How we handle AHU cleaning in Walter's Green
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. If you’re dealing with plant that has been serviced but not cleaned and air handling units with blocked filters, we can put it right.
For a building in or near Walter's Green, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
A written report with pictures follows each visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Part by part
Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.

Common problems we fix in Walter's Green
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that is where slime and odours start.
Any of these means the system needs a check-up:
- Air handling units due a clean after building work
- Drain trays holding standing water
- Debris and leaves in the fresh air intake
- Air handling units never cleaned inside
Hospitals such as Kent and Sussex Hospital (about 4.3 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Walter's Green are no different.
What to look for in a quote
- What hours they’ll be on site
- If the quote is a fixed price or an estimate
- What insurance they carry
- Which accreditations they hold, and whether you can check them
How it works
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. From there, it takes a single shift for a typical unit, longer for large or heavily soiled ones. We agree a date with you, plan the drive to Walter's Green and turn up when the site is quiet.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Before we arrive
- Let us know about permits to work or site inductions
- Arrange a key holder or contact on site
- Tell us where we can park and unload
Get a fixed quote
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before we start.
Advice
What affects the quote in Walter's Green
The price is fixed before any work begins. It takes into account:
- The condition we find in the survey
- Any permits to work or inductions
- A single visit or a regular plan
- How big the system is
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.
What to send for a quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Any symptoms, from odd noises to smells or leaks
- Any access panels or hatches you can see
- The site address and the type of premises
- The roof, plant room or outside wall the system runs to
Getting a quote doesn’t take long. 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.
Walter's Green questions
Can you come to Walter's Green after we close?
Yes, evening, overnight and weekend work is normal for us. The work in Walter's Green can fit around your hours. Let us know the hours you’re closed and we’ll book within them.
Will you come out to Walter's Green?
Yes, Walter's Green is part of our area, however small the site. A survey first, from photos or a visit, means we arrive with the right kit.
Do you offer emergency callouts?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
What should I send you?
Some pictures and a quick description of the system, with the address and opening hours. We will ask for anything else we need.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Can you price the work without visiting?
Yes, where the photos show enough. If not, a site survey comes first, and the quote follows that.
Will we get paperwork for the AHU clean?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
Landlords, agents and facilities managers
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
Leave it or put it right?
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. Rural sites cannot always move to another kitchen or room when something fails.
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before any work starts.
