AHU cleaning in Westmeston
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. If you have fan sections that haven’t been cleaned in years and dirty coils holding back the airflow, we can help.
Somewhere as small as Westmeston, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
The sign-off is always in writing: a dated report with pictures 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 your team can do, and what needs us
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
How it works
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. Photos of the system and how to reach it help us plan a visit to Westmeston.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Move anything stored near the system
- Let us know how we reach the system, including roofs, risers and plant rooms

Ventilation in Westmeston buildings
We cover Westmeston, about 41 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours. About 4.7 miles north-west of Westmeston is The Dene Hospital, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Classrooms and halls at schools such as Ditchling (St Margaret's) Church of England Primary School are easiest to work in when pupils are away.

What the work involves, 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.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
Questions from Westmeston
Do you work in villages like Westmeston?
Yes, we work in villages as well as towns, and Westmeston is covered. Let us know about access, parking and anything unusual about getting there when you book.

How far ahead should we book?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
What happens if you can’t reach some of it?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
Do you look at the system first?

Do you have insurance?
Yes. We are fully insured, and the details are available on request.
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 talk you through the next steps.

Looking after it afterwards
To keep the system working properly between visits:
- File each AHU report in the maintenance log
- Note any water around the unit or leaks below it
- Look at the condensate drain whenever the unit is serviced
- Keep inspection doors on the unit in good order
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
Do you need AHU cleaning in Westmeston?
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Keep an eye out for these warning signs:
- Plant that has been serviced but not cleaned
- Fan sections that haven’t been cleaned in years
- Condensate trays that will not empty
- Dirty filters cutting the airflow
Healthcare buildings such as The Dene Hospital, about 4.7 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Westmeston, yours matters too.
Before you book anyone
- Whether the figure could change on the day
- Whether they’re fully insured
- If they look at the system before pricing
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
What affects the cost of AHU cleaning
You will get a fixed price before work begins. It takes into account:
- Site rules, permits and inductions
- How easy every part is to reach
- Whether several sites go on one quote
- One-off work versus a regular cycle
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
Asking for a quote
To speed up the quote, please include:
- Any access panels or hatches you can see
- The site address and the type of premises
- Your last certificate, test record or report
- Where the plant sits or the system leaves the building, such as a roof or outside wall
If you need AHU cleaning in Westmeston, phone us on 0345 646 2711, or send details by email. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. We usually send a fixed quote within one working day.
