AHU cleaning for kitchens and businesses in Colt's Hill
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. The work covers filter sections, dampers and louvres and drain trays, and the jobs we see most are plant that needs cleaning after a refit and units that have only ever had filter changes.
For a building in or near Colt's Hill, access is agreed in advance and the visit is planned around the journey.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What the work involves, part by part
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so you can decide on any repairs.
What we do, step by step
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. If the van will struggle with a lane or gateway near Colt's Hill, let us know and we’ll plan around it.
- 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.

Advice
Common problems we fix in Colt's Hill
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Most sites get in touch after spotting one of these:
- Plant that needs cleaning after a refit
- Stale or musty smells from the ventilation
- Blocked condensate drains and slimy trays
- Dust built up on fan impellers
School buildings such as Capel Primary School are typically done in the holidays, so classrooms are not disturbed.

Why it’s worth doing now in Colt's Hill
Dirt left in an air handling unit doesn’t stay in the unit. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. It’s simpler to plan the work at Colt's Hill now than to arrange it in a hurry later.

FAQs for Colt's Hill
Can ventilation in schools around Colt's Hill be cleaned out of term?
Yes, and it’s the easiest time to do it. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Colt's Hill, it pays to plan holiday dates ahead. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you cover smaller places like Colt's Hill?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
What do you do with what you remove?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
Is there a report after cleaning?
Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.
What happens if you can’t reach some of it?
Anything we can’t reach goes on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
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.
Do you work evenings or weekends?
Yes. We work evenings, overnight and weekends, so the building keeps running in the day.
Keeping the system healthy
Once we’ve finished, these simple steps help:
- Book the next check in line with the report
- Make sure the unit’s access doors open easily
- Store the TR19 paperwork where auditors can find it
- Keep filter changes on time and recorded
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
