How we handle AHU cleaning in Tonbridge
Our AHU cleaning covers sites in Tonbridge and the rest of Kent, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. We are often asked to deal with coils clogged with dust and debris and dirty fans and fan housings, across drain trays, supply and extract fans and heating and cooling coils.
Many schools and offices in a town like Tonbridge have a mix of older and newer ventilation. An inspection shows which parts need cleaning.
It’s worth checking any contractor’s accreditations. 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.

Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. 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.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Honest limits
It’s worth knowing the limits before booking:
- Airflow problems caused by the system’s design
- Damaged coils beyond cleaning
- Dirty ducts beyond the unit itself
Not sure which it is? You can phone us on 0345 646 2711 or use the quote form and we’ll tell you honestly.

What affects the quote in Tonbridge
Before we fix a price, we need to know a few things. We look at:
- Any permits to work or inductions
- What state the system is in
- How many systems or sites are involved
- How big the system is
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.
What to send for a quote
Many jobs can be priced from photos and some basics. Useful things to send:
- Your opening hours and when the area is out of use
- Any previous report or certificate
- Problems your staff have spotted
- The roof, plant room or outside wall the system runs to
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

Between visits
Results last longer with the right care. Here’s what we suggest:
- Watch for drips or damp patches near the plant
- Stick to the filter change plan
- Diary the inspection date recommended in the report
- File each AHU report in the maintenance log
The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
How the visit works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Three things shape a visit in Tonbridge: when you are closed, where we can park and how we get to the system.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Find the previous report, if there is one
- Move anything stored near the system
- Let us know when the site is closed or quiet
Getting a quote
Quoting starts with a diagnosis, either from photos 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 any work starts.
Advice
In-house cleaning or a specialist?
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, and that is where we come in.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Common questions in Tonbridge
Can a school’s ventilation in Tonbridge be done out of term time?
Yes. The holidays are the usual time for school work. With about 25 schools and colleges on the FSA’s register within roughly a mile and a half of Tonbridge, it pays to plan holiday dates ahead. You can call 0345 646 2711 or use the quote form with the dates the site is empty.
Can you come to Tonbridge after we close?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Just ring 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
How often do AHUs need cleaning?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we will suggest an interval after the first clean.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Do you have insurance?
Yes, we are fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it does not spread.
What should I send you?
Some pictures and a quick description of the system, with the address and opening hours. If we need more, we will ask.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
Tonbridge buildings and their air

Busy, occupied buildings like these are where clean supply air matters most. About 1.4 miles south of Tonbridge is Tonbridge Cottage Hospital, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. About 26 miles out from central London, Tonbridge is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site.
Classrooms and halls at schools such as New Beacon School are easiest to work in when pupils are away. Hospitals such as Tonbridge Cottage Hospital (about 1.4 miles south) show how much a building can rely on clean ventilation, and smaller healthcare sites near Tonbridge are no different.

Different parts, different methods
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with pictures.
