Signs you need AHU cleaning in Minnow End
Filters that are not changed or cleaned on time clog up, 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.
Clients usually contact us when they notice something like this:
- Drain trays holding standing water
- Debris and leaves in the fresh air intake
- Units needing a clean before a new tenant or handover
- Units that have only ever had filter changes
Hospitals such as Broomfield Hospital (about 1.1 miles south) show how much a building can rely on clean ventilation, and smaller healthcare sites near Minnow End are no different.

AHU cleaning for kitchens and businesses in Minnow End
Our AHU cleaning covers sites in Minnow End and the rest of Essex, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. Common call-outs are for dirty filters cutting the airflow and debris and leaves in the fresh air intake, on heating and cooling coils, internal panels and filter sections.
In a village or hamlet like Minnow End, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Nothing is signed off by word of mouth: a dated report with photos 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.

Part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Ventilation in Minnow End buildings
Food Standards Agency data includes about 5 schools, colleges and universities and about 7 caring premises (care homes, nurseries and hospitals) in Minnow End and the streets around it, up to about 1.5 miles out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Broomfield Hospital is the nearest hospital, about 1.1 miles south of Minnow End. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. At about 31 miles from central London, Minnow End sits well inside the area we cover. A survey and a fixed quote come first, then the visit at a time that suits you.
For schools like Chelmer Valley High School, the holidays are the usual time to inspect and clean ventilation.

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.

Why act early in Minnow End
Dirt left in an air handling unit doesn’t stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. With notice, the visit to Minnow End can be fitted around your bookings and events.
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before work begins.

Multi-site and managed buildings
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
How the visit works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Visits to a village like Minnow End are booked in advance, at a time that suits whoever runs the site.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Arrange a key holder or contact on site
- Have your last certificate or report to hand
How to get a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before we start.

How we price AHU cleaning
The diagnosis comes before the price. We look at:
- Any permits to work or inductions
- When the work can happen, such as evenings, overnight or weekends
- How easy every part is to reach
- The scale of the work
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
What to send for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Problems your staff have spotted
- When the site is open and when it’s quiet
- Wide photos of the system and the area around it
- The roof, plant room or outside wall the system runs to
We do not publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To start, call 0345 646 2711 or use the quote form.
