AHU cleaning for kitchens and businesses in South Malling
We clean air handling units for buildings in South Malling and across East Sussex, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers filter sections, internal panels and supply and extract fans, and people most often call us about fan sections that haven’t been cleaned in years and units that have only ever had filter changes.
In a smaller place like South Malling, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Even a small system collects dust in its ducts and filters.
The paperwork matters as much as the work. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

South Malling buildings and their air
Going by the FSA’s register, there are about 6 schools, colleges and universities and about 4 caring premises (care homes, nurseries and hospitals) serving food within roughly a mile and a half of the centre of South Malling. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. South Malling’s nearest hospital, Lewes Victoria Hospital, is about 0.8 miles south-west. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. At about 43 miles from central London, South Malling sits well inside the area we cover. A survey and a fixed quote come first, then the visit at a time that suits you.
For schools like South Malling CofE Primary and Nursery School, the holidays are the usual time to inspect and clean ventilation. If you manage offices or shops near Lewes station, their ventilation can be inspected and cleaned out of hours. Hospitals such as Lewes Victoria Hospital (about 0.8 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near South Malling are no different.

What else we do in South Malling
Part by part
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that will not bend or flatten the fins.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
When it’s something else
Some problems need a different service or another trade:
- Leaking heating or cooling coils
- Breakdowns that need a mechanical engineer
- Controls and BMS settings that run the unit
If in doubt, call us on 0345 646 2711, or email photos and we’ll say what we think.
Parts of the system we cover
- Filter sections
- Supply and extract fans
- Drain trays
- Heating and cooling coils
- Dampers and louvres
- Internal panels
How it works
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes anything from half a day for one small unit to several shifts for a plant room full of them, and the area is cleaned down before we leave. Visits to a place like South Malling are planned ahead, so we arrive with what the survey says the job needs.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure someone can let us in and lock up afterwards
- Let us know about permits to work or site inductions

What your team can do, and what needs us
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
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 don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
How we price AHU cleaning
We do not publish a price list, because no two systems are the same. The quote depends on:
- How big the system is
- The condition of the system
- A single visit or a regular plan
- Any permits to work or inductions
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.
Asking for a quote
There’s no need for technical detail. Just send:
- The postcode and the type of business
- Your last certificate, test record or report
- Detail shots of panels, filters and grilles
- A few general shots of the system
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
Multi-site and managed buildings
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.
Your questions about AHU cleaning in South Malling
Can you work in South Malling outside opening hours?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Just call us on 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Do you work in villages like South Malling?
Yes. Villages and rural sites across the South East are part of our work, South Malling included. Let us know about access, parking and anything unusual about getting there when you book.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Which accreditations do you hold?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
How long does an AHU clean take?
Typically the clean takes half a day to a full day per unit, with large plant planned over several shifts. The shutdown is planned to fit, including evenings or weekends.
What happens if you can’t reach some of it?
We record them on the report, with pictures where possible, and we explain what access is needed, such as extra access panels in ductwork.
Do you clean the ductwork as well?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can quote for both.
How much notice should we give?
Earlier is better, especially for out-of-hours work. We usually quote within one working day, and emergencies are covered by our 24/7 line.
What happens if it’s left?
Stuffy rooms and stale smells in a building in South Malling can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. A planned visit to South Malling fits your hours; an emergency doesn’t.
What you pay depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.
