About our AHU cleaning in Rose Green
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. The work covers dampers and louvres, heating and cooling coils and internal panels, and common reasons people get in touch are plant that has been serviced but not cleaned and drain trays holding standing water.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
The sign-off is always in writing: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
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 can diagnose it and quote.
What happens if it’s left?
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. That makes the next inspection of a building in Rose Green simpler. Rural sites can’t always move to another kitchen or room when something fails.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.

Part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
Questions from Rose Green
Is Rose Green in your area for AHU cleaning?
Yes, we work in Rose Green and the places around it. A fixed quote normally follows within one working day of the survey details.
Is Rose Green within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Rose Green included. The journey is planned ahead, so a few details about the route help.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We do not leave it behind.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Can you clean without disrupting the building?
Yes, if daytime working is not practical. We plan the shutdown window with you.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
Do you have a 24/7 line?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
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.
Between visits
Think of this as the after-treatment advice, short and simple:
- Report stiff or damaged access doors
- Keep the area around the fresh air intake clear
- Look at the condensate drain whenever the unit is serviced
- Keep filter changes on time and recorded
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
Signs you need AHU cleaning in Rose Green
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Keep an eye out for these warning signs:
- Filters that are clogged or overdue
- Fan sections that haven’t been cleaned in years
- Rooms that smell stuffy when the system runs
- Units that have only ever had filter changes
If you manage a school such as Chappel Church of England Controlled Primary School, ventilation cleaning is best booked for the holidays.

The process
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. Most of the time goes on the work itself, and that takes anything from half a day for one small unit to several shifts for a plant room full of them. Photos of the system and how to reach it help us plan a visit to Rose Green.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Before we arrive
- Mention any sign-in, permit or induction we need
- Have your last certificate or report to hand
- Make sure equipment near the work can be switched off and left to cool
