagnosis:
- Filters that are clogged or overdue
- Units needing a clean before a new tenant or handover
- Dust-coated heating and cooling coils
- Debris and leaves in the fresh air intake
Healthcare buildings such as Ashford Hospital, about 1.8 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Littleton Common, yours matters too.

What happens if it’s left?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, particularly where damp has made it stick. If the system at a site near Littleton Common fails, there may be nowhere nearby to move to.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You will have a fixed price before we start.

Do you do school ventilation cleaning in Littleton Common in the summer holidays?
Yes, and it’s the easiest time to do it. There are about 16 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Littleton Common. Booking early in the term gives the best choice of holiday dates.
Will you come out to Littleton Common?
Yes. Littleton Common is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
How much notice should we give?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Every site has its own report.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can survey both on the same visit.
Will you repair the fan or motor?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
