AHU cleaning in Kemsing, done properly
Our AHU cleaning covers sites in Kemsing and the rest of Kent, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you are dealing with air handling units due a clean after building work and leaves and litter drawn into the unit, we can put it right, from dampers and louvres, internal panels and drain trays onwards.
Smaller buildings around Kemsing often keep their ventilation units in a roof void or plant cupboard, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

FAQs for Kemsing
Do you work at weekends in Kemsing?
Yes, we can come after you close and finish before you open. The work in Kemsing can fit around your hours. Just ring 0345 646 2711, or email photos with your opening times and we will plan around them.
Is Kemsing within the area you cover?
Yes, Kemsing is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
What does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote, usually ready within one working day.
Do you have a 24/7 line?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.
Where does the waste go?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We do not leave it behind.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What affects the quote in Kemsing
Some jobs are bigger than they look, and some smaller. What affects the quote:
- A single visit or a regular plan
- Whether several sites go on one quote
- Working hours and out-of-hours timing
- Where the site is and how we reach it
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
What we need to know
We can often survey from photos. The most useful are:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- How we’d reach plant on a roof or in a plant room
- Any access panels or hatches you can see
- Your last certificate, test record or report
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
What AHU cleaning cannot fix
We won’t sell you work that doesn’t address the problem, so here are the limits:
- The supply and extract ducts, quoted separately
- Ventilation that was badly designed in the first place
- Controls and BMS settings that run the unit
Not sure which it is? You can phone us on 0345 646 2711 or email us and we’ll tell you honestly before booking.
Where we work
- Internal panels
- Filter sections
- Drain trays
- Supply and extract fans
- Dampers and louvres
- Heating and cooling coils
In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Day-to-day cleaning is something your team can do: 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.
Part by part
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
What we are called out for in Kemsing
Whatever surrounds a building in Kemsing, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and the finer material travels on.
The symptoms we’re asked about most include:
- Air handling units never cleaned inside
- Plant that needs cleaning after a refit
- Dust built up on fan impellers
- Intake sections clogged with outdoor debris
Wherever a school like Kemsing Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
What to look for in a quote
- Whether they recommend a next date
- Whether a written report and photos are included
- When they can work, and whether that is outside your opening hours

AHU cleaning in Kemsing: local notes
The FSA’s food hygiene register lists about 11 schools, colleges and universities and about 3 hospitals, care homes and childcare premises with registered kitchens or food service across Kemsing and its immediate surroundings (about a mile and a half). Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 19 miles out from central London, Kemsing is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site. About 1.6 miles south-west of Kemsing is Sevenoaks Hospital, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.

How it works
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Around Kemsing, access is normally simpler than in a town centre, though gates and roof access are worth mentioning.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Tell us where we can park and unload
- Arrange a key holder or contact on site
Ask for a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before we start.
Advice
Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Keep inspection doors on the unit in good order
- Do not ignore odours coming through the grilles
- Keep the area around the fresh air intake clear
- Keep filter changes on time and recorded
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. They belong in the plant or maintenance log.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
