What AHU cleaning looks like in Coursehorn
There are about 5 schools, colleges and universities on the FSA’s food hygiene register within 1.5 miles or so of the middle of Coursehorn. Busy, occupied buildings like these are where clean supply air matters most. Coursehorn’s nearest hospital, Benenden Hospital, is about 2.8 miles east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. At about 40 miles from central London, Coursehorn sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site.
Healthcare buildings such as Benenden Hospital, about 2.8 miles east, depend on their ventilation; if you manage a surgery, clinic or care home near Coursehorn, yours matters too.

AHU cleaning for kitchens and businesses in Coursehorn
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. The work covers heating and cooling coils, filter sections and internal panels, and the jobs we see most are debris and leaves in the fresh air intake and air handling units never cleaned inside.
Work in a small place like Coursehorn starts with agreeing access and timings.
For insurers and inspectors, the record counts. 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
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.
Coursehorn: your questions answered
Do you work in villages like Coursehorn?
Yes. Coursehorn is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you come to Coursehorn after we close?
Yes, nights and weekends are routine for us. The work in Coursehorn can fit around your hours. Your opening times are the first thing we ask for.
Can you set up regular visits?
Yes, of course. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.
What if parts of the system cannot be reached?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Do you give a certificate after the clean?
Yes, both a certificate and a report with photos. The report also suggests when the unit should next be inspected.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
When to call us in Coursehorn
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.
If you notice any of these, it’s worth a diagnosis:
- Intake sections clogged with outdoor debris
- Plant that needs cleaning after a refit
- Coils clogged with dust and debris
- Rooms that smell stuffy when the system runs
School buildings such as Cranbrook School are usually done in the holidays, so classrooms aren’t disturbed.
Before booking anyone
- Whether the figure could change on the day
- How they set the interval to the next visit
- Whether inaccessible sections are listed on the report
- How VAT is shown on the quote
How it works
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a single shift for a typical unit, longer for large or heavily soiled ones. Seeing the system in photos first means the trip to Coursehorn can be planned properly.
- We agree a shutdown window that suits the building.
- We take before photos 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.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Find the previous report, if there is one
- Let us know about permits to work or site inductions
Get a fixed quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Fixed quotes for AHU cleaning in Coursehorn
The survey tells us what the work involves. The main factors are:
- The size of the system
- When the work can happen, such as evenings, overnight or weekends
- Travel, parking and unloading
- The condition of the system
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.
Asking for a quote
You don’t need the technical terms. It helps if you can send:
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
- The roof, plant room or outside wall the system runs to
- Problems your staff have spotted
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To get going, phone us on 0345 646 2711, or send details by email.
What a clean won’t put right
A few issues sit outside what this work can do:
- Coils that are corroded or leaking and need replacing
- The supply and extract ducts, quoted separately
- A system that’s undersized for the building
If you’re not sure, just call 0345 646 2711 or drop us a line and we will give you a straight answer before you book.
Parts of the system we cover
- Filter sections
- Heating and cooling coils
- Dampers and louvres
- Supply and extract fans
- Internal panels
- Drain trays
Aftercare tips
Here’s the after-treatment advice, in brief:
- Make sure condensate is draining away
- Keep the area around the fresh air intake clear
- Plan the next inspection before the last report gets filed away
- File each AHU report in the maintenance log
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
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.
