AHU cleaning for kitchens and businesses in Borough Green
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. The work covers supply and extract fans, internal panels and drain trays, and people most often call us about blocked condensate drains and slimy trays and debris and leaves in the fresh air intake.
For a building near Borough Green, the visit is planned around how it’s used, and the journey is planned ahead. The method doesn’t change: inspect first, clean, then record what was done.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What else we do in Borough Green
What we do, step by step
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes from a few hours for a compact unit to a day or more for a large one. Tell us about any gates, ladders or locked plant areas at your site near Borough Green when you book.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Mention any locked doors, roof access or ceiling voids
- Let us know about permits to work or site inductions
- Let us know about parking and loading

Advice
For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
What your team can do, and what needs us
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, which is where we come in.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Questions from Borough Green
Is Borough Green within the area you cover?
Yes, we work in villages as well as towns, and Borough Green is covered. The journey is planned ahead, so a few details about the route help.
Can a school’s ventilation in Borough Green be done out of term time?
Yes, out-of-term visits are normal for schools. There are about 10 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Borough Green. Tell us your holiday dates and we will book the visit for when the site is empty.
What do you clean inside the unit?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
Do you offer maintenance contracts?
Yes, of course. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Can you price the work without visiting?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we typically come back within one working day. Some sites still need a visit, and we will say so.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
What affects the cost of AHU cleaning
The survey tells us what the work involves. We look at:
- Any permits to work or inductions
- The condition we find in the survey
- Whether we need access equipment or extra panels
- A single visit or a regular plan
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Photos showing the whole system and its surroundings
- Your last certificate, test record or report
- The roof, plant room or outside wall the system runs to

What the work involves, part by part
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
What we are called out for in Borough Green
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
Look out for these warning signs:
- Debris and leaves in the fresh air intake
- Dirty fans and fan housings
- Air handling units with blocked filters
- Plant that has been serviced but not cleaned
Workplaces around Borough Green & Wrotham station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
