AHU cleaning for kitchens and businesses in Church Hanborough
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. If you’re dealing with dirty fans and fan housings and coils clogged with dust and debris, we can put it right, from filter sections, supply and extract fans and drain trays onwards.
For a building in or near Church Hanborough, access is agreed in advance and the visit is planned around the journey.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Questions from Church Hanborough
Do you cover smaller places like Church Hanborough?
Yes. Villages and rural sites across the South East are part of our work, Church Hanborough included. Just mention lanes, gates or anything else about the site when you book.
Do you work at weekends in Church Hanborough?
Yes, out-of-hours work is a big part of what we do. That way a site in Church Hanborough doesn’t have to lose a day’s trading. Just give us a ring on 0345 646 2711, or send details by email with your opening times and we’ll plan around them.
Do you do ventilation duct cleaning too?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
What does TR19 mean?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply call us on 0345 646 2711 or send us an email.
Are you fully insured?
Yes. Full insurance covers our work, and we have been trading since 2009.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
What affects the quote in Church Hanborough
The price is fixed before any work begins. It takes into account:
- Whether we need access equipment or extra panels
- What state the system is in
- When the work can happen, such as evenings, overnight or weekends
- Whether several sites go on one quote
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 play a part.
What to send for a quote
We can often survey from pictures. The most useful are:
- How we’d reach plant on a roof or in a plant room
- Your opening hours and when the area is out of use
- Photos showing the whole system and its surroundings
- Close-ups of filters, grilles, hatches or access panels
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before we start.
When to call us in Church Hanborough
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Church Hanborough, that’s air they breathe for hours at a time.
Clients typically contact us after spotting one of these:
- Drain trays holding standing water
- Dirty filters cutting the airflow
- Dirty coils holding back the airflow
- Debris and leaves in the fresh air intake
If you manage offices or shops near Hanborough station, their ventilation can be inspected and cleaned out of hours.
What to look for in a quote
- Exactly which parts of the system are covered
- Whether the figure could change on the day
- What insurance they carry
- Whether inaccessible sections are listed on the report
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.

How the job changes from site to site
Fans and fan sections
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins are not damaged.
Looking after it afterwards
Good habits slow the build-up between visits. Our tips:
- Store the TR19 paperwork where auditors can find it
- Make sure the unit’s access doors open easily
- Watch for drips or damp patches near the plant
- Look at the condensate drain whenever the unit is serviced
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
How it works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. A few pictures of the system help us make the most of a visit to a place like Church Hanborough.
