AHU cleaning for kitchens and businesses in Kingsfold
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. We’re often asked to deal with units that have only ever had filter changes and coils clogged with dust and debris, across internal panels, drain trays and heating and cooling coils.
Work in a small place like Kingsfold starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Nothing is signed off by word of mouth: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Why act early in Kingsfold
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, particularly where damp has made it stick. A fault that closes a site in a village like Kingsfold affects everyone who depends on it.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.
Why Kingsfold businesses choose us
- One number for every site across the South East and London
- Every job surveyed first
- Trading since 2009
- Accredited under CHAS and SafeContractor, with ISO 9001

How the visit works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. On site, it takes from a few hours for a compact unit to a day or more for a large one. If you can send pictures, we can arrive in Kingsfold knowing what to expect.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- 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
- Have your last certificate or report to hand
- Arrange a key holder or contact on site
- Let us know how we reach the system, including roofs, risers and plant rooms
Ask for a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.

In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.

Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Stick to the filter change plan
- Watch for drips or damp patches near the plant
- Report musty smells from the vents right away
- Diary the inspection date recommended in the report
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

What AHU cleaning can’t fix
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Mechanical faults with motors, belts or bearings
- Controls and BMS settings that run the unit
- A system that is undersized for the building
Not sure which it is? You can give us a ring on 0345 646 2711 or email us and we’ll tell you honestly before booking.
Parts of the system we cover
- Internal panels
- Drain trays

Common questions in Kingsfold
Do you cover smaller places like Kingsfold?
Yes. Kingsfold is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work overnight in Kingsfold?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Each site gets its own report and pictures.
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.
Where does the waste go?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it does not spread.
Do you repair air handling units?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
How long does it take to clean an air handling unit?
As a guide, it takes one overnight shift for many single units, with bigger plant phased. We plan the shutdown around that, out of hours if needed.
What should I send you?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. Then call 0345 646 2711 or drop us a line.
When to call us in Kingsfold
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
Any of these means the system needs a check-up:
- Blocked condensate drains and slimy trays
- Coils clogged with dust and debris
- Intake sections clogged with outdoor debris
- Rooms that smell stuffy when the system runs
Horsham Hospital, about 3.2 miles south, is the nearest hospital to Kingsfold, and healthcare sites of every size need their supply air kept clean.

Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare in Kingsfold and across West Sussex. Work can be phased by floor, building or site to keep disruption down.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
