Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, 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 visits at different addresses can be planned together and kept on a regular cycle.
About our AHU cleaning in Jacob's Post
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. Typical jobs include dirty coils holding back the airflow and units that have only ever had filter changes, on drain trays, dampers and louvres and heating and cooling coils.
In a village or hamlet like Jacob's Post, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What AHU cleaning looks like in Jacob's Post
There are about 5 schools, colleges and universities and about 25 care, childcare and hospital premises on the FSA’s food hygiene register in and around Jacob's Post, up to about a mile and a half out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Jacob's Post is about 37 miles from central London, well within the area we cover across London and the South East. Visits are booked around your hours, evenings and weekends included. For Jacob's Post, the closest hospital is The Dene Hospital, roughly 1.2 miles west. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.

Common questions in Jacob's Post
Can you come to Jacob's Post after we close?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Just give us a ring on 0345 646 2711 or email us with your opening times and we’ll plan around them.
Do you do school ventilation cleaning in Jacob's Post in the summer holidays?
Yes, out-of-term visits are normal for schools. With about 5 schools and colleges on the FSA’s register within roughly a mile and a half of Jacob's Post, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
How much does AHU cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before work begins.
What if parts of the system cannot be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
How much notice should we give?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
Are you fully insured?
Yes. We carry full insurance and have been trading since 2009.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Looking after it afterwards
A little care between visits keeps the system in better shape. Our advice:
- Keep the certificate and photo report with the plant records
- Report water on the plant room floor
- Stick to the filter change plan
- Don’t store bins or materials near the intake
Restart the unit with your site team or maintenance contractor once we’ve finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
What the work involves, part by part
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
How the visit works
Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. If the van will struggle with a lane or gateway near Jacob's Post, let us know and we will plan around it.
- 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.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about site rules, permits or sign-in

Staff cleaning versus specialist work
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
What affects the quote in Jacob's Post
Every site gets its own quote. These are the things that affect it:
- Travel, parking and unloading
- Working hours and out-of-hours timing
- How big the system is
- Access, including roofs, risers and ceiling voids
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.
Asking for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Where the site is and what kind of site it is
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
- The paperwork from the last visit, if you have it

What we’re called out for in Jacob's Post
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and the finer material travels on.
Keep an eye out for any of the following:
- Debris and leaves in the fresh air intake
- Dirty coils holding back the airflow
- Drain trays holding standing water
- Fan sections that haven’t been cleaned in years
Hospitals such as The Dene Hospital (about 1.2 miles west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Jacob's Post are no different.
